Airflow monitoring system for aircraft in atmosphere

Abstract

The invention belongs to the technical field of aircraft monitoring, and particularly relates to an airflow monitoring system for an aircraft in an atmosphere. The aircraft airflow monitoring system is mainly composed of an anemometer chip array and a pulse neural network sensor. The anemometer chip unit comprises a resonant network and cross-coupled transistors, and the power amplifier circuit comprises input matching, intermediate stage matching and output matching. The anemometer chips are distributed in a honeycomb shape to form an anemometer chip array, the anemometer chips can comprehensively and seamlessly cover the surface of the aircraft through the distribution mode, and information collection completeness is improved. The anemometer chip array converts the surface wind speed of a chip into a frequency signal, and the pulse neural network sensor analyzes the array output frequency signal through operation, so that the surrounding environment condition is identified, the flight state of the aircraft is judged, and the attitude of the aircraft is adjusted.

Description

technical field [0001] The invention belongs to the technical field of aircraft monitoring, in particular to an aircraft air flow monitoring system in the atmosphere. Background technique [0002] Unpredictable wind in the atmosphere is the main disturbance factor for the stable flight of multi-rotor aircraft. Unstable winds will seriously increase the difficulty of controlling the aircraft. If the wind speed is high, the aircraft will be in an extremely unstable state, and there may even be a risk of loss of control. Therefore, the estimation of the airflow around the aircraft is of great significance to the navigation, guidance and control of the aircraft. [0003] In modern aircraft, the motion characteristics of high-altitude atmospheric aircraft are greatly affected by the wind field of the environment. Therefore, real-time and accurate measurement of wind speed and wind direction is the premise of implementing long-term airborne and improving flight control quality. ...

AI Technical Summary

Problems solved by technology

However, the main problem with the pitot tube is that it cannot sense the airflow in all directions of the aircraft, and the pitot tube mainly adopts a mechanical structure, which is large in size and heavy in weight

At present, there is no ready-made product that can be directly used to provide aircraft with flight control of wind speed, wind direction and surrounding airflow conditions at the stratosphere and above altitudes.
