Abstract

A runway, oil rig landing platform, or landing strip on an aircraft carrier, is provided with means for generating an electromagnetic field. An aircraft or helicopter undercarriage is provided with a metallic fixture, such as a ski or plate 5, which may be lowered or raised by means of a hydraulic cylinder 3, the fixture interacting with the electromagnetic field on landing of the aircraft/helicopter to brake the aircraft's motion and hold the aircraft/helicopter down.

Description

Landing platform for helicopters and helicopters without wheels.

The helicopter must be fitted with its own metallic fitting set in the bottom fixture in order for it to be attracted to the electromagnetic field of the platform.

The electromagnetic field has to be spaced out across the platform in small strips. When the helicopter comes down to land it has to be activated to hold the helicopter down and, if necessary, secure with brackets.

Fig. 3 The platform has to have the electromagnetic field embedded flat with the top and must be activated before a helicopter lands.

Landing gear and platform for helicopter and planes Fig. 1

An electromagnetic platform for safe landing on oil rigs, flat roofed houses, warships, aircraft carriers and airfields, with the fixture or frame to keep the helicopter on the ground. The fixture must have a metallic fitting to attract it to the electromagnetic field on the platform.

Helicopters with wheels must have fixtures fastened on to the axis or struts which have to have a hydraulically controlled pressure mechanism to enable the pilot to move the fixture up and down. As the tyres compress by touching the platform or landing strip the pilot must adjust, if

necessary, and activate the sliding skis through the hydraulic pressure. They must also be of a metallic material to be attracted to the electromagnetic field on the platform or landing strip on aircraft carrier.

The aircraft can be stopped it there is enough power in the electromagnet and so preventing it from overshooting the aircraft carrier or airfieìd, The electromagnetic fields must be of various strengths to match the size of the different

helicopters and planes. especially in stormy weather. The hydraulic cylinder must be able to move up and down as well as pivot because planes come down to land at an angle. The helicopter takes off and lands in more of a vertical direction, but there is stiR a pivotal movement necessary.

The pilot has to control the hydraulic brake mechanism as the trailing ski will touch the platform first and give the pilot a warning light This informs the pilot that the skis must go down to brake the aircraft and prevent overshooting the aircraft carrier or the air field The electromagnetic fields must be embedded flat into the platform, runway and deck on aircraft carriers and oil ngs,

Amended claims have been filed as follows CLAIMS 1. An aircraft landing system comprising a landing surface for receiving and supporting a landing aircraft, said surface comprising electromagnetic means embedded therein for generating an electromagnetic field, said aircraft landing system further comprising an aircraft having an undercarriage provided with a plurality of wheels, a plurality of elongate metallic plates movably mounted on said aircraft, a plurality of hydraulic cylinders each connected and arranged so as to be capable of moving a respective one of said plates relative to a respective one of said wheels between a first position, in which said respective one of said wheels projects beneath said respective one of said plates, relative to the aircraft, and a second position, in which said respective one of said plates can contact said landing surface upon landing of said aircraft on said surface, a warning light for the pilot of said aircraft, and means for actuating the warning light as a plate touches said landing surface, said electromagnetic means, being capable of being activated to produce a magnetic field of sufficient strength to attract said elongate metallic plates to said surface whereby to hold said aircraft on said surface.
