- Description
- The Aerospace Propulsion office of the Propulsion Directorate is paving the way for the next generation of high speed air breathing vehicles and combined cycle access to space vehicles. To accomplish this task we are looking for industry partner(s) to research, develop and test innovative design(s) for scramjet inlets, isolators, combustors and fuel injectors i.e., engine flow path. The work is to be performed primarily on-site at Wright-Patterson Air Force Base. The contractors are expected to work closely and interactively with government scientists and engineers and with other Propulsion Directorate contractors in executing this research and development effort. Award winners are expected to test their ideas or hardware in the three high speed propulsion experimental facilities within the directorate. They will be allowed to modify facility software and hardware, if necessary and upon approval of AF program manager, in order to accomplish their SOW(s). Contractors are expected to operate and maintain these facilities as necessary in order to conduct their research and development tasks. This includes complying with all applicable safety, environmental and hazardous material handling regulations. The Statement of Objectives for this contract is divided into two distinct areas. The first area requires an industry partner to address the fundamental issues associated with high-speed compressible flow phenomenon and flame holding in a scramjet. Offerors are encouraged to use their innovative experimentation and diagnostics expertise to increase the understanding in this area. As part of this area one will need to investigate and evaluate injection and mixing phenomenon associated with hydrocarbon fueled scramjet combustors, including novel injection schemes and novel fuel candidates. To ensure continuous combustion, irrespective of flight conditions, active control loop sensing and actuating systems will need to be developed. These closed loop systems should compensate for inlet start transients as well as changes in the thermal throat conditions, which can destabilize extinguish the combustion process. The second area will require an industry partner to use state of the art experimental tools to design, develop and test fixed and/or variable inlet geometry hydrocarbon-fueled scramjet inlets, isolators and combustors over flight Mach number range from 3.5 to 8. The long-term objectives being 1) improved performance and operability of hydrocarbon-fueled scramjets (alone and as part of a combined cycle engine) 2) the ability to repeatedly cold start a scramjet engine in flight. We anticipate this effort to be an IDIQ (Indefinite Delivery Indefinite Quantity) Type Contract. Over the next five-year period, PRA proposes to investigate several areas of interest, and bidders should consider these topics as they propose to the basic technical effort. Delivery Orders may be placed in the future for the following areas: Area 1: Exploration of shock / boundary-layer interactions, of particular interest will be the influence of various duct geometries on the shock/boundary-layer interactions will be investigated. Of particular interest is the influence of various duct geometries on the shock/boundary-layer interactions and methods for controlling the interaction such as mass injection, boundary-layer energization, etc.). Fuel injection, fuel-air mixing, and flame stabilization are areas to be studied. Physical dimensions of scramjet engine flow-paths vary substantially for different applications. Injection, mixing, and flame-holding schemes relevant to one may be useless for another. Alternative scramjet ignition methods will need to be characterized numerically and experimentally for their effects on injection, mixing and combustion processes. For example, PRA is currently investigating Plasma assisted ignition, offering potential safety and reliability benefits over current scramjet ignition methods. Area 2: The influence of the internal flow-path cross-section of the scramjet on limitations in engine operability and combined cycle integration need to be investigated. The influence of corners and of the overall aspect ratio of the flow-path are two issues of interest. The performance and operability benefits of variable geometry needs to be determined. Further, the purpose is to be able to trade these benefits against the difficulty of incorporating movable, hot surfaces within the engine flow-path. It may be desirable to investigate alternatives to our current baseline, JP7 fuel for high speed propulsion. Thermal capacity trades with ignition and stability limits may favor other hydrocarbons for future applications. Evaluate various approaches for solving the cold-start ignition problem in hydrocarbon-fueled scramjets (may include aerated fuel injection, plasma (or other) torch methods, fuel additives, etc.) Both Research and Development areas may require further design and implementation appropriate data acquisition methods for conventional and advanced instrumentation. Foreign sources are not permitted to respond due to ITAR/PL 98-94 requirements and security requirements. A Pre-Proposal Conference will be held on 02 October 2002, from 1300 hours to 1700 hours in building 18, PR Conference Room, Wright-Patterson AFB, Ohio. Foreign sources will not be permitted to attend the conference.
