Abstract

The invention discloses a support plate type combustion stabilizing device with adjustable included angle for a scramjet engine. Including combustion stabilizing support plate (1), connecting hinge (2), adjusting support plate (3), strong magnet (4), elliptical wheel (5) and stepping motor (6); among them, combustion stabilizing support plate (1) The number is 2, one side of the two combustion stabilization struts (1) is connected by a connecting hinge (2), and the angle between the two combustion stabilization struts (1) is kept as an acute angle; the two adjustment struts (3) are respectively It is connected with the other side of the two combustion stabilizing support plates (1) through a hinge (2); two strong magnets (4) are tightly assembled with the other side of the adjusting support plate (3) respectively; the oval wheel (5) relies on strong The suction force of the magnet (4) is closely matched with the two strong magnets (4); the stepper motor (6) is placed in the middle of the cavity formed by the connection of the two combustion stability support plates (1), and is connected with the oval wheel (5) . The invention solves the problem that the included angle of the support plate cannot be adjusted during the working process of the current support plate stabilizing scramjet engine.

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 ...
