Well, the SIAIs strictly shouldn't be here, because they were built and flown (and ordered for series production).
For the Macchi bifusoliera and the Corsaro, refer here http://www.secretprojects.co.uk/forum/index.php/topic,2411.msg20201.html#msg20201, for the SM-91, here http://www.secretprojects.co.uk/forum/index.php/topic,2737.msg21883.html#msg21883 . Since I wrote that post, I have to make a correction (and update from my research): the final SM-91, ordered in March 1943 was to be a night-fighter and had special exhaust covers to mask the flames from the hot gases. The Sm-92 was to be the zerstorer.
 
You are right
The SM 91 & SM 92 were real airplanes

So, more of a scare weapon rather than a serious attempt at a defensive one? Aiming it by aiming the entire aircraft must have been interesting.

There was an article about tests with such (fixed) weapons in German aircraft in an Luftfahrt International
issue. It was said, that aiming actually was quite easy, if a "Rückblickfernrohr" (rear view telescope/sight)
was installed.

I think with the aimer being offset in the port fuselage it would be quite difficult to "draw a bead" on an attacker, while it's location at the extreme rear of the aircraft would make the cone that it could fire in fairly limited, unless the aircraft was going to go into some pretty wild gyration.
 
As far as fixed tail-cone gun mounts went, the Do 217 was tried with similar arrangement,
but it proved to be of not much utility, & was deleted.

Did the Italians get as far as 'handed' prop rotation as per P-38, P-82, D-H Hornet?

Was the Bf 109Z an independently or co-considered design - contemporary of the Italian jobs?

As far I know the Bf 109Z was something independent respect all Italian efforts (Caproni, Reggiane and Savoia Marchetti) to produce twin fuselage fighters.
For sure Italian designers were fascinated by P-38 while the various German "Zwilling" projects raised up as answer to some wartime operational issues.
 
Would second to archipeppe, the Me 109Z was an independent project to those from Italy, I think, although the reason behind
was the same: To get a fast win with better range and payload quick. The success with the He 111Z probably had triggered,
what actually became a kind of a tick, looking at the number of twin-projects.
BTW, we had another italian twin here : http://www.secretprojects.co.uk/forum/index.php/topic,3465.msg61661.html#msg61661
 
Italian designer started to investigate the twin fuselage configuration long before the WWII, the very first project was the Bestetti-Nardi BN.1 started as research aircraft (technology demonstrator we would say today) rather than an operational machine.


The BN 1 was designed around 1937-39 and it made its maiden flight in July 1940.

There were quite a few twin-fuselage S.55 produced. I think they somewhat predated all the German zwilling projects of WW2. First, the aviation and aerospace community before WW2 was pretty small and fairly close-knit: among other things, Mussolini's Italy funded a very large international conference and even paid the expenses for several aerodynamicists from the US. Second, there was a lot of experimentation, with different configurations (tandem wing, twin fuselage, twin booms, flying wings, airfoil-shaped fuselages [Burnelli], etc) being tried.

"Fighter Lagg in Italian. Experimental aircraft Bestetti BN. 1 Nardi-Italy
In June 1938 the year engineer Pietro Luigi Nardi (Pier Luigi Nardi) presented the results of issledovaniej on determination of optimum aerodynamic aircraft twin-engine scheme according to which this schema is dvuhfûzelâžnyj.
To confirm this theory proposed the construction of a light Nardi engineer četurehmestnogo aircraft capable to fight for supremacy with German sport aircraft.
The decision, made after aviagonok, on the third aircraft fascist meeting (III Avia Raduno del Littorio), in July 1938 year that twin-engine Siebel Si. 104 and single Messerschmitt Bf 108 Taifun "" Italian Caproni Ca 309. machine and Nardi FN. 305 to win.
German superiority can be overcome only with perfect aerodynamics, which should be considered single-SAI-Ambrosini 7 and twin-engined aircraft dvuhfûzelâžnyj Nardi.
Already September 5, 1938 year Aviation Administration (Amministrazione Aeronautica) signed the first contract with a company to manufacture the Bestetti pilot tourist plane BN. 1 (so was called aircraft structures Nardi (Bestetti-Nardi modello 1)) to attend the fourth meeting of the fascist aviation, as well as structural components for conducting static tests. Bestetti firm led the brothers Guido and Angelo Bestetti (Guido e Angelo Bestetti) are successors to one of the pioneers of aviation industry-their father Carlo Bestetti (Carlo Bestetti). Their business was located and Arcore (Arcore) in the region of Brianza (Brianza), famous for its furniture industry. This firm has collaborated with different designers, they designed vyposkaâ light samlety (neaprimer, Bestetti-Colombo C. 3).

