Design And Realization Of The Store Testing And Measuring System Of The Over-loaded And The Attitude Paramete About The Mini-Flight Body

Getting information of missile flying attitude is always one of the key characters during the study about accurate guidance weapon. The attitude measurement of flight body provides the important foundation for verifying and optimizing the design. Measurement also plays an important role in finalizing the design, checking and accepting the flight body.This topic is a part of the national natural science hosted by Professor Ren Yongfeng. The name of the national natural science is the research on the active laser-guided exploration technology about minitature high-speed movement body(Project Numbers: 60871041). This paper studied the store testing and measuring system of the over-loaded and the attitude paramete about the mini-flight body more systematicly and comprehensive.The first tast of this topic is to establish a launch platform with 35m/s launching speed. The platform provided a reliable test platform for study about the launching over-loaded and the attitude paramete. Secondly, the store testing and measuring system is designed to test and record the launching over-loaded, speed and attitude paramete on the flight. Finally, the curves of the launching over-loaded and flight attitude parameter have been got through the processing of the computer software. The curves provided the reference for the study of the projectile deflection and other follow-up work.The store testing and measuring system is used to test and record the launching over-loaded and flight data. It can be divided into two parts: the test and record device in the missile and the speed measurement equipment on the ground. The first part tests and records the variety of the data on the flight. After recycling, the data in the store testing and measuring system will be read through the read box. Finally, the curves of the over-loaded and flight attitude parameter will be got by the compute software. The initial speed of launching will be calculated from the over-load curve. The speed measurement equipment on the ground can measure the initial speed of launching directly. The result compared with the above calculated initial speed to verify the over-loaded curve tested by the test and record device in the missile.
