Different program but this sounds like #2vulture said:Hi all;
I honored and humble to be among you guys - this bunch has got to be the world's foremost aircraft experts. Just wondering if anyone here has images of the following? I've searched through the back pages of this forum and have not found them - any help you guys?
1. still images of a cone shaped (of course with wings) USAF CGI TAV that followed the SR-71.
It was featured in a video in late 1990 by the USAF as a public service T.V. ad - name of the video was "Blackbird."
2. Image of a futuristic stealth fighter launching a Have Dash II tri-mode seeker AAM concept.
3. Images of the beautiful American Jet Industries Perigrin two seat (side by side) jet trainer.
Any help on this request for images will be most appriciated by me - in advance thanks

The Air Force plans to conduct four to six free flight tests of its Have Dash 11 missile starting this spring to collect data on the performance of an advanced bank-to-turn autopilot capability, which could be used as a future AIM-120 Advanced Medium Range Air-to-air Missile (AMRAAM) upgrade, service officials reported.
While no stated requirement currently exists for a new air-to-air missile such as Have Dash, the program is being carried out to demonstrate a broad spectrum of technologies that could be incorporated into next generation air-to-air missiles or used as pre-planned product improvements (P31) to existing missiles, Richard Mook, chief of the service's Air-to-air Technology Integration Section at Eglin AFB, told Defense Daily in a written response to questions. The Air Force's Wright Laboratory Armament Directorate is conducting the program with Loral Aeronutronic, Newport Beach, Calif.
Have Dash's bank-to-turn capability could find its way into the AMRAAM if a variable flow ducted rocket engine is selected for AMRAAM during phase two of the P31 effort, an Air Force spokeswoman told Defense Daily. The special rocket engine, to be considered as an upgrade to AMRAAM for Lot 10 production, would use atmospheric oxygen to burn fuel, eliminating the need for AMRAAM to carry a solid oxygen source, she said.
If the variable-flow rocket engine is chosen, however, AMRAAM--a skid-to-turn missile-- would have to be converted to a bank-to-turn missile during phase three of P31, she explained.
AMRAAM program officials are watching Have Dash carefully to see if all tests are positive and if such technology can be perfected, she added.
"The key technology to be demonstrated (with Have Dash) is the modern control multivariable bank-to-turn autopilot," Mook said. "Bank-to-turn autopilot technology is required to maximize performance of future air-to-air missiles if they are asymmetric in shape due to aircraft integration considerations or because they have airbreathing propulsion."
The program also will test the missile's advanced processor, fin and lug folding ability, advanced control actuator and composite airframe, Mook said. Extensive Have Dash wind tunnel and required flight qualification testing has been carried out, as well as captive carriage compatibility flight testing to demonstrate the missile's structural integrity, aircraft electrical compatibility and aircraft handling qualities, Mook added.
Have Dash II is comprised of an ALM-7E rocket motor, advanced guidance navigation and control computer, AIM-120 inertial measurement unit, fin and launch lug folding mechanisms, high performance electro-mechanical control actuation system and advanced bank-to-turn autopilot. The basic missile airframe was developed during the Have Dash I program conducted by the laboratory in 1985-88.
"The Have Dash missile concept was developed with a heavy emphasis on efficient integration with advanced launch aircraft," Mook said. "This means that carriage of the weapons must not impact the aircraft's flight performance or survivability. Therefore, the Have Dash airframe is designed for low-drag conformal external carriage and also combat internal carriage ... also compatible with more conventional pylon carriage arrangements."
In addition, Mook said a series of projects currently are being considered to enhance Have Dash's electronics assemblies to make the weapon more state-of-the-art. This would reduce the number of parts in the weapon and inherently improve producibility and reliability, he said, noting that contracts have not yet been awarded for these projects.

The Boeing pod is optimized for that aircraft, and does not require specialized weapons.
USAF Have Dash II Missile Desktop Model
This Have Dash II model was produced by Loral's Aeronutronic Division for award to USAF program personnel and flight test team members. The composition of the model is unknown, but likely the fuselage is wood and the fins are plastic or aluminum. The base is solid hardwood and the support arm is acrylic. The missile is detachable from the base.

Have Dash Program Summary:
Have Dash I was a classified project to develop an air-to-air missile for use by stealth aircraft. The concept, developed by the USAF Armament Laboratory at Eglin AFB between 1985 and 1988. Have Dash II, initiated in 1990, was a renewed effort to develop a stealthy air-to-air missile, intended to be used by the Advanced Tactical Fighter - the YF-22 and YF-23 - and to replace the AIM-120 AMRAAM in service.
Have Dash II was designed with a composite body, trapezoidal in shape. This was intended both to reduce the missile's radar-cross-section and to resist heat at hypersonic speeds, as the missile was intended to operate at Mach 5. The body shape also allowed flush external carriage aboard the launching aircraft, and provided aerodynamic lift, making the missile more maneuverable.
The prototype Have Dash II missiles were recoverable, and utilized Rocketdyne Mk 58 solid-fueled rocket motors of the same type used by the AIM-7 Sparrow. Production missiles were expected to be powered by a ramjet engine, and would use inertial navigation during the cruise phase of flight, with a dual-mode infrared/active radar seeker head for terminal guidance.
Flight testing of the prototype Have Dash II missiles was expected to begin in 1992; testing was conducted with the missile being considered for further testing of advanced air-to-air missile concepts.

is this referring to the two-page spread that was used in ad in an old AW&ST issue? Somewhere I think I have some lithographs of that, and the companion cutaway illustration, that I got from Loral at the time.vulture said:

Conformal missiles really belong to the "supercruise with reduced RCS" era. Its a lower drag solution to weapons carriage without the space and weight penalty of an internal bay. With the advent of stealth, the RCS penalty of conformal missiles became unacceptable.quellish said:Shaping may have reduced the *missiles* RCS, but it is unlikely that it was a good thing for the aircraft RCS.
