Problems solved by technology

However, these curtains remain small in size and are only valid for short periods of time, as well as providing only small output
Also, the concealment efficacy is not enough, since the opacity coverage is not uniform
[0007] In general, pyrotechnics provide fumes that do not satisfactorily conceal the ship (size, duration, efficacy) and result in high costs and a not insignificant level of risk in handling

Embodiment Construction

[0044] Throughout the text, the qualifiers "upstream" and "downstream" refer to the relative positions of elements of naval vessels within the standard directions of navigation of those vessels. The front of these ships is upstream and corresponds to the bow, while the rear is downstream and corresponds to the stern of the ship. Furthermore, "horizontal" means parallel to the deck(s) of the ship and "vertical" means perpendicular to the deck(s).

[0045] refer to figure 1 A schematic diagram of a gas turbine type, such as for example a GPU (Ground Power Unit) type engine, modified to be used as a "flue gas turbine" in a concealed device 10 according to the invention. A GPU is a stationary or movable gas turbine used to start the main engine and generate non-propulsion (pneumatic, electrical or hydraulic power) for a vehicle or aircraft.

[0046]The GPU 1 mainly comprises a gas generator 2 and an exhaust pipe 3, the GPU 1 is connected to a fuel container 41 and at least one c...

Abstract

The invention relates to a method for effective concealment that lastingly covers all or the essential portions of vessels and the area around same, as well as the crews thereof. For said purpose, the invention provides for coupling an air flow to an injection of fluid capable of causing the formation of a cloud, followed by positioning said cloud in order to optimise the coverage of the vessel and the area around same to be protected. According to the invention, a concealment apparatus comprises a gas turbine (1) coupled to a duct (11') for discharging a flow of smoke (F3) consisting of a combustion gas charged with droplets of fluid in suspension. According to one embodiment, the duct (11') comprises two arms (11'a, 11'b) which are connected to each side half (103a, 103b) of the hull (103) of the vessel (102). The arms (11'a, 11'b) are symmetrical relative to a vertical plane Pv of symmetry of the ship (102) and, due to the curvature thereof, are generally directed (arrow F4) toward the rear (AR) of the ship (102). Thus, the flow of smoke (F3) is also directed toward the rear (AR) of the ship (102). The invention is useful in particular for all types of naval vessels.

Description

[0001] manual technical field [0002] The present invention relates to a method and a device for concealing a naval vessel such as a ship, yacht or watercraft, and to a naval vessel equipped with at least one such device. [0003] The background of the invention is the protection of naval vessels and their environment, stationary or in motion, by means of cloud concealment of vessels in the radiation perceptible range. The purpose of this concealment is to prevent any aggression or boarding of the ship. [0004] This field concerns the creation of opaque environments, usually formed by particles, such as liquid particles suspended in the air to form clouds, or, for example, solid particles also suspended in the air to produce smoke. [0005] As the ship to be protected moves across the water, the generation of the opaque environment must be able to be consistent with the ship's motion. It is therefore provided to install on board or in a ship a device for generating such an...
