    Engine Design Competition dates


    New engine designs are solicited for the next generation supersonic transport. Entry into service is expected to be 2010 – 2025. This current solicitation is motivated by NASA’s National Research Announcement (NRA) back in 2006 (NNH06ZEA001N, Amendment 6, Task 4.7) for a supersonic transport vehicle. The NRA is calling for an aircraft that is a generation beyond the supersonic business aircraft that is currently being considered and smaller than the supersonic airliners of past NASA programs (i.e. High Speed Civil Transport). The baseline propulsion system is based on the engine modeled in NASA/CR-2010-216842. The candidate engines must demonstrate at least 5% improvement in TSFC (at specified thrust levels) and substantiate weight savings. Furthermore, both cruise emissions goal and noise constraint (represented by exit jet velocity) are imposed.

    Data for a generic baseline model of the baseline power plant is supplied. Responders should use the provided typical, multi-segment, mission to address the design improvements, especially for design point and off-design engine operations. The performance and total fuel consumption of the candidate engine should be estimated for critical mission points and stated clearly in the proposal. Special attention should be paid to engine mass, dimensions and integration with the aircraft.
