How It Works

The Rear Field coils are field-shaping coils mounted on the suit's back and flanks. They create a structured magnetic gradient in the near-field (0.05–0.30 m) that gives propulsion force its directionality and efficiency.

Think of them as the magnetic equivalent of a rocket nozzle — propulsion coils provide force; rear field coils shape and direct the thrust vector.

Proprietary Design Principles

JRAD Magnetic Flight Systems & Technology — Patent-Pending Claims

PDP-001

Self-Generated Field Architecture

The JRAD Magnetic Propulsion System generates its own localized magnetic field architecture through an integrated array of electromagnetic coils embedded within the flight suit structure. The propulsion and maneuvering forces are derived entirely from fields created, shaped, and controlled by the system itself. The system does not rely upon, interact with, or require any external magnetic field source — including but not limited to planetary magnetic fields, ground-based infrastructure, or ambient electromagnetic environments — for the generation of lift, thrust, or directional control.

Design Implication The JMPS operates as a self-contained propulsion platform. Operational capability is independent of geographic location, altitude, or proximity to ferromagnetic structures.

PDP-002

Fixed-Envelope Field Geometry

The magnetic field generated by the JMPS coil array constitutes a spatially fixed envelope whose dimensions, shape, and intensity are determined exclusively by the coil configuration and operating current. This field envelope does not expand, propagate, accumulate, or persist independent of the source. The envelope maintains a constant spatial geometry relative to the flight suit and translates rigidly with the system during flight operations.

Design Implication Field envelope dimensions are design constants, not variables. Safety zone boundaries are fixed and predictable at all operating conditions. No field residual remains at any point in space after the system departs.

PDP-003

Zero-Residual Environmental Signature

Upon de-energization of the coil array — whether through commanded shutdown, coil rotation cycling, or system power loss — the magnetic field at all points in space reduces to zero within a timeframe governed by the speed of electromagnetic propagation (effectively instantaneous at operational scales). The system produces no persistent magnetic signature, no cumulative environmental field modification, and no residual electromagnetic contamination of the operating environment.

Design Implication The JMPS flight corridor is magnetically clean upon departure. No environmental remediation is required. Repeated flight operations over the same area produce no cumulative magnetic effects.

PDP-004

Coherent Field Translation

During flight operations, the magnetic field envelope translates as a coherent, rigid body with the flight suit. At all operationally relevant velocities (substantially below relativistic thresholds), the field geometry experiences no distortion, elongation, compression, or wake formation due to translational motion. The field interaction geometry between propulsion coils and rear field shaping coils remains invariant with respect to flight velocity and direction.

Design Implication Thrust vectoring response and control authority are velocity-independent. The pilot experiences identical control characteristics at all speeds within the operational flight envelope.

PDP-005

Instantaneous Field Reconfiguration

The magnetic field envelope reconfigures instantaneously upon modification of coil operating parameters — including sub-array rotation, current adjustment, or coil activation and deactivation sequences. No field transition lag, hysteresis, or residual field from prior configurations persists beyond the electromagnetic propagation timeframe. This property enables real-time thrust vectoring and dynamic field shaping without transitional instability.

Design Implication Sub-array thermal rotation (5-coil cycling) produces no perceptible discontinuity in propulsion performance. Field shaping transitions are operationally seamless.
