Title:
NOZZLE STRUCTURE, JET DEVICE AND ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/127936
Kind Code:
A1
Abstract:
Provided are a nozzle structure, a jet device and an engine. The nozzle structure (2) comprises: a nozzle body (10), the nozzle body (10) being provided with a liquid flow channel (11), with a first end of the liquid flow channel (11) being a liquid inlet port (12), and a second end of the liquid flow channel (11) being a liquid jet port (13); and a swirler (20), the swirler (20) being disposed in the liquid flow channel (11) and located at the liquid jet port (13). The nozzle body (10) is further provided with an air flow channel (14), with a first end of the air flow channel (14) being an air inlet port (15), and a second end of the air flow channel (14) being an air jet port (16). The air jet port (16) is spaced apart from the liquid jet port (13) so as to exert a shearing action on a tapered atomized liquid fuel jetted out of the liquid jet port (13). The jet device solves the problem of the performance of a liquid rocket engine being affected by incomplete combustion of the liquid fuel due to the poor atomization effect of jet devices in the prior art on the liquid fuel.
