Efficient Prediction of Aerodynamic Control Surface Responses Using the Linear Frequency Domain

What is it about?

The application of load alleviation capabilites on aircrafts, for example by the right usage of control surfaces, has a great potential for enabling weight savings (and thereby reduced fuel consumption) and increasing passenger comfort. However, the computational prediction of the aerodynamic responses for the control surfaces are very time-consuming using the conventional time-marching methods. We developed a new method, which is able to achieve the same prediciton accuracy within a mere fraction of the time using the advantages of the linear-frequency-domain.
