Aerodynamic electromagnetic simulation test device

Abstract

The invention provides an aerodynamic electromagnetic simulation test device. The aerodynamic electromagnetic simulation test device comprises an electrifying solenoid, a model fixing device, a loading snap ring, a power switch and a programmable power supply; the electrifying solenoid which is in a hollow cylindrical shape is used for generating axial uniform magnetic fields with identical magnetic induction line directions; the model fixing device which is arranged at one end of the electrifying solenoid is used for fixing a test model within a hollow range of the electrifying solenoid; the loading snap ring comprises a snap ring and a lead; the snap ring is a concave groove which is made of non-conducting materials and can be snapped under the test model; a plurality of leads pave inside the concave groove in a parallel mode; the directions of the leads are perpendicular to those of the magnetic induction lines; every lead is divided into a transverse lead section which paves on the bottom surface of the concave groove and a vertical lead section which paves along the concave groove wall; the leads are connected with the programmable power supply through the power switch after being in parallel connection. The aerodynamic electromagnetic simulation test device achieves real simulation of dynamic aerodynamic loads of an aircraft through Ampere force.

Description

technical field [0001] The invention relates to aerodynamic ground simulation, in particular to an aerodynamic electromagnetic simulation test device, and belongs to the field of aerospace engineering. Background technique [0002] Generally speaking, research on aircraft tests will take the form of wind tunnel tests. For large flexible aircraft, its wing structure usually has the characteristics of large scale, light weight, low frequency, and large deformation. The structural characteristics of the aircraft usually require the test model, especially the wing model, to be similar in shape to the prototype, and to have similar stiffness and mass distribution, which makes the design of the test model extremely laborious. On the other hand, the high cost of the wind tunnel test also makes it difficult to repeat the test, and the Reynolds number and boundary conditions of the wind tunnel test are also difficult to be completely consistent with the real flight conditions.
