Innovation: To go where no man has gone before, a rotating turborocket may have the right stuff

Next Steps

Jeff Greason, co-founder of Xcor Aerospace, says the rotating-rocket technology could well prove useful, as long as BSRD can keep the engine’s size comparable to conventional models. Bossard says he can do so with further development, which he expects to cost $2.5 million, and he’s keeping interested Air Force researchers briefed on his progress.
