Research On Terminal-sensitive Ammunition Without Parachute Motion Parameters Measurement Technology And Experimental Methods

To enable Terminal-sensitive projectile without parachute to reach steady state scan status, it must be accurate to get Terminal-sensitive projectile without parachute drop during attitude parameters to provide a reliable basis for the design and improvement. For Terminal-sensitive projectile speed phenomena exist without parachute larger scanning angle instability, excessive speed, etc. In the steady drop scanning stage. Terminal-sensitive projectile without parachute scan attitude measurement system for Terminal-sensitive projectile without parachute development has a vital significance.In order to solve the Terminal-sensitive projectile without parachute, scan attitude parameters measured steady-state problem, this paper based on Terminal-sensitive projectile without parachute, stable scanning motion characteristics, the establishment of Terminal-sensitive projectile without parachute, the motion model; using quaternions rotation vector to achieve a Terminal-sensitive projectile without parachute.The paper-based three-axis magnetometer, three-axis MEMS gyroscope and three-axis MEMS accelerometer measurement system was a combination of experimental verification. Static calibration tests, Terminal-sensitive projectile without parachute turntable semi-physical experiments and high-altitude launch tests to determine the attitude parameters of static error, get a Terminal-sensitive projectile without parachute scan angle variation and estimates of Terminal-sensitive projectile without parachute scan attitude parameters.
