Book excerpt: The Phase D, Part 3 Airworthiness and Qualification Aircraft Vibration Tests of the AH-1G Helicopter were conducted. Six vibration parameters were evaluated to determine model specification compliance and mission suitability information for inclusion in technical manuals and other publications. The vibration levels of the AH-1G met all requirements of the detail model specification; however, a reduction in the vibration levels at airspeeds from maximum level-flight airspeed (VH) to limit airspeed (VL) is desirable for improved mission suitability. The detail model specification did not require any specific vibration levels at airspeeds other than VH. Future detail model specifications should contain vibration limits for all flight conditions and aircraft configurations.

This book was released on 2018-07-23 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA-Langley is sponsoring a rotorcraft structural dynamics program with the objective to establish in the U.S. a superior capability to utilize finite element analysis models for calculations to support industrial design of helicopter airframe structures. In the initial phase of the program, teams from the major U.S. manufacturers of helicopter airframes will apply extant finite element analysis methods to calculate loads and vibrations of helicopter airframes, and perform correlations between analysis and measurements. The aforementioned rotorcraft structural dynamics program was given the acronym DAMVIBS (Design Analysis Method for Vibrations). Sikorsky's RDYNE Rotorcraft Dynamics Analysis used for the correlation study, the specifics of the application of RDYNE to the AH-1G, and comparisons of the predictions of the method with flight data for loads and vibrations on the AH-1G are described. RDYNE was able to predict trends of variations of loads and vibrations with airspeed, but in some instances magnitudes differed from measured results by factors of two or three to one. Sensitivities were studied of predictions to rotor inflow modeling, effects of torsional modes, number of blade bending modes, fuselage structural damping, and hub modal content.