"This unusual experimental aircraft designed for flight tests of dvuhfûzelâžnoj designs and "restored" wood
On an airplane design engineer Nardi originally planned to install the engines and then replace Hirth on Alfa Romeo 116. Data engines consisted of Alfa Romeo 115 motor, giraffes are supplied with the compressor. The second major aircraft sobennost′û was that it runs entirely of wood, and the material was used as a supplier of fiber rather than details. Each structural element of the construction is made of "restructured" wood that is oslablenoj and then collected using special glue. In the production process used wood trees growing in Italy, such as the beech, poplar, spruce. In the process of "restoration" due to impregnation of flame retardants they acquired the properties of flame.
in flight the aircraft oddly shaped
The lack of expected engines Alfa Romeo 116 made return to Alfa Romeo 115. In this regard, have changed and the characteristics of the machine: the overall total weight decreased from 2000 up to 1900 kg, with 800 to 650 kg, while empty weight increased from 1200 to 1250 kg. Also changed the estimated characteristics maximum speed (it dropped from 360 up to 350 km/h) and range (from 1500 to 1100 km).
amid traditional twin-engine Ca. 311 "Caproncino" identifies the uniqueness dvuhfûzelâžnogo Bestetti-Nardi BN 1, in which the designer used a "recovered" wood
Changing engines, April 26, 1939 year High Aviation Committee approved a new draft treaty with firm Bestetti, which, however, left unchanged the price of the prototype (362.000 lire) and structural parts for static tests (184.000 lire). Because of this, the aircraft could not be ready by the summer of 1939 year September 30 and Direzione Costruzioni di Milano, which was responsible for the plane, Bestetti sent a report on static tests of experimental aircraft dvuhfûzelâžnogo, who already were ready both pilot cockpit.
BN.1 is the Italian answer to the success of the advanced twin-engine German Siebel Si. 104 on trip to honor III Avia Raduno del Littorio and at the same time serve as a flying ispytat′l′nogo stand for theories of the engineer Pietro Luigi Nardi relatively dvuhfûzelâžnogo twin-engine fighter

