An Integrated Time-Domain Aeroelasticity Model for the Prediction of Fan Forced Response due to Inlet Distortion
(The American Society of Mechanical Engineers (ASME), 2002)The forced response of a low aspect-ratio transonic fan due to different inlet distortions was predicted using an integrated time-domain aeroelasticity model. A time-accurate, nonlinear viscous, ... -
Evaluation of Acoustic Flutter Suppression for Cascade in Transonic Flow
(The American Society of Mechanical Engineers (ASME), 2002)Flutter suppression via actively excited acoustic waves is a new idea proposed recently. The high flutter frequency (typically 50–500 Hz for a fan blade) and stringent space constraint make ... -
Contact Stresses in Dovetail Attachments: Finite Element Modeling
(The American Society of Mechanical Engineers (ASME), 2002)The stress analysis of dovetail attachments presents some challenges. These challenges stem from the high stress gradients near the edges of contact and from the nonlinearities attending conforming ... -
Effect of Crystal Orientation on Fatigue Failure of Single Crystal Nickel Base Turbine Blade Superalloys
(The American Society of Mechanical Engineers (ASME), 2002)High cycle fatigue (HCF) induced failures in aircraft gas turbine and rocket engine turbopump blades is a pervasive problem. Single crystal nickel turbine blades are being utilized in rocket ... -
In-Cylinder Pressure Reconstruction Based on Instantaneous Engine Speed Signal
