Demonstration of a blowgun by a Yagua hunter. A blowgun (also called a blowpipe or blow tube) is a simple ranged weapon consisting of a long narrow tube for shooting light projectiles such as darts. It operates by having the projectile placed inside the pipe and using the force created by forced exhalation ("blow") to pneumatically propel the ...
Formation of an EFP warhead. USAF Research Laboratory.. An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance.
In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder.

This Saturn IB second-stage Auxiliary Propulsion Unit is similar to one used on the Saturn V third stage, which performed as an ullage engine for translunar injection. Ullage motors (also known as ullage engines or ullage rockets ) are relatively small, independently fueled rocket engines that may be fired prior to main engine ignition, when ...
A cold gas thruster (or a cold gas propulsion system) is a type of rocket engine which uses the expansion of a (typically inert) pressurized gas to generate thrust.As opposed to traditional rocket engines, a cold gas thruster does not house any combustion and therefore has lower thrust and efficiency compared to conventional monopropellant and bipropellant rocket engines.
Project Orion in the 1960s envisioned the use of nuclear shaped charges for propulsion. The nuclear explosion would turn a tungsten plate into a jet of plasma that would then hit the drive pusher plate. About 85% of the bomb's energy could be directed into the target as plasma, albeit with a very wide cone angle of 22.5 degrees.
All the propulsion elements are pressure fed rocket engines burning UDMH and N 2 O 4 with a common supply of pressurized propellant. [1] Mechanically, the KTDU-80 is separated in two sections: Basic Unit (BB) (Russian: ББ, Базовый Блок): It is the main propulsion and includes all propellant pressurization and storage system. It is ...
Astronaut propulsion unit, a device used to move an astronaut relative to the spaceship during a spacewalk; Dynamite gun, any of a class of artillery pieces that use compressed air to propel an explosive projectile; Gas pistol, a non-lethal weapon used for self-defense and other purposes
