A Review of Recent Aeroelastic Analysis Methods for Propulsion at NASA Lewis Research Center

摘要: This report reviews aeroelastic analyses for propulsion components (propfans, compressors and turbines) being developed used at NASA LeRC. These include both structural aerodynamic models. The models a typical section, beam (with without disk flexibility), finite-element blade model plate bending elements). are based on the solution of equations ranging from two-dimensional linear potential equation to three-dimensional Euler multibladed configurations. Typical calculated results presented each model. Suggestions further research made. Many currently available analysis methods incorporated in unified computer program, APPLE (Aeroelasticity Program Propulsion LEwis).
