Description

Technical Field

[0001] This utility model belongs to the field of helicopter simulator research and development, specifically relating to a magnetic compass suitable for flight simulators. Background Technology

[0002] The market for flight simulators is expanding rapidly. In this environment, to achieve higher simulation fidelity, we have studied the functions of real helicopter electronic components. Existing ground flight simulators mostly use instruments from real aircraft, which are difficult to match with flight simulators and are also costly. Therefore, it is necessary to propose a magnetic compass suitable for flight simulators to address these issues.

[0003] A magnetic compass is an instrument used to indicate the flight direction or bearing of aircraft such as helicopters, and it is of great significance for the correct operation of helicopters in training and combat missions. Its working principle is based on the interaction between the Earth's magnetic field and the magnets inside the instrument. The Earth's magnetic poles are located near the geographic poles, but not adjacent to them. In the Northern Hemisphere, they exhibit south magnetism, while in the Southern Hemisphere, they exhibit north magnetism. The north end of the magnetic needle points north, meaning the north magnetic pole (with south magnetism) is considered to be near the geographic North Pole, and the south magnetic pole (with north magnetism) is considered to be near the geographic South Pole. The angle between the geographic meridian and the magnetic meridian is called magnetic declination (or magnetic difference).

[0004] The magnetic compass is mounted in front of the pilots in the front and rear cockpits as an emergency instrument. Based on the Earth's magnetic properties, it provides auxiliary guidance during flight, indicating the aircraft's magnetic heading. Since simulators do not represent real flight motion, their range of motion is limited, and airborne magnetic compasses are susceptible to electromagnetic influences and interference. Therefore, using an airborne magnetic compass cannot achieve the same magnetic heading indication as in simulated flight. Summary of the Invention

[0005] This application provides a magnetic compass suitable for flight simulators, which can solve the problem that airborne magnetic compasses cannot provide magnetic heading indication for simulated flight.

[0006] Technical solution: This application provides a magnetic compass suitable for flight simulators, including a base (1), a retaining ring (2), a main control board (3), a pressure cover (4), a mounting block (5), a gimbal motor (6), a dial (7), a lighting board (8), a compass cylinder (9), a glass cover (10), decorative parts (11), and a mounting bracket (12), wherein:

[0007] The base (1) has screw holes at both ends, which are connected to the retaining ring (2) by screws; the retaining ring (2) has a through hole, which is connected to the mounting bracket (12) by bolts; the main control board (3) has at least two screw holes evenly distributed, which are connected to the pressure cover (4) and the mounting block (5) by screws; the pressure cover (4) consists of two symmetrical structural parts, which are connected to the mounting block (5) by at least two screws; the mounting block (5) consists of two symmetrical structural parts, which are connected to the gimbal motor (6) by at least two screws; the gimbal motor (6) is a brushless motor, which is connected to the dial (7) by at least two screws; the dial (7) is placed on the lighting plate (8); the lighting plate (8) is installed at the bottom of the compass cylinder (9) by at least two screws; the glass cover (10) is installed on the inner wall of the compass cylinder (9) by at least two screws; the decorative part (11) is a plastic decorative part; the mounting bracket (12) installs the magnetic compass in the simulator cabin by at least two screws.

[0008] Specifically, the maximum power of the gimbal motor (6) is no more than 20W and the maximum speed is no more than 600RPM.

[0009] Specifically, the main control board (3) receives geographical and azimuth information transmitted from the simulator's avionics computer and drives the gimbal motor (6) to rotate. The voltage output by the main control board (3) is no greater than 16V and the current is no greater than 1.3A.

[0010] Specifically, the dial (7) is used to display the magnetic heading angle, with a short scale line every 5°, a medium scale line every 10°, and a long scale line every 30°, and the magnetic heading angle is marked with numbers.

[0011] Specifically, the magnetic compass body is mounted on the mounting bracket (12) with a single bolt, and the angle is adjusted within a range of 150° around the mounting axis of the simulator cabin.

[0012] Specifically, the magnetic compass has a magnetic heading angle indication range of 0°-360°; the magnetic compass response time is less than 5ms, and the indication error is less than ±2°.

[0013] In summary, this invention provides a magnetic compass suitable for flight simulators. The magnetic compass's appearance and dimensions are consistent with the actual airborne component, ensuring its indicating rotation and sway characteristics are identical to those during airborne operation. The modified magnetic compass can communicate with the avionics computer and receive instructions from the computer to indicate magnetic heading. When the magnetic compass is not powered on or has not resolved the correct magnetic heading, it indicates 0° (N); when powered on and the correct magnetic heading is resolved, it indicates the corresponding magnetic heading angle. The magnetic compass has a response time of less than 5ms and an indication error of less than ±2°, effectively replicating the function of a real airborne magnetic compass on a helicopter and greatly enhancing the realism of the simulator's flight simulation.
