Abstract

To rotate an aircraft landing wheel prior to touch-down, an impeller fitted to the wheel is turned by the airstream. The impeller comprises three spaced-apart coaxial discs, with two semi-circular blades between one outer disc and the middle disc, and two between the other outer disc and the middle disc, one pair of blades being circumferentially offset 90 DEG relative to the other pair. <IMAGE>

Description

SPECIFICATION Wheel Impeller When the aircraft lands, you see smoke coming out of the tyres, then you hear the screaming of the tyres, and then the smelling of burning rubber, that happens because the wheel is not turning, that means a great shock on the undercarriage and wear and tear of the tyres.
If a wheel impeller is fitted on each wheel, the shock will be minimised and the wear and tear of the tyres eliminated because when the aircraft prepares the undercarriage for landing, the rushing air starts turning the wheels to prepare them for landing.
This drawing is made to the specifications of a wheel with a rim of 60cm and it should be made of light strong metal 2mm thick.
Claim
The wheel impeller which I developed is a hub with three plates separated by two sets of blades two on each plate and one on the middle. The sets of blades are fitted at 900 to each other, they are half round and they are in a position to catch the wind and throw it to each other, and by that, they make the wheel turning and so the Aircraft will have a smooth and safe landing.
The size of the impeller should be as big as the diameter of the rim, I have tried this impeller on the stepny of my car which I fitted on the side were I use to fix the jack and it picked the revolutions which they matched the speed of the car.
