Blast-nozzle Cleaners Patents (Class 291/12)
  • Patent number: 4834320
    Abstract: A method and system for reducing stopping distance for an aircraft on a wet runway, which includes blowing away water on a wet landing surface in front of the aircraft tires so that the tires contact a relatively dry surface and simultaneously blowing air on the tires to remove water that may have collected on them. The system includes ducting from the aircraft engine to the landing gear to receive high pressure air bled from the aircraft engine and nozzles connected to the ducting for exhausting high pressure air to the runway in front of the wheels and to the rear portion of the tires. A system of valves in the ducting can be actuated by switches in the cockpit to bleed high pressure air from the engine to the ducting and nozzles during landing of the aircraft.
