1. Rocketnoun

   any flying device propelled by the reactive force of hot gases expelled in the direction opposite its motion. The fuel used to generate the expelled gases in rockets may be solid or liquid; rockets propelled by liquid fuels typically have a combustible fuel (such as hydrogen or kerosene) which is combined inside the rocket engine with an oxidizer, such as liquid oxygen. Single liquid fuels (called monopropellants) are also known. Since rocket engines do not depend on a surrounding fluid medium to generate their thrust, as do airplanes with propellers or jet engines, they may be used for propulsion in the vacuum of space.

1. Rocket

   A rocket (from Italian: rocchetto, lit. 'bobbin/spool') is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology for the Space Age, including setting foot on the Moon. Rockets are now used for fireworks, missiles and other weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight, and space exploration. Chemical rockets are the most common type of high power rocket, typically creating a high speed exhaust by the combustion of fuel with an oxidizer. The stored propellant can be a simple pressurized gas or a single liquid fuel that disassociates in the presence of a catalyst (monopropellant), two liquids that spontaneously react on contact (hypergolic propellants), two liquids that must be ignited to react (like kerosene (RP1) and liquid oxygen, used in most liquid-propellant rockets), a solid combination of fuel with oxidizer (solid fuel), or solid fuel with liquid or gaseous oxidizer (hybrid propellant system). Chemical rockets store a large amount of energy in an easily released form, and can be very dangerous. However, careful design, testing, construction and use minimizes risks.

1. Rocketnoun

   a cruciferous plant (Eruca sativa) sometimes eaten in Europe as a salad

2. Rocketnoun

   damewort

3. Rocketnoun

   rocket larkspur. See below

4. Rocketnoun

   an artificial firework consisting of a cylindrical case of paper or metal filled with a composition of combustible ingredients, as niter, charcoal, and sulphur, and fastened to a guiding stick. The rocket is projected through the air by the force arising from the expansion of the gases liberated by combustion of the composition. Rockets are used as projectiles for various purposes, for signals, and also for pyrotechnic display

1. rocket

   The well-known pyrotechnical preparation, but modified to suit various purposes. A cylindrical case charged with a fiercely burning composition, the gases of which, rushing out from the after-end against the resisting atmosphere, propel the whole forward at a rate continually increasing, until the composition be expended. It is generally kept in balance by a long light stick or tail attached. The case is made of metal or paper, and variously headed to the amount of 32 lbs. if its purpose be war (see CONGREVE-ROCKETS); life-saving (by conveying a line over a stranded vessel); even the killing of whales, when reduced to 1, 2, or 3 lbs.; or, lastly, signals, for which it is fired straight upwards.
