Definitions
- the 105 mm howitzers M101 and M2 were the light field howitzers of the United States for a long time and were used extensively in European and Pacific war zones during World War II.
- the 105 mm family was completed by the air-loaded version M3, which was based on the M2 system, but had a 690 mm shorter barrel and a more effective reverse brake.
- the M3 howitzer could fire the same ammunition as the M2 version, but because of the shorter barrel more explosive powder had to be used for the drive. Production of the M2 and M3 systems started in 1941. In use, these weapon systems impressed with their high accuracy.
- the LG1 should also be mentioned as another 105 mm howitzer system in widespread use.
- This modern system is also outsourced, is valued for its low weight and high target accuracy with a relatively long range and is produced by GIAT Industries (now the Nexter Group).
- This system is available today still active in the armies of Belgium, Canada, Colombia, Indonesia, Singapore and Thailand.
- the maximum possible amount of gas is released to accelerate the projectile in the gun barrel, so that the powder burns off at a relatively high pressure level, which may go as far as the system limit of the 105 mm howitzer system used. Since the powder burnup is accelerated significantly by higher pressures, the powders used in the higher loads must be designed accordingly, i. H. they have to react much more lazily compared to the powders of the deep charges.
- the propellant charge system to be protected can in principle also be used in other artillery caliber areas, e.g. in 155mm systems.
- the wall thicknesses of the powders used would have to be adjusted in a manner known to those skilled in the art.
- the resulting powder has the following physical properties: 4.66 mm outer diameter, 9.03 mm length, 1.05 mm mean wall thickness and 0.15 mm hole diameter, 3653 J / g heat content and 957 g / l bulk density.
- the novel charge build-up consisting of the combination of two powder types according to the invention with and without surface treatment, i.e. with the second inert plasticizer diffused in and without the second inert plasticizer diffused into the deep charges 1 - 2 in the cold region, only very small drops in the muzzle velocity occur, namely - 5.9 m / s in zone 1 and 8.6 m / s in zone 2.
- the energy conversion into kinetic Energy is very efficient both in Zone 1, where only the powder is used without surface treatment, and in Zone 2, where the combination of both powder types is used with and without surface treatment, which results in high thermal efficiencies of 33% (Zone 1) and 32% (Zone 2) expresses, despite the low peak gas pressures of ⁇ 500 bar.
- the amount of powder was set in such a way that a muzzle velocity of 652 m / s results at 21 ° C.
- the peak gas pressure that arises for this speed is only 3371 bar, ie the ratio v 0 / p max is, as hoped, relatively high.
- the pressure reserve of 600 bar could be used if necessary to increase performance by means of an additional charge for increased range.
- the Fig. 1 shows a propellant charge system 1 according to the invention with six partial charges 2.1, 3.1 - 3.5.
- the partial loads 2.1, 3.1 - 3.5 are each filled in an essentially cylindrical cloth bag.
- the propellant charge system 1 shown comprises five second partial charges 3.1-3.5 with a second powder type as the drive, which in the region of near-surface zones has a penetration depth of at most 400 micrometers between 2 to 10 percent by weight of a second inert plasticizer.
- the propellant charge system 1 further comprises a first partial charge 2.1 with a first powder type as the drive, which has no second inert plasticizer in zones near the surface.
- the first part load 2.1 serves to cover the lowest area of the shot board, while the second part loads 3.1 - 3.5 can cover the upper areas of the shot board.
