Introduction

Charles L Johnson is a notable inventor based in Madison, AL (US), recognized for his contributions to space technology. He holds three patents that showcase his innovative approach to propulsion systems for spacecraft. His work has significant implications for the future of space exploration.

Latest Patents

One of Johnson's latest patents is the Electrodynamic Tether, which is a tether system designed to provide thrust or power subsystems of an artificial satellite in low Earth orbit. This tether consists of three main sections: an insulated section connected to the satellite, a conducting section that draws in and releases electrons from space plasma, and a non-conducting section that maintains tension among the other sections. An oxygen-resistant coating is applied to the conducting section's bare wire and the insulated wires to prevent breakdown during operations in space plasma. Additionally, the insulated and bare wire sections are surrounded by a high tensile flexible polymer core to protect against debris.

Another significant patent is the Combination Solar Sail and Electrodynamic Tether Propulsion System. This innovative propulsion system integrates a solar sail system with an electrodynamic tether system. The solar sail generates propulsion using solar photons, while the electrodynamic tether system facilitates orbital maneuvers and power generation using a planet's magnetic field.
