Electrostatic Neutralization System
Radar, IR camera, and lidar for detection and tracking of drones. Acquisition automatique de target up to 500m. Sensor fusion for identification and real-time tracking.
Pressurized cylinder at high pressure (8-50 bar). Capacity matched to the targeted drone category. Pneumatic energy converted into an anti-drone impulse.
Fast solenoid valve with rapid opening synchronized with the tracking system. Opening time < 50 ms.
Conical geometry optimized to stabilize flow. Automatic lead calculation based on target speed.
Sharpened edge creates strong shear. Variable diameter matched to target drone size. Optimal ratio: D_orifice / D_chamber ~= 0.3-0.4.
Electrodes at 10-100 kV for ionization and guidance. Enables in-flight steering toward the target.
Toroidal ring electrostatically guided toward the drone. Trajectory adjusted in real time according to tracking data.
Drone on approach locked by the system. Vortex impact causes destabilization, gyroscopic disturbance, loss of control, and neutralization.
Radar, IR camera, and lidar detect and acquire the target.
Tank charged according to detected drone category.
Electrostatic field established for guidance.
Shot synchronized with calculated trajectory.
Toroidal vortex created at the orifice.
Guided vortex steered toward the target by the electric field.
The vortex applies torque to the drone airframe. Gyroscopes saturate and can no longer compensate, causing attitude loss.
The swirling airflow from the vortex unbalances lift on rotor sets. Each propeller receives a different flow, creating a critical imbalance.
The inertial measurement unit receives data outside its operating range. Abrupt acceleration and rotation can saturate onboard sensors.
Erratic motion induced by the vortex disrupts GPS lock. The drone loses positional reference and enters emergency mode.
Protection of public events, concerts, and sports gatherings from surveillance or attack drones.
Defense of military bases, command posts, and sensitive zones against reconnaissance or armed drones.
Protection of power plants, airports, and nuclear facilities against aerial intrusions.
Neutralization of fast drones during final approach. Requires a multi-vortex system and advanced tracking.

When air is expelled abruptly through a circular orifice, a speed difference appears between the jet center (faster) and the edges (slowed by the orifice).
This shear generates rotation: the air rolls on itself and forms a torus. The circulation Gamma around the vortex core is:
The high-voltage electric field partially ionizes the air molecules. The electrostatic force applied to the charged vortex is:
This force enables guidance toward the target, compensating disturbances and adjusting trajectory in real time according to tracking-system data.
A toroidal vortex can self-propel through mutual induction of its vorticity filaments. Its translation speed is:
where R = torus radius, a = core radius.
