Iranian-Born Engineer Mohsen Bahmani Introduces Propeller-Less Propulsion for Urban Air Mobility

MIAMI - PrZen -- Iranian-born mechanical engineer and inventor Mohsen Bahmani, in collaboration with fellow engineer Mr. Vafaey, has developed and patented a propeller-less propulsion system for next-generation drones, flying taxis, and advanced transportation platforms. The system fundamentally differs from conventional propellers and jet engines while remaining fully compliant with Newton's Third Law of Motion.

Bahmani first gained international recognition at age 17 for inventing the award-winning "Floating Shoes," a water-walking device honored at the Geneva International Exhibition of Inventions. His latest work extends that early focus on unconventional mobility into advanced aerial and multi-modal propulsion.

The propulsion system is protected under European Patent EP 17830806.6, publicly accessible through the European Patent Office (EPO):

Scientific and Technical Overview

The patented system is built around a closed-loop track composed of two straight sections and two semi-circular curved paths. Multiple reaction engines, such as compact electric impellers, circulate continuously through the loop.

During the acceleration phase, engines are electrically accelerated along the first straight section, storing kinetic energy. In the energy transfer phase, centrifugal forces in the first curved section transfer this energy to the looped structure, generating forward-directed thrust. The engines then enter a deceleration and control phase along the second straight path, maintaining stability and counteracting gravity. Finally, during the return phase, the engines traverse the second curved section at reduced speed, completing the cycle.

With multiple engines operating simultaneously in different phases, the system produces continuous, directed thrust that can be mechanically coupled to aerial, terrestrial, or maritime vehicles. The system is not reactionless and operates fully within classical mechanics.

Power Delivery and Design Advantages

Power is supplied wirelessly through electromagnetic induction. A conductive loop energized at approximately 1–3 MHz creates a magnetic field, inducing current in secondary coils within each engine in accordance with Faraday's Law. Reported efficiencies reach up to 90 percent, eliminating physical wiring and reducing wear.

Thrust scales with loop length, enabling adaptability across vehicle sizes. When integrated into eVTOL platforms, the system offers reduced noise, improved urban safety, and slim-profile designs without large exposed rotors.

Applications and Background

The technology is applicable to drones, eVTOL aircraft, automotive and rail systems, maritime platforms, hovercraft, flying cars, space, defense, and industrial transport.

Mohsen Bahmani, educated at the Karlsruhe Institute of Technology (KIT) in Germany, focuses on scalable propulsion technologies aimed at safer, quieter, and more efficient transportation across land, sea, air, and space.
