The ASTIB project, started in 2018 in collaboration with Leonardo, aims to contribute to the generation of new technological products to be implemented in future Green Regional Aircraft (GRA).

The main aim of the project is to support the improvement of the Technological Readiness Level up to TRL 5-6 for a considerable number of electronic devices considered of critical importance for the future GRA.

Specifically, the project involves the realisation of:

- Electromechanical actuators (EMAs) with their associated electronic control units (ECUs) for specific flight control surfaces;
- Winglet and Wigtip with morphing capability;
- Electric actuation of one main and one front carriage;
- Reliable prognostics and health management functions for electromechanical actuators;
- An advanced test bed for multifunctional integration, verification and validation (‘Iron Bird’);
- Development of a validation platform for health monitoring;
- Tools for evaluating the benefits of an integrated health monitoring platform;

Italsystem is responsible for the design and SW development for the Electronic Control Unit (ECU) of WINGTIP and WINGLET. The movement of these particular surfaces takes place thanks to advanced electromechanical actuators with local digital control units and a central flight control computer that, on board the aircraft, acts as a supervisor, verifying and adjusting in real time the performance of the active aerodynamic load control and distribution system (Load Control & Alleviation) to optimise aircraft attitude, performance and fuel consumption in the various phases of flight.

Specifically, the WingTip is equipped with a movable part of about 80 centimetres in height, capable of a maximum rotation of ±15 degrees (photo 2), while the WingLet is a vertical end flap with a height of about 1 metre and consists of two independent movable parts, each with a maximum rotation of between +5 degrees and -15 degrees.
