Hi,

We can speak about NASA projects which was never built.

During the end of 1970s,NASA had launched a program for Energy Efficient Aircraft,
a joint NASA/US industry research and development project to reduce by 50 per cent
the fuel consumption of future generation civil transport aircraft,the project was
for airliner aircraft powered by four rear mounted engines (look like Vickers VC-10),
I have a picture for the model but I can't send it.
 
From Aviation Week October 1974, a photo of a model for an
energy efficient airliner, using composites, supercritical aerodynamics,
laminar flow control and fuselage boundary layer injection. Fuel savings
of about 55 % were expected ( against the 1974 standard) !
I think, this number already shows, that these concepts shouldn't be
regarded as "projects", but more as research for principles and techniques.

Good find my dear Jemiba,

and the picture for the model which I have,was look like Vickers VC-10
with four rear mounted engines.
 
Hi,

the NASA high-speed tilt-rotor X-wing project,it is new for me.

I will just make sure we don't miss the X-33

A subscale model (1/3) of a Single Stage To Orbit (SSTO) unmaned shuttle called the Venture Star.

The X-33 was designed to demonstrate several technologies that will enable low cost to orbit possible:
- aerospike engine (success)
- metallic thermal protection system (success)
- all composite fuel tank (failure)

After the good advice of the engineers, the program managers kept on with the composite tanks which failed in two consecutive test. By this time, the engineers have come up with a all aluminium design that was even lighter but did not have a chance to implement it.
A well known NASA official spoke to the Congress that is not worth to proceed unless all tree technologies can be tested. The importance of the composite tanks was due to the large civilian involvement in their fabrication.

An excellent article on the cancellation is here:

I found, flaterich had also a tread going on the X-33 here

Many thanks for the link Hesham, what I really love from that document it's the Bell L-39 sweep wing research aircraft. I've never seen it before in flight and looks wonderful.
 
Great finding Hesham! :)

Could you please post the source?

Thanks in advance

anther two NASA projects,each six jet engined aircraft,but one
was subsonic and the other was supersonic.

The wind tunnel shapes include Apollo shapes (some of the famous "with vanes" design and some with the escape tower too) as well as reusable booster stages (the blunt cylinders with a flare at the bottom). So they are just some shapes that have been tested in the hypersonic wind tunnel for a wide variety of programs.

The Boeing plane looks like a Mini-Valkyrie.

Cruise and acceleration are conflicting design requirements. Thus it doesn't make sense to make a cruiser launch small craft or a booster that cruises.

It looks like and, actually, *it is* a Boeing's submission in a NASA study for SST technology applied for 500-mile radius supersonic cruise fighter for European air battle area.

Hi,

here is,a distributed propulsion with many engines applied to a
conventional trasnport aircraft,notice the circle tail,and the
Kuchemann's jet-wing concept.

Tried to open the link, and failed miserably.

Does anyone have more info on the "Pulsed Ejector Thrust Augmentor" and the "Multi-Gas Generator Fan" concepts ?
