Abstract

An aircraft wheel landing speed equaliser, has a baseplate 1 secured to the wheel 2. From the baseplate 1 flanges, vanes or scoops 4 protrude outward past the wheel rim 5, allowing the air passing the tyre 7 to push against the scoops 4 and rotate the wheel at the equivalent speed of the runway passing beneath it. As shown, the baseplate 1 is made up of four sections (one section only illustrated). This is to enable ease of fitting and replacement. Secured by one wheel stud (not shown) through the hole 3. Holes or notches 6 will be cut to accommodate the wheel studs and nuts (not shown) that are not being utilised so that the baseplate 1 will seat flat against the wheel 2. Other arrangements are disclosed. <IMAGE>

Description

LANDING SPEED EQUALISER This invention relates to an aircraft wheel landing speed equaliser The landing gear of an aircraft does not make any provision to rotate the wheels. Therefore, when the tyres come into contact with the the runway there is an audible and visible indication of localised yet severe tyre wear.
Air craft tyres are expensive. A reduction in the wear caused on touchdown will prolong their life.
According to the present invention there is provided a means of rotating the landing wheels of an aircraft by flanges, scoops or vanes, protruding past the wheel rim from a baseplate, that is reasonably secured to the wheel. Allowing air passing the tyre to rotate the wheel at a speed relative to the runway passing beneath it.
Specific embodiments of the invention will now be described by way of examples, with reference to the accompanying drawings.
Drawing 1/3. Shows one section of baseplate fitted with scoops mounted on a wheel.
Drawing 2/3. Shows a vaned dome mounted on a wheel.
Drawing 3/3. Shows a wheel with vanes or flanges that are incorporated into the design of the wheel.
EXAMPLE 1. Referring to drawing Nol/3, (simplified to show only one section fitted).
The landing speed equaliser baseplate 1 is made in sections which are secured to the wheel 2 by means of the existing wheel studs (not shown) through the hole 3. The air scoops 4 protrude past the edge of the wheel rim 5, allowing the air passing the tyre 7 to rotate the wheel at the required speed for landing relative to the runway passing beneath it.
To enable ease of fitting and replacement, only one wheelstud (not shown) through the hole 3 is used to secure the baseplate 1 in position. Further holes or notches 6 will be cut to accommodate the wheelstud nuts (not shown) that are not being used, allowing the baseplate 1 to seat firmly against the wheel 2.
EXAMPLE 2, Referring to drawing No2/3 The landing speed equaliser baseplate 1 in the form of a dome, is secured to the wheel rim 3 by interference fit, clips or similar means (not shown). Around the baseplate 1 are a number of cups, vanes or flanges 2 that protrude past the wheel rim 3 allowing the air passing the tyre 4 to rotate the wheel at the required speed for landing relative to the runway passing beneath it.
EXAMPLE 3. Referring to drawing No3/3 The landing speed equaliser is incorporated into the design of the wheel 1 in the form of raised vanes or flanges 2 which are part of the wheel casting, are welded in place or secured by other means (not shown) They protrude past the wheel rim 3 allowing air passing the tyre 4 to rotate the wheel at the required speed for landing relative to the runway passing beneath it.

Claims (3)

1 An aircraft wheel landing speed equaliser, comprising a baseplate and raised vanes, flanges, scoops or cups that cause the air passing the tyre to rotate the wheel.
2 An aircraft wheel landing speed equaliser, as claimed in claim 1, where means to secure the baseplate to the wheel is provided, or any part of the wheel or fittings utilised for this purpose.
3 An aircraft wheel landing speed equaliser, as claimed in claim 1 and claim 2, wherein raised flanges, vanes or scoops are incorporated into the design of the wheel, hub or rim.
