Sažetak
Most research of aviation cockpit noise focuses on engine-powered aircraft with various types of propulsion - piston, turboprop, turbojet and turbofan. This paper deals with a sailplane (glider) aircraft that, after being launched by towing aircraft, continues an autonomous, non- powered soaring flight. The interior noise is from that point predominantly generated aerodynamically by wind slipstream during progressive flight. Its level and spectrum at different speeds and wing control surface configurations, i.e. various phases of actual flight: towing take-off, assisted and thermal climb, cruise, descent and landing, were recorded in a typical sailplane aircraft and the results are presented and analyzed. Acoustical characterization of sailplane cockpit in static, onground condition, identified by MLS and TSP methods is given along with the flight safety-related speech quality metrics derived from the data assessed and compared with the results from previous research on a small engine-powered aircraft.
