Description
Technical field
The utility model relates to parachute air-drop technical field, particularly relates to the multidirectional proving installation of the dynamic deploying force of a kind of escape parachute.
Background technology
Along with improving constantly of new fighter performance, harsher index request be it is also proposed to escape parachute performance index, as general in upland plain, terminal-velocity is not more than 5.43m/s, deployment time is not more than 2.3s etc.In order to can the performance index of comprehensive assessment escape parachute, during airdrop test, stricter requirement be it is also proposed to method of testing.The method of testing of current escape parachute deploying force handles in left and right to bring each series connection 1 pulling force sensor, the shortcoming of this method of testing is: can only to deploying force make a concerted effort test, truly can not reflect stressing conditions during the actual parachute-opening of parachute, and Parachute Opening Process is the comprehensive force and moment in a complicated direction, space three.In order to can accurately study Parachute Opening power and analyze the attitude of dummy in opening process.Need by testing the force and moment in dummy three directions, thus calculate the angle between dummy and deploying force three durection components, can better analyze the stressing conditions of parachute air-drop process.
Along with the development of drop-test technology, in order to performance index when comprehensive assessment Novel lifesaving umbrella drops, method of testing for deploying force proposes stricter requirement, as: deploying force is more true and accurate, needs the component testing out deploying force three directions.In order to can accurately study Parachute Opening power and analyze the attitude of dummy in opening process, need by testing the force and moment in dummy three directions, and then calculate the angle between dummy and deploying force three durection components.Traditional deploying force proving installation can not meet the demand of test.
Utility model content
The technical problems to be solved in the utility model is for when measuring the stressing conditions of dynamic parachute-opening in prior art, only measure the defect that every root handles the pulling force brought, there is provided a kind of can Measurement accuracy dynamic parachute-opening time stressing conditions, and it is carried out to the multidirectional proving installation of the dynamic deploying force of escape parachute of decomposition computation.
The utility model solves the technical scheme that its technical matters adopts:
The utility model provides the dynamic deploying force of a kind of escape parachute multidirectional proving installation, comprises crossover sub, balance protective sleeve, balance main body and balance pedestal;
Described balance main body by key, carve and be connected with balance pedestal;
Described crossover sub is connected with described balance main body with hexagon socket head cap screw by key;
Described balance pedestal is connected with dummy's backboard by 2 cylindrical pin with internal threads, 4 hexagon socket head cap screws;
