Abstract : A cast composite propellant based on a HTPB binder was developed to meet the ballistic and physical requirements of the LANCE igniter grain. Formulation parameters were correlated with propellant burn rate and mechanical properties, and 1-gallon mixes were made to provide grains for a feasibility demonstration. The propellant was scaled up to a 20-gallon mixer, and grains were prepared for a prequalification demonstration task. Propellant performance in the 26-shot demonstration firing series was completely successful. The propellant is considered to be ready for qualification in the LANCE igniter.
