Afterburner based on continuous detonation jet initiation and combustion

Abstract

The application discloses a continuous detonation jet flow initiation and combustion-assisted afterburner, which comprises an outer channel case, an inner channel case, a flow regulation support plate arranged radially on the inner channel case, a center cone, a duty combustion chamber arranged on the flow regulation support plate, a V-shaped flame stabilizer arranged on the flow regulation support plate corresponding to the duty combustion chamber, a continuous detonation jet flow initiator arranged on the outer wall of the inner channel case, and a porous stationary vortex injector arranged at the jet flow outlet of the continuous detonation jet flow initiator. The inner channel utilizes continuous detonation combustion products as the conventional afterburning after the duty flame is strengthened and stabilized, and the outer channel is detonated for afterburning through the continuous detonation jet flow initiation mechanism. The continuous detonation partitioned strengthened combustion organization scheme is helpful to realize the wide-range high-efficiency low-resistance working requirement of the advanced afterburner.
