The handling qualities (HQs) of helicopters have been a subject of considerable interest and concern for safety of piloted flights. “Handling qualities” represent the integrated value of helicopter stability (or instability) in flight, helicopter controllability and pilot’s ability to maneuver the helicopter. The current practice of assessing helicopter HQs still reveals significant gaps in its criteria, however.
The main objective of this project is to develop novel, multi-disciplinary performance-vibratory HQ criteria which are better capable of quantifying the effects of vibratory loads on HQs, pilot workload and the helicopter automated flight control systems. This will ensure the understanding of future extended helicopter flight envelopes, including very demanding maneuvers which impose heavy vibrations on both structure and pilot. For this project simulation models, missions and environments will be developed and assessed in a multi-disciplinary manner in the flight simulators available to the NITROS project.
The ESR will need: 1) to understand how pilot manual control performance is affected by structural loads and vibrations, and 2) to perform parallel structural load alleviation and performance enhancement through a model-based approach. Several helicopter HQs criteria given by the Aeronautical Design Standard ADS-33 will be extended to vibratory loads criteria for multidisciplinary helicopter design. This project builds on the helicopter simulation models available at TU Delft and POLIMI. It uses the SIMONA Flight Simulator (SRS) from TU Delft and other simulator facilities available to the NITROS project.
The researcher will be working with TU Delft (The Netherlands) and POLIMI (Italy) towards a dual doctorate degree. Secondments to research institutes will be performed at National Aerospace Center (NLR) in the Netherlands and at the Civil Aviation Authority (CAA) for practical implementation of extended HQs criteria into the helicopter standards.
