Abstract

"FIELD: heavier-than-air flying vehicles. SUBSTANCE: craft includes case 1 on whose surface layer 2 made from superconducting material is applied and electric insulators 3 are mounted for superconducting winding 4 with sections of electromagnetic shields 5 located together in hermetic casing-fairing 6. EFFECT: enhanced efficiency. 2 dwg."

Structural Description

The Figure 1 inline diagram shows a horizontal cross-section through the craft — a thin horizontal disc or flattened ellipsoid with the superconducting layer (2) wrapped around the exterior of the central case (1). The superconducting winding (4) is arranged in sections with electromagnetic shields (5) that isolate adjacent winding sections from each other's magnetic field, preventing field cancellation between sections.

Physics Mechanism: Superconducting Electrodynamic Lift

The physical principle is superconducting electrodynamic lift. A Type II superconductor in the Meissner state expels magnetic flux from its interior; if the craft's superconducting skin is brought into proximity with an external magnetic field (Earth's geomagnetic field, or a ground-based field source), the mutual repulsion between the flux-expelled region and the external field produces levitation force.

The stored persistent currents in the superconducting winding create a large magnetic dipole moment m that interacts with the external field gradient ∇B according to:

F = ∇(m · B)

The advantage of superconducting winding over conventional electromagnets for this application: once the persistent current is established at operating temperature, zero electrical power is required to maintain it. The craft's propulsion power consumption is limited to what is needed to control the current distribution (via electromagnetic shield sections acting as flux gates), not to maintain the levitation field itself. This is the thermodynamic basis for the "unlimited reserve" claims associated with superconducting propulsion systems.

Historical Context

The 1993 Russian filing by a private inventor reflects the explosion of unconventional technology patents in the immediate post-Soviet period, when previously classified research was partially declassified and inventors previously constrained by Soviet secrecy could file civilian patents on technologies developed within the defense system.

The electromagnetic shield sections (component 5) are the key engineering innovation: they allow the persistent current distribution in the winding to be actively reconfigured, enabling dynamic control of the craft's magnetic dipole moment direction and magnitude. This is the control mechanism for attitude and thrust vector, implemented without any moving mechanical parts.
