STATIC AND DYNAMIC ANALYSIS OF BLACK HAWK UH- 60 ROTOR BLADE USING COMPOSITE MATERIALS

Abstract

The Sikorsky UH-60 Black Hawk is a four-bladed, twin-engine, medium-lift utility helicopter manufactured by Sikorsky Aircraft. Sikorsky submitted the S-70 design for the United States Army's Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the YUH-60A and selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol YUH-61.  In this thesis, the BLACK HAWK UH- 60 ROTOR BLADE modeling in CREO parametric software and analysed for its strength using Finite Element analysis software ANSYS  Structural, analysis will be done in ANSYS on the different materials (s2 glass, Kevlar ) win turbine blade material steel replace with s2 glass at different speeds and different geometries.
