Challenges and Proposed Solutio• Challenges to Alternative Fuel Approval P

– Cost/duration of fuel approval process

• Fuel quantities for rig/engine tests

– OEMs uncertainty over effects of novel fuel com

chemistry on combustor operability

• Proposed Solution

– Develop generic fuel composition/chemistry eval

methodology

• Standardized rig/lab tests• Chemical kinetic/combustion modeling

– Collaborative OEM/university/federal effort

Benefits • Streamlines current ASTM approval process

– Fewer rig/engine tests

• Eliminates duplicative OEM testing

– Reduces costs and accelerates schedule– Increases throughput of new fuel approvals

• Reduces fuel quantities required for approval

– Replace/reduce combustor/engine tests with rig tests/mod

• Reduces engine OEM risk/uncertainty

– Provides greater understanding of fuel chemistry effects o– Provides greater understanding of the performance of nov

chemistry

– OEM participation in development of tests and models

• Improved industry modeling and design tools

– Supports compositionally-based fuel approvals– Supports identification of acceptable fuel composition bou

future engine designs

Program Development and Status 

9

• Consulted with engine OEMs on the plan development

 Conducted three group telecons with OEMs Secured 5 whitepapers from OEMs on program objective and approach 

• Conducted a webinar to educate ASCENT COE community on 

objectives and forthcoming solicitation

• Attended by 64 participants

• Awarded all 5 OEMs contracts through AFRL in the total amou

($500K from AFRL and $500K from AEE)

• Formed program Steering Committee comprising of Federal a

representatives

 Steering Committee co-chairs: Mel Roquemore and Mohan Gupta  Steering committee will also include ASCENT PIs of selected proposals

• Timeline:

 July 8, 2014: Released 6 Requests for Notice of Intents to ASCENT COE July 28, 2014: Received 20 proposals covering all 6 areas A panel of federal members reviewed all proposals In process to notify the selected teams
