A pencil detonator or time pencil is a time fuze designed to be connected to a detonator or short length of safety fuse. They are about the same size and shape as a pencil , hence the name. They were introduced during World War II and developed at Aston House , Hertfordshire , UK .
Artillery Time fuzes detonate after a set period of time. Early time fuzes were igniferous (i.e. combustible) using a powder train. Clockwork mechanisms appeared at the beginning of the 20th century and electronic time fuzes appeared in the 1980s, soon after digital watches. Almost all artillery time fuzes are fitted to the nose of the shell.
A shot timer is a shot activated timer used in shooting sports, which starts the competitor by an audible signal and also records the competitor's time electronically by detecting the sound of each shot, together with the time from the start signal. When the competitor is finished, the timer will show the time from the start signal until the ...
Time on target (TOT) is the military co-ordination of artillery fire by many weapons so that all the munitions arrive at the target at roughly the same time. The military standard for coordinating a time-on-target strike is plus or minus three seconds from the prescribed time of impact.
Lock time or action time refers to the time interval (often measured in milliseconds) from when the trigger of a firearm is activated until the firing pin strikes the primer, and depends on the design of the firing mechanism. A long lock time increases the probability of the shooter pulling the sights away from the target before the bullet has ...
Cooking off (or thermally induced firing) is unfired weapon ammunition exploding prematurely due to heat in the surrounding environment. [1] [2] The term is used both for detonation of ammunition not loaded into a weapon, and unintended firing of a loaded weapon due to heating. A fast cook-off is a cook-off caused by fire.
Chappell Roan’s huge summer just got bigger. The 26-year-old rising pop star garnered an unprecedented-sized crowd at the Lollapalooza music festival over the weekend, according to organizers.
An unintentional discharge is the event of a firearm discharging (firing) at a time not intended by the user. An unintended discharge may be produced by an incompatibility between firearm design and usage, such as the phenomenon of cooking off a round in a closed bolt machine gun, a mechanical malfunction as in the case of slamfire in an automatic weapon, or be user induced due to training ...
