Change Project Summary
CHANGE (Combined morphing assessment software using flight envelope data and mission based morphing prototype wing development) is a Collaborative Project financed under the Transport (including Aeronautics) theme of the Cooperation Programme of the 7th Framework Programme of the European Comission.
The CHANGE project (Contract Number 314139) started on the 1st of August 2012, and will have an expected duration of 3 years.
A total of 9 partners participate in this project based in 4 different European Member States and 1 European Associate Member State.
Morphing in aircrafts has been studied and used throughout recent time in order to increase their flight envelope. This characteristic is of the upmost importance in order to offer a greater efficiency, versatility and performance during the assigned mission. Moreover an aircraft with the capability to adapt itself to each given situation is prone to achieve positive results to a range of different missions instead of requiring a specific aircraft to conduct one specific mission.
The main objective of this project is to study and develop a novel morphing system which integrates up to four different morphing mechanisms into in a single wing and to demonstrate this new ability in flight. This system would take advantage of all the performance improvements achieved by adopting its wing shape according to the mission requirements of each flight phase. Therefore, this project envisions to mitigate the required energy (and thus fuel consumption) to maintain the aircraft’s flight and to perform the necessary flight maneuvers by offering the capacity to mold the exterior of the aircraft in order to enhance the necessary aspect of flight so as to lessen the required energy, such as lift over drag ratio, efficiency in aerodynamic control, lower stall velocity or to change to a better planform to perform a required maneuver. In order to prepare the basis for an eventual cognitive morphing on-board controller which ability is focused in the autonomous control of all morphing system of the wing, it is necessary to develop a software that is capable of rendering the most efficient morphed wing based on the information of the current phase. This software would therefore, be able to conduct an assessment of the introduced flight conditions of the wing and display the accordant morphed wing (using a database with all current morphing systems) capable to fly with the highest performance.
