Definitions

  • Landing wheels of air crafts are always dead and do not have any means of driving power. They are meant just for rolling over. They have only a breaking system to decelerate and stop the air craft on ground.
  • This invention suggests to make all landing wheels (main wheels and nose wheels) rotate at a correctly synchronized ground speed, prior to touching the ground to minimize the landing jerk, by some means of power. So that it will not skid on the runway at the touching point when landing.
  • a road speed sensor located on landing gear posts or underside of fuselage, it senses the landing speed of the air craft, at last moment but well before touching and adjust the power supply to the motors to synchronize the ground speed. This will help for a smooth touch down even at a higher landing speed because there are no rubbing wheels, everything is well synchronized.
  • Both types of motors can have in form of 'Hub Motors'. Each wheel can have its own motor for simplicity. There should be a suitable arrangement to find and manipulate the space inside the hub in conjunction with disc-break system.
  • all (Jet) engines are having enough excess compressed air and electric power, as they have no big demand at this moment.
  • a very thin (Eg: about 2.5cm thick) compressed air or electric motor to fit inside the wheel hub.
  • These motors need to have small power output as wheels are free to rotate and there is no load at all. The process can be started from the moment, once the landing gears are dropped down from the cages.
  • the wheels may be fitted with propeller blades which start rotating as soon as they come out. This method is self synchronizing.

Abstract

La présente invention concerne un système d'atterrissage pour véhicules aériens leur permettant d'effectuer des atterrissages sûrs et en douceur. Lorsqu'un véhicule aérien atterrit sur le sol, les roues sont déployées mais elles ne tournent pas jusqu'à ce qu'elles touchent le sol. Lorsque les roues immobiles touchent le sol, du fait de l'énorme quantité de mouvement du véhicule et de l'inertie des roues, les roues abrasent fortement le sol, ce qui n'est pas souhaitable et peut même provoquer des accidents. La présente invention porte sur un mécanisme qui permet de faire tourner les roues avant qu'elles ne touchent le sol, ce qui permet d'éviter l'abrasion intense provoquée par l'énorme quantité de mouvement.
