2 2 Agenda Outline Why PGC? Sample Programs Background Charter, Scope & Objectives Initial Activity Plan Related Committees Membership Roster Working Group Activities Near-term Goal

3 3 Why PGC?: Market Drivers - Aviation & Powergen Fuel costs 15% to 25% of airlines costs Flattening technology curves There is a significant value for technologies that bring 5%+ efficiency improvements Fuel Consumption Source: Aviation and the Global Atmosphere, Intergovernmental Panel on Climatic Change, 1999. Why PGC? 5-15% fuel burn reduction potential for a real PGC-based hybrid engine Lower greenhouse gases Tangirala et al., 2007-TurboExpo, Montreal

4 4 Harper, D., DWP-2011, MBDA Workshop, Bourges, France, 2011 Why PGC?: Performance Advantage of PGC cycle

5 5 Sample PGC Research Programs

6 6 Sample PGC Technology Programs

7 7 Background…Why now? Flattening efficiency curves for Brayton cycle based engines necessitates new modes of combustion to lower sfc. After a decade of research and technology development, pressure gain combustion looks promising for both propulsion and energy applications. Individual facets of pressure gain combustion technologies represented sporadically in the technical committees, but there is no central focus & systems thinking approach. A PC, with its inherent systems point of view, flexibility of approach, and access to a wide range of expertise, offers AIAA such a focus that would broadly benefit the membership. Other international entities, mostly propulsion organizations are ramping up their involvement in pressure gain combustion activities. AIAA needs a clearly defined focal point & should work to become a leader in this growing domain.

8 8 Proposed Charter The purposes of the Working Group to form the Pressure Gain Combustion Program Committee (PGC-PC) are: to function as the AIAA focal point for all pressure gain combustion programs and technologies, and will work integrally across the technical committees to ensure all program areas are represented and addressed, to help develop propulsion community assessment of pressure gain combustion technologies for various applications by organizing special sessions, workshops and panel discussions, and to help develop a holistic, systems level approach to propulsion systems for various applications and provide feasibility assessment to policy makers, govt agencies and OEMs. Draft

9 9 Scope Coordinate and focus PGC activities across the technical committees to develop / support conferences, workshops, position papers, panel sessions and technical sessions Support AIAA public policy forums / initiatives and provide a liaison to the committee Characterize the critical challenges for PGC technologies Identify rapidly advancing & emerging technologies that support propulsion systems using PGC Identify champions for PGC initiatives within AIAA Co-sponsor relevant conferences and events with other professional societies Serve as the focal point and interface between AIAA and the growing PGC community, including DARPA, DOE, ONR, AFOSR, and complementary professional societies.

10 10 Objectives Help shape the vision, direction and policy for future PGC based propulsion systems Provide a forum in which industry, government, and academia can discuss solutions & approaches in an informal, non-competitive environment. Assess, advocate and promote feasible systems-level approach (application dependent) to developing propulsion systems based on PGC. Identify markets and opportunities for funding to develop promising technologies through its members and liaisons, while serving to connect funded programs, market needs, and existing technologies Promote and support conferences, workshops, sessions and technical publications in the area of PGC. Provide efficient knowledge transfer (education) to the AIAA membership Ensure all relevant aspects of PGC technologies are represented in the technical committees and conferences

11 11 Initial Activity Plan for 2013 Provide panel sessions for ASM and JPC – Moving Forward with new propulsion applications (EC* / non- EC sessions?) Provide an annual article for Aerospace America Establish quarterly meeting rhythm…Jan (ASM), July (JPC) Recruit members from technical committees Identify liaison to Public Policy committee Pursue coordination opportunities with other professional societies Develop PGC Technology Working Group portal on AIAA website * Export Controlled

18 18 Appendix

19 19 Sample Technical Committee Responses The interests of the Space Architecture Technical Committee (SATC) include sustainable development, both in space and on Earth. We promote a two-way transfer of building technology and design practice between Earth and space to improve habitat efficiency and reduce environmental impact. We welcome the establishment of a Green Engineering Program Committee. - Space Architecture Technical Committee The technologies that are worked under ISRU have many applications to green engineering, as we are basically all about the reduce-reuse-recycle circle. Especially with a potential shift of focus to Mars, with its CO2 atmosphere, we have many potential terrestrial applications…I think there are several members of my TC that may be interested in your new PC... -Space Resources Technical Committee I am also very keen to work with you and the Green Engineering Work Group. I would like to see a close alliance between the Group and the GTE TC to ensure we leverage our common interests and minimize duplication. Clearly we have much in common, so lets; set up a liaison and think about collabaration on JPC session etc. - Gas Turbine Engines Technical Committee Congrats and welcome aboard! I can't think of any Space Logistics TC suggestions just now, but we will be pleased to work with you. There are surely many areas of overlap and opportunities for collaboration between us. - Space Logistics Technical Committee See…We welcome any support for this conference you can muster -Digital Avionics Technical Committee
