SPACE CRAFT MECHANICS
The Mechanics of a Space ship has to be so precise in order for a successful mission in outer space. Below are the parts of a Space Ship that help astronauts reach outer space:
Engine:
The engine consist of two chemicals, fuel and a source of oxygen, called oxidizer. These two chemicals are combined and exploded in a combustion chamber. This combustion produces hot exhaust which is passed through a nozzle, therefore producing thrust. There are two main categories of rocket engines, solid engines and liquid engines. In a liquid engine, the propellants, the fuel and the oxidizer, are stored separately as liquids and are pumped into the combustion chamber of the nozzle where burning occurs. In a solid engine, the propellants are mixed together and packed into a solid cylinder.
Structure:
The frame of a rocket ship includes the cylindrical body, the fairings and any control fins. The function of the structural system is to transmit the loads from the forces generated during the flight and to provide low aerodynamic drag during the flight through the atmosphere. Rocket structures must be strong but lightweight and the performance of the rocket depends directly on the weight of the structure.
Guidance:
The Guidance system of a rocket includes very sophisticated sensors, on-board computers, radars, and communication equipment. This system is one of the most important components of a space ship as it helps the space ship exit the atmosphere and into space successfully. The guidance system also helps the space ship stay in orbit and keep orbital speed. This is important so that the ship doesn't get pulled back down to earth due to the gravitational pull.
Payload:
Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, munitions, scientific instruments, people, experiments, or other equipment. For example, the payload of a space ship can be a satellite, space probe, or spacecraft carrying humans or cargo.
