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 projectile.
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 ...
A para-athlete competing with a match air rifle A collection of lever-action, spring-piston air rifles. An air gun or airgun is a gun that uses energy from compressed air or other gases that are mechanically pressurized and then released to propel and accelerate projectiles, similar to the principle of the primitive blowgun.

the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
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.
The development was completed by the end of the 60s. In 1971, Il-76MD with the propulsion unit on the basis of four D-30KP was demonstrated to the country’s leaders. In 1972, engine passed certification tests and then was presented to the public at the next international air show in Le Bourget (France).
