This lecture provides a systematic review of flight test techniques and test data interpretation methods for helicopter performance and flying qualities. The distinction is drawn between quasi-steady and dynamic testing and within these categories both clinical and role-related techniques are discussed. Performance topics covered include steady state performance in hover and forward flight, flight envelope boundaries, take-off and landing performance, and helicopter agility. Flying qualties topics begin with a treatment of static stability tests and progress to dynamic stability, control response, system identification and role-related evaluation techniques. Testing appropriate to certification and development phases and research activities are addressed. The exploratory nature of flight testing is evident throughout this work and safety aspects are emphasised when required. Results from recent and past test programmes are used to illustrate the forms in which flight data can be presented, and data reduction and analysis methods established and under development are reviewed.