The damaged plane crashed to the ground, and spilled from the fuel tanks caught fire, but the plane was rescued thanks to the excellent fire-resistance designs. After 6 months of repair BN 1 running pilot Bonomi (Bonomi) again climbed into the air. Due to weak controllability of aircraft flying qualities appreciate low Bonomi machine: it tried to change the balancing vertical tail and do Note on a special form of compensation of horizontal tail rudders, which was unfortunately one of the problems in the manageability of this prototype
After 50 test flights the aircraft was supposed to be sent to the experimental Center in Guidonii, and in July 1941 year DGCA directs the Commission in Arcore. The Commission, consisting of Captain and Lieutenant, arrived at the airfield of the firm found that the plane had problems with handling. The second Commission arrived 6 months DGCA and rejected the airplane as not corresponding to the requirements of the military: BN. 1 was not designed compensation of horizontal tail (this system was developed some time after the work of the Commission). Dvuhfûzelâžnyj aircraft remained in charge of the company and for some time in 1942-43 years performed flights. After the Armistice, his fate is unknown.
Subsequent projects
Using technology "restored" wood engineer started to design a small hanging Nardi fighter BN 2 capable uncoupled from using special hook with aircraft carrier, he was on board a large portion of the flight.
Static test wing and fuselage BN 2 began in Milan at the end of March 1943 onwards, when the Italian Royal Air Force already have shown interest in the proposal of "composite" aircraft: under the rule of the allies ' chances in the sky Italian "mistelej" were extremely small. Moreover, by this time already fully year Nardi broke off cooperation with the firm Bestetti, dedicated solely to military orders.aerodynamic empennage horizontal compensation. Also required to increase the size of the empennage.
Model BN.2.
Already March 25, 1943 year DGCA invited Reggiane manufacture using experimental technology Nardi, two wing fighter all-wood ones Re. 2005 and Caproni Ca. 331. The aim of this work was to use in the field of military production avtarkičeskih resources and the number of the labour force employed in the furniture industry. June 3, 1942 year DGCA queried in the Reggiane company to determine: whether it is possible to perform Re. 2005 with a fuselage made of wood. Nardi came in November 15, 1942 Reggiane year when alteration of Ca. 331 was abandoned, and the work was focused only on Re. 2005: for these purposes have been allocated 39 engineers and technicians. Inspection of the Reggiane April 26, 1943 year General Aldo Gul′èl′ (Aldo Gugliel) found that the works are in a preliminary phase and are constrained by a number of difficulties and delays. However, it was an interesting result in exploring the possibility of manufacturing dvuhfûzelâžnogo Re. 2005-this is the most modern solution to the question of the establishment of multi-purpose twin-engine fighter. "Reconditioned" wood could be used to create a site ravnopročnyh metal when transferring any existing metal production aircraft on local resources.
Unfortunately, ideas of engineer Nardi in the post-war period are used only in the manufacture of spiral staircases and non-combustible wooden interiors. Dvuhfûzelâžnyj plane appeared only for a short moment in the Italian sky in vain hope to resume winning the competition.

Italian paper projects. Circus of Vahmistrova Señor Bestetti
Introduction: arcore Bestetti Brothers in 1939, they built an unusual double-girder traveling twin-engine plane of entirely new material, developed by engineer Nardi, using wooden structural elements "restructured", IE oslablenoj and then collected with a special glue, wood. Prototype BN 1 became the summer 1940 year fly, but was never considered by the Special Committee of the DGCA.
From the "restructured" wood engineer Nardi has consistently developed the project of a small "reset" fighter 2 BN, i.e. separated in flight of the special "drop" of the aircraft. Wing and fuselage of the aircraft were subjected to static requirements, but beyond this project 2 BN has not gone. A similar fate befell the following draft composite aircraft performed under the same scheme of dvuhfûzelâžnoj BN. 1: BN. 3/4 BN, which will be published extensive excerpts from technical documentation.
The concept of "waste" bomber is as follows: the purpose is called plane-media with a small plane, carrying a large bomb, which should go down with the bomb on the long trajectory, flying to the minimum possible distance from the target. At this distance the plane drop a bomb floating on almost straight-line trajectory, after which the pilot can return.
The aim of this is to cause the inevitable destruction of targets with minimum losses and small scattering of ammunition. It is quite possible that the implementation of the "composite" bomber "dumped" by air to achieve the proposed objectives.
This idea is pointless to exclude a priori, as recognized a priori, without attempting to implement and overcome practical difficulties.
It was suggested that lead to the implementation of the project the composite "drop" bomber and the solution to this problem.
Plan included the establishment of dumping ("Saettante"-"Archer") aircraft of three types, different wing area and rest themselves, separating drop ("Saetta"-"lightning") one of the two types, different wing area.
The proposed project would have
for "Archer":
Special cel′noderevânnuû construction made of "revamped wood capable of maximum strength;
for "Lightning":
mixed in the mostly wooden structure, with the above-mentioned special system for the wings and rear fuselage, the front part of the fuselage, undercarriage and attach motor mount aligning it from chrome-molybdenum tubing and a central cab from an Duralumin.
Project "Archer" has two options:
twin-engine plane (2 × 1350 = 2700 HP) depending on the version has 54 square wing-60 m ².
quad-plane (4 × 1350 = 5400 HP) depending on the 108-acre wing has 120 m ².
"Lightning" was nizkoplanom with the over wing central cabin, managed single-pilot operation, engine with a pusher propeller and landing gear system, allowing them to shift and eat.
"Archer" was vysokoplanom with the fuselage above the wing and looking forward cab, engine, installed in the wing, with driven screws with the two beams plumage and chassis, vacuumed forward fûzelâžnye beams.
Both aircraft had the horizontal tail unit linking the fuselage and tail beams: such plumage can be used during the dive as aerodynamic brakes: large-sized plate, drop down the two sides.
Twin-engined version of the "Archer" had a smaller range and combat load than a quad, but could be used for other military specializations: as a dive bomber, torpedo bomber, strategic reconnaissance and combat aircraft.
Četyrehmotornaâ(4 engines?) version "Archer" very well armed and protected breed range of combat use increased from all points of view. In the same way, without a doubt, the most appropriate is the total bomb load: this fact makes possible its maximum dimensions.
In practice the first version proves to be attractive to smaller, second-for increased loads and range.
Offered as a rational solution to the rapid construction of a pilot version of the twin-engine aircraft for direct military application: it is, in the worst case, would create a powerful vehicle to launch bombs "Lightning" with load up to 1000 kg and with a full range and up to 2500 kg with reduced range, as well as with independent flight combat load up to 2500 kg of bombs or torpedoes at full range.
At the same time, could be held četyrehmotornogo design and manufacture aircraft because designs two airplanes are conceptually identical, it was possible to chart the progress of the twin-engine next model "Archer".

