摘要
Abstract
A multidisciplinary analysis toolchain specifically for rotorcraft has been developed at JAXA.HeliDesign provides the sizing of a conventional or a compound helicopter to meet the specified mission requirement based on preliminary semi-empirical relations.rFlight delivers the trim analysis and performance of a rotorcraft together with the linearized flight dynamics models based on analytical formulations of the rotor aerodynamics from blade-element theory.rBET/RMT is a low fidelity tool based on blade-element theory.For high-fidelity aeroelastic analysis of a rotating blade,rFlow3D is constructed based on high-resolution CFD and loosely coupled with computational structural dynamics(CSD)to obtain the elastic deformations of a rotor blade,while the natural frequencies and modes are obtained using rMode.rGrid tools support the automatic grid generations around a rotor blade to be computed in rFlow3D.Acoustic signature from a rotorcraft can be predicted using rNoise based on the FW-H equations using the output from rFlow3D.These tools have been applied for new rotorcraft developments and the high-fidelity toolchain has been validated with reliable test data with satisfactory accuracy.关键词
