Latest Patents
One of Radkey's notable inventions is a solar rechargeable aircraft. This aircraft is designed to be inexpensive to produce, steerable, and capable of remaining airborne almost indefinitely. The preferred design features a span-loaded flying wing without a fuselage or rudder. It operates at relatively slow speeds and boasts a two-hundred-foot wingspan, which is equipped with photovoltaic cells on most of the wing's top surface. The aircraft utilizes differential thrust from its eight propellers for turning. Each section of the wing is equipped with engines and photovoltaic arrays, allowing them to produce lift independently. The aircraft can reach a top speed of about ninety miles per hour and maintain altitudes of up to sixty-five thousand feet. Additionally, regenerative fuel cells in the wing store excess electricity for nighttime use, enabling indefinite elevation.
Another significant patent involves a leading-edge inlet for a ram-air pressurized airfoil. This design features an air scoop opening at the leading edge of a flexible, ram-air inflated airfoil canopy. The scoop is framed by curved lip sections that prevent airflow separation and reduce drag. A baffling curtain extends across the air scoop opening, enhancing the efficiency of the airfoil.
