Rolls-Royce North American Technologies, Inc. has achieved a major milestone in the Adaptive Versatile Engine Technology (ADVENT) demonstrator program, and was selected by the U.S. Air Force to proceed with Phase II development. Next steps for this key USAF technology program will include the integration of a variety of advanced technologies, component testing and development of a technology demonstrator core and engine.

This authorization to proceed follows successful completion earlier this year of a series of tests and analysis on a technology demonstrator core and adaptive engine. Designed to provide significant improvement in average fuel consumption, this core and engine will be available for future U.S. military aerospace platforms, including medium or large unmanned air systems.

Phil Burkholder, Chief Operating Officer, Rolls-Royce North American Technologies, Inc., added: "We are delighted to continue to support the shared vision of creating an ADVENT family of next generation engines that deliver the range and persistence required for 21st century aircraft, including unmanned air systems. The relationship with the AFRL is one of our most long standing, and we look forward to continuing our partnership on the ADVENT program that will deliver a step-change in aerospace propulsion technology."

The ADVENT technology demonstrator program, undertaken by Rolls-Royce North American Technologies, Inc. (LibertyWorks), is funded by the U.S. Air Force Research Laboratory (AFRL). ADVENT is part of the Versatile Affordable Advanced Turbine Engines (VAATE) Program, an initiative sponsored by industry and Government partners to advance state of the art turbine engine technology for military and commercial aviation.
