The SR-71 Blackbird's engines were hybrids; AFAICT they didn't quite use this approach, but instead had a layout where the same engine could function as a conventional jet and a ramjet depending on how fast air was hitting it.

- rbanffy 16y agoHmmm. The J58 is humongous, but it would be kind of cool to use them to start a scramjet (or, better, use it as the basis of another engine that can function in all three modes). The SJX6 combustion chamber is not cylindrical and would not fit around a jet engine the way the J58 works in ramjet regime, but I bet many people are thinking about how to do it right now. A scramjet engine that can take off and land like a more or less ordinary plane (it would certainly not look ordinary) is something very desirable.
