“The AMULET project addresses the development of unit control, energy management and monitoring unit for up to four actuators, intended for the controlled deformation of a functional prototype of a wing with a morphing leading edge. This concept is very new and aims to replace the current rigid deployable surfaces (flaps, slats, etc.) of optimization of the shape of the wing, by wings that adapt their morphology adapting to different flight conditions.

For decades, aeronautical morphing structures were not applied to commercial airplanes, while the deployment of rigid surfaces was widely used to optimize the performance of the aircraft with different flight regimes.

Discontinuities and gaps between moving surfaces lead to a worsening of aerodynamic efficiency and an increase in noise emission. Therefore, a deformable surface could solve the aforementioned problems, but at the same time it should be able to withstand external aerodynamic loads without significant deformations to guarantee the state of the designed target.

The main drawback of the design of “morphing” structures is the complexity required by structural frameworks and control systems. In fact, due to the need for feedback control of each individual actuator and the need to control several actuators in a specific application (eg, the morphing leading edge), higher order control structures are required.

The main objective is to develop, manufacture and qualify a compact control device for the Morphing Leadin Edge application, thus allowing the replacement of current slats with a deformable surface.

The benefits achieved and technological innovation are the basis of the trends of the new paradigm and scientific research, within the Aeronautical Industry

The optimization of aircraft is unequivocal;

  • Acoustic emission reduction
  • Optimization of dimensions and weight
  • General friction reduction
  • Performance efficiency improvement
  • Health surveillance through innovative strategies

The second objective is to carry out testing and integration tests in the environment, thus achieving:

  • Validation of the control device with the functional and operational requirements of the t.r.a. (at system level)
  • Verification of the correct integration with the balance one actuators

Features and design improvements

Embedded ECU capable of simultaneously controlling up to four electro-mechanical actuators.

  • Modular design, separate designs for control and power module
  • Health Monitoring intelligent power and capacity management system
  • Operation over a wide range of voltages
  • Ethernet, USB, Serial & CAN communication interfaces
