| 摘要 |
The invention relates to a pulse detonation engine and a method for initiating detonations in a pulse detonation engine. The pulse detonation engine ( 1 ) comprises a combustion chamber ( 2 ), an igniting device ( 3 ) and a fuel injection device ( 4 ) with a plurality of injection valves ( 5 ) arranged in the axial direction ( 20 ). The injection valves ( 5 ) are arranged in the longitudinal direction of the engine for sequence-controlled injection of fuel ( 6 ) into the combustion gases ( 7 ) remaining from the preceding detonation. This provides a mixture of fuel and free radicals that facilitates the forming of a detonation.
