Latest Patents

One of Leoni's latest patents is the "Landing gear in-flight vibration dampener." This invention allows helicopter landing gears to be suspended by a tuning spring in the airframe, providing limited relative movement between the landing gear masses and the airframe. As the aircraft vibrates due to forces at the rotor head, the landing gear masses react oppositely, generating balancing forces that help stabilize the rotor excitations. Another significant patent is the "Replaceable freewheel unit for helicopters." This invention features a compact arrangement of the gear train elements in the angle gear box for a helicopter main rotor drive. It includes a power input shaft and a power output shaft, with a freewheel unit housed in an axial chamber that can be easily removed without disturbing the gear train's critical relationships.
