Abstract
The extreme structural damage/malfunction scenarios such as partial loss of wing or vertical fin, jamming, or partial loss of control surface(s) are not catered in flight control laws of conventional FBW aircraft. Hence, such scenarios are never flight-tested because of the dangers involved. This paper brings out the challenges and lessons learnt during the assessment of Handling Qualities (HQ) evaluation while developing Intelligent Reconfigurable Control laws (RICL) to exercise control of a fighter aircraft model with a certain set of impairment/partial damage using a desktop-based simulator. Reconfigurable flight Control laws were developed to recover a conventional Fly By Wire(FBW) aircraft under loss of wing or vertical tail scenarios and the same was evaluated for different flight phases such as Air combat, Cruise, etc. to obtain Cooper-Harper Ratings from three experimental test pilots using real-time simulation test setup. Based on the Flying Qualities (FQ) and HQ flight test evaluations restricted flight envelopes and appropriate recovery techniques were arrived at for such scenarios that can be used for documentation in flight manuals and training of Air Crew in case they face such situations. This paper tends to give a brief overview of fault detection and control reconfiguration methods based on intelligent control techniques and their FQ/HQ evaluation.
