Problems solved by technology

The design of the control law after the carrier-based aircraft leaves the ship only considers the design of the longitudinal control law, but does not study the design of the lateral control law, and the designed control laws require the pilot to operate the corresponding throttle or elevator. It will cause greater operational burden and psychological pressure to the pilot

Abstract

The invention discloses a shipboard aircraft ski-jump take-off automatic flight control method. According to the method, a longitudinal automatic flight control system, a lateral automatic flight control system and an automatic throttle control system are adopted to control the ski-jump take-off and flight of a shipboard aircraft. The method comprises the step of taking a damper and a stability augmentation system as an inner loop to generate and transfer a vertical climb speed instruction to ensure that the vertical speed of the shipboard aircraft can be automatically tracked and stable, and can be used for effectively suppressing and eliminating the lateral deviation and sideslip angle, so that the shipboard aircraft can keep lateral stability and can safely take off from an aircraft carrier. The method is based on a PID control method and is simple in realization process and stable in control process. Simulation experiments prove that the shipboard aircraft ski-jump take-off automatic flight control method has the advantages of well enabling the shipboard aircraft to automatically flying at a given vertical climbing speed after ski-jump to take off, ensuring that the shipboard aircraft can safely take off from the aircraft carrier and lightening the operation pressure of the driver.

Description

technical field [0001] The invention relates to the technical field of take-off control of carrier-based aircraft, in particular to an automatic flight control method for ski-jump take-off of carrier-based aircraft. Background technique [0002] Ski-jump take-off means that the carrier-based aircraft first relies on the thrust of its own engine to accelerate and run on the horizontal deck of the aircraft carrier, and then passes through the inclined and curved deck of the bow of the aircraft carrier, so that the carrier-based aircraft is given a certain positive direction when it leaves the ship. The inclination angle of the track and the upward vertical speed make the carrier-based aircraft jump into the air and complete the take-off from the ship. So ski jump takeoff is also called inclined board takeoff or inclined surface deck takeoff. Compared with catapult takeoff, ski jump takeoff has a relatively low technical threshold, is economical and practical, and is widely us...
