PROPULSION ASSEMBLY AND METHOD

摘要

The invention relates to the field of aerospace propulsion, and more particularly to a propulsion assembly having at least one channel defined by an inner wall and an outer wall, the channel presenting an inlet opening and an outlet opening, the assembly including a plurality of rocket engines oriented axially in the channel and forming ejectors for accelerating a flow of air in the channel to supersonic speed. Downstream from the outlet opening from the channel, the inner wall forms a single expansion ramp nozzle. The invention also provides an aerospace craft and a method of propulsion using such a propulsion assembly.

主权项

1. A propulsion assembly comprising at least:
a channel defined by an inner wall and an outer wall and presenting an inlet opening and an outlet opening, said inner wall forming, downstream from said outlet opening of the channel, a single expansion ramp nozzle; a plurality of rocket engines oriented in an axial direction in the channel and forming ejectors for accelerating a flow of air in the channel to a supersonic speed; turbopumps for feeding oxidizer and fuel, said turbopumps being situated axially behind said outlet opening of the channel on the inside of said inner wall; and a gas generator for actuating said turbopumps.
