Thanks hesham .. the A.34 has now been added.
Theoretical and Speculative Projects / Air-Launched Switchblade UAV?

There's a complex story behind this notion but I'll ignore it.

I recently noticed that the Northrop Switchblade's concept model has somethings parallel to the Lockheed Minion - variable-sweep wings, top-mounted intake...well, I guess that's as far as it goes, really.

But still, with that lack of vertical tail, wouldn't it be fairly easy to give it modifications for air launch? Was Northrop maybe just bringing up the manned version to fool us into thinking no drones of it existed? And how often does that actually happen?

EDIT: Inspecting the total width more, it seems unlikely this would make a decent "reusable cruise missile". But I'm still curious how often corporations make manned aircraft models to hide the fact they're making unmanned ones.

LeO-32 was a night bomber prototype to a 1924 specification.
The 1926 LeO-122 mentioned by Boogie led to the LeO-20 series.

Frédriksen - International warbirds: an illustrated guide to world military aircraft, p.199

My dear Apophenia,

here is the page which spoke about LeO-32,from the same source,and in TU,there is unknown
LeO Project for BN.3,a three seat night bomber,with 5 machine-guns and 950 kg bombs and
a 600 km range,and maybe that's it,via my dear Tophe.

Un-solved mystery to this days,in its designation number ?.

I don't know if this aircraft was from author's imagination or what ?.

'Cabrillo Corporation'

Oregon (II)
Armed Merchant Ship (Converted 1960s cargo liner)
Length: 560ft (171m)
Beam: 75ft (23m)
11,585 tons
Propulsion: MHD Engines
Speed: 50 knots(+)
Armament: 1 x 120mm Cannon (Bow mount) 3 x 20mm Gatling cannon 4 x Exocet Missiles (Concealed in forward hold) 2 x Land Attack Missiles (Russian, type not specified.) 2 x 21 inch Torpedo Tubes (Bow), Machine Guns. Note: All weapons are concealed.
2 x Minisubs
1 x Helicopter
Note: Conversion was done at a Russian shipyard, but paid for by US Govt 'Black Budget' money. The below-water hull has been heavily modified to allow safe transit at high speeds. Mercenary ship, owned by the 'Cabrillo Corporation'. Registered in Iran (Carries flags for every maritime nation.) Performs intelligence gathering on behalf of the United States Government and other related work on behalf of friendly nations. This is the replacement for the ship of the same name that appeared in 'Flood Tide' (1997)

Orbital Ocean Corporation

Kalinga (ex-?)
Nilgiri Class Frigate
Details as per the real ships

Maurya (ex-?)
Nilgiri Class Frigate
Details as per the real ships

Note: Both ships are ex-Indian Navy, the authors do not specify which former Indian Navy Niligri Class Frigates they were.

Plot summary: A mission to recover stolen Russian nerve gas leads to the discovery of an ancient conspiracy.

Note (Spoilers): For the latest in the 'Oregon Files' series the authors mix together one of the possible solutions to the MH370 disappearance with ideas taken from the film 'Airport'77' and a tale from the fringe about a secret order founded by the legendary Indian Emperor Ashoka to guard the worlds knowledge lest it be misused.

Rather ironically the tale actually originated with a 1920s pulp writer named Talbot Mundy, who'se 1923 novel 'The Nine Unknown' deals with an attempt by a multi-racial band of adventurers to steal from a mysterious organization that controls the worlds economy in secret. (The novel can be read at the Australian Project Gutenberg website. (Link)) Their re-appearance in this 21st Century pulpy story can be seen as a kind of 'coming home'.
There is also a technothriller by author Bart Davis from the early 1980s, I think it is called 'Takeover'. The plotline involves a coup attempt by hardliners against a reformist leader. Only to find him protected by a newly created AI that's tied in to the entire Russian economy/state.

I'm guessing that he had heard early reports on OGAS.

The model is made out of wood and metal by the skilled model makers in the Philippines. I fear my own skills do not run to such things. They can produce some astonishing stuff if you provide schematics and advice on markings etc. I source mine through Aviation Retail Direct in London who are really helpful.
Project cybersyn. Died with Allende in september 1973. Same goal as the Soviet one: a centralized, planned economy.
Propulsion / Re: Jet Engine Assisted Takeoff - Examples
« Last post by charleybarley on September 22, 2018, 06:03:22 pm »
However, one question remains: How would you by definition separate the aircraft with mixed propulsion (example: Ryan Fireball) from the airplanes with auxiliary engines (example: C-123J), or does both mean the same thing?
The following statement will cause confusion and worse because your definition is different to mine.  The Skyhawk, Shackleton Mk3 and Gannet had thrust augmentation.
It's better if I say:
The thrust on the Skyhawk was insufficient to get it off the deck so it was augmented with a steam catapult.

I would not classify a catapult as thrust augmentation. To me (admittedly not being a native English speaker) thrust augmentation implies some sort of an additional propulsive system on board an aircraft (even if it may be separated after use), whereas a surface based launch aid such as a catapult in my view falls into a larger class of acceleration augmentation, which includes off board devices as well.


Thrust is what urges the plane forwards and augmentation just means making something bigger. The catapult does exactly that, gives more urge, augments the engine thrust.  Traditionally, for gas turbine engines the term has been used for things within the engine that do that. Therein lies the problem. Using just two words, thrust augmentation, because we all like trying to classify things, doesn't work well. You have pointed this out by using a few extra words to make a better job of communicating what you are actually thinking.

Here's an example of trying to use a definition or classification which touches on Chris' turboramjet 'can o' worms'. Kelly Johnson (in his autobiography Kelly More Than My Share of It All) said the J58 'flew as a ramjet". If he had left it at that, as do most other writers on this subject, we would have been left guessing. We would have comments like 'what definition for ramjet is he using?' 'He must mean it is because of this or because of that' It's up to us to guess or assume. The good news is, unlike other writers, he does go on to tell us why he used the term. 'With no machinery obstructing the airflow...' And it turns out to be incorrect as shown in published information, such as YF12 pilots manual, etc.
