Abstract
A hovercraft skirt segment has additional wear material in the form of small mesh chain mail 5 added to its front panel 2 to improve wear and tear resistance whilst maintaining flexibility. Anti-tear strips (6, 7, figure 2) may also be bonded to the inside of the front panel, and a heat tracing element may be attached to the chain mail to prevent freezing to the ground in very cold conditions.
Description
Re-enforced Hovercraft skirt segment This invention relates to a
re-enforced Hovercraft skirt segment (RHSS) that is a standard finger segment as used on Hovercraft and Hoverbarges to contain the air or gas cushion and particularly suited to operations that include transport over broken ice, tree stumps and rocks that would normally tear the rubber skirt material.
BACKGROUND TO THE INVENTION
Hovercraft and Hoverbarges are used for putting men and equipment ashore and used by both the Milftary and civil engineers. Mostly they operate in environmentally friendly areas but more wolic is now taking place in areas that will cause greater wear on the skirt segments that contain the air or gas cushion. Sharp ice, rocks and sawn off trees can tear the rubber material the skirt segments are made from.
This invention uses additional wear layers to increase the skirt life whilst allowing ft to remain flexible. The flexible seal could be constructed by a skirt bounded around the periphery of the hull base to contain the cushion and formed with a plurality of segments used in hovercraft skirt systems.
SUMMARY OF INVENTION
The object of the present invention is to provide a superior wear resistant panel to increase the life of the hovemraft and Hoverbarge skirt systems.
Another object of the invention is that this panel can be used to transfer low levels of heat to the skirt system so that it does not freeze to the ground.
BRIEF DESCRPITION OF SEVERAL VIEWS OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION
The invention will be described by way of example and with reference to the accompanying drawings in which:-Fig 1 presents an isometric view of a standard Hoveitraft or Hoverbarge skirt segment with side waIls (1) wrapped back to form a triangle with the front panel (2) and top edge (3) and back edge (4). Small link chain mail (5) is fitted to cover the front panel (2) and is pulled around the corners 2/2 onto the sidewalls (1)to give wear protection. It is the chain mail which will take the initial impact and wear from sharp ice and rocks. The chain mail links also allow flexibility.
Fig 2 presents a view of the inside of the skirt segment laid out on its face. Running across the side walls and the front panel are two anti tear re-enforcing stnps (6) & (7) which are hot bonded to the main segment. These will stop tears running up from the back edge (4) and dividing the skirt segment into two sections.
Fig 3 presents a view of the outside of the skirt segment laid out on its back Running across part of the side walls (1) and all the front panel (2) is a panel of small mesh chain mail (5) secured to the outer face of the skirt segment to reduce tearing and wear.
Fig 4 presents a view of the inside of the skirt segment laid out on its face. Running across the side walls and the front panel are two anti tear re-enforcing strips (6) & (7) which are hot bonded to the main segment. In addition the chain mail (5) is return around onto the lower inside edge of the front panel (2) to give extra protection to the lower outer wearing edge (4) and help reduce tears starting at the bottom of the front panel (2).
Fig 5 presents a view of a section of the skirt segment as viewed from the inside with one side wall (1) removed for clarity. This view shows the anti wear strips (6) & (7) and the chain mail (5) returned around the lower section of the back edge (4) of the skirt segment.
Claims (4)
1. An improved standard Hovercraft or Hoverbarge skirt segment that has additional wear material in the form of small mesh chain mail fitted to the front outside face of the skirt segment so that it has flexibility and improved wear and tear resistance.
2. The improved skirt segment of claim I where additional anti tear strips are hot bonded across the inside front panel to reduce tearing from the bottom edge of the skirt.
3. The improved skirt segment of claim 1 where the small chain mail mesh is brought around the back edges lower section, to reduce tearing and wear.
4. The improved segment of claim I where a heat tracing element can be attached to the chain mail fitted to the skirt segment so as to stop freezing to the ground in artic conditions.
