Performance Characterization of Air Breathing Engine

You may download a PDF copy of this article from here.

Our customer in the Republic of Korea is engaged with conceptual design and development of supersonic air breathing engine. The engine is based on mixed-compression air intake, subsonic combustor, fuel injection system and a nozzle. A mathematical model was desired to be developed for estimating and understanding its working over its flight envelope. The development of such multi-component mathematical model required a multi-disciplinary group with deep expertise in development of numerical simulation tools.

Zeus Numerix selected the most appropriate techniques for component wise simulation and then integrated them all into a common framework for system level performance prediction. It included 3-D CFD simulations for air intake, 1-D detailed chemical kinetics of JP-10 for subsonic combustor and empirical modules for fuel injection and nozzle functioning. A novel system level dynamics framework to integrate the component modules was designed and implemented.

Customer was provided with a well documented integrated framework, its validation studies and analysis report. The framework was further used by the customer to devise control strategies for this engine. Through this engagement with Zeus Numerix, customer overcame the critical constraint on availability of R&D resources with expertise in development and usage of numerical methods.
