Barricade of units for protection of a helicopter from high waves

Abstract

The dangers associated with high waves coming over a helicopter low flight deck is well known by many naval personnel. Waves have been known to damage helicopter engines and nearly washed sailors overboard. This barricade of special designed units will solve this problem completely and without a great cost to the Navy.

Description

BACKGROUND OF THE INVENTION

The dangers associated with high waves coming over the flight deck is well known for some classes of ships. A wall of water struck a whirling helicopter and the force caused it to go overboard. Waves have been known to damage helicopter engines and nearly washed sailors overboard. This has become a common hazard on a ship with a flight deck that rides only 13 feet above the waterline.

The dangers of high wave impacts on frigates and destroyers have been reported in many hazard reports over a 30 year period. This invention is designed to eradicate this problem completely and without a great cost to the Navy. These ships will still be able to carry on their duties.

BRIEF SUMMARY OF THE INVENTION

A solid unit comprising a square or rectangular pan shaped body, and made from a durable material with a sufficient thickness. Connected to this unit is means for fastening the unit to an existing unit. Means for fastening can be a hooking method or a tying method. Many solid units around a helicopter low flight deck are needed to make a barricade.

The barricade will stop most or all of the high waves of water, from coming onto a helicopter low flight deck of any ship with this problem. This is even more important at night or in bad weather.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a partial, side view of the stem of a ship.

FIG. 2 is a side view of a solid unit mounted on an existing unit by a hooking method.

FIG. 3 is a side view of a solid unit showing its pan shape and tie cords.

FIG. 4 is a rear view of FIG. 3.

DETAILED DESCRIPTION

Refer to FIG. 1. There are presently existing units 10 with safety nets placed around the stern 20 of some ships 30, but they cannot stop high waves of water. These existing units 10 with safety nets can be raised or lowered 40.

Refer to FIG. 2. A solid unit 50 can be placed on each existing unit 10 by its hooks 50A. Each solid unit 50 can deflect high waves and winds 60. Many solid units 50 around the stern 20 of a ship 30 will form a barricade to high waves and winds 60. The adjacent solid units 50 should be nearly touching each other. If the outer surfaces 70 of the solid units 50 are painted white this would greatly increase the visibility of the flight deck.

Refer to FIG. 3 and FIG. 4. A pan shaped, solid unit 50 can be molded or made from several parts mended together. The solid unit 50 can be made from a metal or a non-metal. The unit 50 should be relatively strong, lightweight and economical. Tie cords 50B are shown in the above figures. The pan should be shallow.

These solid units 50 can be used only by ships in a Battle Group or on special missions where high speed is very important. Other navies of our allies may have the same problem.

Claims

1. A water barricade.

2. A water barricade.

3. A water barricade constructed with geometric units and each said geometric unit having a means for fastening as claimed in claim 1, said means is tie cords.
