What is it about?

Aluminum is commonly used to increase solid rocket propellant performance. We test a new propellant additive, investigating performance and combustion characteristics. It is found to reduce unwanted combustion products with similar performance to aluminum-based propellants.

Why is it important?

This new additive reduces unwanted combustion products, including hydrochloric acid, produced by common rocket propellants. This research verified these effects, and compared the performance and combustion behavior to standard propellants to determine if these propellants may be more beneficial than current propellant formulations.
