- Abstract
Airbreathing hypersonic vehicle is a highly integrated engine and airframe vehicle, which design process is different with other traditional vehicle, propulsion system has very close relationship with performance of vehicle. In our early research work (IAC-04-S.5.11), scramjet was designed and optimized alone, but such design result could not satisfy requirements of vehicle integrated performance. Thus, in our following research work (IAC-05-C4.5.07), effects of lift and moment of scramjet produced from difference flowpath design on trim performance of vehicle were emphatically analyzed. Through these works, it is a definite conclusion that hypersonic vehicle must be designed by propulsion system with vehicle airframe together and must consider multidisciplinary performance requirements. For design and analysis of airbreathing hypersonic vehicle conveniently, it is needed to build an integrated design environment, according to its design process. Such design environment should can generate a series of design scheme, and evaluate integrated performance of hypersonic vehicle. The Software tool we developed is not an all-in-one design and analysis software, however, it is a core of design framework, and it give a series of convention of data exchange and transfer, and a system of data manage. Open interface for data make this software tool can connect with some commercial software and in-house programs. In this software tool, through interactive design, baseline design scheme is generated, and the strategy of evaluating performance is specified, consequently other software or programs begin to analyze or detail design in parts. Final design result will be collected to this software tool and are displayed. The software tool also can be connected with optimization software or code, to conduct multidisciplinary design optimization for integrated performances. Preliminary version of this software tool had been used in research work presented in paper IAC-05-C4.5.07 to investigate effects of scramjet flowpath design on vehicle trim performance. Recently, this software tool has been further developed and used in the design of hypersonic vehicle to get the thrust/drag balance and the lift/weight balance. All these design results show the feasibility of this software tool. This software tool can satisfy the design requirements of airbreathing hypersonic vehicle, and integrated design framework and environment be built around it will have engineering meaning for future hypersonic vehicle development.
