Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a limited Phase D Engineering Flight Test of the YUH-1H helicopter equipped with the Lycoming T53-L-13 engine. The objectives of the test were to define the increased performance, to evaluate the engine characteristics and to investigate the flying qualities resulting from the expanded flight envelope. One hundred and fifteen data flights were conducted from December 1966 to August 1967 accounting for 98 productive flight hours. Testing was conducted in California at Edwards Air Force Base and at auxiliary test sites at Bakersfield and Bishop. Helicopter performance was quantitatively defined for hover, takeoff, climb and level flights. Engine characteristics and helicopter flying qualities were determined quantitatively at specific flight conditions and were qualitatively investigated throughout the operating flight envelope. The performance of the UH-1D was significantly improved by the installation of the higher powered T53-L-13 engine which resulted in an increased weight, temperature and altitude flight envelope. The T53-L-13 engine demonstrated good dynamic characteristics except for instability at topping power and poor static characteristics. In general, the helicopter flying qualities were acceptable in forward flight. During low-speed flight and hover, the left directional control margin was inadequate. At a forward center of gravity, the helicopter has insufficient aft longitudinal control. To safely use the increased flight envelope, the control deficiencies must be corrected.

This book was released on 1982 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Army Aviation Engineering Flight Activity conducted level flight performance tests of the UH-1H helicopter to provide data to determine the most fuel efficient operating characteristics. Hot and cold weather test sites were used to extend the advancing tip Mach number data range to supplement existing YUH-1H performance data. Based on preliminary analysis, range can be increased significantly at optimum altitude and rotor speed compared to sea level and normal rotor speed (324 RPM). Rotor compressibility effects were significant at all test conditions.

Book Synopsis Helicopter Test and Evaluation by : Alastair Cooke
Download or read book Helicopter Test and Evaluation written by Alastair Cooke and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although a number of texts on helicopter aerodynamics have been written, few have explained how the various theories concerning rotorborne flight underpin practical flight test and evaluation. This book combines theoretical information on aerodynamics, stability, control and performance with details of evaluation methodologies and practical guidance on the conduct of helicopter flight tests. For each topic the relevant theory is explained briefly and followed by details of the practical aspects of testing a conventional helicopter. These include: * safety considerations * planning the tests * the most efficient way to conduct individual flights Where possible typical test results are presented and discussed. The book draws on the authors' extensive experience in flight test and flight test training and will appeal not only to professionals working in the area of rotorcraft test and evaluation, but also to helicopter pilots, rotorcraft designers and manufacturers and final year undergraduates of aeronautical engineering
