4,862/ 65 US. Cl. 29464 Int. Cl. B253 3/00; B66d 1/30 13 Claims ABSTRACT OF THE DISCLOSURE The present invention relates to an engine handling method and apparatus.
According to the present invention, a method of installing an engine in a housing comprises securing curved guide means to the housing to extend downwardly therefrom, engaging at least one guide-engaging element on the engine with said guide means, hoisting the engine into the housing in a position inclined at an angle to the vertical, the engine being guided by said guide means, securing the engine within the housing in said inclined position; and finally removing the guide means from the housing.
The method preferably includes mounting hoisting means on the housing and attaching the hoisting means to a hoist-engaging member secured to the engine, said hoisting means and hoist-engaging member being removed after the engine has been secured within the housing.
The method is particularly applicable where the engine is a gas turbine jet lift engine and the housing has open upper and lower ends, the hoisting means being mounted on the upper end of the housing and the hoist-engaging member being secured to the air intake end of the engine so that the hoisting means hoists the engine through the open lower end of the housing into an installed position in which the intake end of the engine is disposed adjacent the upper, and the exhaust end of the engine adjacent the lower, end of the housing.
The guide means may guide the engine from a position beneath the housing in which the axis of the engine is substantially vertical to an installed position within the housing in which the axis of the engine is inclined to the vertical.
Thus where the housing is inclined to the vertical the guide means may comprise a curved rail extending downwardly from the side of the housing which is spaced further from the ground, the rail being secured to the interior of the housing. The hoisting means are then preferably arranged to hoist from a point above the open upper end of the housing and displaced from the axis of the housing towards the said side of the housing to which the rail is secured.
"ice
The invention also comprises engine handling apparatus for carrying out the method set forth above, said apparatus comprising curved guide means adapted to be detachably secured to an engine housing and to extend downwardly therefrom, hoisting means mounted on the housing adapted to engage the engine and at least one guide-engaging element on the engine for engaging said guide means to guide the engine into the housing at an angle inclined to the vertical as it is hoisted by the hoisting means, a hoist-engaging member adapted to be detachably secured to the engine, said hoist-engaging member including a movable connection element, and said hoisting means including including a flexible hoisting element for attachment to said connection element, said connection element having limited freedom of movement in a substantially horizontal plane so that during operation of the apparatus the point of application of the housing force to the engine changes to accommodate changes in orientation of the engine.
Preferably the or each guide-engaging element is adapted to be detachably secured to the engine.
The invention will be described, by way of example only, with reference to the accompanying drawings, in which FIGURES 1, 2 and 3 show stages in the installation of a gas turbine jet lift engine in an aircraft pod, FIGURE 3 incorporating a modification of the apparatus shown in FIGURES 1 and 2.
Referring first to FIGURE 1, there is shown a gas turbine jet lift engine 10 which has been transported by means of a trolley 11 to a position beneath an open lower end 12 of a pod 13 in which the engine is to be installed. The engine 10 was initially disposed on trolley 11 with its axis 14 horizontal (broken lines) and has been swung in a cradle 15 about a pivot 16 provided on the trolley 11 to the position illustrated in FIGURE 1 in which the axis 14 is vertical. The engine 10 is formed with a number of blind sockets 17 around the internal surface of its intake duct 18 and spigots 19 provided on a sling 20 are received in the sockets 17 to attach the sling 20 to the intake end of the engine 10. A suitable sling 20 is described in US. Patent No. 3,352,592 issued to Rodgers. The sling 20 has an arcuate rail 21 on its upper side on which a ring 22 is slidably retained. A hand-operated hoist 23 is adapted to be mounted by means of a tripod 24 on the upper (intake) surface of the pod 13, enabling a hoisting force to be applied to the ring 22 and thence to the engine 10 through a hook 26 provided at one end of a cable 27 or other flexible hoisting element which forms part of hoist 23.
