Abstract

The present invention discloses a distortion generator, which includes: a plurality of positioning rods arranged radially between the inner casing and the outer casing of the engine casing along the radial direction of the engine casing; a first magnetic member sleeved on the positioning rods and movable along the length direction of the positioning rods; a distortion member, both ends of the distortion member along the length direction are respectively connected to the first magnetic members of different positioning rods, and the distortion member has elasticity along the length direction; a second magnetic member arranged on the outer casing or the inner casing, and the second magnetic member can drive the first magnetic member to move on the positioning rods in a magnetic induction manner. This distortion generator not only overcomes the defects in the prior art that the structure of the distortion grid is fixed, the compatibility of the distortion grid is poor, and the design, manufacturing and installation costs are high, but also can simulate different total pressure radial distribution laws according to the requirements of different oncoming flow conditions of the engine, which is beneficial to shortening the experimental period of the intake experiment.
