Abstract

The invention discloses an adjustable-included angle support plate-type combustion stabilization device for a scramjet engine. The adjustable-included angle support plate-type combustion stabilizationdevice comprises two combustion stabilization support plates (1), connection hinges (2), adjustment support plates (3), two strong magnets (4), an oval wheel (5) and a stepping motor (6), wherein oneside of each combustion stabilization support plate (1) is connected by the connection hinges (2), an included angle between the two combustion stabilization support plates (1) is an acute angle, twoadjustment support plates (3) are respectively connected with the other sides of the two combustion stabilization support plates (2) by the hinges (2), the two strong magnets (4) are respectively andclosely assembled with the other sides of the adjustment support plates (3), the oval wheel (5) is closely matched with the two strong magnets (4) by attraction forces of the strong magnets (4), andthe stepping motor (6) is placed at a middle part of a cavity formed by connection of the two combustion stabilization support plates (1) and is connected with the oval wheel (5). By the adjustable-included angle support plate-type combustion stabilization device, the problem that the included angle between the support plates during the working process of existing scramjet engine with stable support plates cannot be adjusted is solved.

Description

technical field [0001] The invention belongs to the field of scramjet experiments, in particular to a support-plate type combustion stabilizing device with adjustable angle for scramjet. Background technique [0002] Scramjet experimental research began in the 1990s. Ghodke mentioned a strut plate-stabilized scramjet combustion chamber in "Numerical and experimental studies of flame stability in a cavity stabilized hydrocarbon-fueled scramjet". The engine can The support plate is used to stabilize the combustion and flow characteristics of the flow field in the combustion chamber of the engine. However, the structure of the support plate of the tester is not adjustable, and the angle of the support plate cannot be adjusted during the experiment. In the article "Experimental study of cavity-strut combustion insupersonic flow", Hsu mentioned a strut-strut stability tester, which can disturb the internal flow field of the engine through the strut and cavity, thereby affecting ...
