Utilization of Ammonium Dinitramide (ADN) in Propellant Formulations.

摘要

Utilization of the high energy oxidizer ammonium dinitramide (ADN) gives several desirable characteristics when employed in solid propellants. These include non- chlorine combustion products (attractive for applications where hydrochloric acid might contaminate sensitive payload components), facile extraction into water (suitable for water washout/ingredient recovery and/or reuse demilitarization methods), simple methods for destruction (easily converted into the fertilizer ammonium nitrate), and attractive performance and ballistic characteristics. At Thiokol the viability of ADN as a propellant ingredient has been greatly enhanced by the use of additives to stabilize the material and a prilling process to give spherical, defect-free particle morphology, ideal for propellant formulating. The major technical challenge remaining is to reduce the hazards of propellants which contain ADN as the main oxidizer.
