DETONATION CHAMBER OF PULSE-JET ENGINE Russian patent published in 1998 - IPC

FIELD: pulse-jet engines with resonance combustion chambers. SUBSTANCE: detonation chamber includes housing 1 and detonation initiators 2. Housing is made in form of chute 3 widening from bottom to open edge. Housing is divided into many sections by means of partitions 4. Each section is provided with detonation initiator. Each section has form of tetrahedral bell mouth 5 due to definite form of partitions. Bell mouth 5 is widening towards motion of flow; partitions and walls of chamber are provided with holes 6 for passage of air and combustible mixture. Engine. Engine is operated by means of electronic control system 9 connected with detonation initiator. Construction of chamber makes it possible to control magnitude and direction of engine thrust vector, both stepwise and smoothly, in units and in wide ranges which may be achieved through change of amount of working sections of chamber or frequency of detonation processes or asymmetric connection of sections. EFFECT: enhanced efficiency. 1 dwg
