About
The BHT-200 is a high-performance and mature Hall effect thruster with significant flight heritage, having flown aboard the Air Force Research Laboratory’s TacSat-2 and FalconSat-5 satellites, and currently operating on-orbit on the FalconSat-6 satellite. It holds the distinction of being the first US-designed and US-built Hall Effect thruster used in-space on operational satellites. The thruster is extensively studied, with numerous technical papers and journal publications detailing its performance and characteristics. Busek offers the BHT-200 as a complete and fully integrated Hall Effect thruster system, which can include a cathode, power processing unit (PPU), digital control unit (DCU), and propellant management systems. The system components are a blend of commercially sourced parts with established flight heritage and in-house produced assemblies and electronics, optimized for maximum performance and lifetime. Over 20 units of the BHT-200 have been manufactured and delivered for various characterization studies, plume analyses, clustering efforts, and modeling. Busek has also delivered iodine-compatible versions of the thruster for the MSFC iSat mission, demonstrating its versatility with different propellants.
