UAV Key Technology And Development Trend

The UAV is the Unmanned Aerial Vehicle, a non-manned aircraft that uses radio remote control equipment and self-contained program control devices, including unmanned helicopters, fixed-wing aircraft, multi-rotor aircraft, and unmanned airships. Unmanned parachute wing. Broadly speaking, it also includes adjacent space vehicles (20-100 km airspace), such as stratospheric airships, high air balls, solar drones, etc. From a certain point of view, the drone can complete complex air missions and various load tasks under unmanned conditions, and can be regarded as an "airborne robot." Among them, the flight control system, navigation system, power system and communication link are the core technologies of the UAV system, which is the factor for the UAV manufacturers to obtain the core competitiveness at this stage. Below we focus on the role and development of the next four systems.

The flight control subsystem is the core system of the whole flight process of the drone to complete take-off, air flight, mission execution and return-to-field recovery. The flight control is equivalent to the driver's role in manned aircraft, and is the core of the drone. One of the technologies. The flight control generally includes three parts: the sensor, the onboard computer and the servo actuating device. The functions realized mainly include the three types of unmanned aircraft attitude stabilization and control, drone mission equipment management and emergency control.

Among them, various sensors (including angular velocity, attitude, position, acceleration, altitude and airspeed) assembled by the aircraft are the basis of the flight control system and are the key to ensure the accuracy of the aircraft control. In different flight environments, different types of UAVs have different sensor configuration requirements. In the future, the demand for UAV situational awareness, the ability to identify the enemy and the enemy on the battlefield, and the diplomatic capability of the defense zone require that the UAV sensor has higher detection accuracy and higher resolution, so it is widely used in UAV sensors at home and abroad. New technologies such as hyperspectral imaging, synthetic aperture radar, and ultra-high frequency penetration.
