Principle
The Panzerfaust 3 consists of a disposable launcher tube holding the projectile and a reusable firing and sighting unit. The projectile consists of a shaped-charge warhead filled with Amatol/Syndril and a shaft including the propulsion unit.
The Panzerfaust 3 can be fired from enclosed spaces since it does not have a significant backblast; the rear of the tube, filled with plastic granulate, minimises the blast effect by the so-called recoilless countermass principle. The booster propellant for the projectile in its tube is ignited by a bolt via a spring mechanism. Once ejected from the launcher, the projectile coasts a safe distance and then the rocket motor is ignited, boosting it to its maximum speed, after which it coasts until impact.
As safety precautions, the built-in fuse for the warhead is released by a safety mechanism. This arms the warhead after a flight distance of approximately five meters. Once armed, the warhead will detonate on impact, and as a safety when the rocket's propellant runs out. This safeguards against live ammunition staying around and causing hazards to all in the future. The Panzerfaust 3's name dates back to the Panzerfaust used by the German army in World War II, which consisted of a small, disposable preloaded launch tube firing a high explosive anti-tank warhead, operated by a single soldier.

Famous quotes containing the word principle:
“Experimental work provides the strongest evidence for scientific realism. This is not because we test hypotheses about entities. It is because entities that in principle cannot be ‘observed’ are manipulated to produce a new phenomena
[sic] and to investigate other aspects of nature.”
—Ian Hacking (b. 1936)
“Help thyself: then everyone will help thee too. Principle of Christian charity.”
—Friedrich Nietzsche (1844–1900)
“Custom, then, is the great guide of human life. It is that principle alone, which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past.”
—David Hume (1711–1776)
