Definitions

  • the invention is related to a series of novelty which is used in tracked or wheeled military armored vehicles for forming smoke shrouding in order to reach the aims of providing the bottom cover-body connection by the three numbers of segments in the 76 mm smoke grenade launcher chamber, eliminating the need of perforation upon the contactor by opening the contactor connection spline, which provides the electrical transmission in the launcher chamber, to the metal body and minimizing the labor cost and the problem of rounding by producing the mortar body out of metal as one piece.
  • the launcher of the invention is used as an explosion chamber for the smoke bombs that are launched for the shrouding of the armored vehicles.
  • the explosive that is located into the launcher of the invention explodes as a result of the electrical input from the contactor and makes the smoke bomb launched for about 45 meters of range.
  • the interior of the chamber being kept clean is important for the sake of performing ideal launching.
  • the weapon is covered with a rubber cover when not used.
  • bottom cover is uncovered and mortar launcher is cleaned separately after each use.
  • a spring segment is used for the connection of the bottom cover plenary to the body and this enabled ease in use.
  • the spring segments cannot center the channel exactly, it results in breaking problem for the segments very often.
  • Contactors with plastic bodies serve as transmitting electricity to the mortar ammunition and they are exposed to 14 bar pressure during the launch. In order to decrease this pressure, the conductors in the market are perforated on the top, therefore the pressure is decreased and the breaking of the contactor is inhibited; nevertheless, since a loss occurs in the explosion pressure, the launching distance decreases to 45 meters from approximately 54 meters, which would be the normal distance. In addition, powder gas gets into the base plate from these perforations and causes pollution after the launch.
  • 76 mm mortar launcher body that is used in the market is formed by circular welding of two parts of pipe material to each other. This welding results in rounding in the body. In addition, as a result of melting and solidification, alterations occur in the interior structure (embrittlement). These may cause undesired problems during the production and the use of the product. Regarding financial aspects, both the high cost of the welding processes and the fact that it adds an extra factor to the production process, an undesired circumstance occurs regarding the production cost and ease.
  • the system bottom cover connection is performed with screws. This system does not provide ease in use due to long screwing duration and also it causes difficulty in mounting-demounting processes due to reasons such as corrosion and blockage after a certain time of use.
  • the invention related to a structuring which fulfills the abovementioned needs, eliminates all existing disadvantages and provides some additional advantages.
  • the general aim is to prevent the breaks and detachment of the bottom cover by providing a regular distribution of the loads during the explosion and to provide the connection between the said 76 mm smoke grenade launcher chamber body and the bottom cover plenary by making the 3 numbers of segments center the segment channel by turning a crank arm which is located in the center of the bottom cover plenary.
  • This type of a connection shall prevent the breaks and detachment of the bottom cover by providing a regular distribution of the loads during the explosion.
  • Another aim of the invention is to enable an easy demounting of the bottom cover plenary from the said launcher chamber by turning a single crank arm and to increase the operating time by enabling the connection endure high tensions, in addition to prevent problems such as corrosion and blockage in the connection part.
  • Another aim of the invention is that the pins providing the connection to the contactor plenary body are located in the contactor and pin socket is perforated on the metal body. Therefore, the perforations which are opened to the contactor for the aim of decreasing the pressure by increasing the endurance are eliminated and the launching range is increased.
  • Another aim of the invention is to keep the powder gas and gas which pass through the perforations during the explosion inside the said launching chamber due to the fact that no perforations exist on the said contactor, therefore; to prevent exhaust gas and dust to enter into the base plate and consequently to enable the base plate remain clean.
  • Another aim of the invention is to produce the said launch chamber body from a one piece material and to eliminate the rounding problem and the production costs.
  • the present invention is a 76 mm smoke grenade launcher which is used in tracked or wheeled military armored vehicles for forming smoke shrouding, which comprises body plenary (23), bottom cover plenary (24), base plate (28), top cover plenary (27) contactor plenary (25), which inhibits the detachment and breaks of the bottom cover (24) by enabling the equal distribution of the explosion loads, which enables the launching pressure to remain high by the virtue of the contactor structuring, which enables the minimizing of the rounding by being produced from one piece metal and it is characterized in that, it comprises; at least three pieces of segment (4) which are connected to the crank (2) arm which exactly centers the segment socket of the bottom cover plenary (24)

  • 76 mm smoke grenade launcher of the invention which is seen in Figure 3, is used in tracked or wheeled military armored vehicles for forming smoke shrouding.
  • 76 mm smoke grenade launcher of which the general front view is given in Figure 3, generally is composed of body plenary (23), bottom cover plenary (24), base plate(28) and clamp (29) plenary, top cover plenary (27), and contactor plenary (25).
  • the base plate (28) that is seen in Figure 4 is the connecting element between the mortar launcher body plenary (23) and the armored vehicle it integrates onto.
  • the connection of the base plate (28) to the body is provided by the clamp (29) located onto it and second bolt (32).
  • FIG. 1 Front sectional view of the bottom cover plenary (24) of the invention is given in Figure 1 .
  • the function of this cover (1 ) is to make the launch unidirectional, to endure the pressure occurring during the explosion and to be demounted easily after launch to provide ease and quickness in cleaning.
  • the bottom cover plenary (24) includes three numbers of segments (4) located in a circular position and a crank (2) arm which is located in the center of the cover (1 ) which pushes the segments (4) out. Segments (4) which are connected to the crank (2) arm insert to the segment channel on the body plenary (23) by the movement from the crank arm and provides the connection between the body plenary (23) and the bottom cover plenary (24). With reverse movement, segments (4) are retracted and the connection is released.
  • first gasket (10) and the second gasket (13) are added to the bottom cover plenary (24).
  • Figure 7 depicts bottom cover plenary (24) in locked status.
  • the front sectional view of the contactor plenary (25) is provided in Figure 2.
  • the contactor plenary (25) serves to transmit electricity to the mortar ammunition and triggers the explosion with these electric signals. Since the ammunition is standard, the explosion results in 14 bars of pressure within the body (23). Due to the contactor pins (15) that are located onto the contactor top cover (14) which is made of plastic material and the pin sockets perforated to the metal body (23), the endurance is quite high. By this manner, the need for performing perforation onto the contactor top cover (14) is eliminated and the launching range is increased, as well as the pollution due to the launching gas entering the perforations is prevented.
  • the front view of the top cover plenary (27) is given in Figure 7.
  • the smoke grenade launcher For the aim of preventing pollution when the smoke grenade launcher is not used, it consists of a chain (36) of which one end is connected to the smoke grenade launcher, chain ring (35) and rubber cover (34) which provide the connection between the chain and the rubber cover (34).
