Pratt & Whitney Rocketdyne awarded propulsion system development contract

  • 30-Sep-2009 02:03 EDT

Lockheed Martin awarded Pratt & Whitney Rocketdyne a 10-month contract for preliminary design of the high-speed accelerator for a turbine-based combined-cycle (TBCC) propulsion system, which could support flight up to Mach 6. In Phase I of the TBCC Mode Transition Demonstrator Program, Pratt & Whitney Rocketdyne will develop preliminary designs for a dual-mode ramjet combustor with related control and fuel system components. Pratt & Whitney Rocketdyne will also define requirements for a test facility to perform TBCC propulsion system mode transition tests. The TBCC propulsion system consists of a turbojet engine, which can operate from takeoff to Mach 3, and a ramjet engine, which can operate from Mach 2.5 to Mach 6. Applications for the TBCC propulsion system could include reusable hypersonic cruise vehicles for strike and reconnaissance missions.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
