Radio altimeter large-angle test system, unmanned aerial vehicle and implementation method

Abstract

The invention discloses a radio altimeter large-angle test system, an unmanned aerial vehicle and an implementation method. The system comprises an angle locking shaft; the angle locking shaft is provided with a test platform; a radio altimeter, a wireless data radio station and an altitude recorder are arranged on the test platform; the radio altimeter is provided with antennas; a certain included angle is formed between the antennas and a horizontal plane; the unmanned aerial vehicle is provided with the test system. In order to realize the normal operation of the test system, the implementation method is provided. With the radio altimeter large-angle test system, unmanned aerial vehicle and implementation method of the invention adopted, the angles of the antennas can be adjusted on theground with simple operation and high adjustment precision, and the angles do not change during a flight process, and therefore, test data can be kept stable and normal, all data backhauls are recorded during a period from a take-off phase to a time point when the unmanned aerial vehicle flies to a specified altitude, and the problem that the unmanned aerial vehicle cannot make large-angle rollover in the air can be solved, and flight difficulty is reduced.

Description

technical field [0001] The invention relates to a radio altimeter large-angle testing system, an unmanned aerial vehicle and a realization method, and belongs to the technical field of wireless data transmission and aircraft with rotors. Background technique [0002] At present, the signal return of the known test radio altimeter is all through the real-time data return of the aircraft in the air. In the high-angle test state, the aircraft changes the flight attitude in the air, adjusts the roll to change the flight angle, and sends back data. In this state, due to reasons such as aircraft power and air environment, the angle to be tested cannot be maintained for a long time, which affects the test. Data Accuracy. In addition, the aircraft cannot change its flight attitude immediately after taking off from the ground and reaching a specific altitude, so it is impossible to test the data return of the altimeter from the ground stage, resulting in no data at this stage. Con...
