Pinaka Mk-I & Mk-II Solid Propellant
Pinaka Mk-I & Mk-II rockets use a high-energy solid composite propellant designed for Indian Army artillery. This twin-cartridge, smokeless or low-smoke propellant provides high thrust for rapid firing and long-range engagement of area targets, reaching distances of 45–75+ km.
Chemical Formula & Composition:
- Oxidizer: Ammonium Perchlorate (NH4ClO4).
- Fuel/Binder: Synthetic rubber such as Polybutadiene Acrylonitrile (PBAN) or Hydroxyl-Terminated Polybutadiene (HTPB).
- Metal Fuel: Aluminum powder (Al) for increased energy output.
Description:
The solid composite propellant is cast as grains loaded into a twin-flow motor tube. It is engineered to operate under high pressure and deliver a fast, reliable burn. The propellant system is complemented with silica phenolic lining for heat resistance, wrap-around fin assemblies for stability, and a convergent-divergent nozzle for optimal thrust and trajectory control.
Use:
- Propulsion for 214 mm Pinaka rockets launched from multi-barrel rocket launchers (MBRL).
- Engagement of enemy troop concentrations, artillery positions, and soft targets.
- Provides high-thrust, long-range, and fast-reaction firing capability in battlefield scenarios.
