Fuel burn reduction 70%, same range, speed, airport infrastructure. Technology: Hybrid Wing Body, Fully distributed 50MW, Superconducting, 7500V, power system
Empirical Systems Aerospace ECO-150R
Depending on the underlying technology assumptions performance ranges between matching and significantly exceeding current aircraft fuel burn. Technology considered ranges from superconducting electrical machines cooled with liquid hydrogen to conventional machines at various technology levels. The ECO‒150R, which utilizes midterm electrical machine technology.
- NASA STARC-ABL: fuel burn reduction, same range, speed, airport infrastructure. Same turbine/airframe technology, Advanced 2-3MW power system, BLI, turbogenerator integration.
Boeing SUGAR Freeze
- Boeing SUGAR Freeze: fuel burn reduction 56% for 900 mile mission, utilizes a truss-braced wing combined with a boundary-layer ingesting fan in an aft tail cone to maximize aerodynamic efficiency. The aft fan is powered by a solid oxide fuel cell topping cycle and driven by a superconducting motor with a cryogenic power management system.
|Airframe/propulsion remains relatively decoupled.|
