The All-Electric Aircraft is a major target for the next generation of aircraft to lower consumption of non-propulsive power and thus fuel burn. To eliminate hydraulic circuits, pumps and reservoirs, Electro Mechanical Actuators (EMA) are mandatory but now need to meet cost, reliability and weight requirements from the airframers.ACTUATION2015 aims to develop and validate a common set of standard ...

...rafts reduction of mass and power consumption are a major issue. On the other hand, in case of mechanisms for Solar Arrays or antennas big masses have to be moved and kept in position for long times. Harmonic Drives would fulfil the requirements: high gear ratios enable the use of small actuator motors (low mass and power), they provide high stiffness and high precision even at very low speeds.How ...
