Space Launch Vehicle SLV Rocket Design

Space Launch Vehicle (SLV) or Rocket Design is a complex process. The SLV or rocket design starts with the determination of what is the mission. A mission is something that the rocket or SLV is suppose to do. It could be to take a satellite or a space-craft into orbit.


It could be to take the spacecraft on an inter-planetary travel. It could be to take a man to the moon or Mars. Once, the mission, its attended goals and the payload required to be carried are worked out it is then possible to start with the design. As with any other design process the conceptual, preliminary and the detail design phase are worked out. It is worthwhile to note that weight of an SLV or Rocket and its payload is very important consideration. As only an addition of a single kg adds to thousands of dollars in the budget. Furthermore, safety is another very important consideration. Because huge amount of propellants are involved in rocket and SLV be it solid-propellant and liquid-propellant. Any defect in the grain of the propellant or leakage in any piping or O-range systems can be the cause of a sure disaster. So safety is taken very seriously in the design phase.


Safety is one of the prime consideration in the design. The design of the propellant system be it solid-fueled or liquid engine is very important. And the design of the nozzle is also carried out. Most of the time, designers choose to attach booster rockets to the main rocket. These add thrust in addition to the main rocket engines and are necessary to get the rocket off the ground. This enables designers to decrease the length of the SLV or rocket. Aerodynamic analysis and heating effects are also calculated using CFD and there results are extensively verified so as to meet the requirements. Furthermore, the rocket or SLV is flying at a very high Mach number, so it is essential that thermal protection especially to the nose cone is made. The nose cone is made blunt in many cases. This has the advantage that the shockwave is formed away from the nose and not on the nose tip. If the shockwave forms on the nose tip, the heating could be so large that it could melt the nose of the rocket.
