Coupling type icing detection device and method based on airfoil

Abstract

The invention discloses a coupling type icing detection device and method based on an airfoil. On the basis of coupling two or more icing detection methods and with the intention of exploring the icing detection problem of a complex curved surface, a plurality of icing sensors are installed on the surface of an area prone to icing on the premise of guaranteeing the normal performance of the skin,so that the accuracy and precision of complex surface icing detection are improved, accurate icing information input can be provided for low-energy-consumption ice prevention and removal, and the distinguishing problem of large / small-scale super-cooled water drop icing can be measured at the same time. The icing detection object can be a helicopter rotor blade, a rotor aircraft propeller blade, and a wing and empennage surface of a fixed-wing aircraft, can be a blade surface of a wind turbine and a surface of a power transmission wire or can be a windward surface of a part needing icing detection of other national economy related equipment such as a high-speed train. The device and the method have the advantages of good adaptability and wide application range.

Description

technical field [0001] The invention relates to the field of aerodynamics, in particular to an airfoil-based coupled icing detection device and a method thereof in icing wind tunnel tests. Background technique [0002] Icing is a physical phenomenon that widely exists in flight practice, and it is one of the main hidden dangers of flight safety accidents. When the aircraft flies under the ambient temperature below the freezing point or in icing weather conditions near the freezing point, the supercooled water droplets in the atmosphere will hit the surface of the aircraft components, and will be on the wings, tail, rotors, air intakes, windshields, antennas, etc. Icing occurs on the surface of components such as covers, instrument sensors, etc. The icing of the aircraft not only increases the weight of the aircraft, but also destroys the aerodynamic shape of the aircraft surface, changes the flow field around it, and destroys the aerodynamic performance, resulting in a decr...
