Compared to traditional propulsion, High Performance Green Propulsion (HPGP) provides higher specific impulse and higher propellant density, which results in increased performance.

The propellant is based on ADN (Ammonium DiNitrimide) and is considerably less toxic, non-carcinogenic and simpler to handle than hydrazine. The architecture of HPGP propulsion systems consists of COTS (Commercial Off The Shelf ) components with extensive flight heritage. This enables a simplified transition away from hydrazine, and allows the overall mission cost to be reduced.

The people behind this innovation are found at Bradford ECAPS, a company in the AIAC Group. On this website you will find more information about our HPGP technology and the many benefits it provides.

HPGP provides numerous advantages over hydrazine

Allows for an extended mission, or use of a smaller propellant tank

Non-hazardour fueling operations allow for a shorter launch campaignINCREASED RIDESHARE OPPORTUNITIES
Non-interference of secondary payloads with a primaryHYDRAZINE-FREE LAUNCH VEHICLES
Through the replacement of current hydrazine systemsREDUCED COSTS
On the Prisma mission, a 2/3 cost savings was realized for HPGP propellant, transportation and fuelling operations over the hydrazine system as flown on the same satelliteNEW OPPORTUNITIES
Improved safety, simplified handling and reduced costs allow for the inclusion of liquid monopropellant propulsion systems on university designed satellites
