Raphe mPhibr has been reportedly advanced the development and testing of its indigenous next-generation two-stroke engines and high-powered UAV powerplants, combining vertical integration with advanced composites, electronics, and AI to strengthen India’s unmanned aerial ecosystem.

This effort positions the company as a leader in performance, efficiency, and self-reliance for UAV technology.

Raphe mPhibr begins its innovation journey with a simple question: how can propulsion be reimagined for unmanned aerial systems? The answer lies in its pursuit of advanced two-stroke engine technology, designed to deliver higher efficiency, endurance, and adaptability for drones and UAV platforms. Every step forward in engine design represents a leap towards the future of unmanned systems.

The company has invested heavily in indigenous two-stroke engines, leveraging metal 3D printing to reduce weight and accelerate prototyping. These engines are optimised for endurance and payload efficiency, enabling UAVs to fly longer missions with reduced fuel consumption.

Raphe mPhibr’s propulsion program is not limited to small drones; it extends to high-powered engines, such as its 335 hp home-built powerplant for a 1.5-ton Medium-Altitude Long-Endurance (MALE) UAV. This engine marks India’s first indigenous UAV powerplant in this category, directly challenging imported propulsion systems.

Raphe mPhibr’s vertically integrated ecosystem ensures that propulsion is developed alongside other critical technologies. The company designs and manufactures carbon-fibre composites, multilayer PCBs, autonomous navigation systems using SLAM, and ground-control technologies.

This integration allows greater control over performance and manufacturing, reducing dependence on foreign suppliers and strengthening India’s aerospace infrastructure.

The propulsion systems are complemented by AI-enabled UAV swarms, capable of real-time adaptation and peer-to-peer communication. With swarm sizes of up to 100 UAVs and tracking precision of 99.5%, Raphe mPhibr demonstrates how propulsion, electronics, and artificial intelligence can converge to create advanced unmanned capabilities.

These swarms are supported by engines designed for reliability and endurance, ensuring operational success in contested environments.

The company’s MALE UAV project highlights the importance of indigenous propulsion. With a 335 hp engine, the UAV achieves endurance exceeding 30 hours, payload flexibility, and operational capability in high-altitude regions such as the Himalayas.

Compared to imported platforms like the Heron MK-II, Raphe’s UAV offers superior thrust and higher indigenous content, aligning with India’s Make in India defence program.

Raphe mPhibr’s propulsion innovations extend beyond military applications. Its research into fuel-flexible engines explores methane and hydrogen combustion, paving the way for cleaner aerospace technologies.

This dual-use approach supports both defence and civilian energy needs, reinforcing India’s strategic goal of technological self-reliance.

From a simple question to advanced engineering, Raphe mPhibr demonstrates how innovation in propulsion drives the future of UAV technology. By combining indigenous engine development with vertical integration, advanced composites, and AI, the company is building a foundation for India’s next-generation unmanned aerial systems.
