Description: I set out the problems in the flight of unmanned aircraft vehicles using catapults to drive forward reaction. These features work ground catapults telescopic transmission. The scheme workflow that implements a minimal regression traction. The methodology of calculating the characteristics of an actuator based on the standardization of the work expand. We describe the complex conjugate physical and mathematical model of pneumatic catapult. The results of calculation of ground launching device in the form of color maps of physical fields and the main integral characteristics.
Keywords: ground catapult, dynamic characteristics, telescopic transmission, work rate
