Expertise for All Phases of Jet Engine Testing

Whether your focus is development, production or MRO, the multi-disciplinary ASE AeroSystems engineering staff considers all facets of engine testing when meeting your facility and equipment needs — everything from airflow analysis to system integration.

This can involve leveraging our aerodynamic test laboratory to test subscale models of different test cell and nacelle equipment configurations before finalizing a design. We also frequently serve as consultants to clients looking to improve existing facility performance or expand their capabilities.

“ASE is a leading global company in engine test cell construction and always provides excellent service with high-quality results. From 2007 to 2009, China Airlines cooperated with ASE on a 120,000-pound engine test cell building project. Due to the financial crisis at the time, we were facing soaring prices in raw materials. The ASE team demonstrated their professional expertise by coordinating with each subcontractor to best meet our cost requirements. Without their dedicated performance, cohesive teamwork and enthusiasm, we wouldn't have accomplished this project successfully.”

Advanced Analytics Guide Facility Design

Under the guidance of renowned thought leader Dr. Peter Chu, the ASE Aero/Thermal/Acoustics team leverages computational fluid dynamics (CFD) modeling software and a host of proprietary analytical tools to accurately predict the aerodynamic, thermal and acoustic performance of test cells prior to facility construction.

These analytical tools and advanced CFD software offer a proven means of resolving complex test cell air-flow physics, optimizing designs for test cell renovation, reducing noise — and even increasing the engine testing capacity of existing facilities.

  • Applying equations from more than 200 performance parameters, our test cell airflow model helps determine test cell pumping efficiency, flow velocities and temperatures at various locations in the test cell flow stream.
  • Our test cell acoustic model applies dozens of characteristics determining likely noise levels at multiple locations around or adjacent to the test cell.
  • In recent test cell projects, ASE AeroSystems bar silencers have delivered superior front cell uniformity and excellent crosswind prevention compared to conventional splitter baffles. Twenty-one MRO and OEM test cells to date have been built or upgraded with ASE bar silencers to date, yielding consistently high levels of aerodynamic and acoustic performance.
