The invention belongs to the technical field of aircraft deicing, and particularly relates to an autonomous intermittent deicing device and a mounting method and a deicing method thereof. The autonomous intermittent deicing device comprises a plurality of memory material brackets and an electric heating module, and the plurality of memory material brackets are connected with the electric heating module; when the memory material brackets are arranged on the inner wall, the electric heating module has two states: wherein in the first state, the contact surface of the electric heating module is not in contact with the inner wall; in the second state, the contact face of the electric heating module makes contact with the inner wall. The electric heating module instantly and quickly heats the ice layer locally, and air pressure brought by vaporization of the contact surface of the ice layer and the inner wall can crush the ice layer in a large range; compared with slow heating in the priorart, the device has the advantage that the energy utilization rate of deicing in unit area is higher; and the device also has the advantage of simple and reliable structure.
本发明属于飞行器除冰技术领域,具体涉及一种自主间歇式除冰装置及其安装方法和除冰方法。其中一种自主间歇式除冰装置,包括记忆材料支架和电加热模块,所述记忆材料支架设置若干个,若干个记忆材料支架连接电加热模块;所述记忆材料支架设置在内壁上时,使电加热模块具有两种状态;状态一:电加热模块的接触面与内壁不接触;状态二:电加热模块的接触面与内壁接触。电加热模块对冰层局部瞬时快速加热,冰层与内壁接触面汽化带来的气压可以破碎较大范围冰层;对比现有技术中缓慢加热,本发明具有单位面积除冰的能量利用率更高的优点;且本发明还具有结构简单可靠的优点。
