Most of morphing aircrafts control the flight attitude by the deformation of aircraft wing, however morphing UAV is not limited to the deformation of the wing. This paper studies cyclic variable pitch propeller system which can generate control torque. According to mathematical model of cyclic variable pitch propeller based on propeller blade element theory, the study analyzes the principle and researches...
Capacitor banks are used to provide a high pulsed power in traditional electromagnetic launch systems, but the large volume of these capacitors greatly limits the movability of the system; meanwhile, more and more applications require a system with significantly higher energy storage density. Rotation machines that can quickly convert rotational kinetic energy into high-current electrical energy have...
In order to demonstrate the wind turbine in the laboratory, this paper first analyzed the operation principles, the power and torque characteristics of the wind turbine and direct current (DC) motor, then it investigated the operation characteristics of the wind turbine in contrast to those of the DC motor. The torque imitation scheme was provided, which imitates the torque characteristics of wind...
