The Bible provides a famous slinger account, the battle between David and Goliath from the First Book of Samuel 17:34–36, probably written in the 7th or 6th century BC, describing events that might have occurred c. 10th century BC. The sling, easily produced, was the weapon of choice for shepherds fending off animals.
Slinger is an anti-drone weapon system developed by Electro Optic Systems (EOS) of Symonston, Australia.It was introduced in May 2023. [1] [2]It consists of: a remote controlled weapon station (RCWS) based on the EOS model R400 RCWS that uses a lightweight Bushmaster M230LF autocannon which is fully stabilised and capable of on-the-move operation. 150 radio frequency proximity fused, high ...
Features include an anti-hangfire system, a delinking feeder that exploits linked ammunition, and an extended-length barrel, which results in greater muzzle velocity and hitting power from the same M789 HEDP and NATO standard 30 mm ADEN/DEFA projectiles. The rate of fire is reduced to 200 rounds/minute and overall length decreased to 84.0 ...
A silver Peruvian atlatl from the 12th-15th century Atlatl in use. A spear-thrower, spear-throwing lever, or atlatl (pronounced / ˈ æ t l æ t əl / ⓘ [1] or / ˈ ɑː t l ɑː t əl /; [2] Nahuatl ahtlatl [ˈaʔt͡ɬat͡ɬ]) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface that allows the user to store energy during the ...
Darts can be propelled by a number of means. The atlatl uses leverage to increase the velocity of the dart, the kestros increases the range of propelled darts using a sling, and the exhalation of a person's breath through a blowgun propels small stone points or poisoned needles with pneumatic force.
Fig-4: Velocity Diagram of Pressure compounded Impulse Turbine. The velocity diagram shown in figure 4 gives detail about the various components of steam velocity and Blade velocity. where, symbols have the same meaning as given above. An important point to note from the above velocity diagram is that the fluid exit angle (δ) is 90⁰.