In this example the axis 13 of the pod 13 is inclined to the vertical, and it is necessary to guide the engine 10 as it is hoisted into the pod 13 so that the axis 14 of the engine 10 coincides with the axis 13' of the pod when the engine is finally installed in the latter.
On the side of the engine 10 which will be spaced furthest from the ground when it is installed in pod 13 there is secured a detachable support 28 carrying a set of rollers 29. The support 28 is secured to a flange 30 of the engine 10 by a toggle-clamp 31 (shown diagrammatically) and to a flange 32 of the engine 10 by a peg 33 received in an aperture 34 in flange 32.
A guide rail 35, which may comprise either a single section or a number of sections bolted together in end-to-end relationship as at 36, is secured to the side of the pod 13 which is spaced furthest from the ground. The rail 35 is secured to the pod 13 by links 37 which are attached to lugs 38 provided on the internal surface of the pod 13 by removable pegs 39 received in apertures in lugs 38. The guide rail 35 extends downwardly from the pod 13, and the rollers 29 are adapted to engage the rail 35 and thus stabilise the engine horizontally while it is being hoisted into the pod 13.
When the hoist 23 is operated, the engine 10 is hoisted into the pod 13 through the open lower end 12 thereof, passing successively through the stages shown in FIG- URES 2 and 3.
Since, in this example, the tilt of axis 14 changes as the engine is raised towards the pod 13, the line of action of the lifting force applied to the engine 10 by the hoist 23 varies accordingly, so that said line of action at all times passes through the centre of gravity 40 of the engine 10. To enable the cable 27 to take up a position along this line while progressively accommodating the changing attitude of the engine 10 as the latter is hoisted, the rail 21 is arcuate in shape, the centre of the arcuate rail 21 being a point (not indicated) on the axis 14 which is at or above the centre of gravity 40, the ring 22 sliding on the rail 21 to permit the line of action of the hoisting cable 27 to vary appropriately. Preferably, the ring 22 and rail 21 are formed of low friction material at least on their inter-engaging surfaces or the ring 22 may be replaced by suitable rollers (not shown) and the rail 21 adapted for these rollers to roll thereon.
When the engine 10 has reached the installed position shown in FIGURE 3, it is secured in the pod 13 by trunnions (not shown) or other suitable means. The tripod 24 and hoist 23 are then removed, the hook 26 being detached from ring 22. The spigots 19 are released from the sockets 17 so that the sling 20 can be detached from the engine 10. The pegs 39 are also removed, thus freeing the guide rail 35, and the toggle-clamp 31 and peg 33 released from the respective engine flanges 30, 32 to free the rollers 29 and their support 28, leaving the engine 10 supported in the pod 13 by said trunnions or other suitable means.
To remove the engine 10 from the pod 13, the reverse procedure to the above is followed, in the sequence of FIGURES 3, 2 and 1. It is to be noted that no specialized tools are necessary in using the equipment according to the invention, nor have the engine 10 or pod 13 any additional fixtures which might increase the weight thereof.
In FIGURE 3, a modified arrangement for securing the guide rail 35 to the lugs 38 of pod 13 is shown diagrammatically. The rail 35 is supported by pivoted links 41 which are connected by removable pegs 39 to the lugs 38. A screw jack 42 or like device is attached to one or both of the links 41 to enable a limited adjustment of the position of the engine 10 within pod 13 to be made to compensate for misalignment of the trunnions or other means on the pod 13 with respect to the engine 10 when the latter is installed in the pod 13.
In a modification (not shown) of the embodiments illustrated, the rail 21 of hoist 23 may be replaced by two intersecting rails and the ring 22 by sliding or rolling elements which co-operate with one of the rails. The sliding or rolling elements would be arranged in use to cooperate with whichever of the rails is selected to coincide as nearly as possible with the line of greatest slope of the axis 14 of the engine 10 when the latter is installed in the pod 13.
