According to the invention, the said engine (I), which comprises at least one flame tube () with a mobile transverse end wall (), comprises an external envelope () around the said flame tube (), which defines a peripheral annular space () in which fixed flow guides () are positioned, these flow guides forming flow channels () for the air, and at least one mobile plug (), connected to the said mobile end wall (), to close off and open one of the flow channels ().

Pulse detonation engine

An engine including a means for supplying fuel to the combustion chamber of the fire tube, that includes a variable-volume transfer chamber for receiving fuel, a fuel transfer means from the tank of the engine towards the transfer chamber, and injection means for injecting fuel into the combustion chamber from the transfer chamber. The engine further includes an elastic return at least partially defined by the fuel contained in the transfer chamber.

Pulsed detonation engine

The invention relates to a pulse detonation engine operating with an air-fuel mixture. According to the invention, the engine () includes at least two predetonation tubes () which operate under conditions close to thermal cutoff conditions and the shock waves from which are focused in the combustion chamber ().

Pulse detonation engine operating with an air-fuel mixture

A pulsed detonation engine may include a flame tube with a lateral wall and a transverse base defining a combustion chamber and a supply device cyclically feeding said combustion chamber with a combustible charge. The transverse base of the flame tube may be movable for reciprocating in translation inside said flame tube in order to be able to occupy two boundary positions, a first position corresponding to the detonation phase of the combustible charge in the combustion chamber of said flame tube and a second position corresponding to the phase wherein the combustible charge is supplied to said combustion chamber.
