ALUMINIZED ADN/GAP PROPELLANTS -FORMULATION AND PROPERTIES

摘要

The paper presents an overview of the HISP project and focuses on the work performed at ICT concerning AI/ADN/GAP propellant formulation. Spacecrafts are today propelled using chemical or electrical rocket propulsion systems. Electrical propulsion provides superior specific impulse but very low thrust, whereas chemical propulsion provides low specific impulse but high thrust. If high thrust is required, chemical rocket propulsion is thus the only viable alternative. Depending on the propellants used, chemical rocket propulsion systems are divided in three major categories: 1. Liquid propellant rockets (monopropellant and bi-propellant systems) 2. Hybrid propellant rockets (solid fuel, liquid oxidizer) 3. Solid propellant rockets.
