Hover performance calculations are performed for a 9.34 ft, four-blade, Mach-scaled, S-76 rotor with an anhedral tip using different computational-fluid-dynamics approaches to assess the variability in predictions. Time-accurate Navier–Stokes calculations are performed using the High Performance Computing Modernization Program Computational Research and Engineering Acquisition Tools and Environments Air Vehicles Helios software suite with OVERFLOW and FUN3D as near-body solvers, and the standalone ...

Progress on two programs to evaluate composite structural components in flight service on commercial helicopters is described. Thirty-six ship sets of composite components that include the litter door, baggage door, forward fairing, and vertical fin were installed on Bell Model 206L helicopters that are operating in widely different climatic areas. Four horizontal stabilizers and ten tail rotor spars that are production components on the S-76 helicopter were tested after prescribed periods of service ...

Sikorsky Aircraft undertook in 1977 a program which was aimed at setting the stage for future reductions in the amount of flight testing required for helicopter certification. This program was initiated by exposing FAA personnel to the makeup of the analytic program and the correlation obtained with flight test data using this program. Subsequently, the analytic model, was used to predict S-76 flight characteristics so as to provide a priori data for correlation with the flight data generated during certification testing. The analytic flight dynamic model, Gen Hel, has been used extensively at Sikorsky for stability and control evaluations and in conjunction ...
