Avetec is developing the virtual engine test cell so that complex engineering systems, like aircraft engines, can be computationally simulated at a high level of detail early in the design process to reduce the time and cost of developing these systems. Technologies that will be developed for the virtual engine test cell can be applied to the simulation of a wide variety of other complex systems such as ground-based power systems, rocket engines, automobiles, aircraft, and the human anatomy.
Much of the research in full engine simulation to date has focused on the GE90, the largest thrust engine in the world. This effort began in 1985 by analyzing a single blade row passage and building up to components such as the compressor, combustor, and turbine. The core was completed in 2001, and the entire engine was simulated at a takeoff condition based entirely on steady-state numerical simulation in 2004. In 2006, Avetec and NASA Glenn unveiled the first full system, full annulus, three-dimensional Computational Fluid Dynamics (CFD) simulation of the GE90 at a single operating point. Research continues to develop an adequate simulation of the unsteady flow phenomena in the components and the engine as they affect the operational aspects of the propulsion system.
