Research and Application of Statically Determinate Support and Restraint Technology for Static Test on Large Aircraft

The support and restraint technology for Static test on full scale aircraft was very important, which has tremendous influence on the goals and successful completion of the test. The design method of support and restraint scheme for Static test on full scale aircraft was proposed, and the theory model of statically determinate support and restraint was established too. According to the achievement above-mentioned, an statically determinate support and restraint system was designed and manufactured, which was used on the static test of one aircraft successfully. The statically determinate support and restraint system was steady in the test, which can show the situation of loading. The results of test indicates that The statically determinate support and restraint system was logical and scientific, which can satisfied the require of test and offered reference for similar test.
