Special test device of ice ingestion of turboprop engine

Abstract

The invention provides a special test device of ice ingestion of a turboprop engine. The device comprises a support, an ice feeding track, a moving adjustment support, a heat insulation box, an electromagnet and a horizontal support plate. The moving adjustment support comprises a horizontal moving track and an adjustment support. The angle between the ice feeding track and the adjustment support can be changed by moving the adjustment support along the horizontal moving track, so that the feeding speed and angle of ice blocks can be adjusted. Balance and inclination of the heat insulation box is controlled by connection and disconnection of current inside the electromagnet. Furthermore, a plurality of screw holes are arranged in the adjustment support to adjust the heights of the ice feeding track, the heat insulation box and the electromagnet. A plurality of screw holes are arranged in the support for fine adjustment of the height of the ice feeding track. A straight track of the provided ice feeding track is composed of a plurality of segments, so that the height of the ice feeding track can be adjusted. The device can conduct coarse adjustment and fine adjustment of the included angle between the ice feeding track and the adjustment support either horizontally or vertically. The structure is simple, the production cost is low, the adjustment method is smart and flexible, the adjustment range is wide, and the adaptability is high. The device can quickly and easily control the ice feeding speed and angle.

Description

technical field [0001] The invention relates to the technical field of engines, and more particularly, to a special test device for ice swallowing of a turboprop engine. Background technique [0002] During the flight, the aircraft often encounters sudden hail from the sky. Damage to the shell or other parts of the aircraft will seriously affect the operation of the aircraft and the safety of passengers in the aircraft. Especially when the hail enters the engine, the hail Damage to the blades of the engine may have serious consequences. Therefore, before the aircraft is put into use, a device needs to be studied to carry out the ice swallowing special test on the engine of the aircraft. [0003] The device should be able to store a piece of ice (10-20) min at a certain temperature, and can be remotely controlled to release the ice. The speed and angle of the ice sheet sliding out of the ice throwing device should be controllable. Contents of the invention [0004] The te...
