Ultra-quiet eQ engines unlock new capabilities
Electric Quiet propulsion technology enables drones and aircraft to fly 10-20x lower than current state of the art solutions without being heard by humans, or dogs.
Integrate tightly, deploy quickly
Our world-class engineers have pioneered a multidisciplinary design framework that allows for rapid development, reducing integration timelines by more than 75 percent. We integrate our propulsion while balancing various design considerations including:
Aerodynamics
Acoustics
Economics
Mass Properties
Mechanical Design
Payload
Performance
Powertrain
Outspeed and overmatch
Whisper’s propulsion enables ultra-quiet flights with greater efficiency at higher speeds. This opens the door to new C-UAS defense drones, multi-mission CTOL jets, high speed VTOL aircraft, and more.
Ultra-quiet ISR drone
Our team designed, built, and flew a custom Group II demonstrator drone in eight months to validate our propulsion. The drone showcases the ultra-quiet performance of our eQ engines and our ability to integrate them optimally for ISR, SIGINT, and EW missions.
