The drawer frame comprises the two side pieces (2, 3), the front piece (1) and the back piece (4), and is joined by dovetail joints comprising dovetail protrusions and dovetail grooves.

In a titanium hub, dovetail shaped slots are used for accommodating dovetail shaped roots of fan blades.

Each channel (515) has a similar, half-dovetail profile (560), and a frame extending member (520) is associated with each channel.

The first locking piece touches and supports the dovetail groove (4).

A neck supports the airfoil and interconnects to a dovetail by opposing radii.

The dovetail includes a bearing surface tangent to one of the radii at a tangent point.

At least the inwardly facing walls of the dovetail shaped slots are coated with a dry film lubricant.

The protrusion (7) may be rectangular or dovetailed, or be provided with an upper end extending inwardly.

A tapered router bit (102) is guided along the inner edge of the side projections to create a dovetail slot.

The inwardly directed pressure faces of the dovetail shaped root of the fan blades are covered with polymeric wear mitigation pads.

According to the invention, the mounting link (3) is inserted into a link bearing (13) of the socket base body (1), which link bearing has a dovetail-shaped groove (15).

The upper and/or the lower side of side bars (3) and end sections (2) contain dovetail-shaped through grooves (13) for receiving fasteners (22) and a ticking (23).

The cover (9) may have one or more edges of a dovetail construction (11) so that cover sections (9) of modules may be connected together to cover a desired walkway area, in which case electrical connections (2) are provided between individual modules.

Dovetail mortises (1) are set on the three edges of the module, and a longitudinal through hole (2) or a lateral through hole (3) for installation is set in the middle of the module.
