Lockheed ASTOVL, JAST, JSF projects

Unfortunately, Skunk Works destroyed the documentation for the classified GhostHawk concept after the DARPA-sponsored program terminated. When the US Marine Corps and US Air Force launched the Joint Advanced Strike Technology (JAST) program a few years later, Skunk Works was forced design a whole new airframe.

SO, anytime a DARPA funded program of a new classified tech demonstrator gets concluded, all the related work and materials go *poof*?
Both the taxpayer and the Aerospace fan in me are pretty appalled by this.

From a technological evolution point of view I find this pretty horrific as well. Patent b.s. aside, no man makes great technological strides without standing on the shoulders of those before him. We cant just go around wiping out the shoulders..... :'(

Yeah that does seem pretty @#$%%!! stupid given that you just KNOW someone is going to come by later and try that idea again because they don't know that it's a proven failure.

Well, you have to consider that this design study was just for a stealthy STOVL fighter. It was designed before the JSF requirements were ever released, IIRC. I also believe it was the Navy requirement which forced them to go from a canard to a conventional tail when they began designing for the JSF program.

I think Dan was saying that the picture shown is not an accurate depiction of the Ghost Hawk.

Oh, OK, thanks!

I plead ignorance. I just read it and thought I'd show a bit of interest - Thanks for the correction.
 
How did the Boeing JSF design (X-32) get assigned the same X-plane number as the Lockheed JAST/ASTOVL design? Or was the Lockheed "X-32" a company designation?
 
Can anybody cite the rules which DARPA operates by that gives them the authority to have all materials for a project destroyed? Surely there is some incredible red tape somewhere in our bureaucracy that prohibits them from doing this?
 
This is just pondering on my part, but does the name "GhostHawk" imply that it was a visual stealth platform and that is why DARPA requested Skunk Works destroy the documentation for said classified program?

Inventing the Joint Strike Fighter
Dr. Paul Bevilaqua, Lockheed Martin Skunk Works

Thank you!

However, every time the document pretends the JSF is a viable A-10 replacement I throw up just a little bit in my mouth.... ;D
 
XLNT, most interesting, I see from page 36,
that the JSF is referred to as the 'X-35 Musketeer',
that's a new one on me...


cheers,
Robin.
 
Musketeer - as in 'one for all and all for one'.

Paul Bevilaqua was using this name in 2003 when he taught on a V/STOL design course I was on - I think it was his preferred name for the aircraft, and maybe used informally inside LM at the time.
 
Heh. Was the "What you see, is what you get!" slide taking a shot at the looks of the Boeing X-32?
 
The X-32 confusion: The designation X-32 was assigned to the DARPA CALF program before JSF was in being. I don't think DARPA had any hope of being able to flight test more than one concept, so the plan was to test Large Scale Powered Model (LSPM) versions of three designs (they started with Lockheed and Macs, then Boeing came in) and then downselect. In this stage, I believe that the three designs were known as Boeing X-32A, Lockheed X-32B and Macs X-32C (alphabetical order). Boeing and Lockheed tested LSPMs but the Macs gas-driven liftfan version was never tested, since Macs abandoned the GDLF before that happened.

The X-32 designation was continued into the JSF program and went to Boeing (alpha order again). In the meantime, X-33 and X-34 had been assigned to NASA, so LockMart's design became X-35... and as we all know the SDD aircraft became F-35 because of a misunderstanding in a press conference.

I thought exactly the same thing when I reached that page... Amazing we never heard it before! Another "lost" company name that the armed forces did not want...

Makes a lot of sense, actually!

I can't conceive of an employee, be it an isolated engineer or a PR guy, using a name like that just because he likes it, without there being some company endorsement for it at some point...

Again, my thoughts exactly... sort of: "Look, ugly failed and handsome won!"

Fascinating and quite logical indeed. Thanks for clarifying this annoying non-sequential allocation.

The aircraft Lockheed proposed for the Common Affordable Lightweight Fighter was called Configuration 100. The delta-canard design had twin vertical tails and a pronounced forebody chine. Trade studies were conducted to refine the design in late 1993. Configuration 140 emerged as a baseline used to build a 92 percent scale powered model. The requirements for testing the model in the NASA Ames 80- by 120-foot wind tunnel called for a safety factor of five times the normal design loads. To meet these requirements, the model was fabricated from sheets of 1/4-inch steel plate. The result, which weighed almost 50,000 pounds, incorporated an F100 engine and a lift fan built from the first stage of an F119 engine. The model was used to test the interaction of the airflow from lift fan and the aft nozzle. The data gathered from this these tests helped Lockheed win the Concept Development phase of the X-35 program.

Matej, that's X-35, not X-32!
 
that's true - that should become X-32. read the topic carefully, LowObservable had a remarks on this
 
Why do you think that it was not Lockheed X-32 (at the time when the photo was taken)? Lowobservable wrote:

Captions on the AILS photos are (the first is related to the photo that I posted):

AC95-0154-333
Photographer: Dominic Hart
Date: 02/23/96
CALF/JAST X-32 test program: the LSPM (Large Scale Powered Model), Lockheed's concept for a tri-service aircraft (Air Force, Navy, Marines) CALF (Common Affordable Lightweight Fighter) as part of the Department of Defense's Joint Advanced Strike Technology (JAST) is being tested in the 80x120ft w.t. test-930 with rear horizontal stabilizer

Another photo:

Date: 10/19/95
JAST (Joint Advanced Strike Technology) X-32 Test Program: Lockheed ASTOVL / CALF X-32, N-246 Test #930 arrival, unloading and test prep.

So what?
 
Don't be upset, Matej. I first thought it was a typo, not thinking of relating the picture to the info that had been discussed further up.
Also, I kind of figured that this early set of designations was strictly theoretical and only given in early papers, never applied officially at all. Was I wrong?
At any rate, if they were used, labeling the picture as plain "X-32" is insufficient, since it should be "X-32B", right? ;-)
 
Names that were under consideration for the F-35 included Lightning II, Spitfire II, Black Mamba, and Piasa. Some of the names that were submitted by US Armed Services and Allies included Mustang II, Scorpion, Phantom III, and Skyruler. Fury was a favorite but rejected because of a possible trademark violation dispute with Chrysler Corporation and its Plymouth Fury automobile manufactured from 1956-1978.

Hmm, the JAST reminds me rather strongly of the new J-20 design. I suspect the resemblance runs the other way.

Strange, because they USAF still used names like Lancer and Spirit for the B-1 and B-2, both Chrysler Corp names :)
 
Seriously...by that rationale Plymouth should have been sued by North American, which in turn should have been sued by Hawker (and who knows whom else used the name). I'm not questioning the fact that this actually happened, but this is ridiculous...
Frickin' lawyers... ::)

One of the rationales behind calling the F-16 the "Fighting Falcon" was that Dassault had already copyrighted the name "Falcon" for their bizjet.
