About
Busek’s BHT-1500 is a 2kW-class Hall Effect thruster that incorporates an innovative center-mounted cathode. This propulsion system is designed for high efficiency and performance, utilizing xenon, krypton, and iodine propellants. Key design features include a two-piece “composite” anode and a shortened dielectric channel, differentiating it from other SPT designs. The internally mounted cathode offers several advantages, such as improved performance, reduced sensitivity of performance to cathode flow rate, and more efficient cathode-plume coupling. Additionally, the thruster exhibits less sensitivity to vacuum facility background pressure and reduced plume divergence. The BHT-1500 provides class-leading efficiency across a wide range of throttle points, with ample thermal and magnetic margin for high-power operation, making it a flexible solution for small to medium class satellites. Its design minimizes erosion through a virtual magnetic field wall, extending its life beyond the typical requirements of GEO satellites. The BHT-1500 thruster system operates in two distinct modes: an orbit-raising mode, which produces over 120 mN of thrust with 1,700 seconds of specific impulse at 1,800 Watts of power, and a station-keeping mode, delivering more than 100 mN thrust and 1,900 seconds of specific impulse. Independent testing at The Aerospace Corporation demonstrated that the thruster achieves 10% higher specific impulse and 15% higher thrust efficiency compared to its nearest competitive HET product, potentially leading to significant launch mass savings for medium-class GEO communications satellites or increased revenue through added mass capabilities.
