DAVYD

Development of innovative technologies for control surfaces and landing gear actuation

Research

The main objective of the project DAVYD is to reduce the impact of flight vehicles on the environment both in terms of pollution and noise emissions according to the specialization areas (Aerospace), defined by PNR 2015-2020 and SNSI, and ACARE 2050 goals. The consortium DAVYD focuses on two aircraft components where the application of innovative technologies will allow reducing noise and pollution. The two systems of interest are the electromechanical landing gear system and the control surfaces of an aircraft/fast rotorcraft. In both cases, the idea is to reduce the vehicle CO2 and NOx emissions by modifying the components weight and, then, achieve the noise reduction.

Simple adaptive wing-aileron flutter suppression system

In this work a simple adaptive flutter suppression system is designed in order to increase the operative speed range of a wing-aileron aeroelastic plant. The equivalent beam finite element based aeroelastic modeling of a wing equipped with a trailing edge aileron in incompressible flow is presented and its state space representation is provided. The almost strictly passivity of the plant is assured by means of a parallel feed-forward compensator implementation and the invariant controller parameters are tuned using a population decline swarm optimization algorithm that minimize the integral of the time absolute error on the wing tip torsion angle. The performance of the closed loop system are studied carrying out numerical simulations that reproduce different flight scenarios with the presence of speed variations, disturbances, and gusts proving the effectiveness of the proposed simple adaptive flutter suppression architecture.
