本发明是一种用于在冰风洞中研究属于航空发动机积冰和防冰技术领域。 The present invention is a method for aeroengine research belong icing and anti-icing technology in the field of ice wind tunnel.
 飞机在高空低于冰点的温度下飞行时，如果穿越含有过冷水滴(温度低于冰点但仍保持液态的水）的云层，水滴碰在飞机表面上，就会在碰撞区域及其附近发生积冰。 Under the  planes temperatures below freezing at high altitude flight, if the crossing containing supercooled water droplets (temperature below freezing but still maintain liquid water) clouds, water droplets hit the surface of the aircraft, it will be in the region and its impact It occurred near the icing. 飞机积冰不但增加了部件重量，而且会改变绕流流场、破坏气动性能，使操纵性和稳定性受到影响，给飞行安全带来危害。 Icing not only increase the weight of the components, but also changes the flow field, destroy aerodynamic performance, handling and stability so affected, harm to flight safety. 近年来，由于对现代航空发动机的运行安全、效率和性能的要求越来越高，有关发动机结冰现象的研究也得到越来越多的重视。 In recent years, due to the operational safety, efficiency and performance of modern aircraft engines have become increasingly demanding, research on engine icing phenomenon has also been more and more attention. 发动机前端(包括整流帽罩、进气机匣及其支板、以及压气机进ロ导向叶片等）通常是出现结冰现象的主要部件。 Engine front-end (including the rectifier cap, inlet casing and the support plate, and ro compressor inlet guide vanes, etc.) are usually the main components of icing phenomena. 其中发动机进ロ整流帽罩的结冰现象对发动机气动性能有重大影响，轻则使发动机的引气量下降，推进功率减小，重则一旦冰块脱落可能造成发动机及其部件的损坏。 Wherein the engine intake ro rectifying cap of icing have a significant impact on the aerodynamic performance engines, ranging from the engine air entrainment decline, propulsion power is reduced, once the heavy ice off may cause damage to the engine and its components. 所以研究整流帽罩的防冰/除冰问题具有重要意义。 So research rectifying cap anti-icing / de-icing issues of importance.
