Development of Electromechanical Actuators and Electronic control Units for Flight Control Systems

Descripción del proyecto

Nuevos sistemas de accionamiento para lograr aeronaves más ligeras y ecológicas

El desarrollo de sistemas de accionadores electromecánicos (EMA, por sus siglas en inglés) contribuirá a reducir el peso de las aeronaves, el combustible y los costes de mantenimiento y producción. Por ello, es necesario sustituir los accionadores electrohidrostáticos convencionales por EMA. El equipo del proyecto EMA4FLIGHT, financiado con fondos europeos, tiene como objetivo diseñar, desarrollar, fabricar y validar los EMA y sus unidades de control electrónico específicas para el accionamiento de las superficies de control de vuelo de alerones y deflectores, así como para el accionamiento de las superficies de las aletas y los «flap». La innovadora arquitectura de los motores eléctricos y los husillos de bolas, las estrategias de control avanzadas y las funciones inteligentes de seguridad, diagnóstico y mantenimiento se utilizarán para mejorar los subsistemas pertinentes.

Objetivo

Nowadays, there is a trend towards the More-Electric Aircraft (MEA) concept. MEA would replace the secondary aircraft power systems (electric, hydraulic and pneumatic) with a globally optimized electrical system. However, the architecture of the electric system must be carefully selected to optimize the whole aircraft. Actual research in MEA technology is focused on new advances in power electronics, fault-tolerant electric machines, digital control, electro-mechanical actuators and communications. Modern technologies involved in MEA are being taken in two different paths: i) elimination of bleed-air systems and hydraulic engines with further improvements in electrical power generation capability. It requires changes in both electrical generation and distribution network, and ii) replacement of hydraulics actuators with electro-mechanical actuators with the same level of safety and reliability, reducing weight, fuel usage, maintenance and production costs.
Several studies have been recently carried out emphasizing the interest on the replacement of the traditional electro-hydrostatic actuators used in flight control surfaces by electro-mechanical actuators (EMAs). The reasons for such a choice are: weight and maintenance reduction, elimination of pipes vibration problems, increase of reliability, increase of the system performance and pressure losses thanks to the absence of valves.
The EMA4FLIGHT project will design, manufacture and tune innovative electro-mechanical actuator sub-systems for aileron/spoiler and winglet/flap-tab flight control surfaces, with clearance for flight. The designed sub-systems will be improved by electric motor and ballscrew innovative architecture, advanced control strategies and smart safety, diagnostic and maintenance functions.
