- Project Definition
- The purpose of our project is to determine if there is a relationship
between payload, engine efficiency and the weight of fuel of a rocket.
This will help determine the costs of sending a two-stage lower earth
orbit. This program also tests the engine efficiencies by varying
the exhaust velocity of the engine and also how it affects the fuel weight
and payload weight.
- Background
- The inspiration for this project came by the increase in technology and the growing need for more satellites as a result. Satellites play an important part in studies and measurements of the environmental phenomenon as well as gathering intelligence for agencies like the United States government and commercial corporations. National defense is also a growing concern with the events of September eleventh. When a space vehicle is launched into orbit, it needs to gain enough velocity to break away from the earth's gravity and atmosphere in order to get into lower earth orbit(LEO). The ability for rockets to escape the pull of gravity is called escape velocity. When an object is launched with an initial velocity greater or equal to the escape velocity, it will go up, but it will not come back down because its velocity was greater than the pull of gravity. Thrust is the force that propels an object forward.
