Expanding the ADN-Based Monopropellant Thruster Family

, 2009
The development of High Performance Green Propulsion (HPGP) was initiated with the goal of meeting the requirements for future satellite missions. The HPGP technology includes a storable monopropellant blend based on Ammonium DiNitramide (ADN) and a thruster with a high-temperature resistant thrust chamber and catalyst. After more than 10 years of R&D,
