J58 jet engine and supersonic flight

In summary, there have been discussions on the SR-71 and its related craft, as well as its J58 propulsion system, on various forums. Some of the SR-71s can be found in museums, including one at Duxford, England. There is a video discussing the J58 and its challenges, such as thermal expansion and cooling. Some humorous anecdotes were also shared, including the use of 400ci Buick V8 engines in the USA. One individual shared their experience living near a Blackbird base and the distinct sound it made during takeoff.

We've had several threads on the SR-71 (and related craft) and the J58 propulsion system.

One can find the SR-71s in various museums around the country, and one is at Duxford, England, one of the bases from which they operated.

I just want to add the following video since it discusses the J58, and of the materials, and some of the challenges for that kind of propulsion system - e.g., thermal expansion and cooling of the engine.

ohhh enjoyed that ... very informative, thankyou :smile:

and with some giggles, specially about using up all the 400ci Buick V8 engines around the USA hahaha

My dad went to college in the early 80s at CSU Chico, not too far away from Beale AFB (home base for the Blackbirds), and he said you could always tell when a Blackbird was getting ready to launch. Sounded like a drag race, but much longer than normal.
