DRDO Secures Patent for Indigenous BAM-H24 High-Energy Fuel for Advanced Solid Rocket Propulsion

India has secured a new intellectual-property milestone in advanced energetic materials, with the Defence Research and Development Organisation and researchers at the University of Hyderabad receiving a patent for BAM-H24, a newly developed high-energy compound intended for advanced solid-rocket propulsion applications.

The invention carries the technical title N1,N1,N1,N4,N4,N4-hexaethylbut-2-yne-1,4-diaminiumdodecaborane: The Next Generation Solid Rocket Propellant Fuel. Developed by Dr. Muddamarri Hanumantha Rao and Prof. K. Muralidharan, the work covers the synthesis, structural characterisation and energetic properties of the compound designated BAM-H24.

BAM-H24 is rich in boron, hydrogen and nitrogen, elements of considerable interest in high-energy propulsion chemistry. According to the University of Hyderabad, the compound combines strong chemical and thermal stability with relatively low sensitivity to impact and friction. It is also non-hygroscopic, helping it resist moisture absorption during storage and handling.

Researchers expect the material to offer advantages including high specific impulse potential and reduced ignition delay when incorporated into suitable propulsion formulations. BAM-H24 could potentially be employed directly as a solid-rocket fuel component, blended as a high-energy fuel additive or used as a burn-rate accelerator depending on the formulation and propulsion requirement. These remain prospective applications of the patented material rather than confirmation that it has entered an operational missile system.

The development is particularly relevant to India’s continuing effort to improve indigenous solid-propulsion technology. DRDO identifies higher-specific-impulse propellants, boron-based fuel additives, advanced energetic materials and technologies for controlling propellant burn rates among the areas being pursued for future propulsion systems.

Solid motors are widely used in missiles, launch vehicles and other aerospace systems because they can provide compact propulsion, rapid readiness and comparatively simple long-term storage. DRDO’s own historical account describes India’s solid-propellant capability as largely indigenous and notes its extensive application in both launch vehicles and ballistic missile systems.

The BAM-H24 patent does not reveal any specific missile or launch vehicle for which the compound is intended. Its importance instead lies at the materials level: developing a domestically controlled energetic compound with the potential for higher performance, improved storage characteristics and safer handling could provide Indian propulsion researchers with another building block for future solid-motor formulations.

The patent also reflects the growing role of university–DRDO collaboration in high-energy materials research. If BAM-H24 progresses successfully from laboratory characterisation through formulation, motor testing and eventual qualification, it could contribute to the next generation of indigenous Indian solid-propulsion systems while reducing dependence on externally sourced specialised energetic materials.
