Abstract
An aircraft capable of hovering, and having a fuselage defining an access opening; driving means for operating a rescue cradle; and a first wall movable between a closed position engaging a first portion of the opening, and a first open position allowing access to the first portion of the opening. The aircraft has a member connected functionally to the first wall and in turn having at least one flat surface; and the member is movable with respect to the wall into a first position, in which the flat surface defines a supporting surface for the cradle when the first wall is in the first open position.
Claims11
An aircraft capable of hovering, and comprising;
- a fuselage defining an access opening;
- driving means for moving a rescue cradle;
- and
- a first wall movable between a closed position engaging a first portion of said opening, and a first partly open position allowing access to said first portion of said opening;
- the aircraft comprising a member connected to said first wall and in turn comprising at least one flat surface, said member being movable with respect to said first wall into a first position in which said flat surface defines a supporting surface for said cradle when said first wall is in said first partly open position;
- said flat surface being substantially horizontal when said member is in said first position and said first wall is in said first partly open position;
- said first wall being connected to said fuselage, at least in rotary manner about a first axis, and rotating about said first axis to move between said closed position and said first partly open position;
- said first wall rotating about said first axis in a given rotation direction to move from said closed position to said first partly open position, and rotating about said first axis in the same rotation direction to move from said first partly open position to a second fully open position;
- said member comprises a first end edge connected functionally to said first wall, and a second end edge opposite said first end edge;
- said first wall comprising a third edge connected functionally to said fuselage at least in rotary manner about said first axis, and a fourth edge opposite said third edge;
- said second end edge and said fourth edge do not interfere with the lowering of said cradle when said member is in said first position and said first wall is in said second fully open position;
- said flat surface being substantially horizontal and defining a tread when said member is in a second position and said first wall is in said second fully open position.
A method of retrieving a rescue cradle into a fuselage of an aircraft capable of hovering, said fuselage comprising an access opening, and a wall which rotates about an axis and in turn comprises a first edge connected to said fuselage, and a second edge opposite said first edge, said method comprising the steps of:
- raising said cradle outside said fuselage;
- moving said wall into a first partly open position allowing access to at least a portion (24) of said opening when said raising step is terminated;
- resting said cradle on a supporting surface defined by a flat substantially horizontal surface, said flat surface being defined by a member fitted to said wall and set to a first position with respect to the wall;
- moving said wall into a second fully open position prior to said raising step;
- said second edge being located at a first distance from a longitudinal plane of said fuselage when said wall is in said first partly open position, and being located at a second distance, smaller than said first distance, when said wall is in said second fully open position;
- said plane being parallel to said axis;
- moving said member into said first position with respect to said wall when said wall is in said second fully open position;
- rotating said first wall about said first axis in a given rotation direction to move from said closed position to said first partly open position;
- and
- rotating said first wall about said first axis in the same rotation direction to move from said first partly open position to a second fully open position;
- wherein said member comprises a first end edge connected functionally to said first wall and a second end edge opposite said first end edge, said first wall comprises a third edge connected functionally to said fuselage at least in rotary manner about said first axis and a fourth edge opposite said third edge, said second end edge and said fourth edge do not interfere with the lowering of said cradle when said member is in said first position and said first wall is in said second fully open position, and wherein said fiat surface is substantially horizontal and defines a tread when said member is in a second position and said first wall is in said second fully open position.
