The invention discloses a self-starting test device for a given blockage degree of an inlet. The self-starting test device comprises an inlet having an extension section at an outlet end and a delay signal generator provided internally with an electromagnetic power supply. The extension section is provided internally with an obstacle, is provided with displacement sensors at two sides for measuring the position of the obstacle and is provided with an electromagnet at a lower end. The obstacle and the electromagnet are connected through an obstacle connecting piece, one end of the obstacle connecting piece is in contact with the lower end of the electromagnet, and the other end is of the obstacle connecting piece is fixedly connected with the obstacle. Each displacement sensor comprises a sensor body and a sliding pull rod that is fixedly connected with the obstacle connecting piece. The self-starting test device for the given blockage degree of the inlet in the invention obtains a complete unstarting oscillation cycle, meanwhile, investigates the self-starting process within an effective operating time range of a wind tunnel, and quantitatively records the process by means of the displacement sensors, thereby ensuring the effectiveness and repeatability of the self-starting test.
Description
technical field [0001] The invention belongs to the technical field of special blowing test. More specifically, it relates to a self-starting test device for constant clogging degree of an intake passage. Background technique [0002] As a key aerodynamic component of the air-breathing high-speed propulsion system and an important component of the propulsion system integration, the air intake is located at the most upstream of the flow channel of the propulsion system. The working characteristics of the air intake will directly affect the overall performance of the propulsion system. In particular, the start of the intake port is the prerequisite to ensure the normal and efficient operation of the intake port, but the actual flight causes the intake port to fail to start (such as the working Mach number is too low, the flight attitude angle is too large, the engine is not adjusted properly, etc. Control factors) are very numerous, so that the problem of non-starting of the ...
