Abstract

A protective cover for an aircraft engine comprises a lower portion mountable to a corresponding lower portion of an opening of the engine, and an upper portion articulated to the lower portion. The upper portion is deployable from a collapsed position to a deployed position in which the upper portion extends upwardly from the lower portion. A handling tool may be used to operate the panel from a remote location on the ground.

First claim

The invention claimed is:

1. A kit for protectively covering an opening of an aircraft engine, the kit comprising:
a cover including:
a base having an arcuate lower surface configured to mate with an inner surface of a lip of one of an intake and exhaust portion of an engine casing of the aircraft engine; and
a panel movably connected to the base between a first position where the panel is stowed and a second position where the panel is deployed to close off the opening of the engine, the panel having at least one handling feature accessible while the panel is in said first and second positions; and

a handling tool for engaging the panel from a location remote from the aircraft engine, the handling tool having a handle portion, a telescopic pole and an operative end at a distal end of the telescopic pole opposite to the handle portion, the operative end cooperating with the at least one handling feature of the panel for moving the panel between the first position and the second position from a location remote from the aircraft engine when the cover is installed on the aircraft engine.

2. The kit of claim 1 , wherein a retainer feature is provided between the base and the panel for automatically preventing the panel from moving relative to the base after the panel has reached the second position.

3. The kit of claim 1 , wherein the panel has a diameter larger than a diameter of the base.

4. The kit of claim 1 , wherein the panel includes two semicircular portions hingedly connected to each other.

5. The kit of claim 1 , further comprising a plurality of pivotable flaps distributed about a periphery of the panel, the flaps being configured to cover an outer surface of a lip of the engine.

6. The kit of claim 1 , wherein a front surface of the base includes at least one attachment cooperating with at least one attachment of the panel when the panel is in the second position for releasably retaining the panel in the second position.

7. The kit of claim 1 , wherein the base is a first portion of a disk, the panel is a second portion of the disk the panel being rotatable between the first position and the second position, the panel being rotatable relative to the base about a central axis of the disk formed by the first and second portions.

8. The kit of claim 7 , wherein the first portion is a half disk, and the second portion is a complementary half disk.

9. The kit of claim 1 , wherein the base has an arcuate runner defined therein, the panel including a first half disk slidably received in the runner, the cover including a second half disk fixedly connected to the base; wherein in the first position, the half disk is engaged in the runner in overlapping relationship with the second half disk; and wherein in the second position, the first half disk is disengaged from the runner and the first and second half disks cooperate to form a full disk.

10. The kit of claim 1 , wherein the panel includes a plurality of portions hingedly connected to each other, when the panel is in the second position, the plurality of portions self-lock.

11. The kit of claim 1 , further including a storage box, the storage box receiving the cover and the handling tool, wherein the storage box is usable as a step for an operator to climb onto.
