The Defence Research and Development Organisation (DRDO) is reportedly in the early stages of developing a new class of Beyond Visual Range Air-to-Air Missiles (BVRAAM) that will follow the Astra MkIII, one of the most advanced air-to-air missiles in India’s arsenal. According to reports from idrw.org, the conceptual studies for this upcoming missile system are already underway, with the development focusing on cutting-edge technologies that will push the capabilities of the Indian Air Force (IAF) to new heights.
Among the various technologies being considered for the next-generation BVRAAM is the Triple Pulse Solid Motor. This innovative motor design is viewed as a potentially cost-effective alternative to the SDFR-based propulsion system. The Triple Pulse Solid Motor aims to deliver the same range and performance as the Astra MkIII, but in a much more affordable manner, thus making it a promising candidate for India’s future BVRAAM program.
The Triple Pulse Solid Motor concept involves a rocket motor divided into three segments or pulses. Each pulse can be ignited sequentially to provide bursts of propulsion at different stages of the missile’s flight. This technology aims to extend the range and improve manoeuvrability by optimizing fuel consumption.
By staging the motor’s operation, the missile can achieve greater distances without the need for the continuous thrust of a ramjet, which is more complex and expensive. Manufacturing and maintenance of solid-fuel motors are generally less costly than ramjet systems, making this an attractive option for scaling production. The ability to control propulsion allows for tactical advantages in different aerial combat scenarios, potentially offering better performance in terms of speed changes or trajectory adjustments.
This approach could offer a highly capable missile system without significantly increasing costs, making it an attractive option for the DRDO and IAF. However, as idrw.org has noted, while Triple Pulse Solid Motor technology is being considered, it has not yet been finalized. The missile program is still in the conceptual stages, and the technical parameters and baseline requirements are still under discussion.
