Astrium has done considerable work already on the Romeo rocket engine that would power the climb to space, and wind tunnel testing has proven the aerodynamic shape.

There is a larger effect of flow Angle of attack caused by high altitude wind on aerodynamic load and flight environment in rocket flighting.

Along with the deep development of study, the microjet technology will be possibly applied to control the aerodynamic flow of the high speed aircraft surface and the thrust vector of rocket engine.
