Abstract

Morphing wing devices can improve the aircraft performances thanks to the possibility to change the wing shape throughout the mission. Dedicated design procedures, based on optimization techniques, have been applied in several research projects to realize leading and trailing-edge devices able to enhance the high lift performances during take-off and landing phases. In the framework of Clean Sky 2 REG-IADP AIRGREEN 2 (AG2) project, the morphing Droop Nose has been one of the devices conceived for application on a regional transport aircraft. The numerical design has proven to be very promising, but the expected performances must be confirmed by a real demonstrator. This paper describe the design, manufacturing and testing of a full-scale prototype of the droop nose. The purpose of the activity is to demonstrate the benefits of morphing, experimentally validating the numerical results. The main concern of the work has been the achievement of a feasible solution based on the use of conventional aeronautical materials. The experimental tests have assessed the device functionality, demonstrated the structural feasibility and validated the achieved morphing shape. Moreover, the experimental activity has been fundamental to highlight critical aspects and to solve the issues related to the proposed technology, with particular attention to the manufacturing phase.
