Definitions

  • the present invention relates to an arrangement for arresting landing aeroplanes by means of a wire, net or the like connected to brakes disposed on either side of a landing runway.
  • the present invention is mainly characterized in that the brakes for both sides of the arresting wire are interconnected by an endless wire, chain, cable or similar flexible element for synchronizing the rotational speeds of the brakes during the arresting operation.
  • a distinct advantage following from the invention resides in the fact that the brakes may be connected on or above the landing runway, whereby the installation will be simple and easy to be made at existing runways, since the runway need not be closed 01f during the period required for making the installation.
  • the synchronizing wire may be one of substantially smaller dimension than the arresting wire and braking wires, since only a portion of the braking load will be transmitted from one brake to the other.
  • Such a small gauge wire can be placed on the runway without any risk. If the hook of the aeroplane which is intended to engage the arresting wire should fail to properly engage it, it will not hook onto the small gauge synchronizing wire disposed beyond it. Even greater safety to prevent this will be attained if the synchronizing wire is flattened and is placed with its flat face directed toward and is lying against the surface of the landing runway.
  • FIG. 1 shows diagrammatically the structure and operation of the improved aeroplane arresting apparatus
  • FIG. 2 is a vertical sectional view of a brake drum having two grooves for respectively receiving the arresting cable and the synchronizing cable;
  • FIG. 3 shows a brake drum having two grooves for a flat arresting cable and a similar synchronizing cable
  • FIG. 4 shows how a synchronizing cable is arranged in a manner to lie fiat against the surface of a'runway
  • FIG. 5 shows how the synchronizing cable is caused to be disposed below the landing surface or runway.
  • the numerals 1 and 2 designate brake drums disposed on either side of a landing runway.
  • Brake wires 3 and 4 are wound around the respective drums 1 and 2, said wires being connected by an arresting or catching Wire 5.
  • the wires 3 and 4 and the connected wire 5 are resistantly let out from the brakes.
  • the brake drums I and 2 are connected by an endless synchronizing wire 6 encircling the drums.
  • the direction of approach of an aeroplane is indicated by the arrow 7.
  • the synchronizing wire 6 is disposed on the runway forwardly of the arresting Wire 5, as seen in the direction of approach of the aeroplane. This is made possible by extending the wire 6 over guide pulleys 8, 9, 10 and II which are located in advance of the brake drums I and 2.
  • Designated at 12 is a pneumatic or hydraulic wiretensioning device which is anchored to the runway and is connected to the guide pulley ill.
  • This tension device has the dual function of first, tensioning the Wire 6 in conjunction with the plane interception, so that upon movement of the wire 6, air or liquid under pressure will in a well-known manner, he applied to the wire tensioner, causing the latter to attract the guide pulley 10, and second, to limit the tension exerted on the wire 6 so that its strength limit will not be exceeded. Owing to the fact that the wire 6 is not initially tensioned, it will normally lie on the surface of the runway, and it thus cannot, especially if it is fiat, get caught by the catching hook of the aeroplane.
  • FIG. 4 shows how the synchronizing cable 6 is arranged to lie flatly against the face of the runway or landing surface.
  • the cable therein shown is a fiat band and it is turned so that its face lies parallel to the face of the landing surface by means of the rollers 13 which are spaced away from the pulleys 8 and 9 so that the fiat band, constituting the cable 6 will be turned
  • the tensioning device 12 is shown as applied to the pulley 9 rather than to the pulley It as in FIG. 10.
  • FIG. 5 is shown the manner in which the synchronizing cable or wire may be located beneath the runway or landing surface.
  • the brake 1 is located above the landing surface as are the pulleys 8 and 9.
  • the cable after leaving the pulleys 8 and 9, passes through apertures 15 in the runway 16 to Patented Nov. 24, 1964 all reach the under side of the landing surface or runway where it is guided by the pulleys 13.
  • the brake drums 1 and 2 are each provided with two grooves indicated respectively at 1'7 and 18.
  • the groove shown at 17 receives the arresting wire 3 and the groove shown at 18 receives the synchronizing cable 63.
  • the drum shown in PEG. 3 shows how a fiat band used in place of the arresting wire 3 is received in groove 1% with the synchronizing band serving as cable 6 received in the groove Eha.
  • An arrangement for arresting landing aeroplanes by means of a Wire or the like constituting an arresting device said wire being connected to brakes disposed on either side of the landing runway, the brakes being connected by an endless cable separate from the arresting wire constituting a flexible element for synchronizing the rotational speeds of both of the brakes during the arresting operation.
  • An arrangement for arresting landing aeroplanes comprising, a pair of spaced-apart brakes having rotative drums, an arresting cable extending between the brakes, pulleys located forwardly of the brakes in the direction of the landing movement of an aeroplane, an endless brake-synchronizing cable separate from the arresting cable extending around the brake drums and engaging With the pulleys, said cable being disposed below the arresting cable, and a tension device operative on the synchronizing cable to tension the same during the aeroplane-arresting operation.
