"Here is a pic of an SR-71 testing the Aerospike engine. The Aerospike had to be shutdown because it pushed the SR-71 to its aerodynamic
This is not true.
The aerospike test article was carried on a doral fairing on the SR-71 (as seen in the photo), but it was never actually ignited. The test pod was
carried on seven flights for aerodynamic data and cold flow tests, but there was never a hot-fire test.
Also, no Linear Aerospike SR-71 Experiment (LASRE) flight ever exceeded, or even approached, the Blackbird's normal maxmum cruising speed. Here is a
list of LASRE test flights:
31 OCT 97 : LASRE pod aerodynamics. Ed Schneider/Bob Meyer. Max. Mach=1.19, Max. Altitude=33,000 ft.
19 DEC 97 : LASRE pod aerodynamics. Rogers Smith/Marta Bohn-Meyer. Max. Mach=1.61, Max. Altitude=50,050 ft.
04 MAR 98 : LASRE cold flow test. Schneider/Meyer. Max. Mach=1.58, Max. Altitude=41,300 ft.
19 MAR 98 : LASRE cold flow test. Smith/Bohn-Meyer. Max. Mach=1.63, Max. Altitude=50,050 ft.
15 APR 98 : LASRE planned ignition test (failed to ignite), LOX carry. Schneider/Meyer.
Max. Mach=1.78 (fastest LASRE flight), Max. Altitude=51,000 ft. (highest LASRE flight)
23 JUL 98 : LASRE LOX cold flow test, pod purge evaluation, crew proficiency. Smith/Bohn-Meyer. Max. Mach=0.92, Max. Altitude=32,350 ft.
29 OCT 98 : LASRE LOX cold flow test, pod purge evaluation, final LASRE flight. Schneider/Meyer. Max. Mach=1.40, Max. Altitude=41,200 ft.
