Description

A utility model relates to the field of means and methods for sheltering or masking using masking aerosols.

The TPO-50M infantry flamethrowers (Storage Manual for TPO-50M heavy infantry flamethrower and the TPO-50M upgraded heavy infantry flamethrower) are known that are stored in storage. M .: Voenizdat, 1959, 94 pp.). The action of the flamethrower is based on the ejection of the flame mixture by the pressure of the powder gases generated during the combustion of the powder charge, and ignition of the flame mixture stream when it is emitted from the nozzle by the flame of an incendiary star.

It is known to use the TPO-50M heavy infantry flamethrower as a universal aerosol generator.

The closest in technical essence to the claimed device is a universal aerosol generator according to the patent of the Russian Federation for invention No. 2119143, IPC F 41 H 9/06, 1998. It uses a barrel with a barrel of heavy infantry flamethrower TPO-50 M to set aerosol curtains, which equipped with aerosol formulations instead of flammable mixtures. This device allows you to use the standard heavy infantry flamethrowers TPO-50M available for storing aerosol curtains in order to mask their troops. This is achieved by the fact that the barrel with the barrel, which is included in the TPO-50M kit, is equipped with a self-smoking smoke mixture (30% solution of sulfuric anhydride in chlorosulfonic acid - mixture C-4) in an amount of 21 liters. Then the powder chamber is assembled. To do this, it is equipped with a powder charge, an incendiary star and a pyro cartridge PP-9 for the production of an electric starting method. Assembly and installation of the powder chamber is carried out in accordance with the operations set forth in the "Guide to

TPO-50M. "

When bringing a universal aerosol generator into action, a powder charge in 0.25 ... 0.32 seconds throws an aerosol-forming composition through the generator barrel. Due to the dispersion of the aerosol-forming composition by powder gases under high pressure, a continuous cloud is formed during 0.3 ... 0.5 seconds.

The disadvantage of the design of this aerosol generator is the pulsed and disposable nature of the action and the short time of its operation.

The objective of the utility model is to increase the efficiency of aerosol curtains in order to mask their troops.

The technical result that can be obtained using the utility model is to increase the operating time of the aerosol generator and its repeated use.

The task is achieved by the fact that a second generator is introduced, combined with the first generator by means of a pipeline with an intermediate cavity, into which a common aerosol barrel is placed so that its lateral inlet openings are recessed into the intermediate cavity, while two non-return valves are installed in the pipeline, and between them - a tee.

The essence of the utility model is illustrated in the drawing.

A universal aerosol generator consists of the following main parts: a cylinder 1 with an aerosol mixture 2, a barrel 3 and an intermediate cavity 4. The aerosol mixture 2 is supplied using a supply system, which includes a powder chamber 5, consisting of a body with a gas nozzle 6, a powder charge 7, incendiary sprocket 8 and igniter 9, as well as the piston - shutter 10.

The powder chamber 5 is used to place an igniter device (incendiary sprocket 8), a powder charge 7, a grate, a gas nozzle 6 and other parts providing a shot. She is mounted

on the front bottom of the cylinder 1. On the cover of the powder chamber 5 there are holes for the flare tube of the capsule contact (with the electric method of driving the generator into action) and for a mechanical fuse. The flare tube serves to exit the flame of an incendiary sprocket, setting fire to a jet of a generator.

In case of excess of pressure inside the cylinder 1 above the limit value (120 atm), a safety valve 11 is provided. For filling the cylinder 1 with an aerosol mixture 2, a filling valve 12 is installed.

Universal aerosol generator operates as follows. The aerosol generator can be operated in various ways. With the mechanical method of driving the generator into action, the mechanical fuse ignites the RSKS-3 cartridge, and with the electric method, the current from the BAS-80 battery or from the blasting machine ignites the pyro cartridge 9 of the PP-9 type.

In this case, the flame of the igniting sprocket 8 through the asterisk’s cup ignites the powder charge 7. The powder gases generated by the combustion of the charge in the powder chamber through the outlet nozzle 6 of the launch chamber 5 enter the gas region of the cylinder 1 and provide pressure in it. This pressure is transmitted through a piston - sealer 10, which delimits the liquid region and the gas region in the cylinder 1 to the aerosol mixture 2. The piston - sealer 10 evenly distributes the pressure of the powder gases to the surface of the aerosol mixture 2. Under the influence of this pressure, mixture 2 is squeezed into the aerosol barrel 3 through the intermediate cavity 4 and through holes 15 made on the side surface of the barrel 3.

In this case, the check valve of this cylinder (working) opens, and the other cylinder (refueling) closes. Aerosol mixture 2 from the working cylinder 1 through the check valve 13 and the tee 14 under pressure is supplied to the barrel 3. When the pressure reaches above the working value, the barrel membrane 3

cut off and the jet of mixture 2 is thrown towards the target. When flying out of the barrel, it is ignited by the flame of an incendiary star 8.

For the further installation of the aerosol curtain after the complete production of the aerosol mixture 2 from the working balloon 1, it is necessary to give a command to activate the squib 9 of the second balloon 1. In this case, the new working balloon will work similarly to the above. The aerosol mixture 2 through the open check valve 13 of the new working cylinder 1 through the adapter 14 enters the internal cavity of the aerosol barrel 3.

The table below shows the positions of the filling 12 and 13 check valves under various operating conditions of the device.

Parts Name The state of the fitting (valve) + is open; - closed Filling the first cylinder The supply of the mixture from the first cylinder First cylinder filling nipple + - First cylinder check valve - + Refill fitting for the second cylinder - - Second cylinder check valve - -

If necessary, refueling a non-working cylinder can be carried out both during operation of the universal aerosol generator and autonomously. For this, a tee and fittings on the cylinders are provided.

In the initial state, the developed design can be both in the assembled state (fixed on the carriage, consisting of a frame with centurions, an arm with clamps for installing the barrel, etc.), and in a disassembled state. This allows you to transport it on any available vehicle. In the latter case, the universal aerosol generator is assembled at a position immediately before its use.

The advantages of the proposed universal aerosol generator are:

- increased time for placing aerosol curtains in order to camouflage their troops by simultaneously refueling one of the cylinders with an aerosol mixture and using another cylinder for direct curtain installation;

- the possibility of using a universal aerosol generator both as a flamethrower and as an aerosol curtain due to the fact that both the flammable mixture and the aerosol forming composition can be refilled;

- the possibility of reuse of the developed device due to reloading of cylinders;

- the ability to use the standard heavy infantry flamethrowers TPO-50M available for storage;

- the possibility of transporting a universal aerosol generator on any available vehicle and assembling it directly to the position.

Thus, the proposed universal aerosol generator can improve the efficiency of aerosol curtains, is universal, because It can be used both as a flamethrower and as a generator, and also has improved operational characteristics.
