The National Aerospace Laboratories (NAL), a constituent of the Council of Scientific and Industrial Research (CSIR), has achieved a significant milestone in propulsion technology by developing advanced Wankel engines in two power categories: a 10-15 kW hybrid Wankel engine and an 80-100 kW Wankel engine. These engines are poised to play a pivotal role in powering Unmanned Aerial Vehicles (UAVs) and cruise missiles, boosting India’s self-reliance in cutting-edge propulsion systems for strategic and tactical applications.
The 10-15 kW hybrid Wankel engine is designed to combine the best of combustion and electric propulsion systems. The hybrid configuration ensures high efficiency, reduced fuel consumption, and extended operational range, making it suitable for lightweight UAVs that require silent operation during critical missions.
On the other hand, the 80-100 kW Wankel engine is a high-performance propulsion system that offers robust power output for larger UAVs and cruise missiles. The compact design of the Wankel engine makes it an excellent choice for these platforms, as it ensures high power-to-weight ratios and enhanced reliability while reducing the overall system weight.
Applications
- Unmanned Aerial Vehicles (UAVs):
- The hybrid Wankel engine is ideal for tactical UAVs used in reconnaissance, surveillance, and border patrolling missions.
- The 80-100 kW engine is suited for medium-altitude, long-endurance (MALE) and high-altitude, long-endurance (HALE) UAVs, enabling longer flight durations and higher payload capacities.
- Cruise Missiles:
- The high-power Wankel engine can be integrated into cruise missile platforms, providing the required thrust for long-range precision strikes while maintaining a low radar and thermal signature due to its compact and efficient design.
Globally, the demand for advanced UAVs and cruise missiles is surging, and propulsion systems like the ones developed by NAL provide India with a competitive edge in this domain. Domestically, these engines can reduce dependence on foreign imports and strengthen India’s defense manufacturing ecosystem.
Moreover, these engines could also find applications in civilian domains, such as power generation for remote areas and hybrid drones for logistics, further enhancing their utility beyond military uses.
