Tests were conducted to simultaneously measure exterior fuselage noise, structural vibration, and interior noise of a YC-15 Advanced Medium-Range Short-Takeoff and Landing Transport airplane that employs an under-the-wing, externally-blown-flap powered lift system. The data obtained are of high quality and constitute a comprehensive data base of static ground tests at various flap and engine settings and flight tests at typical STOL takeoff, taxi, cruise, and landing.
