Latest Patents
One of Logan's latest patents is the Helicopter Auxiliary Energy System. This invention allows autorotation in helicopters at low altitudes, even when the helicopter's design may not typically support it. The system utilizes a flywheel to store angular kinetic energy from the main propulsion engine, which can be transferred to the main drive shaft in the event of engine failure. This mechanism ensures a safe landing by maintaining energy supply during critical situations.
Another significant patent is the Landing Gear Energy Distribution and Righting System. This system incorporates hydraulic cylinders in the landing gear of an aircraft, which are interconnected through hydraulic restoring devices. These devices help restore the landing gear to an equilibrium position after disturbances, absorbing impact energy during non-level landings. This innovative approach enhances the aircraft's stability and safety during landing operations.
