At Black Kestrel our propulsion research goes beyond electric motors, exploring next-generation technologies that could revolutionise electric flight. By advancing Ionic Thrust, Electric Thermal Rockets and our proprietary Electro-Magnetic Reaction Mass Pulse Drive, we aim to push the limits of efficiency, thrust, and endurance for future aircraft and spaceflight applications.
Ionic thrust technology uses electrostatic forces to accelerate ionized air, generating thrust without moving parts. While traditionally limited to low-thrust applications, advances in high-voltage power systems and optimized ionization techniques could make this a viable option for silent, ultra-efficient propulsion in Earth's atmosphere.
The Electric Thermal Rocket (ETR) converts electrical energy into heat to superheat a propellant, creating thrust similar to a traditional rocket but with superior efficiency. By leveraging the high energy output of the Generator Cell, ETR technology could enable high-altitude, near-space operations, and even deep-space missions, with vastly reduced propellant requirements compared to chemical rockets.
Black Kestrel's proprietary Electro-Magnetic Reaction Mass Pulse Drive (EM-RMPD) is an experimental propulsion system designed to generate thrust by electromagnetically accelerating reaction mass in controlled pulses. This concept aims to deliver higher thrust levels than traditional ion propulsion, with the potential for atmospheric and near-space applications. Our focused is on optimising reaction mass acceleration to make this a practical propulsion solution for future aircraft and spacecraft.
