Rolls Royce Developing Fuel Efficient Jet Engine

Rolls-Royce, has initiated testing on a new, advanced technology engine compressor focusing on reducing fuel consumption.

Rolls-Royce was selected for the HEETE (Highly Energy Efficient Turbine Engine) advanced 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 $24.3 million.

HEETE is a technology development program that pursues high temperature, high pressure ratio compressor technologies and their related thermal management features. While HEETE is currently 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.
LibertyWorks has successfully designed and tested propulsion technology through the ADVENT program, as well as research conducted for NASA and the major US airframe companies.
