Title: Pedro Paulet
Content: which he claimed legal ownership of his earlier rocket motor design. Recognizing that rocketry was beginning to boom in Europe, Paulet sought witnesses to help verify the work he said he had done years earlier. The letter was circulated across the world by an Alexander Scherschevsky, a Russian national, in summary form. Had Paulet's claim been authenticated, he might today be considered the father of liquid-propellant rocketry, rather than Robert H. Goddard, who in 1926, flew a liquid-fueled rocket engine in a test vehicle. Paulet also designed reaction motors in 1895, propulsion systems in 1900, and an airplane using thermoelectric

Title: Robert H. Goddard
Content: Robert H. Goddard Robert Hutchings Goddard (October 5, 1882 – August 10, 1945) was an American engineer, professor, physicist, and inventor who is credited with creating and building the world's first liquid-fueled rocket. Goddard successfully launched his model on March 16, 1926, ushering in an era of space flight and innovation. He and his team launched 34 rockets between 1926 and 1941, achieving altitudes as high as and speeds as fast as 885 km/h (550 mph). Goddard's work as both theorist and engineer anticipated many of the developments that were to make spaceflight possible. He has been called the man

Title: Liquid-propellant rocket
Content: solid fuel. The idea of liquid rocket as understood in the modern context first appears in the book "The Exploration of Cosmic Space by Means of Reaction Devices", by the Russian school teacher Konstantin Tsiolkovsky. This seminal treatise on astronautics was published in May 1903, but was not distributed outside Russia until years later, and Russian scientists paid little attention to it. Pedro Paulet wrote a letter to a newspaper in Lima in 1927, claiming he had experimented with a liquid rocket engine while he was a student in Paris three decades earlier. Historians of early rocketry experiments, among them

Title: Rocket engine
Content: twenty-five. This was the birth of the modern rocket engine. He calculated from his independently-derived rocket equation that a reasonably sized rocket, using solid fuel, could place a one-pound payload on the Moon. He began to use liquid propellants in 1921 and was the first to launch, in 1926, a liquid-propellant rocket. Goddard pioneered the use of the De Laval nozzle, lightweight propellant tanks, thrust vectoring, the smoothly-throttled liquid fuel engine, regenerative cooling, and curtain cooling. During the late 1930s, German scientists, such as Wernher von Braun and Hellmuth Walter, investigated installing liquid-fueled rockets in military aircraft (Heinkel He 112,

Title: Liquid-propellant rocket
Content: Max Valier, Willy Ley, and John D. Clark, have given differing amounts of credence to Paulet's report. Paulet described laboratory tests of, but did not claim to have launched a liquid rocket. The first "flight" of a liquid-propellant rocket took place on March 16, 1926 at Auburn, Massachusetts, when American professor Dr. Robert H. Goddard launched a vehicle using liquid oxygen and gasoline as propellants. The rocket, which was dubbed "Nell", rose just 41 feet during a 2.5-second flight that ended in a cabbage field, but it was an important demonstration that liquid-fueled rockets were possible. Goddard proposed liquid propellants
