[QUOTE="shockonlip, post: 47269, member: 1144"] [quote="blackkite"] Hi overscan! My opinion is same as yours! Turbofan ramjet engine! Very impressive. Some kind of variable cycle engine? Is it fail to develop? [/quote] The technology for these kinds of engines are still being developed. For example, the recent GE57 studied under the Revolutionary Turbine Accelerator (RTA) program, which was for a ground demonstration engine to demonstrate mode transition from an augmented turbofan to a ramjet to demonstrate the thrust level required to accelerate a future hypersonic vehicle to scramjet take over speed.
