A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust by the reaction of the rocket to the ejection of fast moving fluid exhaust from a rocket engine. Chemical rockets create their exhaust by the combustion of rocket propellant. The action of the exhaust against the inside of combustion chambers and expansion nozzles accelerates the gas to extremely high speed and exerts a large reactive thrust on the rocket (since every action has an equal and opposite reaction). The history of rockets goes back to at least the 13th century, and military and recreational display use dates from that time. Widespread military, scientific, and industrial use did not occur until the 20th century, when rocketry was the enabling technology of the Space Age, with man visiting the moon. Rockets are used for fireworks and weaponry, ejection seats and launch vehicles for artificial satellites, human spaceflight and exploration of other planets. While inefficient for low speed use, they are, compared to other propulsion systems, very lightweight and powerful,capable of generating large accelerations and of attaining extremely high speeds with reasonable efficiency. 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.

GNU Free Documentation License How do you put together a Bandit model rocket? Q. I'm building a rocket for physics. I put it together using Krazy Glue, but my teacher later mentioned that Krazy Glue would not be strong enough, and I would need a stronger kind of adhesive. He specified a few sections of the rocket, but I don't recall what these parts are. Which parts do you think need stronger adhesive? And what is a good, cheap adhesive you know of? Asked by ciabatta - Fri Oct 17 00:25:21 2008 - - 1 Answers - 0 Comments A. For a bandit, it's balsa fins and a cardboard tube, basically. Yellow wood glue is best for this type of rocket. You'll want to make sure you put good glue joints everywhere. On the centering rings where they attach to the motor tube, and to the body tube to keep the motor tube from detaching and shooting up through the rocket. On the fin/body tube joints to keep the fins on under thrust, and on the shock cord mount inside the body tube to keep it attached so your rocket comes down with the parachute. Since everything is already together, just put "fillets" on all the joints. Make a small puddle of wood glue on a piece of paper, and use a toothpick to spread the glue against all the joints, making sure you have enough glue to hit… [cont.] Answered by loopy_markvan - Fri Oct 17 12:55:00 2008 Where can I launch a model rocket from in Baltimore? Q. I've been at Johns Hopkins for the summer and a friend of mine suggested that we build a model rocket. I now have the rocket but don't know where to launch it. Does anyone know of any parks in Baltimore(particularly those close to the Johns Hopkins Homewood campus) where model rockets can be launched from?
