Transcript of Rockets
History of Rocketry
Polish artillery expert published drawings of a staged rocket
As early as 1806, payloads were sent up by rocket that used parachutes to recover them.
Tsiolkovsky, a Russian school teacher, published a report in 1903 that suggested the use of liquid propellants for rockets in order to achieve greater range. Tsiolkovsky stated that the speed and range of a rocket were limited by the exhaust velocity of escaping gases.
This device is called Hero's Engine - it is considered the first steam engine and the first example of jet propulsion.
In 1232 AD the Chinese used rockets against the Mongols who were besieging the city of Kai-fung-fu. An arrow with a tube of gunpowder produced an arrow of flying fire.
In January 1958, a modified Redstone rocket lofted the first American satellite into orbit just 3 months after the Von Braun team received the go-ahead. This modified Redstone rocket was known as a Jupiter-C. Its satellite payload was called Explorer I.
April 12, 1961, Soviet, Yuri Gagarin, became the first man in space.
The Saturn V, first launched on November 9, 1967, was the most powerful member of the Saturn family producing as much power as 85 Hoover Dams. The crowning achievement for the Saturn V rocket came when it launched Apollo 11 astronauts to the moon in July 1969.
A new era in space flight began on April 12, 1981. That's when the first Space Shuttle mission was launched.
The Shuttle was designed to carry large payloads into Earth orbit.
On October 4, 1957, the nation was shocked when the Russians launched Sputnik, the world's first artificial satellite.
Congreve rocket, artillery rocket developed by Sir William Congreve and first used in 1806. The rockets were used effectively during the Napoleonic Wars and the War of 1812.
In 1926, Goddard launched the first liquid-fueled rocket and laid the foundation for a technology that would eventually take man to the moon and beyond. Fueled by liquid oxygen and gasoline, Robert Goddard's rocket flew for only 2.5 seconds, climbed 41 feet, and landed 184 feet away in a cabbage patch.
Model Rocket Pieces
The nose cone is the tip of the rocket. It is the aerodynamic leading edge for the rocket and it also helps deploy the recovery system, allowing the rocket to come back to earth softly.
An elastic or Kevlar shock cord is connected to both the body tube and the nose cone and is used to keep all the parts of the rocket together during recovery. The paper mount attaches the cord to the body tube.
Provides for a safe recovery by slowing the descent of the rocket so it lands on the ground softly and can be used again.
Fins keep the rocket heading in the right direction. Without fins, the rocket will become unstable. Most rockets have three or four fins, but larger rockets can have more.
The body tube is the main component of the rocket that holds the internal parts of the rocket and keep them from falling out. It also separates the nose cone from the fin section - if they are too close, the rocket could be unstable when launched.
The engine mount in a model rocket is located at the bottom of the rocket and houses the engine, holding it in place during flight.
A bent piece of metal with a small angle at one end which holds the engine securely inside the engine mount.
Launch lugs slide over the launch rod on the launch pad and are used to guide the rocket on its first few feet of flight until sufficient speed is developed for the fins to stabilize the model because we cannot steer the rocket.
May 5, 1961, a Mercury-Redstone vehicle boosted America's first astronaut, Alan B. Shepard on a suborbital flight.
