It depends on chemicals that you are using.

Back to trolley - it is pure concept, nothing that was actualy built. But in general, it resembles me some proposals from Piasecki.

Are you sure nothing was built? For some reason I've got it stuck in my head that they actually tried it out with an F-101 Voodoo.

I am sure that in relatinon with this picture - it means with F-15, not any real hardware was built. And with other planes - I assume that howercraft trolley was never tested. But I will be happy corrected with some evidence.

I know the F-15 was never tested. What I'm saying is that I think it made it to a hardware stage but they used the F-101 instead of the F-15 (cheaper if they wrecked it I'm assuming). Don't know if it was just a mockup, just did tow testing, or what but I'm pretty sure they didn't accomplish any takeoffs. Wracking my brains trying to remember where I'd seen it. Might have been an old Airforce magazine. Ah well. Next time I'm digging around in my shed I'll look for it. :-[

Meh. I can't find anything online. I did find this wind tunnel model of an F-4 being tested on one though.

This is the abstract to the article:

The official name of the program was Advanced Alternate Takeoff System (AATS)

I wasn't completely delusional. Going through an old magazine there was the picture of the two F-15s taking off on the ACV sleds and on the very next page was this picture: (Explains how they got linked in my head over 20 years. :-[ )

The idea of the Alternative Aircraft Takeoff System (AATS) originated at the Flight Dynamics Laboratory at Wright-Patterson Air Force Base in Dayton, OH. AATS called for the development of a ground-effect vehicle to serve as a support platform enabling combat aircraft to take off from bombed or otherwise damaged runways.

The unmanned hover platform would use its own power for ground effect ascension only; the aircraft's jet engine or engines would accelerated both the plane and the AATS to takeoff speeds. On actual take-off, the aircraft's wheels would leave the wells built into the hover platform and drogue parachutes would deploy automatically to slow and eventually halt the AATS for retrieval.

Photograph of 1/10-scale F-4 mockup, borrowed from the Navy, and AATS used by Bell Aerospace for wind tunnel testing.

Wyen, Gerald R. USAF Testing in Support of Air Cushion Equipment Transporter (ACET) Technology.
Wright Lab Wright-Patterson Air Force Base OH May 1987

Abstract:
The Air Cushion Equipment Transporter (ACET) is designed as an air base survivability item, to transport vital heavy equipment (especially aircraft) across battle damaged terrain. This report presents the results of the first ACET program which consisted of the design, construction, and testing of a prototype vehicle. Based upon the design concept evolved for the AATS program, the ACET is essentially a lower performance derivative of the vehicle proposed for that program. Its construction follows closely the methods used in producing the LACV-30 and its cushion lift air system employs almost exclusively the hardware previously installed on the XC-8A aircraft used in the ACLS program. This report summarizes the evolution of the prototype vehicle and presents the results of the test program with the ACET equipped with a full-fingered skirt carrying on F101B aircraft to simulate realistic payloads.
