Project 10: CH-53 Aeroelastic Simulation Model

Summary of Services Performed: Develop RCAS model of CH-53 for aeroelastic analysis ART is supporting Sikorsky Aircraft in modeling the CH-53 helicopter in the RCAS. The focus of this effort is on detailed aeroelastic modeling and running tests under high load factors. ART provided number of reports analyzing the results of RCAS in comparison with flight tests. Among them the identification of Floquet Transition Matrix roots and the effects of elastic swashplate on the aeroelastic stability of the rotor can be named.

ART is also supporting an aircraft manufacturer in modeling new coaxial rotor helicopter UAV in RCAS. This manufacturer is using RCAS to analyze the mutual interference of the two rotors.
