Icing detection system for medium-large transport plane

Abstract

The invention belongs to the technical field of ice prevention and removal, and relates to an icing detection system for medium and large transport aircrafts. The ice melting device is composed of an icing sensor, an ice melting sensor, a temperature sensor, an ice melting effect solver and an icing detection controller. The icing sensor senses the thickness of an ice layer of the main machine body through a vibrator assembly extending out of the machine; the ice melting sensor senses the thickness of an ice layer on the outer surface of the wing through the vibrator assembly of the embedded flat die structure. The temperature sensor plays a role in assisting in judging the icing environment; the ice melting effect resolver judges whether ice is accumulated on the surface of the ice melting sensor by resolving the frequency signal; and the icing detection controller judges whether the icing sensor is in an icing environment or not by resolving the frequency signal and the temperature signal, and transmits ice melting information and system working state information to the upper computer at the same time. The icing condition of the nose and the main fuselage can be detected, and the icing condition of the outer wing and the horizontal tail can be effectively detected. In the system, only the icing detection controller and the upper computer transmit icing information.

Description

technical field [0001] The invention belongs to the technical field of anti-icing and relates to an icing detection system for medium and large transport aircraft. Background technique [0002] When an aircraft flies in icy weather conditions, icing will occur on its surface, which will seriously threaten the flight safety of the aircraft. In recent years, the problem of aircraft icing has attracted more and more attention. In order to reduce its impact on aircraft flight safety and performance, it is very necessary to detect icing conditions. By detecting the icing situation on the surface of the aircraft, an icing warning signal can be sent to the flight crew in time, so that measures can be taken to deal with the ice layer, so as to minimize the impact of the icing situation on the aircraft. [0003] The icing detection device is a special detection and warning device used to detect whether there is icing on the surface of the aircraft when the aircraft is flying under i...

Problems solved by technology

Currently commonly used icing detection devices are composed of icing sensors and icing detection controllers, which can only detect icing conditions at the nose. For medium and large transport aircraft, the detection capability and detection range of this type of icing detection device Limited, with certain flaws, unable to effectively detect wing icing

[0004] In order to reduce the possibility of flight accidents caused by icing of the aircraft, ensure the safe flight of the aircraft under icing weather conditions, and meet the icing detection requirements of medium and large transport aircraft, the present invention optimizes the design on the traditional icing detection device, To make up for the previous lack of narrow detection range, combined with the structure of medium and large transport aircraft, design and develop an icing detection system for medium and large transport aircraft
