So What Charts


Mission Envelope Capture

More %envelope expansion possible on manned systems due to age of SOA baselines compared to SOA UAVs

New UAV platforms (eg. tandem fuselage) or qualified operations (eg. mid-air refueling, rotations with data-link x-fer, etc.)

Solar-Regenerative for endurance above ~60 hours; but limited in Solar latitude, altitude, and seasonal operations


DoD HEETE Program goals

NASA funded Programs (year 2010, 2025)

Red lines represent existing propulsion on platform is 10% of OEW; Blue lines represent 50% of OEW


TPE331-10

PW TF33

CFM56

GE F118

RR AE3007


  • 10% improvement to most pre-1985 engines by capitalizing on existing SOA benefits

  • 5% relative to SOA by 2010

  • 9% relative to SOA by 2025
