Design Tools for Implementing Advanced Augmentor Ignition Systems Navy SBIR FY2015.1 Sol No.: Navy SBIR FY2015.1 Topic No.: N151-016 Topic Title: Design Tools for Implementing Advanced Augmentor Ignition Systems Proposal No.: N151-016-0579 Firm: Creare LLC 16 Great Hollow Road Hanover, New Hampshire Contact: Darin Knaus Phone: (603) 643-3800 Web Site: http://www.creare.com Abstract: Reliable ignition is critical to the operational performance of augmented military engines. Augmentors must reliably ignite when thrust is needed or system (and pilot) safety could be compromised. Augmentor ignition is particularly challenging relative to other combustion systems because the ignition system must function over an extremely wide range of conditions. Advanced igniter technologies offer the potential for increased reliability and durability, but implementing these technologies in an engine is difficult because there is a lack of analytical tools that can aid in their design, optimization, validation, and control. In the proposed effort, Creare is teamed with a leading developer of an advanced augmentor ignition system. We will work with our collaborator to develop analytical tools that will enable their technology to be used in existing and future engine designs. The analysis strategies will be applicable to a broad range of other advanced ignition technologies as well. In Phase I, we will demonstrate the basic features of our modeling strategy and compare the results with a limited set of existing ignition data provided by our collaborators. In Phase II, we will enhance our modeling tools and validate them against an expanded set of data from our collaborator's novel igniter system. Benefits: Technology derived from this research program will lead to the development of improved ignition systems for augmentors. This technology will enhance the performance and operational reliability of augmented jet engines. Ignition systems are particularly well suited for retrofit, and thus new designs could be used for both future and legacy systems. In the commercial sector, technology developed under this research program could be applied to any combustion system involving spark ignition, most notably internal combustion engines. Return
