Lab Reflection and Analysis A. Background Rockets date back to the early 1200, where they were used in China. Warlords would experiment with gunpowder and arrows. The first rockets were actually made by they Chinese, they were 12 arrows placed in a funnel like basket and the end was lit. This primitive invention was named Rocket Propelled Fire arrows (David Harding, 1980). Although the real rocketry started in about 1250 and 100 years later RPGs (Rocket Propelled Grenades) were introduced to the world by Europe and they Arabs (David Harding, 1980) Modern rockets are used for many things like weapons, space travel, recreation, experiments, and many other things. In the way of rockets used as weapons, there are many types. There are air defense missiles, SAMs (Surface to Air Missiles), ballistic missiles, air to land missiles, air to air missiles, and many other types. As you see there is almost a missile for everything. One of the newest and most effective missiles that we have is the Tomahawk Cruse missile. Cruise missiles are designed to fly at extremely low altitudes at high subsonic speeds, and are piloted over an evasive route by several mission guidance systems. The name of the main guidance system is TERCOM (Terrain Contour Matching), this guidance system is so effective that a cruise missile can hit its designated target within 6 feet and can be launched from extremely long ranges (The United States Navy Fact Files, 1998-200). In terms of recreation model rockets are what people use. Model rockets generally use solid fuel, such as Estes rocket engines etc. Model rocketry is actually a big hobby for some people. It involves building the rocket, this means taking time and carefully preparing all of the parts of the rocket to be put together. Once the rocket is successfully built you must put in an engine and an igniter. The engine sizes run as followed A half stage, A...
