Problems solved by technology

The IMU needs to work at a specific operating temperature in order to maintain the accuracy and stability of the measurement. Therefore, to achieve this purpose, a heating device is installed around the IMU to adjust the temperature of the IMU. However, the existing heating device and the IMU produce physical Contact and pre-pressure, when the temperature increases, the pre-pressure on the surface of the IMU will also increase, resulting in inaccuracy and instability in the control of moving objects, especially the inaccuracy of the IMU in the aircraft will cause the aircraft to "drop height" Phenomena that have a greater impact on the performance of the aircraft
At the same time, the heat of the heating device will be directly or indirectly dissipated to the outside world, so that the initial heating time of the IMU is too long, or the moving object starts to work when it is not heated to the standard operating temperature of the IMU, which may easily cause control problems for the moving object

Abstract

The invention relates to an inertial measurement module, a flight control inertial measurement assembly and an aircraft, and the inertial measurement module comprises an inertial measurement unit which is used for measuring the inertial parameters of a moving object; an electric heating piece, which is arranged side by side with the inertia measurement unit at an interval, and is used for exchanging heat with the inertia measurement unit; a packaging structure which is used for packaging the inertial measurement unit and the electric heating piece inside; and a heat-conducting medium which isfilled in a gap between the inertial measurement unit and the electric heating piece and does not cover the top surface of the inertial measurement unit. The working temperature of the inertial measurement unit in the inertial measurement module can be maintained in an optimal state, and the pressure borne by the inertial measurement unit is small, so that the measurement accuracy and reliabilityof the inertial measurement unit are improved.

Description

Technical field[0001]The present disclosure relates to the technical field of inertial measurement, and in particular, to an inertial measurement module, a flight control inertial measurement component, and an aircraft.Background technique[0002]An Inertial Measurement Unit (IMU) is a device that measures the three-axis attitude angle (or angular velocity) and acceleration of a moving object during the movement. The conventional IMU includes three single-axis accelerometers and three single-axis gyroscopes: the accelerometer detects the acceleration signal of the aircraft in the independent three-axis of the carrier coordinate system, and the gyroscope detects the angular velocity signal of the carrier relative to the navigation coordinate system. By measuring the angular velocity and acceleration of an object in three-dimensional space, the aircraft's motion attitude can be calculated, which plays a central role in flight control. The IMU needs to work at a specific working temperat...
