Abstract
A rocket engine according to the invention has a body generally extending along an axis and adapted to move through the air in a predetermined axial back-to-front direction. This body is formed with axially spaced front and rear fuel-containing combustion chambers. A nozzle centered on the axis and extending axially backward in the body from the front chamber has a rear nozzle end directed axially backward so that gases generated in the front chamber by combustion of the fuel therein form a fan-shaped jet extending axially backward from the rear nozzle end. The injector of this invention comprises a front tube centered on the axis, having an upstream end sealed to the nozzle upstream of the rear nozzle end, and having a rear downstream end formed with an outside bevel and located axially downstream of the jet formed by the nozzle, and a rear tube secured to and coaxial with the front tube, radially surrounding same and forming therewith an annular gap open axially upstream, and having an upstream end formed with a bevel and positioned axially forward of the rear nozzle end. A diffuser is provided in or on the body for deflecting outside air axially back into the gap.
