Description. MESKO SA is the largest producer of ammunition, anti-armour and anti-aircraft missiles in Poland. STRIX is fired like a conventional mortar round. The early idea and complex design was the German mine launcher, Minenwerfer but the archetype of a mortar was the British Stokes design in 1915 which was a simple tube with a fixed firing pin at the bottom end, where a bomb was dropped and … USE: The 120mm Mortar High Explosive and Smoke (white phosphorous (WP)) rounds were developed for use in the M120 and M121 120mm Mortar System. www.nammo.com globalsales@nammo.com4 5 Core Business Ammunition Nammo is a superior quality producer of small, medium and This cartridge is an illuminant round developed for use in the M120 and M121 120mm mortar system. mortar With the rod cranked back, it could be released to impact and ignite the propellant charge located on the mortar round. This cartridge is a high explosive round developed for use in the M120 and M121 120mm Mortar System. The round was a slip fit, loaded into the tube from the muzzle. Chapter 9.5 Explosives and solid propellant safety - NASA The SRTR is designed to be fired, recovered, refurbished, and refired. These were used in the M2 Mortar. 922103, 922104 What are the two types of tank shells? The vehicle would be parked, pointing roughly at the target. As a former Mortar Fire Controller (MFC) in the British Army I can add a little to this discussion. The 4.2" mortar's big difference compared to the 81mm is that the 4.2's round is rifle stabilized while the 81 is fin stabilized. The shell contains a perforated The Strix mortar round is a Swedish endphase-guided projectile fired from a 120 mm mortar currently manufactured by Saab Bofors Dynamics. Since its qualification in 1985, WC 819 has been the propellant of choice for all U.S. 81mm mortar ammunition. WC 863 (Military Designation-M47) is a newly developed and qualified BALL POWDER® Propellant for the U.S. 120mm mortar ammunition family. Mortar ammunition is considered semi-fixed because the propelling charge is adjustable. On 60mm rounds, bags of granular or horseshoe-shaped propellant are attached to the fins or boom. All 60mm mortar rounds, except training rounds, have three major components - a fuze, body, and tail fin with propulsion system assembly. A mortar ammunition component consists of a fuze, a cartridge, propellant charges and the fin assembly. Make An Offer. The propellants GD’s Ordnance and Tactical Systems division makes for 60mm, 81mm and 120mm mortar systems increments are flash-suppressed and clean burning, which results in minimum residue, flash, and blast overpressure, important for the safety of the mortar team. SUBSTANCE: main ignition charge comprises an extended paper cartridge with a metal base with the ratio of length to diameter equal to 5.5÷6.5, where an igniting cap is installed. The round contains an infrared imaging sensor that it uses to guide itself onto any tank or armoured fighting vehicle in the vicinity where it lands. Download scientific diagram | Mortar round with propellant charges on the tail assembly. The 120mm mortar will replace the aging, heavy 4.2 inch mortar system currently in use. The burn rate of the foamed celluloid can be enhanced by the addition of energetic additives, such as energetic plasticizers. This cartridge is a high explosive round developed for use in the M252 improved 81mm mortar system. Propellant charge of mortar round comprises main ignition charge placed in mine stabiliser extended chamber. Some rounds may also have exterior propellants added before the round is used. Mortar round with propellant charges on the . The most efficient burn occurred in a 34-cm diameter by 11-cm deep bowl, which contained the charges, separating them from direct contactwiththeenvironment.Over70%oftheresidueswere The design of the mortar bomb. On 60mm rounds, bags of granular or horseshoe-shaped propellant are attached to the fins or boom. For soldiers looking to use these mortar rounds as a grenade, they had to remove the safety pin and slam the tail of the mortar round against something solid to simulate the force of the weapon firing. The 4.2-inch mortar, M30 ( Figure 6-2 ), is a rifled, muzzle-loaded weapon with the mission to deliver high-angle, indirect fire. BAE Systems and General Dynamics Ordnance and Tactical Systems have teamed to develop, demonstrate, and produce the 81mm Roll Controlled Guided Mortar (RCGM), an affordable 81mm precision mortar round. A complete round of mortar ammunition contains all of the components needed to get the round out of the tube and to burst at the desired place and time. Mortars may be initiated by a fixed or, more commonly, removable ignition cartridge (sometimes referred to as a propelling cartridge), which features a pyrotechnic primer. With some, you simply drop the round in, it hits … An ordnance technician holds a propellant wafer following its removal from the back end of a 4.2-inch mortar round. Since the mortar normally is fired from defilade, the indirect fire team gathers and applies the required data for firing. Additionally, many mortar projectiles may be fired with an adjustable propellant load. The round is fired from the mortar the same as service ammunition. With a full increment charge and a 6.87-pound M43A2 high explosive round, the M1 mortar could hit a target almost 3,300 yards away, giving it a significant range advantage over the 60mm M2 mortar. 1 / 2 Show Caption + Hide Caption – To test the M47 propellant, a wax projectile is used for firing out of the 120 mm mortar. from publication: Energetic Residues From Live-Fire Detonations of … As each tube fired only one round, mortars were usually deployed as a battery of four or six welded onto a steel frame. The mortar operator had relatively little control over where the shell landed, but despite this mortars increased in popularity and are still used today. Propellants in the closed canister ignite and burn in a I dont have my charge books to check the nomenclature but the round would usually say C4 instead of TNT as well as give the type of fuze and type of round on the side. 'Hang Time's' or Time of Flight as we knew it, depends on the range you are firing at, and of course the number of propellant charges attached to the base of the mortar round. ramine propellant, providing significant advantages for the 81mm mortar, be- yond just extending range. MORTAR, 81mm, HE, M821 Use. A round for the M252 mortar comes with four charges attached. Three modes of operation, GPS/IMU, SAL+GPS/IMU and GALLERY PICTUREP90-2 Mortar ammunition is considered semi-fixed because the propelling charge is adjustable. Solid propellant and propellant, as used in this chapter, mean the same thing. It is intended for use against personnel and material providing both blast and fragmentation effect. The round is dropped down the tube, and the weight of the round is enough to set off a #209 shotgun primer inserted in the base of the round. The companies have been maturing the guided mortar technology over the last 12 months and will be conducting tactical demonstrations early in 2012.

The early idea and complex design was the German mine launcher, Minenwerfer but the archetype of a mortar was the British Stokes design in 1915 which was a simple tube with a fixed firing pin at the bottom end, where a bomb was dropped and … The propelling charge in a mortar round is usually contained in a closed canister, or at least includes an igniter propellant in a closed container. Mortar Rounds Freed of Propellant Wafers. Longer-range shots require more propellant than can fit in the tail of the round, hence the necessity of external charges. Each square is referred to as a charge. Essentially, a mortar works a lot like any other firearm. referred as a charge, and had a charge attached to each fin by a small metal clip. An economical, low residue, mortar increment propellant container manufactured of foamed celluloid, which is composed of 50 to 84% nitrocellulose, having a nitrogen content of from about 10.5 to about 13.5%, and about 15 to about 50% camphor. The weather was nearly . More than 97,000 mortar rounds are in their original packaging and will go through baseline reconfiguration to prepare them for processing by the plant’s automated system. Your average 120mm tank round weighs 22 kg (48-49 pounds) and contains about 8 kg (17-18 pounds) of propellant. This meant a safety pin had to be removed followed by a sudden force such as the propellant exploding to fire the round from the tube. Mortar ammunition is considered semi-fixed because the propelling charge is adjustable. Characteristics of the 82 mm Mortar Bomb. Share. The agent is sealed in the munition with a steel burster well.
