ELEMENTS FOR INDUCING ROTATIONAL SPEED OF WHEELS OF THE UNDERCARRIAGE OF AEROPLANES

摘要

The invention relates to elements for inducing rotational speed in the wheels of the undercarriage of aeroplanes. These elements comprise a number of protrusions in the lateral bands of the tyres of said wheels. A concave face with high-resistance to the front wind and another convex face with low resistance are provided. By positioning same in the appropriate position, they generate a pair of forces in the wheel which provides a rotational speed during the initial nearing to the ground, thereby permitting the relative speed between the contact zone of the wheel and the ground to be similar, and the skidding of said wheels to be substantially reduced. The geometrical shapes of the protrusions can be a half-moon, an arrowhead, cup-shaped or strip-shaped.
