Goal

Provide aircraft lift and thrust by driving air in cycloid trajectories and creating a low-pressure (vacuum) region beneath the vehicle.

Problem

Low efficiency of conventional helical propellers and the need for a propulsion method that can generate lift without high fuel consumption.

Concept Summary

A rotating crown-shaped propeller consisting of multiple concentric rings with angled blades draws air from the center and ejects it radially, creating cycloid air trajectories. The crown is mounted over a porous surface on the fuselage, producing a vacuum (low-pressure) region that pulls the aircraft forward and upward. The design also incorporates Coanda-effect flow-guiding surfaces.

Detailed Description

The system uses a crown-shaped rotational device with peripheral speed around 396 m/s. The central axle is connected to spokes that form a vacuum chamber. Air is drawn into the central space and expelled through blade-shaped elements arranged on several rings. The blades are set at angles between 45 deg and 75 deg , each with a 6 deg tip arc and a 20 deg body arc. A porous surface on the aircraft's underside creates a boundary-layer suction (vacuum bell) that enhances lift. The device is claimed to work for take-off, landing, horizontal flight in the troposphere, and, with additional electro-kinetic/MHD methods, for upper-atmosphere or space flight.

Principles

  • Cycloid air trajectory
  • Vacuum (low-pressure) generation
  • Coanda effect
  • Porous surface suction

Scientific Domains

Aerodynamics Fluid Mechanics Mechanical Engineering

Materials

  • Metal alloy (blades and crown)
  • Porous material (fuselage surface)

Mechanisms of Action

  • Central air intake
  • Radial evacuation through angled blades
  • Creation of low-pressure region under fuselage
  • Thrust from cycloid-sh air ejection

Applications

  • Aircraft propulsion
  • Vertical lift / VTOL
  • Atmospheric flight

Claimed Performance

Capable of providing lift and propulsion for small discoidal aircraft (e.g., foo-fighters) and larger Haunebu-type vehicles; specific thrust or efficiency figures are not provided.

Experimental Evidence

Historical patents (RO 21370, 1932; FR 545789, 1933) and wartime reports describe prototype devices built in Germany and Romania; no quantitative test data are presented.

Limitations

  • No quantitative performance data
  • Unverified claims of vacuum generation
  • Potential material and manufacturing complexity

Red Flags

  • Claims of vacuum-bell propulsion without published measurements
  • References to secret wartime technology and alleged MHD space propulsion
  • Lack of peer-reviewed or independently replicated data
