Hi,

Design definition study of a lift/cruise fan technology V/STOL airplane: Summary - NASA Technical Reports Server (NTRS)

A two-engine three-fan V/STOL airplane was designed to fulfill naval operational requirements. A multimission airplane was developed from study of specific point designs. Based on the multimission concept, airplanes were designed to demonstrate and develop the technology and operational...

Nice drawing, don't *think* I've seen this design except as a tiny thumbnail before.

Now that's a Flying Hoover if there ever was one.

Interesting concept.

My dear Overscan,

I think this aircraft was the competitor for Vought V.530.

 

[Stargazer]

Yes, of course, all "Type A" projects.

This seems to be the same design ("Boeing VSTOL" from US VTOL Projects topic)

I just posted the link provided by Google!? Sorry if I have done anything wrong!

The site in question has thousands of issues of hundreds of different magazines and journals on every imaginable topic, none of which would presumably appreciate being made freely available to non-subscribers.


If you visit www.aiaa.org you will find that you are supposed to pay for access.


Google indexing something does automatically not make it legal, you should use your own judgement.

Yes it is a great drawing and an interesting design. Although it has the 'Filing Date' of the 24 May, 1979 on it! Isn't this past the USN's Type A program?

Yes I think you are correct PaulMM!!
Going by the multiple drawings you posted before this, I'm assuming its the SA (Surface Attack) LCFA-131..........................I think

Nice find!!!

So are the three 3-view drawings (Fig 10, 11 & 13) Boeing designs??

Often companies gather these up at the end of the relevant project and submit them en masse.

Yes, Boeing used it for comparison:

...In 1974, Navy interest in V/STOL caused the studies to be redirected toward what is now the type A V/STOL. At Boeing, the first of these studies resulted in a three-fan, two engine design with an optional third engine for transport missions. The power to land vertically after failure of one engine was achieved by a contingency rating. Subsequently, the Navy asked that design without a contingency rating be considered. This led to a three-fan, four-engine airplane...
...Recently, a review was undertaken to see if it was possible to design an airplane that is simpler than one with the threefan, four-engine, interconnected V/STOL system. The objectives were all to be accomplished on one airplane; in practice they were taken in stages. They are: 1) eliminate or minimize the interconnect; 2) reduce the number of fans to 2; and 3) reduce the number of engines to 2...
...In the search for simplicity, a variety of airplanes were designed. One group had two fans driven by two or four engines with bleed for pitch reaction control. Another group used individual turbofans; two- and four-engine airplanes were considered...

Very nice - Thx for sharing!

...I would appriciate if someone can provide a more detailed inboard profile + cross sections of the one posted below.

Nice one, VTOLicious!

 

[jsport]

ditto that, great work VTOLicious!

 

[VTOLicious]

Nice one, VTOLicious!... ditto that, great work VTOLicious!

Thx! ...still work in progress. Modelling adjustable lift fan louvers is tricky. Another concern is the main landing gear. The gear folds into the outer part of the wing, which is foldable by itself! Maybe i will cheat here and make the landing gear retract into the inner part of the wing.

Btw, any suggestions regarding positioning of markings, antennas, lighting and other details that make the model look more realistic?

Great work my dears,

and after 1041-133 & 1041-134,here is the Boeing Model 1041-135;

I´ve removed the pic from my previous post, but here is another one of the enhanced 3D-model with moveable lift fan-louvers, flaps and engine nacelles - Enjoy!
