Abstract:
In this work interval analysis is applied to find the trimpoints of the Innovative Control Effectors aircraft model. At low speed the method is capable of finding interval enclosures of single trim points with a high accuracy. At higher speeds the found accelerations are larger. When looking for a full trim set the method finds continuous bounds on the control effectors for the entire input range in one run. This is a good demonstration of the advantages that interval analysis has over conventional methods that generally can only find one trim point at a time. However, remaining accelerations can be too large to be acceptable as trim conditions. On the other hand the potential that interval analysis has as a trimming method is demonstrated, since continuous bounds on trim sets have been found in a single run.
