Basic Statement of Objectives, “Dual Mode Ramjet (DMRJ) Design Maturation”

Overall Objectives: The objectives of this project are to mature a preliminary dual mode ramjet (DMRJ) design to a critical design level, construct the DMRJ test article, and perform both direct connect (DC) and integrated free-jet testing. The critical design of the DMRJ will constitute Phase 1 of this project; the construction and DC testing is Phase 2; Phase 3 of the program will include integrated free-jet testing. The DMRJ is desired to provide flow dynamics associated with a non-physically throated combustion system in support of an inlet test. The long term goal beyond this project is to have a test bed capability to develop critical path technology for advanced propulsion systems.

There are several technical challenges that will need to be addressed to achieve the stated objective:

- Low-Pressure Ignition o Technologies enhancing our ability to design and build a DMRJ that can operate with hydrogen or hydrocarbons at challenging ignition conditions without the use of silane or other restricted energetics. It is desirable that this system can control combustion such that the shock train position in the isolator is controlled to a specific location.

o An ignition system that is capable of acting as a gas generator in order to control shock train location if conditions don’t permit sustained combustion.

- Affordability o Technologies and techniques that improve the ability to design DMRJ combustors for affordability and manufacturability. It is desirable to explore designing hardware that can be used for both DC and freejet testing such that there are overall project savings.

- Geometric Constraints o Technologies that allow reduced-weight hardware that can meet mold-line packaging requirements. For this project, inlet hardware, test article support hardware, and integrated nozzle design for the free-jet test already exist; the DMRJ must meet all integration requirements of the free-jet model and of the associated free-jet test facility. Additionally, the DMRJ design will be subject to strict free-jet facility-driven weight requirements.

- Test Ability o Technologies that improve the overall capability of a DMRJ to support research activities, to include:

Increased run-times capable of supporting integration research objectives.

Total lifespan that can support activities as an advance propulsion test bed.

Durable instrumentation package that can provide research quality data.

Security Operations Security (OPSEC) must be an integral part of our daily activities. As we maintain security on our future technologies that are vital to national interest, we must recognize and prepare for the threat poised against our technology. Department of Defense policies mandate a high degree of security throughout the acquisition process. However, heightened security awareness and threat-based countermeasures are particularly essential during the research and development phase when our technology is most vulnerable to espionage, sabotage, or exploitation. It is the obligation of each employee or persons involved on this contract be constantly aware of and strictly adhere to security requirements designed to protect sensitive unclassified and other information and resources produced by acquisition, research and development, and technological security efforts outlined in this SOO. The

FA8650-17-S-2002, Call 001 Attch 1 contractor shall ensure employees receive training and follow appropriate Operations Security (OPSEC) measures during the performance of the contract.
