Again, Hesham, no NASA here at all.

Hi,

Hi,

NASA twin engined fighter of 1987.
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19870012440_1987012440.pdf

these are, again, not 'engines', but model supports

 

[hesham]

Hi,

look like XB-70.

Hi,

a strange NASA model for arrow shape aircraft.

Hi,

here is unknown aircraft to me,it was not X-2,because it had a mid wing,
and did't look like the Douglas D-558-2,because it had a low rear wing.

Hi,

a business aircraft from NASA;

Hi,

here is NASA Sketch of rotor/wing planforms and table of properties.

Hi,

some turboprop engined projects;

[hesham]

Hi,

the three models which display here are look like XB-70.
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19930090231_1993090231.pdf

 

[Stargazer]

Picture L-58-256 especially reminds me of the SR-75/Blackstar carrier aircraft that has been hypothesized and allegedly observed according to AW&ST...

 

[hesham]

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.

Here is the NASA EEA (Energy Effcient Aircraft).

Hi,

http://www.nianet.org/workshops/docs/QA/presentations/ADS/Guynn.pdf

Uhm this link is broken or not available anymore, anyone have another "version" ? (I'm trying to figure out WHY there is a "pizza-delivery" UAV )

Thanks

Randy

When NASA still was NACA, this concept for a prop driven aircraft was drawn, where
air and fuel would be ducted through hollow prop blades and ignited in combustion
chambers at the prop tips. The mixture would have been compressed by the centrifugal
forces and it was thought to be more economical, than conventional engines.
A tractor design was drawn, too, where air would pass through the hollow hub.
To me, the idea seems to be too similar to tip jet driven helicopters, which mostly
weren't economical at all, but maybe the higher number of revolutions, compared to a
rotor, would have done the trick ?
(from Aviation February 1946)

and very NOISY...

[Stargazer]

Nice! I could be wrong, but the "Emergency Car" and all related pictures have a Hiller feel to them... artwork, lettering, fuselage design.

You are right my dear Stargazer,

it look like a Hiller design.

Here is the NASA spanloader model.

[hesham]

Hi,

here is a group of NASA aircraft,the second may be a fighter
derivative from NAA X-15.

Nice and interesting projects, especially Vstol civil aircraft concepts ! B)

[flateric]

In fact it doesnt change the fact that it was in-house and not contractor's study

 

[Stargazer]

Another unknown (to me) NASA project, the M-4 lifting body:

Two pictures can be downloaded here:

Watching the MV-22 land at AHS was awesome. Watching it leave was just as spectacular.

Hi,

[Tophe]

Interesting "Twin or Triple fuselage large airplanes", dated 2002 it seems according to your link. But is this NASA or Belgium research?
Your topic http://www.secretprojects.co.uk/forum/index.php/topic,13847.0.html covers this Twin-Antonov, so it seems an overview of World possibilities, OK.

NASA Wind tunnel model used to test the characteristics of supercritical wings.

Top. Side and top views of the model

Second. Closeup of the wing design

Third. View of model in 'flight' configuration

Fourth. View of model in 'landing' configuration

Bottom. Dimensions of the model (I've not been able to locate the scale of the model, so if anyone can find out?)

 

[hesham]

I sent that before Graham;

[Graham1973]

Perhaps we should merge the topics and eliminate the duplication.

 

[Antonio]

My suggestion is we should delete the present topic to avoid duplication. I can't see the utility of merging because we have just a duplication not a complementary topic/post.

Nevertheless I wait for more moderator feedback.

Four engined jet-powered transport fitted with thrust reversers.

More images of the mystery four engined jet-powered transport and the thrust reverser designs being tested on it.

[Graham1973]

Graham, you posted the same pic twice. Did you mean for four different pics to be posted, or were there only three?

It was meant to be four different pictures. I've corrected the mistake.

Now, another of those generic test models, this one looks more like a 'modern' jet airliner rather than the XC-99 like model in my earlier posts. This one was used to test aerodynamic characteristics of a 'typical' jet airliner at simulated speeds between Mach 0.4 to 1.2.
