Rolls-Royce has achieved a significant milestone in the Adaptive Versatile Engine Technology (ADVENT) research programme into next-generation US military aerospace platforms, with the successful completion of the Preliminary Design Review (PDR).
The ADVENT technology demonstrator programme, being carried out by the Rolls-Royce North America Technologies Inc. (LibertyWorks™) unit, is funded by the US Air Force Research Laboratory (AFRL).
It focuses on variable cycle engine features to achieve a propulsion system with high-thrust capabilities for take-off and manoeuvring that, in addition, optimises fuel efficiency for long range and loiter operations.
Phil Burkholder, Chief Operating Officer, LibertyWorks, added: “In addition to the successful PDR, we are also progressing the ADVENT programme by beginning component rig testing of an adaptive fan system at our Indianapolis facilities.
“Both the PDR and the rig testing are examples of how LibertyWorks is meeting the requirements of its customer, working towards the shared vision of creating an ADVENT family of next generation engines that deliver the range and persistence required for 21st century aircraft.”
In August 2007, Rolls-Royce was awarded a $296 million contract by the AFRL for work to develop ADVENT technologies that focus on an adaptive engine architecture to provide a 25 per cent improvement in average fuel consumption and reduced temperature cooling air for thermal management. Rolls-Royce involvement in the programme includes cost-sharing with the AFRL and underscores the company’s commitment to investing in technologies, capabilities and infrastructure that will lead to continuous improvement in the environmental performance of aero engines.
