Robert H. Goddard was a scientist, and a U.S. professor of physics. As a child he had many problems with disease. On March 16, 1926, he became the first person in the world to build and launch a liquid-fueled rocket. From 1930 to 1935 Goddard launched rockets that attained speeds of up to 885 km/h (550 mph). Though his work in the field was revolutionary, he was sometimes ridiculed for his theories about space flight. As a child, Goddard was a thin and frail boy who was almost always in fragile
Nozzle A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In nozzle velocity of fluid increases on the expense of its pressure energy with decreasing pressure. Nozzle have many types and each of them has special uses. The nozzle types are high velocity, propelling
Auk 1: During the late 1950’s the space race began. This was a race to see who could achieve the most space firsts, between the USA and Russia. Sonny, O’Dell, Sherman, Roy Lee and Quentin live in Coalwood, West Virginia.The space race inspired these boys, who decide to call themselves the Rocket Boys, to make their own rockets. The BCMA (Big Creek Missile Agency) was born when Sonny called a meeting with his friends in his room and discussed how he wanted to build rockets. With the help from the
CHAPTER 1 SPACE LAUNCH SYSTEM : GENERAL STAGES BOOSTERS PROPOSED MISSIONS WHAT IS THE SPACE LAUNCH SYSTEM? The Space Launch System (SLS) is NASA’s new heavy launch vehicle. It is to replace the retired Space Shuttle. Its initial Block I version, without an upper stage, is to lift a payload of 70 metric tons to orbit. The final Block II version is to have a payload lift capability of at least 130 metric tons to low earth orbit, 12 metric tons above that of Saturn V, which would make the SLS the
exclaimed. ‘The same as you, old chap! If I learn how to build a rocket, I’ll stand a better chance of getting on down at the Cape’” (Hickam 70). Lastly, he constantly improved the design of his rockets. Homer Hickam was in charge of calculating the De Laval nozzles’ design and the launch of the first rocket bearing his design is described as: “It [The Rocket] flew straight, slicing without flinching through the plane of the mountaintops. Sherman counted. ‘Ten, eleven, twelve …’ I watched as the smoke trailed
