Continuous detonation wave engine and aircraft provided with such an engine

摘要

The invention relates to a continuous detonation wave engine and aircraft provided with such an engine. The continuous detonation wave engine (1) operates with a detonation mixture of fuel and oxidant and includes, in particular, a detonation chamber (3) comprising an injection base (10), the length of which is defined along an open line (17), such as to form a detonation chamber (3) having an elongate form in a transverse plane, as well as an injection system (4) arranged such as to inject the fuel/oxidant mixture into the detonation chamber (3) at at least one segment of the injection base (10).

主权项

1. Continuous detonation wave engine operating with a detonating fuel/oxidant mixture and comprising:
at least one detonation chamber (3); a plurality of injection lines (31) for injecting the detonating fuel/oxidant mixture into said detonation chamber at an upstream end (5), said detonation chamber (3) comprising an injection base (10) at said upstream end, and two walls (12, 13) which extend on either side of this injection base; and initiation means (8) which are disposed in said detonation chamber (3), to initiate in the detonating fuel/oxidant mixture a detonation wave (22) which is then propagated in said detonating fuel/oxidant mixture and is the cause of successive self-initiated detonation waves, so as to generate production of hot gases, escaping through a downstream end (9) of said detonation chamber (3), wherein said detonation chamber (3) comprises said injection base (10), so as to form said detonation chamber (3) having an elongate form in a transverse plane, and in that said injection lines are arranged along a propagation direction (F) of the detonation wave (22) so as to inject the detonating fuel/oxidant mixture into said detonation chamber (3) at a plurality of portions (20) of said injection base (10), the plurality of portions (20) arranged along the propagation direction (F); wherein said detonation chamber (3) has a bifurcation (27) at the injection base (10), providing at least two elongate branches (39, 40) beyond said bifurcation, and each of at least two elongate branches (39, 40) can be supplied independently and asymmetrically with detonating mixture by said injection lines (31), forming an annular detonation chamber with concentric extensions (39, 40) having respectively different radii and capable of being supplied independently and asymmetrically by the injection lines.
