Instruments such as a horizon sensor, a magnetic compass, a sideslip sensor and the like are mainly used for indicating flight attitude and heading information of an airplane, and most of the instruments comprise a gyroscope, so that the instruments belong to gyroscope instruments. Because the gyroscope has the axis-fixing property, the attitude angle of the airplane can be conveniently measured, and therefore the horizon sensor is mainly manufactured by utilizing the axis-fixing property of the gyroscope. The design and manufacture of the sideslip instrument mainly depend on the precession principle. The core component of the horizon sensor is a gyroscope inside the horizon sensor, and the horizon sensor is modified by a torquer and a pendulum component in the horizon sensor and is used for measuring the indicators of the pitch attitude angle and the roll angle of an object attached to the gyroscope. The course gyro, the horizon sensor and the sideslip sensor jointly form an attitude indicating system of the airplane. The simulator does not move in the air, the actual gyroscope cannot play the due role, a horizon finder movement mathematical model can be designed by referring to an inertia benchmark program and a gyroscope principle, flight parameters are input into the model as input quantities, attitude and heading parameters including the position, the angle and the like of an aircraft can be calculated, and the attitude and heading instruments are driven by the parameters. The current yaw angle of the aircraft can be obtained by resolving according to a kinetic equation of the aircraft, the current yaw angle is corrected according to longitude and latitude coordinates and altitude information to obtain the true course of the aircraft, the true course which is just obtained is corrected according to magnetic differences of different regions to obtain a magnetic yaw angle, and the magnetic yaw angle is output to a corresponding course instrument.

The control system includes: the upper computer is provided with a flight simulation system; and the CAN bus is respectively connected with the upper computer, the instrument module, the control module, the display module, the communication module and the sound module.

The instrument module is completely the same as a real airplane and provides various flight state information for pilots.

The display module is used for generating various external scenes in the operation process of the airplane and providing real visual perception.

The sound module is used for simulating the sound inside and outside the cabin of real flight and providing vivid sound effect.

The manipulation module is used for providing real manipulation force feeling.

The flight simulation system is the brain of the flight simulation training device, and realizes the resolving of flight actions and the control of each module.

The simulated cockpit 7 carries various simulation devices, the same size as the real cockpit.

The lateral movement means 2, the vertical movement means 3, the horizontal turning means 4, the pitching means 5 and the rotating means are able to simulate the feel of movement of yaw, pitch, roll, lateral, longitudinal and heave during movement of the aircraft, as well as to simulate overload.

The transverse moving device 2 and the vertical moving device 3 are both provided with position control switches for controlling the maximum moving position.

The transverse screw rod is arranged along an X axis, and the vertical screw rod is arranged along a Z axis. The lead screw can adopt a lead screw with a large lead, and all motors adopt servo motors.

The core components of the flight simulation training device comprise a multi-axis motion controller besides a computer for calculating and analyzing real-time data and a flight simulation system. The multi-axis motion controller is used for receiving each driving signal sent by the computer in real time, inputting the driving signal into each servo driver and receiving the feedback of the encoder in the servo motor.

The flight simulation training device has the advantages of high response speed, compact structure, large starting torque, small inertia, high control precision and sensitivity, simple maintenance and simpler control.

During flight simulation, overload simulation can be realized through the transverse screw rod and the vertical screw rod, the screw rod is stable and reliable in transmission, and the linear speed is high; during flight action simulation, the horizontal rotating device 4 rotates around a Z axis, the pitching device 5 rotates around an X axis, and the rotating device rotates around a Y axis; and further, the simulation of the flight action and the overload simulation are realized while the flight action is simulated.

The transverse screw rod is long, and is mainly used for realizing long-time overload simulation. The transverse screw rod can realize overload simulation by reciprocating the transverse sliding table 21. For safety reasons the vertical screw is short, the overload simulation time provided is very short.

The operating system performs transverse movement, vertical movement and rotation around X, Y and a Z axis according to the control of a pilot, and controls the five servo motors to realize the simulation of action and overload, so that the action simulation and the overload simulation are more real, and the problems that an existing continuous load flight simulator in a centrifugal mode can generate an interference angle which is not matched with a simulated airplane in the overload simulation process, the angular motion sensed by the vestibular function of the pilot is not matched with the angular motion sensed by vision due to the existence of the interference angle, the pilot is dizzy, the input control and output feedback of the pilot are not consistent with the simulated airplane and the like are solved.

The pilot controls the control module in the simulation cockpit 7, the control module sends signals to a flight simulation system installed on an upper computer through a CAN bus, the flight simulation system obtains flight state information and control instructions of a flight simulation training device after resolving, the control instructions are transmitted to a transverse motor, a vertical motor, a rotary motor 43, a pitching motor and a rotary motor through the CAN bus, the flight simulation training device generates corresponding movement, the flight state is sent to an instrument module, a display module and a sound module through the CAN bus, and the pilot is provided with real overload, movement, vision and auditory feelings. The angular motion information sensed by the trainee of the flight simulation training device is matched with the angular motion information sensed by the pilot flying the airplane, so that the problem of mismatching between the angular motion sensing and the visual sensing of the trainee of the continuous load flight simulator is effectively solved, and the fidelity of the flight simulation training device is improved.

The flight simulation training device realizes flight simulation in a centralized control mode.

The flight simulation training device can perform a simulation test of large pitching motion. Large pitch movements are mainly related to changes in pitch angle, and roll and yaw angles remain unchanged during the movement. The flight simulation training device keeps a flat flying state at an initial position, then gradually increases the pitch angle, decreases the pitch angle after reaching a certain angle, and finally recovers to the flat flying state.

The flight action of the fighter has strong maneuverability and agility, which is reflected in the wide range change and the rapid conversion of the flight attitude, and the complexity and the intensity of the modern air combat are reflected. The most notable of these flying maneuvers are maneuvered by cobras first created by the well-known pilot, poga and jeff.

The cobra maneuver is an over-stall flying maneuver, and in the flying process, a pilot quickly pulls a control lever backwards to enable the nose of the airplane to face upwards to 110-120 degrees, at the moment, the airplane is in a flat flying state with the tail at the front and the nose at the back, and then pushes the control lever forwards to press the nose, so that the airplane is restored to the original horizontal state. During the cobra maneuver, the entering speed of the airplane is about 425km/h, the airplane decelerates at a speed exceeding 110km/h until the speed is reduced to 148km/h, the airplane is overloaded by 3.5g to 4g in the whole process, and the flying height of the airplane is almost unchanged.

Cobra maneuvers are not only an elegant flight maneuver, but also an effective tactical approach to attack and defense. For example, in air combat using omnidirectional missiles, the enemy plane can be attacked in a wider range by using the missed maneuver, so that more missiles launching opportunities are provided for pilots; when the airplane is subjected to pursuit of an enemy airplane, the motor-driven rapid deceleration of the cobra can be utilized, so that the enemy airplane rushes to the front of the airplane, and a favorable attack position is created for the airplane. Of course, the implementation of such a large pitch delinquent maneuver is not only related to the tactical performance of the fighter, but is also indistinguishable from the pilot's driving technique. Because the traditional flight simulator only has a rotating angle range of plus or minus 35 degrees, the flight action with large pitching can not be finished, and the flight simulation training device provided by the invention can simulate the cobra maneuver through the transverse moving device 2, the vertical moving device 3 and the pitching device 5. The lateral movement means 2 provide a forward deceleration movement and overload, the vertical means provide an upward climb and overload, and the pitch means 5 provide an upward tip of the head.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive step, which shall fall within the scope of the appended claims.
