BENCH FOR SIMULATING THE LAUNCH OF AN AIRCRAFT ROCKET Russian patent published in 2022 - IPC F41F3/06 

FIELD: rocket technology.

SUBSTANCE: invention relates to the field of rocket technology, in particular to devices for the installation and launch of aircraft missiles, namely to test benches for measuring the forces arising from the movement, fixation and descent of aircraft missiles from the guiding aircraft launchers. The bench for simulating the launch of an aircraft rocket consists of a spatial frame with an aircraft launcher fixed in it (hereinafter referred to as the AL) and longitudinal guides designed to move the carriage support rollers along them using a power drive. On the carriage there is the overall mass layout (hereinafter, OML) of the rocket. At the initial stage of the bench operation, during the forced rotation of the axes of the support rollers, the carriage moves with its internal threaded surfaces along the external threaded surfaces of these axes. This carriage movement ensures the correct installation of the longitudinal axis of the OML relative to the longitudinal axis of symmetry of the guides for the descent of the AL missiles. The bench is equipped with a support and lifting mechanism for vertical movement of the OML, made in the form of eccentrics installed in the OML on two rotary axes, levers with a connecting rod, stops and tides mounted on a carriage with grooves. The eccentrics are installed in the corresponding ridge slots. Due to the movement of the connecting rod with levers and the rotation of the eccentrics in the ridge slots, a vertical plane-parallel arc-shaped movement of the OML occurs and the entry of the lugs into the receiving windows of the guides for the descent of the AL missiles, followed by the installation of the lugs on these guides. The force from the power drive rod through the carriage, load cell and bracket is transmitted to the OML. In the process of moving the OML along the guides for the descent of the AL missiles, there is a continuous measurement of the forces arising along the entire path of moving the OML lugs along the guides for the descent of the AL missiles, as well as the actuation efforts of the locking device for fixing the rocket in the AL.

EFFECT: increase in the accuracy of measuring the forces that occur along the entire path of moving the OML along the guides for the descent of the AL missiles, as well as the actuation forces of the locking device for fixing the rocket in the AL.
