Mechatronic Systems

♦ FACILITIES: infrastructure, designing tools, processing equipments

♦ TEST BENCHES FOR MECHATRONIC APPLICATIONS

1. WING FLIGHT CONTROLS TEST STAND

It is developed mainly by INCAS Mechatronics Unit, in a common location used by two Laboratories: Mechatronic System Laboratory and Mechano-Hydro-Pneumatic Laboratory.

The stand is conceived, among others, as a starting point of a wing load control ground demonstrator. The following flight controls of a specimen of naturally cantilevered wing are operated as a mechatronic system from a control room:

♥ aileron and flight spoilers

♥ speed brakes for flight ground aerodynamic braking

♥ high-lift devices:

♦ leading edge devices (slates)

♦ trailing-edge flaps

2. SMART STRUCTURES STAND

♦ active vibration control

of flexible structures

♦ structures health

monitoring (SHM)

♦ structures morphing

Smart structures have the ability to respond adaptively in a pre-designed useful and efficient manner to changes in environmental conditions, including any changes in its own condition

(V. K. Wadhawan)

Active techniques enhance dynamic behavior of the wing, without redesign and adding mass; nowadays, these are used both for flutter suppression and structural load alleviation

(I. Ursu)

Many aerospace and civil infrastructure systems are at or beyond their design life; however, it is envisioned

that they will remain in service for an extended period. SHM is one of the enabling technologies that will make this possible

(V. Giurgiutiu)

Morphing wing means that a hinged aileron and/or flap will be replaced by a structure that can transform its surface area and camber without opening gaps in and between itself and the main wing, or leading to sudden changes in cross-section which could result in significant aerodynamic losses, excessive noise and vibration in the airframe (The Aeronautical Journal, 2008)
