- 16 - Field Emission Electric Propulsion (FEEP) Thruster • Very High Isp ≈ 6000 to 10000 s. • F = 10 µN to 2 mN • Cesium, Rubidium, Indium. • Efficiency = 98% - (Ion~30%; PPT~17 • Self contained propellant reservoir. • No moving parts.
- 17 - New Approaches in Advanced Propulsion: Solar-Thermal Rockets Schematic of Solar-Thermal Propulsion reflector FUEL (Courtesy of SNECMA) Heat exchanger thrust chamber Possible application for future orbit transfer vehicles Concept: Solar energy is concentrated on a heat exchanger by using mirrors or lenses. E.g. liquid hydrogen propellant is passed through a heat exchanger, reaching very high temperatures up to 2500 K, before expanding through a nozzle. By this, solar-thermal rockets make use of the limitless power of the sun to produce relatively high thrust, F, with high exhaust velocities, ve: - F = 5 to 10 N continuous for 70 kW (solar power) - ve ≈ 8000 m/s Basic engineering problems limit thrust levels due to limit in heat transfer from heat exchanger to propellant. In addition, the deployment and steering of large mirrors to collect and focus the solar energy presents an operational challenge. Status: Several concepts for solar-thermal propulsion systems have been proposed, however, so far none have been tested.
