Quantum Dynamics Enterprises, Inc. (QDE) has announced that the United States Patent and Trademark Office (USPTO) has granted U.S. Patent No. 12,424,887 for its revolutionary Centrifugal Impulse Drive (CIDTM). This marks a significant advancement in the realm of space propulsion as it is the first mechanical propulsion system that can generate thrust without the need for propellant or exhaust gases.
The CIDTM utilizes a sophisticated arrangement of rotating magnets combined with dynamic balancing mechanisms to transform centrifugal energy into consistent, directional thrust. Unlike conventional electric or chemical thrusters, the CIDTM operates without any onboard propellant, allowing spacecraft to maneuver indefinitely while consuming minimal power.
“This patent secures Quantum Dynamics Enterprises” leadership in the field of mechanical propulsion,” stated Harry P. Sprain, CEO/CTO and inventor of the CIDTM. “It validates years of research and testing and represents a foundational leap toward sustainable, long-duration space operations.”
The CIDTM technology has undergone independent testing at the Georgia Institute of Technology, where engineers conducted experiments to assess dynamic motion, balance, and thrust direction. These tests confirmed measurable and repeatable outcomes that align with theoretical expectations.
Further validation emerged from advanced computational modeling performed by Dr. Shakeeb Bin Hasan (Ph.D.), whose finite-element simulations mirrored laboratory results, demonstrating the system”s capability to produce continuous mechanical thrust through controlled rotation and vector detuning. These developments confirm the CIDTM as the first mechanically driven propulsion system capable of generating thrust without any exhaust or reaction mass, a breakthrough that could transform orbital station-keeping, satellite longevity, and deep-space maneuvering.
“This is the first propulsion method that can be completely sealed from the space environment, requiring no fuel and producing no emissions,” Sprain remarked. “It”s a game changer for sustainable, reusable spacecraft systems.”
In addition to securing this patent, Quantum Dynamics Enterprises has initiated the process of filing international patent applications under the Patent Cooperation Treaty (PCT) to safeguard the technology in crucial global markets, paving the way for future licensing and commercial partnerships.
Quantum Dynamics Enterprises, Inc. is a U.S.-based aerospace firm focused on pioneering mechanical propellant-less propulsion technologies for satellites and spacecraft. Founded by inventor and CEO Harry P. Sprain, QDE is committed to developing and commercializing the Centrifugal Impulse Drive (CIDTM), the first propulsion system capable of generating continuous mechanical thrust without fuel or exhaust. With backing from U.S. and international patents, QDE aims to provide sustainable and scalable propulsion solutions for the next generation of space vehicles.
