Patent ID: 7464534

Claim:
A pulsed detonation engine having 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, wherein: said transverse base of the flame tube is 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; at least one supply opening for said combustible charge is provided in a lateral wall of said flame tube, said supply opening being closed off and separated from said combustion chamber by said movable transverse base when said movable transverse base is occupying the first position and being in fluid communication with said combustion chamber when said movable transverse base is occupying the second position; and in said first position, said transverse movable base is secured to said flame tube by a releasable locking unit.
