Rockwell pre-ATF and ATF studies

Thanks. I didn't know that little trick. (I don't spend much time at sites like this. A lot of my on-line time is spent doing art searches.) I agree that with a way to get to the original entry, moving and splitting is not a problem.
 
Hi,


here is the Rockwell D619-3A ATS advanced fighter concept,who can collect the pieces.

New Concepts in Composite Material Landing Gear for Military Aircraft. Volume I. Technical Discussion.

Final rept. Apr 76-Feb 78

Thank you my dear Flateric,


and here is the Rockwell D647-1 & D647-2 supersonic fighter projects,they called it BIAS,
developed from D575,a compromised solution for joint aircraft.

SUPERSONIC CRUISE/TRANSONIC MANEUVER WING SECTION DEVELOPMENT STUDY

Nice find my dear Paul.
 
Advanced Design Composite Aircraft (Rockwell North American)

It's a trade design study comparing the all metal version against the composite design. Below is the composite design and the document contains the metal version and the inboard profiles of both which need stitching together. Notice the rear firing A2A missiles in the rear bay.

Here are more images from the same document. The image I pieced together I just tried to align the side view, not the top view. I could do each better at a later date when I have time, but this is alright for now.

I was given this drawing from a friend who worked at Rockwell in the middle of the HiMAT, AMSA, and pre-ATF years.
According to him, this was the preferred configuration before Raymer convinced management to use his.
It's obviously HiMAT derived, which was a selling point, but my friend told me that it was pretty obvious there was no way to cram meaningful quantities of fuel in it, it was a non-starter.
Pictures of this concept can be seen in pages 1 and 2 of this thread.

[Model appears to be D670-13A-2C -Admin]

Note:image size reduced from original, i have a better copy HiMat Fighter 1979 Ed McGachon_50%.jpg

Its from 1979 - this is well before ATF concept formulation, so there was no consensus of what ATF might be. Some of the CF studies were lightweight fighters.
 
Quick tidy up - will do better later on :)

Program is called TIGAR - Tactical Interceptor, Ground Attack & Reconnaissance.

Rockwell "Low Cost Fighter" model. Pretty close in overall configuration (no 2D vectoring, and nose is different).

This has to be one of the most nightmarish ammo feeds ever designed.
 
Yeah, i'm not familiar with a whole lot of ammo feed systems but that seems a pain in the butt to work on. I wonder if the small overall dimensions of the fuselage forced the designers into this awkward layout.

Its half-brother, perhaps. It dates from before the Su-27 configuration was known, but the Su-27 had some similarity to the Rockwell FX which is the "father" of this design.

I love the Rockwell F/X. If we're talking Flanker similarity however. . .how .bout this Vought design:

Frank - I'm not sure posting it will make your day, but obviously that's what you are looking for.
This is '78 Rockwell 'high-altitude supersonic penetrator' air-to ground concept, pre-ATF in a way it was proposed then (with emphasis on ATG missions). To my sorrow that's the best quality - and all - I have on this.

A supersonic a-10! That’s an impressive concept
 
The esrly ATF work flows straight from AFTI and LCF studies.

d525-106-afti-supercruiser-jpg.100611



I did some digging, and I found a great drawing, dated 1-23-75 entitled "D525-106, AFTI-Air Combat Fighter-SuperLight-Single YJ101 Engine". I think there was a whole series of drawings I did that linked the AFTI work (I probably did 20+ AFTI concepts) to the Lightweight Fighter (I think I did at least 15+ LWF concepts). This design is really neat looking, and would appear modern today. It is zoomier than the model you have (I don't think we made models of the really far-out designs)

Then there's the M = 1.6 NASA/Rockwell Supercruiser referred to in https://apps.dtic.mil/sti/pdfs/ADA110686.pdf NASA-Rockwell Supercruiser.png

Which is based on the Model D575 as seen in this 1975 NASA/Rockwell Study "Design And Analysis Of A Supersonic Penetration/Maneuvering Fighter"

Design and analysis of a supersonic penetration/maneuvering fighter - NASA Technical Reports Server (NTRS)

The design of three candidate air combat fighters which would cruise effectively at freestream Mach numbers of 1.6, 2.0, and 2.5 while maintaining good transonic maneuvering capability, is considered. These fighters were designed to deliver aerodynamically controlled dogfight missiles at the...

A look back....Rockwell Highly Maneuverable Aircraft Technology

During the 1970’s the name of the fighter game was maneuverability. In 1975, the Air Force awarded the $17.3 million contract to Rockwell to build two remotely-piloted vehicles under the Highly

In my opinion, HiMAT is the ultimate non-stealth compromised, pure aerodynamic efficiency fighter, and is the only true F-16 replacement. What might have been. Someday in the future, when (radar) stealth is finally rendered useless by improved radar technology, this is the kind of fighter we will see. I first saw it in the January 1981 National Geographic issue that covered Mt St Helens. It's as radical today as it was then.
 
Well, according to Dan Raymer, who worked on Rockwell's ATF and worked a HIMAT-based baseline and a new design by Dan, the HIMAT design was only good at transonic speed and was no good for supersonic manoeuvrability or supercruise compared to Dan's new ATF design.
