The data test of aircraft launching and flight stage is an important research direction at present.As a loadable data acquisition device,the data recorder has important research value.Aiming at the data acquisition of small aircraft,a microelectronic mechanical system(MEMS)sensor data recorder with small volume,low power consumption,high performance and high anti-overload ability was proposed.It can measure the data of triaxial angular velocity,acceleration and magnetic field synchronously.Data calculation and experimental test results show that the total volume of the recorder is 22.4 cm3,and the power consumption in the working state is only 0.68 W.Through the anti-overload process,the anti-overload capability of the system reaches 18 000g,which realizes the characteristic requirements for small volume,low power consumption and high anti-overload capability.Labview software was used to measure the magnetic field data and analyze the error.The obtained maximum linearity error is only-1.14%,which meets the index requirement that the linearity error of HMC1053 triaxial magnetic sensor is better than±1.8%,and can realize the data acquisition during the launching and flight of small aircraft and has high feasibility.
