摘要

In an effort to assess the suitability of the HPCMP CREATE-AV Helios computational tool for calculating tiltrotor aeromechanics characteristics, comparisons of rotor performance, blade pitch, and blade loads between calculations and test data are presented for the Tilt Rotor Aeroacoustic Model (TRAM) rotor in helicopter mode at an advance ratio of 0.15. The Helios calculations are performed by coupling the computational fluid dynamics solver FUN3D with the comprehensive analysis tool RCAS along with modeling the gimbal motion of the rotor. For rotor performance and blade pitch, the comparisons are with test points that form shaft angle sweeps for two different thrust levels. For blade loads, the comparisons are analyzed in detail for two test points with 3° forward shaft tilt and different thrust levels. The level of agreement between calculations and test data is very good for rotor performance, blade pitch, and blade airloads. The level of agreement is mixed for blade structural loads and the issues are discussed.
