XE-21 ELECTRIC AIRCRAFT

The Black Kestrel XE-21 is redefining what’s possible in electric aviation. Designed for high-altitude, long-endurance missions, this next-generation aircraft is powered by our revolutionary Generator Cell technology, delivering superior energy density and efficiency beyond conventional batteries.

With advanced electric propulsion and an aerodynamically optimized design, the XE-21 will achieve exceptional range and performance while maintaining the reliability and sustainability of an all-electric system. Its advanced energy storage technology will enable longer flight durations, making it a game-changer for scientific research, atmospheric exploration, and future aerospace innovation.

HIGH ALTITUDE PERFORMANCE

Designed for extreme altitudes, the XE-21 can operate at the edge of space, where thinner air demands an optimized aerodynamic design and efficient energy use. Its electric propulsion system remains effective at high elevations, enabling scientific research, atmospheric monitoring, and next-generation aerospace applications.

LOW MAINTANACE

With fewer moving parts than traditional combustion engines, the XE-21's electric propulsion system requires significantly less maintenance and has a longer operational lifespan. This reduces downtime, lowers maintenance costs, and increases overall reliability, making it ideal for long-endurance missions.

ZERO CO2 EMISSIONS

The XE-21 is powered entirely by electric propulsion, eliminating carbon emissions and reducing environmental impact. By leveraging our advanced Generator Cell technology, it achieves clean, sustainable flight without relying on fossil fuels-paving the way for a greener future in aviation.

QUIETER OPERATIONS

The XE-21's electric propulsion produces minimal noise, making it ideal for operations where stealth and low acoustic impact are crucial. This near-silent flight capability is beneficial for scientific observation, environmental monitoring, and defence applications where reducing noise pollution is essential.

LANDING GEAR

The XE-21 features a durable yet lightweight retractable fully electric operated tricycle landing gear system. The electric system provides smooth deployment and retraction of the landing gear, ensuring safe and reliable ground operations

ELECTRIC ENGINES

Powered by advanced ducted fan electric propulsion system, the XE-21's twin electric engines deliver zero-emission, high-efficiency thrust. With instant torque, low vibration, and reduced maintenance requirements, these engines provide quiet and reliable performance.

VERTICAL STABILISERS

The unique twin vertical stabilizer tail design enhances directional stability and control, especially in high-altitude operations. Their design minimizes drag while maintaining yaw and roll manoeuvrability, ensuring the XE-21 remains stable even in thin atmospheric conditions.

WINGS

Designed for maximum lift-to-drag efficiency, the XE-21's 45 degrees swept wings with induced drag reducing winglets are optimized for sustained electric flight and high speed. With superior aerodynamic performance this makes the aircraft ideal for extended research and exploration missions.

ELEVATORS

The XE-21's elevators provide precise pitch control, ensuring stability and responsiveness in both low and high-altitude conditions. Engineered for aerodynamic efficiency, they contribute to smooth handling and optimized energy usage during flight manoeuvres.

COCKPIT AND CABIN

The XE-21's cockpit and cabin are designed for pilot and passenger comfort especially during long-duration missions. The cockpit provides maximum visibility and instrumentation precision, ensuring seamless control at high speeds and high altitude cruise.

FUSELAGE

The XE-21's monocoque (structured skin) fuselage is constructed using steel and aluminium for an optimal balance of strength and weight reduction. This innovative design enhances structural integrity while contributing to the aircraft's high-altitude capabilities and energy efficiency.
