Description

Intelligent icing weather cloud and fog parameter sensor Technical Field The invention relates to the technical field of intelligent sensors, in particular to an intelligent icing weather cloud and fog parameter sensor. Background Icing is a long standing problem in the aeronautical field and constitutes a serious threat to the safe flight of aircraft. During the take-off and landing of an aircraft, impingement with supercooled liquid droplets while traversing the cloud may cause ice formation on the aircraft surface. The ice accumulation not only damages the aerodynamic shape of the aircraft, but also can influence the work of the engine and even cause safety accidents. In order to ensure safe flight of an aircraft in an icing weather environment, ice control systems are becoming critical. Currently, heat deicing is a common approach for aircraft, and the design and efficiency of deicing systems is largely dependent on accurate measurements of the deicing environment. In recent years, measurement of Liquid Water Content (LWC) has been mainly based on a rotary multi-cylinder meter, and although such a device can provide measurement of LWC and average volume diameter (MVD) of water droplets, it is bulky, costly, and has a certain limitation in practical application. With the development of technology, optical-based measurement devices such as Forward Scatter Spectrometers (FSSP), optical Arrays (OAP), and Phase Doppler Particle Analyzers (PDPA) provide more accurate measurement means. However, these devices are often expensive and heavy, and are difficult to train on a large scale for small aircraft such as unmanned aircraft. In general, existing measuring devices have problems in practical applications, such as a) cost, high-precision optical measuring devices are expensive, limiting their use in cost-sensitive applications. b) The weight problem is that the existing equipment has larger weight and is not suitable for small aircrafts such as unmanned aerial vehicles. c) Measurement accuracy existing equipment may not provide sufficiently accurate measurements under certain weather conditions. d) Real-time performance that the existing equipment can not provide real-time measurement data, and the timely response of the ice control system is affected.
