Hi,

who know this concept ?.

Interesting, thanks Hesham.

From the text, this model just seems to be testing the pivoting forebody as a possible way around the shortcomings of the X-13 Vertijet. The tailed-delta appears to have won out over the 'least mod' version of the F-16.

The 3-view (Fig.3) on page 19 shows more details of the airframe, reaction controls, etc. Attached is a more compact, reorganized version of that Figure.

BTW, for anyone interested in the LTV XC-142A, there's a drawing of the 'free flight' wind tunnel testing of that V/STOL aircraft on page 25.

Right Apophenia , it seems that this model haves nothing
to do with the F-16...

There was also F-18like model as well. I am sure that I posted the photo somewhere on the forum, but cant find currently where.

Looks like a GD take on the Grumman "Nutcracker" concept.

The model used in the investigation was a modified version of an existing research model generally representative of current fighter configurations.

They just took spare model to make the tests.

The Convair Model 49 is reborn ! ;D

Well, Matej is right, but I couldn't find it, too.
Here it's again, from Aviation Week 1975, the F-16 was used
as basis, as well as the F-17.

Thanks Jens. Interesting to see the different pivot points chosen for the two models.

The same F-16 photos were reproduced in the NASA pdf but your AW&ST versions are of much better quality.

It was just a two page article, here's the other page:
(we already had it here : http://www.secretprojects.co.uk/forum/index.php/topic,2140.15.html,
"F-16" and "tailsitter" were the "passwords" )

Would they be designed as an ejection module rather than seat ??

Sorry, can't remember which production aircraft had this facility-- Well, except for the Valkyrie, with its pods.....

XF-103 too

Yeah, but it never flew, so it doesn't count!!

Re: Самолеты F-16 и F-17 с вертикальным взлетом и посадкой и наклоном кабины.

Привет,

а также, согласно отчетам НАСА, речь идет об истребителях F-16 и F-18;

Those would all need pretty substantial power upgrades to be able to take off vertically. Even with the F100 engine. The F-16/79 doesn't have the power at all, even in afterburner.

I'll assume for simplicity that the pivoting-cockpit gear raised the empty weight to that of the F-16C. That means 18,900lbs empty. Let's assume that the mission is pure air defense. 2x AIM-9 and 2x AMRAAM, call it 1100lbs weapon load for 20,000lbs VTOL weight. Half a tank of fuel (3500lbs) puts us up to 23,500lbs takeoff weight, pilot and parachute adds another ~375 to bring us up to a total of 23,875lbs. The F100-PW-200 made 23,830lbs thrust in full afterburner, but had serious reliability issues. The actually reliable PW-220 made 23,770 and wasn't available until 1984.

Does anyone have access to the video of this thing in the wind tunnel? This is from the initial pdf at the start of this thread
