DRDO, UoH researchers develop next-generation rocket propellant fuel

DRDO and University of Hyderabad researchers have developed a next-generation solid rocket propellant fuel called BAM-H24, which has received an Indian patent. The compound offers strong stability and reduced sensitivity, with potential applications in missile systems and launch vehicles.

Hyderabad: In an innovation that will support indigenous defence capabilities, Defence Research & Development Organisation (DRDO) and Advanced Centre of Research in High Energy Materials (ACRHEM), UoH, faculty developed the next-generation solid rocket propellant fuel for missile systems and launch vehicles.

This innovation received an Indian patent from the Patent Office, Government of India. Invented by researchers Dr Muddamarri Hanumantha Rao (ACRHEM) and Prof Muralidharan (ACRHEM and School of Chemistry of UoH) Krishnamurthi, the invention details the synthesis, structural elucidation, and energetic properties of a novel boron-, hydrogen-, and nitrogen-rich energetic compound designated as BAM-H24.

One of the many unique features of the fuel is that it exhibits strong chemical and thermal stability, along with high insensitivity to impact and friction, making handling and storage safer.

According to researchers, the fuel is expected to deliver high specific impulse values and reduced ignition delay, boosting energy efficiency and performance in solid rocket propulsion systems. Further, its non-hygroscopic nature prevents water absorption, preserving propellant integrity under humid or demanding storage conditions.

In addition, the BAM-H24 is expected to function as a solid rocket propellant fuel, fuel additive, or burn rate accelerator in advanced high-energy material formulations.

Providing the possibility of a highly efficient, safer, and reliable solid fuel formulation for missile systems and launch vehicles, this innovation would support indigenous defence capabilities under national self-reliance initiatives, the researchers said.

Since the fuel has reduced sensitivity to accidental impact or friction, it minimises operational hazards for personnel in manufacturing facilities, they added.
