Research and technologies for aerospace propulsion systems (rtaps) statement of work 1.0 objective the objective of this proposed task order contract is to develop, demonstrate, and verify advanced propulsion system technologies as part of NASA s ongoing, long-term aerospace research programs, addressing a wide variety of propulsion issues. Applications include subsonic, supersonic, hypersonic, and rotorcraft transportation vehicles, as well as aviation safety and space exploration applications. 2.0 scope the contractor shall furnish all personnel, facilities, equipment, material, supplies, and services, except as may be expressly set forth in the contract agreement as government furnished property, and otherwise do all things necessary to, or incident to, performing and providing the work efforts set forth in the following areas. Contract scope includes analytical and experimental investigations covering a wide variety of propulsion components and sub-components having either government, commercial, or military application. . This contract may be used to support all NASA centers that require work within the scope of this statement of work. The contractor shall perform task orders in the following technology areas: 2.1 reserved 2.2 reserved 2.3 technology area 3: integrated rotorcraft propulsion airframe systems technology the contractor shall investigate and develop advanced integrated propulsion-airframe technologies to enable future rotorcraft to obtain high cruise speed, large payload and long range capability, and ultra-safe and low noise operations that will be required of next generation vertical lift civil transport systems. The contractor shall develop integrated propulsion system technologies for a variable speed rotor, with the goal of maximizing variation of rotor rotational speed (up to 50 percent) with no impact on flight handling quality and minimum impact to propulsion system weight. A variable speed rotor will reduce the cabin and community noise while increasing rotorcraft vehicle performance. The contractor shall perform research and development in this technology area with particular focus on advanced transmission technologies, integrated propulsion system technologies, and airframe icing and propulsion health management technologies. The technical elements included in technology area 3 are as follows:: 2.3.1 concept development and systems studies the contractor shall perform concept development and system studies of nontraditional propulsion and/or vehicle arrangements and advanced aerospace systems configurations to meet NASA program goals. These concepts include unconventional airframes and engines, advanced gearboxes, electric motors, alternative fuels, heat transfer devices, propulsion integration and advanced aerospace systems. System studies include performing system analyses and designs of aerospace vehicles with emphasis on propulsion systems installations to evaluate advanced technologies and aerospace system concepts that have the potential for improving system performance, weight, emissions, fuel burn, noise and costs. The scope of work under this element includes the following: (1) the contractor shall develop and validate empirical, statistical, and physics-based analytical models which are robust enough to handle non-conventional configurations. These models may be used for understanding the basic underlying physical phenomenon of the system or subsystem as well as for predicting aerospace systems and/or component performance, weight, emissions, reliability, life and cost. (2) the contractor shall define goals and figures of merit for overall systems as well as for individual technologies within the context of overall program/project goals and objectives. (3) the contractor shall conduct technology trade studies, mission analyses and market/cost scenario studies to identify and evaluate aerospace systems and assess their contributions towards
