    Abstract
  • Feature-based aeroengine blades design is researched in concurrent engineering environment. Based on the analysis of the basic features of various aeroengine blades, parametric feature modeling technology and object-oriented method, feature architecture of aeroengine blades,and a 3D solid blade feature modeling system are developed according to STEP (AP203/AP214) on design platform LONICERA,which is an advanced integrated mechanical (CAD/CAM) design environment developed by Beijing University of Aeronautics and Astronautics. The data exchange with STEP is accomplished. A solid model is transmitted from design platform to analysis platform (MSC/ PATRAN/ NASTRAN), then strength and vibration analysis of a turbo-fan engine blade is carried out.
