Aircraft Design and Testing of FLEXOP Unmanned Flying Demonstrator to Test Load Alleviation and Flutter Suppression of High Aspect Ratio Flexible Wings

Ground Testing of the FLEXOP Demonstrator Aircraft

“…Having established the theoretical methods for wing shape and load calculation and validated their applicability using simulation data by Roessler et al, 1 ground testing data was collected for the calibration and validation of the methods with experimental FBG data, prior to flight testing.…”

“…Both, passive load alleviation as well as active flutter control are to be demonstrated and assessed in flight using an unmanned aerial vehicle(UAV). 1 Various aspects of the project leading up to the testing of the aircraft have already been presented. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] In order to conduct the flight tests in a safe and efficient manner a number of ground tests were performed.…”

H∞ Control Design for Active Flutter Suppression of Flexible-Wing Unmanned Aerial Vehicle Demonstrator

“…Its aim is to develop multidisciplinary aircraft design capabilities by achieving a closer coupling of wing aeroelasticity and flight control systems in the design process. A flexible-wing remotely piloted demonstrator is designed in the framework of this project [15,16] and will be used to achieve flight-test validation of aeroelastically tailored design [17] and AFS [18,19]. A concept drawing of the demonstrator is presented in Fig.…”

Aircraft Aeroservoelastic Modelling of the FLEXOP Unmanned Flying Demonstrator

“…The present paper focuses on the aeroservoelastic modeling aspects within the Flexop project and has been presented together with papers on the design 10 and controller development 11 of the Flexop UAV, and along with work 12-14 on the Performance Adaptive Aeroelastic Wing (PAAW) project in a joint Flexop-PAAW session.…”
