Title:
PULSE DETONATION ENGINE
Document Type and Number:
Japanese Patent JP3952202
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pulse detonation engine of an air suction type that uses oxygen in open air for an oxidizer, in which high pressure and high density are achieved in a mixed gas charging process to a combustor.
SOLUTION: An outlet valve 20 that can be opened and closed is provided at an outlet of the combustor 15, and an air cooler 12 is provided at an outlet part of an intake. Air taken from the intake is heat-exchanged with a low temperature medium at the air cooler 12 to increase density. In the mixed gas charging process, an outlet valve 20 provided at the outlet of the combustor is closed. A detonation process can thus be started without expansion of high-pressure and high-density air obtained by ram compression at the intake.
