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.
ACTUATION 2015 aims to develop and validate a common set of standardised, modular and scalable EMA resources for all actuators (flight control, high lift, main landing gear, door, thrust reverser) and all types of aircraft (business/regional/commercial airplanes and helicopters).
Compared to the A320, ACTUATION 2015 will reduce the overall Life Cycle Costs of actuators by 30%, improve reliability by 30% and reduce aircraft weight by 500kg. The project relies on recent advances made in EU and national projects to integrate the required technologies (solid state power distribution, power electronics, operation in harsh conditions, jam tolerant EMA) to overcome the current barriers to EMA and mature EMA technologies to TRL 5.
Standardising EMA modules (motors, power drive electronics, mechanics, sensing) will be a key enabler to succeed in achieving cost objectives and developing the supply chain. Standardisation will start during the project with the support of a standardisation body (CEN).
The technical approach will be to gather detailed airframes requirements, specify a set of standard modules and develop prototypes for assessment at component and actuator level through rig tests and the virtual validation of modules. In parallel, a unified EMA design process supported by standard methods and tools will also be developed. ACTUATION 2015 will complement existing projects, notably CLEAN SKY SGO with an EMA solution, and pave the way towards the ACARE 2020 All-Electric Aircraft.
ACTUATION 2015 is coordinated by GOODRICH ACTUATION SYSTEMS SAS (F) and involves 53 partners from all over Europe.