Preparation of composite aircraft "to reset and its performance
Special lifting trolley takes the bomb: she was supposed to be delivered on an inclined rail branch.
"Lightning" is delivered also on above the tracks. Manual winch placed on lifting trolley pulls up to the exact point of grip "Lightning", hooks are attached to rings attached to the bomb and dragged Lanyards: "lightning" is the bomb. Lifting trolley loads the "Zipper" and the bomb at the fixing point, "Archer" and begins to climb. Hooks are attached to "the Archer", rings are suspended to "Lightning" and TURNBUCKLE to tighten. Implemented telephone communication between the pilots ' headphones "Archer" and "Lightning" using removable Sockets and electrical connection engine "lightning" to the battery "Archer".

odnomotornaâ "lightning" with 1000 kg bomb carried in flight two or četyrehmotornym "Archer" 3 bn.
"Composite" aircraft after engine startup is ready for take off. In the cabin, "Archer" raised first pilot and shooter "Archer", and then the pilot "lightning."
After takeoff and arrival at the place of discharge, pilot "Lightning" after proper discussion with the pilot "Archer" descends through a hatch in his plane.
Engine runs "lightning."
Using a pointer and removed a fuse from the pilot of "the Archer" unhooking defined its pilot. Or vice versa, the pilot "lightning" can determine when dumping and implement to remove it. Experience and possible psychological factors will be shown the best opportunity.
The arrow or the pilot "Archer" as necessary steps should release the means of lighting, as well as manage kinofotoapparaturoj.
At an appropriate distance from the goal of the pilot "Zipper" performs a second unlock (reset) and sent in a reverse way.
Individual use "Archer"
The decision to use twin-engined "Archer" as a dive bomber with high-calibre bombs can be considered attractive. Suspension instead of "Lightning" large-calibre bombs could cause a reset capabilities of the plane in a dive bomb weighing 2500 kg or two bombs of 1250 kg, or four on 600 kg.
Use of aircraft as a dive bomber thought possible with applicable, as already mentioned, two special large horizontal brake divergent components made from the rudder, which is part of the tail, two krepâŝego of the fuselage.
Could also be an interesting option of using aircraft as ASW.
In this version, "Archer" were also presented its characteristics corresponding to launch torpedoes: it started flying to the target with an inclination at 30° and at speeds of up to 300 km/h with a pair of torpedoes up to 1250 kg each, then the main part of the trajectory is going with an inclination to 60° when solved the aerodynamic brakes to reduce speed to the maximum permitted, then reducing it to needed 300 km/h on the last stretch before the attack when tilted at 30°.
Replacing part of the combat load with bombs and fuel on the offensive and defensive armament of twin-engined "Archer" could be used for reconnaissance or directly as a bomber.
By reducing the wing surface, take-off, load-haul twin-engine "Archer" with an established offensive weapons could spawn an interesting type of heavy fighter and anti-tank aircraft.
General description of "composite" aircraft: "Archer"-"lightning"
Big mnogomotornyj plane "Archer" possessed a vysokoraspoložennym wing, fuselage dvuhbaločnoj defined on beams with screws driven motors, central cabin installed on the wing, retractable undercarriage and Struts forward hanging under the central part of the wing of a small plane "lightning". This aircraft has low-sited wing with one engine with a pusher propeller, cabin, installed above the wing, and landing skids, located on the tail beams. BTW housed the big bomb.
Between cabin "Archer" and cabin "Zipper" Luke to go through the wing. Among the crew of aircraft mnogomotornogo was also pilot "Zipper" that can go in the cabin of its aircraft.
