Problems solved by technology

However, because the integrated angle of attack and sideslip angle sensor wind vane is too thin to be heated and deiced, it is easy to freeze and fail when used in rainy, snowy and freezing weather conditions
[0005] The metal structure nose multifunctional air data sensor is installed on the nose, which will cause great interference to the nose radar

Abstract

The invention relates to a multifunctional atmosphere data sensor. The sensor provided by the invention is mounted on the outer wall of an air vehicle and integrates total pressure, static pressure, attack angle and static temperature detection. The sensor provided by the invention is compact in structure, convenient to mount and low in weight. The sensor provided by the invention can make primarytreatment on collected atmosphere data and then the atmosphere data subjected to treatment can be transmitted to an atmosphere data computer or a flight control computer through a bus directly, so that a problem of pressure pipeline transmission delay is avoided. The sensor provided by the invention can be used for deicing through heating and the heating temperature can be controlled through a built-in sensor, so that use reliability in rainy, snowy and frost weather can be ensured.

Description

technical field [0001] The invention relates to a multifunctional atmospheric data sensor, which integrates the detection of total pressure, static pressure, static temperature and angle of attack of an aircraft through a special aerodynamic shape and structure, and adopts digital output after preliminary compensation and correction. Background technique [0002] The multifunctional air data sensor is usually a straight tube design and is installed in front of the nose. It is equivalent to the integration of pitot, angle of attack sensor, sideslip angle sensor and total (static) temperature sensor on a straight pipe. [0003] The multifunctional air data sensor on the nose can output total and static air pressure signals, angle of attack, sideslip angle, and total (static) temperature analog signals to the air machine. However, the pressure output needs to be transmitted through the trachea, the pipeline layout is troublesome, and the transmission delay is relatively large....
