Abstract

FIELD: military engineering. SUBSTANCE: system has axle-pipe 2 secured to a vehicle. Hollow shield 3, made up as bulldozer cutter, rotates about the axle-pipe. The face ends of axle-pipe 3 are provided with exhaust nozzle 4 and shut-off valve 5. Exhaust gas is fed from the engine to axle-pipe 2 through pipe 6 wherein fuel 7 is injected. Axle-pipe 2 has rows of perforation openings 8. Hollow shield is additionally provided with protective sheets 9 and has port 10 for supplying cooling air. Depending on position of cutter of bulldozer 2 and composition supplying to the stream of exhaust gases in pipe 6, the system can provide heating soil and operate as a flame thrower, protective screen and jack for lifting the tail part of a vehicle. EFFECT: expanded functional capabilities. 5 cl, 3 dwg

Description

Изобретение относится к системам отвода выхлопных газов двигателей бронированных транспортных средств. The invention relates to exhaust systems for engines of armored vehicles.

Известны конструкции транспортных средств, у которых системы отвода выхлопных газов двигателей дополнительно выполняют, например, функции дымообразования путем впрыска распыленного дизельного топлива в поток отработавших газов двигателя с целью маскировки. Vehicle designs are known in which engine exhaust systems additionally perform, for example, smoke generation functions by injecting atomized diesel fuel into an engine exhaust stream to mask.

Недостатком указанной конструкции является неполная реализация заложенных в нее возможностей, т.е. возможность использования системы для создания других видов защиты (локационной и инфракрасной защиты). The disadvantage of this design is the incomplete implementation of the capabilities embedded in it, i.e. the ability to use the system to create other types of protection (location and infrared protection).

Задачей изобретения является расширение функциональных возможностей обеспечения защиты. The objective of the invention is to expand the functionality of the protection.

Указанная задача решается тем, что в кормовой части транспортного средства по всей ширине его установлен полый экран, на внешней кромке которого выполнены отверстия для выброса газа. Система снабжена перфорированной осью трубой, к которой подведены отводящие трубы двигателя и на которой подвижно закреплен экран, а ряды отверстий перфорации оси-трубы расположены с возможностью их перекрытия в определенном положении экрана. Торцы оси-трубы снабжены выхлопным соплом и запорным клапаном. Полый экран выполнен в виде ножа бульдозера, а отверстия для выброса газа расположены между зубьями ножа бульдозера. This problem is solved by the fact that in the aft part of the vehicle, a hollow screen is installed over its entire width, on the outer edge of which holes are made for gas emission. The system is equipped with a perforated axis of the pipe, to which the engine outlet pipes are connected and on which the screen is movably fixed, and the rows of holes of the axis-pipe perforation are located so that they can overlap in a certain position of the screen. The ends of the axis of the pipe are equipped with an exhaust nozzle and a shutoff valve. The hollow screen is made in the form of a knife of a bulldozer, and openings for the discharge of gas are located between the teeth of the knife of the bulldozer.

На фиг. 1 изображена конструкция, установленная в кормовой части транспортного средства; на фиг. 2 узел I на фиг. 1; на фиг. 3 вид по стрелке А на фиг. 1. In FIG. 1 shows a structure mounted in the aft of a vehicle; in FIG. 2 node I in FIG. 1; in FIG. 3 is a view along arrow A in FIG. 1.

Система содержит закрепленную на транспортном средстве 1 ось-трубу 2, вокруг которой вращается полый экран 3, выполненный в виде ножа бульдозера. Торцы оси-трубы 2 снабжены выхлопным соплом 4 запорным клапаном 5. Подвод выхлопным газов от двигателя к оси-трубе 2 осуществлен трубой 6, в которую осуществляется впрыск топлива 7. Ось-труба 2 перфорирована рядами отверстий 8. Полый экран 3 дополнительно снабжен защитными листами 9 и имеет окна 10 для подвода охлаждающего воздуха. The system comprises a pipe axis 2 fixed to the vehicle 1, around which a hollow screen 3, made in the form of a bulldozer blade, rotates. The ends of the axis of the pipe 2 are equipped with an exhaust nozzle 4 shutoff valve 5. The exhaust gas from the engine to the axis of the pipe 2 is carried out by a pipe 6, into which fuel is injected 7. The axis of the pipe 2 is perforated with rows of holes 8. The hollow screen 3 is additionally equipped with protective sheets 9 and has windows 10 for supplying cooling air.

Система работает следующим образом. The system operates as follows.

В зависимости от положения ножа бульдозера 2 и подачи различных компонентов в струю выхлопных газов в трубу 6 система может обеспечивать разогрев грунта, работать в качестве огнемета, создавать дымовую завесу или защитное облако от тепловых средств самонаведения, выполнять функции защитного экрана или грузовой платформы, а также подъемника кормовой части машины. Depending on the position of the knife of the bulldozer 2 and the supply of various components to the exhaust gas stream into the pipe 6, the system can provide heating of the soil, work as a flamethrower, create a smoke screen or a protective cloud from thermal homing equipment, perform the functions of a protective screen or cargo platform, and lift aft of the machine.
