Abstract
The invention relates to a propulsion device for flying objects (aircraft, manned rockets, spacecraft) that operates on novel principles. Rather than conventional reaction-thrust systems using ejected propellant, this device controls "space curvature components through strong magnetic energy, utilizing space distortion forces generated within space itself as propulsive force." The device comprises magnetic energy generation means producing spherical magnetic fields from superconducting materials, and magnetic control means that locally modulates space curvature in quasi-antisymmetric patterns, converting gravitational-equivalent space distortion forces into thrust.
Claims (Two Inventions)
First Invention Claims
A flying object propulsion device comprising:
- A spherical superconducting magnet disposed inside a sphere of superconducting material
- Paired auxiliary superconducting magnets generating opposite-polarity fields in left and right hemisphere regions of the sphere
- Magnetic control means varying excitation pulse frequencies of the auxiliary magnets
The auxiliary magnets create an asymmetric multipole field configuration within the superconducting sphere. By varying the pulse frequency, the space curvature around the sphere is modulated, and the resulting quasi-antisymmetric distortion forces provide directional propulsion.
Second Invention Claims
A system employing:
- Liquid metal storage containers
- Spherical blanket containers (for liquid metal containment)
- Paired superconducting magnets for initial field generation
- Pulsed laser sources for magnetic flux freezing and compression effects (flux compression via laser-induced shock)
- Exhaust pumps for coolant management
The system enables continuous pulse magnetic field generation reaching "from several hundred thousand to tens of billions of Tesla" through laser-driven flux compression — a process analogous to magnetized target fusion where a laser pulse compresses a magnetized plasma to transiently achieve ultra-high fields.
Description / Specification
Patent Figures
Figure 11: Top-down view of a spherical object (component 33) showing concentric electromagnetic field rings radiating outward — the classic dipole field pattern of a magnetically charged sphere, consistent with a superconducting sphere in the Meissner state expelling magnetic flux into its surroundings.
Figure 12: Internal cross-section of a disc/saucer-shaped craft (outer shell labeled 45). Two bar magnet assemblies (41 and 43) are positioned at the center of the disc with pole pairs S-N and N-S respectively, and field lines B1 and B2 labeled. The magnets are horizontal with combined field lines creating a complex multipole pattern extending to the shell wall.
Figure 13: Side view of component 33 with field lines deflected on one side by a parallel plate arrangement — the Meissner effect: a superconductor expels flux on the side facing the external magnet, forcing field lines to curve away from the superconductor surface. By positioning the superconductor asymmetrically relative to the field source, the net force on the superconductor has a directional component — propulsion.
Theoretical Framework: Riemannian Geometry and Space Curvature
The specification extensively develops a theoretical framework based on Riemannian geometry:
Space Structure: Treats space as an infinite continuum governed by Riemannian geometry where local curvature generates distortion fields (analogous to the way mass-energy curves spacetime in general relativity).
Curvature-Force Relationship: "Space curvature is space itself generating surface force" — the curvature tensor components R^i_jkl generate an effective pressure field in the curved region, creating unidirectional acceleration zones for objects within the field.
Magnetic Field–Space Curvature Coupling: The specification presents the key quantitative claim:
"20 million Tesla magnetic field generates equivalent space curvature to Earth's 1G surface gravity"
In Einstein's general relativity, the energy density of the electromagnetic field contributes to the stress-energy tensor T_μν which sources spacetime curvature:
G_μν = (8πG/c⁴) T_μν
For an electromagnetic energy density u = B²/(2μ₀), at B = 2×10⁷ T:
u = (2×10⁷)²/(2 × 4π×10⁻⁷) ≈ 1.6×10²⁰ J/m³
This energy density is comparable to nuclear matter density, and at this scale the electromagnetic contribution to T_μν would indeed produce measurable spacetime curvature. The question is whether such fields can be generated and confined in a controlled manner — which is where the laser flux compression mechanism of the Second Invention enters.
Propulsion Mechanism
The device achieves propulsion through:
-
Quasi-symmetric distortion: Creating asymmetric space curvature zones — curved region on one side vs. flat region on the other — around the spacecraft.
-
Pulse control: Rapidly cycling the magnetic field ON/OFF so curved space transitions to flat space, decoupling the object from the field during the transition phase. The object moves into the flat region before the next pulse.
-
Volume force application: Unlike conventional thrusters (where thrust is applied at a surface), thrust from space curvature modification penetrates the entire spacecraft volume equally, theoretically preventing inertial stress on occupants during acceleration. This addresses the "why don't UAP occupants experience g-forces" question directly.
-
Continuous acceleration: Pulse repetition frequency control enables variable acceleration from microgravity to claimed 100G acceleration.

Second Invention: Ultra-High Magnetic Field via Laser Flux Compression
The Second Invention addresses the field generation problem: achieving tens of millions of Tesla. Standard superconducting magnets are limited to ~45 T (continuous) or ~100 T (pulsed). To reach 20 million T requires a different approach.
The mechanism: pulsed laser illumination of a spherical blanket containing liquid metal and frozen magnetic flux. The laser-induced shock wave compresses the conducting liquid metal shell, rapidly decreasing its volume and (by magnetic flux conservation in a conductor) increasing the enclosed magnetic flux density:
B_final = B_initial × (R_initial/R_final)²
For a factor of ~1,000 compression in radius (achievable in shock compression):
B_final = B_initial × 10⁶
Starting from B_initial = 100 T (achievable with pulsed magnets), the laser compression yields B_final = 10⁸ T — approaching the claimed range. The compressed field exists for the duration of the compression pulse (microseconds), but at the stated pulse repetition frequencies, sustained propulsive effects are claimed.
NEC Corporation: Defense Electronics Significance
NEC is one of Japan's largest defense electronics contractors, supplying command-and-control systems, radar, and satellite communications to the Japan Self-Defense Forces. A patent on superconducting flying object propulsion filed by NEC in 1991 — during the peak of Japan's high-temperature superconductor research boom (YBCO superconductors discovered 1987 by Bednorz and Müller, Nobel Prize 1987) — indicates NEC was treating this as potentially militarily or commercially realizable technology.
The GB 1992 international filing further indicates international IP protection intent by a major defense electronics corporation.
Minami's Subsequent Research Program
Following this 1991 patent, inventor Yoshinari Minami published extensively on "space drive propulsion" through NEC and later independently. His subsequent theoretical framework extends beyond Meissner-effect force to full metric engineering — using electromagnetic field configurations to locally modify the spacetime metric tensor g_μν, effectively creating a curved spacetime bubble within which the craft moves along a geodesic. This connects the Minami research program to the Alcubierre (1994) metric engineering class.