Management of "Lightning" was performed in the prone position using only the hands.
The device for releasing the pilot in possession of "the Archer", to release "Zipper", carrying a bomb: another device in the cockpit "Lightning" could also produce unlock, acting on the same connection. Similar devices have allowed separate cutaway bomb from "Lightning" on toolpath managed their dive joint.
The structure of the components of the "Archer" and "Lightning"
In accordance with the functional requirements of transportation "Lightning" (1000 kg bombs-twin-engine, with 2500 kg-quad-plane); reset to 2500 kg dive both variants, the dumping of torpedoes in rapid dive or slow down because of the action tormoznâŝego rashodâŝigosâ tail structure of the two options "Archer" is as follows:
mnogodvigatel′nyj from vysokoraspoložennym monoplane wing dormitory; with two fuselages, situated behind the Central Motors at a distance of the diameter of the screws apart rear end plumage and tail wheels, connected to a horizontal plane; Central cabin, located on the wing, partly forward and placed under the wing between the two fuselages, retractable landing gear forward, "lightning" with a very large bomb or bombs: pilot large caliber for better visibility is ahead of the wing, fuselage (and four engine nacelles) are tanks for longer range flights, cabin ends at the trailing edge of the wing, allowing you to freely rotate the screw "Lightning" and install defensive armament (in gondolas for četyrehmotornogo option and in turrets).
The unique design of the "Zippe", in accordance with functional requirements, vyglâdila as follows:
single-seat single-engine, low-wing monoplane with the engine, laden with the wing, with a pusher propeller; landing skids containing plumage tail beams; recumbent seat pilot with a front handlebar controls; the bomb, located between the beams that support the cabin; mounting system connected with clamping system "Archer". From lying to expedite the movement of the pilot's cabin, with a glazed, providing an excellent overview; ATC CAB has protection: bottom at pilot armor and rear in barocentričeskoj zone is located behind the fuel tank, the tank engine is installed; screw push to avoid impact on structural elements of "the Archer", rotating between beams "Lightning"; with a big sweep, ottâgivaûŝej ago SAH and adds stability, with dimensions that are not ground chassis "Archer", and cross the fuselage.
Swept wing with a solid construction made the decompression shift by the end of the elastic axis of the wing to prevent aerodynamic vibration excitation. Secure cab liaised with cabin "Archer".
General information on projected features
Implementation of the "composite" bomber "Archer" was meant primarily to prove the opportunity and advantage of the system before its destruction when it reaches the target. And no matter at what speed, "Archer," that would be achieved-at 450 or 500 km/h, if the maximum speed of the "Lightning" was supposed to reach 900, and normal-350 or 370 km/h; the identical value had a rate of climb and ceiling. It's all had a relative value, when it started designing, requiring high-performance engines, and barring engines, available at aličii. Flight range, easily extendable by changing the wing surface was relatively important in the presence of tanks, allowing to reach high values. In this case, valuable guidance obtained from blowdown pipe aèrodimaničeskoj results were not yet available and projected characteristics were common and indicative values, formulas and charts, being tentative and approximate estimates.

Hi! BN-2.
Is this a carrier fighter? Sorry for off topic.

If by 'carrier fighter' you mean a shipboard naval aircraft, then no. The BN-2 was a 'composite' or 'parasite' fighter concept to be carried by a larger aircraft for most of its mission.

Hi 'kite... yes the mock-up had the cockpit on the left. The drawings configuration is the same of the windtunnel model. More on ISP.
