BIT-3 RF Ion Thruster — Busek The 56-75W input propulsion system utilizes a 2 5cm diameter grid RF ion thruster (BIT-3) and a micro RF cathode (BRFC-1) as the neutralizer The thruster’s unprecedented performance produces thrust up to 1 1 mN and specific impulse up to 2,150 seconds
Flight Development of Iodine BIT-3 RF Ion Propulsion System . . . - Cal Poly 95% efficient drain voltage regulator, the RF amp would have an overall efficiency of 90% (bus voltage in → stable RF power out), a remarkable result! BIT-3 system operates at 55-75W draw and can provide >2km s deltaV to a 6U 14kg CubeSats; let’s think about taking CubeSats to Mars, Europa or asteroids!
Preparation of Papers for AIAA Technical Conferences Abstract: A mission-enabling, iodine-fueled mini RF ion thruster was developed for CubeSat applications The thruster, designated as BIT-3 for its 3cm diameter grids, is capable of delivering variable Isp and thrust of 3200sec and 1 35mN respectively at the designed power of 60W
Busek Propulsion Systems - NASA BIT-3 flight hardware undergoing final preparation for delivery; presently booking orders for 12 month delivery Multiple deliveries of complete integrated systems; thrusters, cathodes, PPUs, feed systems tank, harness, brackets; system hot-fire acceptance tests
The First All-Iodine Electric Propulsion Systems Launched by Busek . . . The BIT-3 iodine thruster system is capable of generating up to two kilometers per second (4,474 m p h ) of delta-v for cubesats, opening the possibility for small spacecraft to complete a range of missions previously reserved for large, high-cost satellites
All-Electric CubeSat Propulsion Technologies Busek BIT-3 RF Ion Thruster Performance Adaption of Iodine Technology by Busek’s Mini RF Ion Thrusters (Engines) Iodine stored as a solid low pressure, high density propellant storage The BIT series thrusters (1-7cm sized) are inherently iodine compatible The 3cm BIT-3 thruster is the world’s first gridded ion thruster using iodine
