DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Example 1

[0028] Depend on Figure 1-8 The present invention relates to a simulation training device for a flight principle course, comprising a helicopter simulation cockpit 1, a visual device 2, an instructor console 3, a main control and communication device 4 and a flight principle demonstration device 5, wherein the helicopter simulation cockpit comprises a simulation cockpit and cockpit instruments, including a canopy 101, a base 102, a cockpit central instrument panel 103, a control system component 104, and a pilot simulation seat 105, which are used to include a virtual display of cockpit instruments and visual flight information indication; the visual device is composed of a visual generation device 201 and a visual display device 202; the instructor console is mainly used to control and set the flight environment, flight subjects, etc. ; The flight principle demonstration device includes real-time force and torque display, as well as storage and playback of control and helicopter response curves; it is characterized in that the helicopter simulation cockpit 1 is connected to the visual device 2 through the main control and communication device 4 and outputs the cockpit instruments and visual flight information to the visual device 2, the instructor console 3 is connected to the helicopter simulation cockpit 1 through the main control and communication device 4 to realize the control of the helicopter simulation cockpit 1 and related instruments, and the flight principle demonstration device 5 is connected to the helicopter simulation cockpit 1 through the main control and communication device 4 to realize the storage of information such as force and torque display and helicopter response after the helicopter simulation cockpit 1 is operated;

[0029] The trainee sits in the helicopter simulation cockpit 1, adjusts the position through the 1 guide rail 05-1 of the simulation seat 105, and the instructor turns on the visual device 2, the instructor console 3 and the flight principle demonstration device 5. After the instructor selects the flight simulation course, the project is sent to the entire system device through the main control and communication device 4;

[0030] After entering the designated course, the trainee controls the flight attitude of the aircraft through the joystick control system 104-1, the pedal control system 104-2, and the collective distance control system 104-3 in the control system component 104. During the entire flight process, the trainee pays attention to the flight parameters such as the angle of attack and speed in real time through the central instrument panel 103 of the cockpit. The visual generation device 201 outputs the flight status of the aircraft of the simulation course to the visual display device 202 in the form of intuitive animation, so that the trainee can pay attention to the real-time flight status.

[0031] During the simulated flight, trainees can not only visually see the flight parameters and flight status, but also push (pull) the joystick control system 104-1 to drive the crank 104-1-A, spring tube 104-1-B and lateral and longitudinal installed damping parts to provide the operating lever with the same control damping force as the real aircraft. Touching the button switch, azimuth switch and gravity switch of the joystick control system 104-1 provides a realistic control feeling, and the left and right pedal control system 104-2, plus and minus total pitch control system 104-3 and other operations provide a more realistic experience of actual flight.
