Title:
INFRARED ENHANCER WITH CONTROLLABLE RADIATION POWER
Document Type and Number:
WIPO Patent Application WO/2020/107844
Kind Code:
A1
Abstract:
An infrared enhancer with controllable radiation power, relating to the field of unmanned aircraft, and capable of solving the problem of the difficulty of controlling the radiation power of infrared enhancers. The infrared enhancer comprises: a support assembly; a turbojet engine (4) fixed inside the support assembly; a mounting adapter (2) used for connecting a product to be mounted and being arranged at one end of the support assembly and positioned to one side of the flame ejected by a tail nozzle of the turbojet engine; and a heating cone (1) fixed at one end of the mounting adapter and facing the position of the tail nozzle of the turbojet engine, the outside of the heating cone being coated in infrared enhancing coating material, and a thermal insulation apparatus being arranged inside the heating cone. The present infrared enhancer uses the flame of the tail nozzle of the turbojet engine to heat the heating cone, and can adjust the temperature of the flame of the tail nozzle by means of controlling the magnitude of the operating state of the engine; the heating cone is heated to form a stable infrared radiation source in order to enhance the target infrared characteristics, simulating the characteristics of the infrared source of an aviation jet engine, and being able to adapt to a greater flight speed domain or height domain.
