Research of several key technologies of business component in IMS-DATE

Aerodynamic design of aero turbine engine is a complex process that requires diverse engineering disciplines to execute independent of each other in sequence, usually iteratively and interactively. It involves various scientific computing packages to provide a fast, accurate, and reliable approach to model engineering problems. The calculations of aerodynamics, thermodynamics and structure are repeated continuously by many kinds of engineering computation software. The characteristics require a modular design mode. Business component is introduced in integrated management system for aerodynamic design of aero turbine engine (IMS-DATE) to deal with those difficulties, which is defined as a combinational management module that comprises design object´s attributes and corresponding processing logic, which can implement universal management of design resources and design data. Concepts of business component applied are defined, including its structure compositions and framework design. And several key technologies in implementation are illustrated, namely, hierarchical software registry, software encapsulation and parameter parsing.
