Abstract

The paper considers rotational catapults to launch flying vehicles (FV). Their mathematical descriptions with calculation formulas are given. Rotational catapults are compared with conventional steam and hydraulic devices on the accumulated potential and kinetic energy, power, efficiency, work and the capacity of electrical accumulators. Rotational catapults advantages and disadvantages are analyzed. Ways to fix the existing disadvantages are described. Formulas for calculation of power capabilities of the catapult energy sources are given. Rotational catapults basic performance characteristics are shown, their structural units are depicted. Catapults application in the state-of-the-art systems and devices for unmanned and piloted FV launching are analyzed.
