Rolls-Royce has completed testing on a new, advanced technology compressor focusing on reduced fuel consumption.
The Rolls-Royce Highly Energy Efficient Turbine Engine (HEETE) compressor successfully demonstrated its ultra-high pressure ratio performance goal and an ability to manage component temperatures at ultra-high ratio design conditions through advanced thermal management. During testing at the US Air Force Research Laboratory (AFRL), the HEETE compressor achieved the highest pressure ratio ever demonstrated at AFRL's Compressor Research Facility.
Mark Wilson, Chief Operating Officer - LibertyWorks, said, “This successful ultra-high pressure ratio testing validates the Rolls-Royce compressor design. The advanced compressor technology can be applied to future transport, patrol and ISR applications, ranging from our successful AE family to larger engine applications. The advanced technology will help meet the future needs of the US military by increasing range and persistence, while reducing fuel consumption.”
“The Rolls-Royce HEETE program is one of several advanced technology programs under way at our LibertyWorks unit. LibertyWorks has successfully completed designs for all major US airframe companies, as well as NASA, and has demonstrated success through ADVENT and other advanced technology programs.”
Rolls-Royce is one of two companies selected for the HEETE advanced compressor technology program to design next-generation propulsion systems for the US Air Force. The development work is being carried out by the company's LibertyWorks research unit in Indianapolis, Indiana, US. In 2007, the US Air Force Research Laboratory (AFRL) awarded the program to Rolls-Royce in a contract that is valued at $25.3 million.
HEETE is a technology development program that pursues high temperature, high pressure ratio compressor technologies and their related thermal management features. While this initial HEETE testing was focused on an advanced compressor demonstration, the goal is to define the next generation engine architecture for subsonic missions, such as Transports, Tankers, ISR (Intelligence, Surveillance, and Reconnaissance) and Subsonic Strike Vehicles.
