Morphing Value Assessment on Overall Aircraft Level

In order to assess the benefit of the morphing devices developed in the framework of SARISTU, integration in an overall aircraft model is required. For this purpose, the relevant input data regarding the adaptive leading-edge, trailing-edge and winglet devices are gathered with specific focus on weight and aerodynamic performance. Different levels of detail are applied. For weight and actuation power, the methods range from geometry (e.g. span and chord)-dependent methods to absolute delta values which are for instance subtracted from components weights as wing structure weight. Methods for aerodynamic data reach from subtractions of absolute values from the lift to drag ratio, constant for the flight phases (i.e. climb, cruise, decent), towards changes to the induced drag polars specific for each mission increment and dependent on the explicit lift coefficient. For an objective assessment, several aircraft models are compared. The assessment and comparison of these aircraft AC models take place on standard overall aircraft-level parameters as block fuel or maximum take-off weight.
