The Aerospace Propulsion Division (AFRL/PRA) of the Propulsion Directorate (AFRL/PR) is paving the way for the next generation of high speed air-breathing vehicles and combined cycle - access to space vehicles. To achieve this end, we are looking for industry partner(s) to research, develop and test innovative design(s) for scramjet inlet, isolators, combustor, fuel injectors, and nozzle, i.e., engine flowpath. The overall arching Robust Scramjet program will develop, integrate and demonstrate various technologies necessary to establish the technology base for second generation liquid hydrocarbon and H2 fueled scramjet propulsion system concepts suitable for a potential follow-on flight-weight engine demonstration program. The Statement of Objectives for this contract is divided into three distinct areas .The first area requires industrial partners to address the fundamental issues associated with scramjet engine operability and expanding the Mach number capability to Mach 3-8+ for hydrocarbon fuel. Offerors are encouraged to use their expertise to increase the understanding in this area and to develop methods and schemes (computational and experimental) that would give as wide an operability range as possible and still meet the goals and objectives set by AFRL engineers and scientists. The contractor shall define the tasks and propose the approach to completing them. The contractor shall address how his approach fits in the overall picture and how it can be modified with minimum changes to adapt to the inlet, isolator, combustor, and nozzle. These components could have various geometries to include, square-rectangular and round-elliptical cross-sections. Scaling capability is an essential element of the modeling approach. The work should focus on designs for expendable missile applications. However, it is expected that the contractor offers and demonstrates the methodology capable of carrying the design to HC and finally H2 (or other fuel) reusable vehicle applications. The modeling/design effort should consider variable geometry inlets, which may be required to increase performance, improve operability and provide the capability to lower the Mach number for scramjet take-over to 3.0-. The long-term objectives being 1) improved performance and operability of hydrocarbon and H2-fueled scramjets 2) the ability to repeatedly cold start a scramjet engine in flight. The second area requires industrial partners to address the fundamental issues associated with enhancing engine durability for the HC expendable hypersonic cruise missile application and reusable engine structures for the affordable on-demand space access and long range intel/strike/recce aerospace vehicle. Offerors are encouraged to consider the use of existing flight-weight structures and materials for required performance and operability. New materials are to be developed and fabrication methods are to be identified where and when necessary. When feasible, subscale hardware are to be designed and fabricated to assess component operability and durability to reduce program risks. Structural durability will be increased from minutes, for single use applications, to hours for reusable systems. This technology is to be demonstrated in future tests of subscale inlet/isolators, sub- or full-scale direct connect isolator/combustors, and in semi-free or free-jet facilities. Post test analysis will be conducted to verify and validate design methodologies and design improvements and lessons learned will be incorporated. High-fidelity analytical tools will be employed to leverage experimental efforts and provide guidance for defining requirements for subsequent flight testing. The third area requires industrial partners to address the fundamental issues associated with scalability issues for the three classes of proposed vehicles such as the HC expendable hypersonic cruise missile, the space access, and the long range intel/strike/recce aerospace vehicles. Offerors are encouraged to use their innovative ideas and expertise to increase the understanding in this area. In order to develop scramjet scaling tools and methodologies, one will need to investigate and evaluate all aspects of scramjet flowpath, including novel injection schemes for enhanced mixing and high combustion efficiencies. Alternative engine cross sections are to be addressed to improve engine scaling while maintaining a wide range of operability, high performance, and structural integrity. High-fidelity analytical tools will be employed to leverage experimental efforts and provide guidance for defining requirements for subsequent flight testing. System and vehicle design studies performed by AFRL/PRA shall be used to guide the propulsion system design and engine/airframe integration wherever applicable.Proposal shall contain a description of the overall program as envisioned by the bidders and detailed information on one or more of the following three Delivery Orders: (1) Scramjet Flowpath Integration, (2) Component Technology Development, and(3) Advanced Concepts. It is anticipated that the results of this effort directly feed to future technology programs such as Combined Cycle Engines.
