A couple of designs from JP4 magazine

Air Metal AM-C 111 (Germany). First flight was scheduled for 1977. Estimated production: 500 aircraft from 1977 to 1986. Turkey and Malaisya were very interested in the project.

Versions: Passenger (24 seats) , VIP (13 seats), Cargo (up to 3000 kg), Medevac, military transport, photoplanimetric, navigation trainer and geophysic research

Powerplant: UACL PT6A-45

SAAB MULAS Transporter.

Versions: Passenger (19 seats), Cargo (up to 2000 kg), Medevac, SAR, geophysic research
, agricutural and firebomber.

Powerplant: Continental TIARA T6-320 (4 engined version) or UACL PT6A-41 (twin engined version)


SAAB considered that CASA 212 was no rival for its design so it had a bright future.

Similar in layout and time frame :

Pilatus launched a sales subsidiary with the munich, german based Poligrat
development in 1973, to sell a twin-engined STOL transport, called the
Master Porter PD-01, which was expected to enter the market in 1976
and would have been sold as completet aircraft or as a kit for local assembly.

Very interesting projects, the Pilatus Master Porter is similar to the CASA C-212 Aviocar while the Air Metal AM-C 111 looks close to the Let 410/610 series. It is my personal opinion, of course

Hi pometablava!

This is a Russian-built aircraft, the Myasishchyev MM-1 which was based on the Air-Metal AM-C 111.
It was to have flown some time after SEPT 1993 (I think), but I haven't any further information.

STOL transports weren't just interesting for commercial use, as can be seen by
this project, the Potez 870, which was intended as an army cooperation a/c,
with quite an impressive ground attack capability.
The drawing is , I think from "Planeurs et Avions", Christian Castello, I'm not
sure, but the copy was among other copies from that book ... ::)

Two other french projects from the early sixties, roughly comparable to the Shorts
Skyvan :
The Latécoère 850 to 853 series (shown the 851) with two Astazou I or II engines,
with a power of 469 to 562 hp and a MTOW of about 5500 kg and a take-off run
of around 400m.
and
the Latécoère 880 to 882 series with two Astazou II, MTOW 5300kg and a 430m
take-off run, kind of a refined 850.
(Data from J.C.Cuny " Latécoère-Les Avions et Hydravions").

Interesting how all the different aircraft start to look the same - I guess the same problem often ends up with the same solution. Another to add to the list (and this one made it into service) was the GAF N-22/N-24 Nomad:

Accommodation : 1-2 crew + 12-13 passengers Dimensions Span : 16.52m (54'1ft) Length : 12.56m (41'3ft) Height : 5.52m (18'2ft) Weight empty : 2,150kg (4,741lb) max : 3,855kg (8,500lb) Power Plant : 2x 400shp Allison 250-B17B turboprops Performance : max speed : 311km/h (193mph) max climb : 1,460ft/min (742m/sec) ceiling : 21,000ft (6,400m) range : 1,074km (668miles)

It was operated in both civilian and military roles by a couple of countries.






Regards,

Greg

On Aviation Magazine Number 516, 15 June 1969 I have seen pics from a model of the SOCATA Sherpa. The model depicted it is a clone of the IAI Arava :eek:

Are both types related?

Arava's first flight was on November 27th 1969

WHAT ? WHERE ?? WHEN ?? :eek:
More infos, please, especially as SOCATA includes Morane Saulnier !
The only french Arava "clone" I know, is the SIPA 270 Présence,
the project first shown to the public in 1960, so maybe the Arava
is in fact a clone of the SIPA !

“Turboprop DC-3 replacement is expected to be in prototype form by the end of the year. "Typhon" is up to 26-passenger third-level airliner from Aero Southwest Corp., Santa Maria, Calif.

Would the propsed but never-built CV-10 version of the Bronco fit in this category? I'll try and post some info when I get home.

And here a type, which, although in its basic form not renowned for STOL capabilities,
should be improved by Dart 10-1 engines, improved high lift devices, spoilers and a
new brake system to achieve better short field performance for the military version
of the Handley Page Herald 500, the HP.131 :
(from Flying Review 6/65, profile only)

Hi hesham!

Had we included the Ahrens AR-404 yet? Only two were ever built, and it was thought that it might replace the C-2 Greyhound in the Carrier On-Board Delivery role.

Slightly off-topic, I know ... but as Chuck mentioned, that the
AR 404 was proposed as a Greyhound replacement, I thought,
it might be interessting, what I found in Air & Cosmos '68 :
Did you know, that a british twin engined civil STOL aircraft
anded on and took off again from a british carrier ?
A BN-2 Islander landed on May 26th 1968 on the HMS Hermes
and was launched again, without the use of arresting gear and
catapult. Ok, compared to the Hercules carrier trials, not really
a great achievement .... ;D

And here comes a candidate from Iran - the AII (Aviation Industries of Iran) AVA-404, planned with two Walter M 601E turboprops. Is there somebody who needs the estimated dimensions, weights and performances? Next Wednesday I have to give back the borrowed JAWA 2001-2002 ...

Just found in RAF Flying Review 3/1962 : The Ryan BLC.7 , mainly intended
as a STOL executive aircraft, but also proposed for military use.
It would have been powered by two Allison T63 turboprops and have used
boundary layer control.

Hmm, I'd consider the Allison T63 (Allison 250) to be a bit on the small side for only two to be used with that size airframe, I'd think that the T74 (PT6A) or T76 (TPE331) would be better choices.

Within the "harvest" of my visit to the States Library :
The Wagner W-18, designed around 1963, with the maiden
flight expected for 1965, was intended as a DC-3 replacement.
A new kind of boundary layer control was envisaged, with span-
wise ducts in the very small high-aspect-ratio wings. These
ducts would have been fed with air from an APU in the tail and
fuel should be burned in it, to accelerate the airflow.

Drawing from Flight International, May 1964
