Static Strain and Vibration Characteristics of a Metal Semimonocoque Helicopter Tail Cone of Moderate Size
AUTHOR | Nasa, National Aeronautics and Space Adm |
PUBLISHER | Independently Published (11/17/2018) |
PRODUCT TYPE | Paperback (Paperback) |
Description
The results are presented of an analytic and experimental research program involving a Sikorsky S-55 helicopter tail cone directed ultimately to the improved structural analysis of airframe substructures typical of moderate sized helicopters of metal semimonocoque construction. Experimental static strain and dynamic shake-testing measurements are presented. Correlation studies of each of these tests with a PC-based finite element analysis (COSMOS/M) are described. The tests included static loadings at the end of the tail cone supported in the cantilever configuration as well as vibrational shake-testing in both the cantilever and free-free configurations. Bielawa, Richard L. and Hefner, Rachel E. and Castagna, Andre Unspecified Center AIRFRAMES; HELICOPTERS; MONOCOQUE STRUCTURES; STATIC CHARACTERISTICS; STRUCTURAL ANALYSIS; STRUCTURAL VIBRATION; SUBSTRUCTURES; VIBRATION TESTS; AIRCRAFT DESIGN; COMPUTER PROGRAMS; COMPUTERIZED SIMULATION; FINITE ELEMENT METHOD; MATHEMATICAL MODELS; SIKORSKY AIRCRAFT; STRESS ANALYSIS; TAIL ASSEMBLIES...
