Embodiment Construction

[0009] The installation and working methods of the present invention will be described below in conjunction with the accompanying drawings.

[0010] (1) System-related hardware installation. The equipment installed in the autopilot system includes: pilot computer, roll steering gear, pitch steering gear, yaw steering gear, switch, trim adapter, mode control board, status indicator board, heading rate Gyros, Air Data Computers, Altitude Selectors, Attitude Indicators, etc. According to the needs of equipment installation, the pilot computer, trim adapter and trim relay are installed in the equipment room on the right side of the cockpit; the roll servo is installed on the roof in the middle of the fuselage, and the pitch servo and yaw servo are installed at the tail; The control switch is installed on the left and right driving wheels.

[0011] (2) Implemented functions

[0012] After the Y12IV machine is equipped with an autopilot, the following functions can be realized:

Abstract

The invention relates to a digital autopilot system of a lightweight fixed-wing aircraft. The digital autopilot system comprises an autopilot computer 1, an attitude indicator 2, a state indication panel 3, a pitching steering engine 4, a rolling steering engine 5, a yawing steering engine 6, a mode control panel 7, a balancing adapter 8, a balancing relay 9, a steering wheel switch 10, an audio alarm box 11, a height selector 12, a course rate gyroscope 13, an atmosphere data computer 14, a control system steel rope 15, an aileron trimmer control system 16, an elevator trimmer control system 17, a power supply system 18, a balancing switch 19 and a navigation system 20. The system is complex in control law and is capable of controlling an aircraft to realize the automatic pilot and other functions based on signals input into a heading and attitude system, a pitot-static system, a radio navigation system and other systems of a receiver. Meanwhile, the operation stability of the entire aircraft is improved, and the operation intensity of a pilot is reduced. Moreover, the security and the reliability are improved, and the comfort level of passengers is improved.

Description

technical field [0001] The invention belongs to the field of automatic flight control, and relates to a digital automatic pilot system of a light fixed-wing aircraft. Background technique [0002] At present, for the Y12II, Y12IV and Y12E models, neither the certified state nor the aircraft under production is equipped with an autopilot system. Pilots need to pay attention to the flight status of the aircraft at all times, and the operational burden is relatively heavy. Aircraft are susceptible to unsteady airflow, and passenger comfort is relatively low. Contents of the invention [0003] The technical problem to be solved by the present invention: the problem that the Y12II, Y12IV and Y12E type machines do not have an autopilot system at present. [0004] The technical solution of the present invention: a light fixed-wing aircraft digital autopilot system, including an autopilot computer 1, an attitude indicator 2, a status indicator board 3, a pitch steering gear 4, a ...
