A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, with a rapid convergence and gradual divergence. It is used to accelerate a compressible fluid to supersonic speeds in the axial (thrust) direction, by converting the thermal energy of the flow into kinetic energy .
An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed . [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.
The AS.12 originally entered service with the French Navy in 1960 in the air-to-surface role against ships and submarines on the surface. In 1966 the French Navy made an evaluation of the SS.11(M) and SS.12(M) from the fast patrol boat La Combattante. [1] In 1966, the Libyan Navy ordered three fast patrol boats from Vosper (Sebha, Sirte and Susa).
The propelling nozzle converts a gas turbine or gas generator into a jet engine. Power available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. The power is defined by typical gauge pressure and temperature values for a turbojet of 20 psi (140 kPa) and 1,000 °F (538 °C). [18]
Air jet loom. An air-jet loom is a shuttleless loom that uses a jet of air to propel the weft yarn through the warp shed. [1] It is one of two types of fluid-jet looms, the other being a water-jet loom, which was developed previously. [1] Fluid-jet looms can operate at a faster speed than predecessor looms such as rapier looms, but they are not ...
A multi-axis thrust vectoring engine nozzle in motion. Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.
An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate. Whether the valve opens or closes depends on ...
Snapper, Inc. is an American company, formerly based in McDonough, Georgia, that manufactures residential and professional lawn-care and snow-removal equipment.Snapper is known for their high-quality products, including rear-engine riding lawnmowers capable of standing on end for storage or repair, and for their invention of the first self-propelled rotary lawn mower.
