National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

AD905910

Publication Date	1972
Personal Author	Dominick, F. L.; Bender, G. L.; McClellan, R. D.; Hall, G. C.; Stringer, P. G.
Page Count	346
Abstract	The Army Preliminary Evaluation I and a portion of the Reserach and Development Acceptance Test I were conducted periodically on the AH-56A Cheyenne compound helicopter. Primary test objectives were to gather stability and control data to provide an early assessment of the AH-56A, to assist in determining flight envelopes for future Army tests, and to examine previously identified problem areas. The capability of the pusher propeller to provide rapid deceleration and to control airspeed independently of dive angle is an excellent feature. Five deficiencies and 54 shortcomings were identified. Correction of the deficiencies should be a prerequisite for an airworthiness release for operational Army aviators, and correction of the shortcomings is desirable. Further testing of the AH-56A is recommended.
