摘要

The invention relates to the field of devices for ground testing of aircraft, in particular to a stand for testing copra tubular helicopter skid landing gear that are conducted to simulate the helicopter landing. Stand for copra test skid landing gear of the helicopter comprises a mass-inertia layout helicopter (MIMV), the device for lifting and dumping layout portal for fastening devices for lifting and dumping a given layout, a horizontal landing platform, consisting of four tenzoplatform, accelerometers, mounted in the center of mass mass-inertia layout and in the front and rear springs, devices for measuring displacements consoles springs skid-chassis relative to the inertial mass and layout for measuring moved I was the center of mass relative to the layout of the landing platform. A feature of the stand is the ability to simulate two landing cases: the case of vertical landing and landing with a horizontal translational speed. The identity of the full-scale vertical landing and coconut relief provided by the equality of effort perceived springs consoles and work absorbed by chassis for the navigation and landing drop-hammer reset. The equality is achieved in that the drop-hammer resetting the mass and the position of the center of mass layout changed in comparison with the mass and the position of the center of mass of the real helicopter. Values ​​mixing center of mass and weight reduction MIMV defined by given relationships. The stand allows you to play the second landing a blow that always takes place at the rough landing of the helicopter freewheel.; The great advantage of the stand is the lack of horizontal translational motion MIMV at reset, which can significantly reduce the size of the stand and, therefore, significantly reduce the demand for manufacturing space, simplify the design of the stand, to reduce the time required to prepare for the test.
