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

Periodic Reporting for period 2 - EMA4FLIGHT (Development of Electromechanical Actuators and Electronic control Units for Flight Control Systems)

Reporting period: 2018-02-01 to 2019-03-31

EMA4FLIGHT Project aims to design, develop, manufacture and validate optimized and reliable innovative Electro-Mechanical Actuators (EMAs), and their dedicated Electronic Control Units (ECUs) for aileron/spoiler flight control surfaces actuation and for winglet/flap-tab surfaces actuation. These Motor, ballscrew and mechanical parts/ECU sub-systems will be, in the future, boarded onto FTB2 Regional Aircraft IADP for their in-flight validation. The development of electromechanical actuation systems for aircrafts will help to achieve the objectives set by ACARE for the aeronautics industry as they will reduce the weight of the aircrafts enabling a consumption reduction. The designed sub-systems will be improved by electric motor and ballscrew innovative architecture, advanced control strategies and smart safety, diagnostic and maintenance functions.
During the first and second periods of the Project the most relevant results of the developments are:
• Aileron/Spoiler sub-system:
- Preliminary ECU, Motor and Ballscrew design.
- ECU hardware software plans and standards for RTCA-DO254 and RTCA-DO178.
- Back up SHA under manufacturing.
- HW ECU, Motor and Ballscrew ATP definition.
- Motor and Ballscrew QTP definition.
- Critical HW ECU, Motor and Ballscrew design (CDR).
- ECU hardware software plans and standards for RTCA-DO254 and RTCA-DO178.
- ECU SW High Level Requirements specifications, architectural design and detailed external interfaces.
- SW ECU design status review including industrialization information.
- Mosto f the Manufacturing routes developed and agreed with the TM.
- SHA Aileron units delivered to TM.
- Feel Units delivered to TM.
• Winglet/Flap tab sub-system:
- ECU preliminary design.
- ECU plans and standards for RTCA-DO254.
- Flab tab EMA’s selected.
- ECU critical design.
- 2 ECU Functional Prototypes Manufacturing.
- EMA/ ECU integration.
- EMA/ ECU Functional Tests execute.
The new actuation systems will help the reduction of emissions of the aircrafts due to the reduction on the overall weight of the aircraft, therefore, contributing to reach the goals set by ACARE for the aeronautic industry in 2050. The developed ECU, motor and ballscrews for aileron spoiler subsystems and the flap tab and winglet ECU will contribute to weight savings and therefore, to a greener aviation.
