The defining features of a mortar are its responsiveness, high-angle arching trajectory (above 45°), low velocity and relatively short range. In the theatre of combat, mortars are used to kill military personnel, harass adversaries and prevent the use of ground with interdiction fire. They can also be used to lay smoke screens.(Photo credit: Israel Defence Forces) So, MOTAR’s DevSecOps pipeline combined with the application approval process will reduce the time needed to deploy simulations, digital twin, 3D models and training content through MOTAR, greatly reducing ATO timelines. Can you say #LevelingUp? The preferable mortar mix ratio for pointing is 1-part mortar and either 4 or 5 parts building sand. The ratio will vary depending Fly-K mortar systems – excellent stealth capabilities and tremendous tactical potential, archived from the original on 2023-03-14 When you start to explore the world of DIY, you’ll often hear the words cement and mortar spoken about. In fact, these terms are not interchangeable, and each has its own use. So, what is the difference between cement and mortar? Below we have summarised the two:

tiles being used. For example, any single lap tiles must be fixed mechanically with a nail or clip while double-lap tiles should Finely ground and mixed with lime it is a hydraulic cement, like Portland cement, and makes a strong mortar that will also set under water.

The Importance of a Good Key When Applying Mortar

M: This type of mortar is high strength, making it perfect for supporting heavy loads. It can be used for below grade masonry and works well on driveways. When it comes to the ideal conditions for working with mortar, these could be described as a “typical English summers day” e.g. slightly overcast and not too hot and even slightly damp but not raining.

Mortar: Mortar is a mixture that is made up using soft sand, sharp sand, cement and/or lime. Different types of mortar can be made using specific ratios of these other materials. The German Army studied the Siege of Port Arthur, where heavy artillery had been unable to destroy defensive structures like barbed wire and bunkers. As a result, they developed a short-barrelled rifled muzzle-loading mortar called the Minenwerfer. Heavily used during World War I, they were made in three sizes: 7.58cm (2.98in), 17cm (6.7in) and 25cm (9.8in).

Upotrebljava se u prehrani, za salate, ukiseljena i za umake, ali i u medicini kao antiskorbutik i diuretik. [1] MOTAR has a ton of core features and services for the development, hosting, and distribution of training applications – like Studio, Hub, and Training. In upcoming articles, we will take a deep dive into each of these features and services! According to the Geneva International Centre for Humanitarian Demining (GICHD), NATO member states, as well as countries supplied by western manufacturers, tend to use the 81 mm calibre medium mortar. Former Warsaw Pact members, and countries supplied by former Warsaw Pact states and China, tend to use the 82-mm calibre medium mortar. The 81-mm mortar projectiles are often longer and more aerodynamically efficient than the 82-mm versions, and commonly have a further range. The 120-mm calibre mortars are the most common heavy mortars in service globally. It is designed to be towed and is usually mounted on a vehicle, but it can be used as ground-mounted.

What is Mortar?

A spigot mortar consists mainly of a solid rod or spigot, onto which a hollow tube in the projectile fits—inverting the normal tube-mortar arrangement. At the top of the tube in the projectile, a cavity contains propellant, such as cordite. There is usually a trigger mechanism built into the base of the spigot, with a long firing pin running up the length of the spigot activating a primer inside the projectile and firing the propellant charge. The advantage of a spigot mortar is that the firing unit (baseplate and spigot) is smaller and lighter than a conventional tube mortar of equivalent payload and range. It is also somewhat simpler to manufacture. Further, most spigot mortars have no barrel in the conventional sense, which means ammunition of almost any weight and diameter can be fired from the same mortar. Most modern mortar systems consist of four main components: a barrel, a base plate, a bipod and a sight. Modern mortars normally range in calibre from 60mm (2.36in) to 120mm (4.72in). However, both larger and smaller mortars have been produced. The modern mortar is a muzzle-loaded weapon and relatively simple to operate. It consists of a barrel into which the gunners drop a mortar round. When the round reaches the base of the barrel it hits a fixed firing pin that fires the round. The barrel is generally set at an angle of between 45 and 85 degrees (800 to 1500 mils), with the higher angle producing a shorter horizontal trajectory. Some mortars have a moving firing pin, operated by a lanyard or trigger mechanism. Modern, high-explosive, mortar rounds are listed as both anti-personnel and anti-material weapons. The 120-mm mortar is powerful enough to penetrate buildings and destroy field fortifications. Rudimentary structures will often be completely destroyed by the initial blast wave, and provide little protection from fragments – allowing them to travel far greater distances.
