2018 - The Electron rocket was the first New Zealand rocket to achieve orbit. The rocket is also unique in using an electric pump-fed engine. The rocket also carried an additional satellite payload called "Humanity Star", a 1-meter-wide (3 ft) carbon fiber sphere made up of 65 panels that reflect the Sun's light. [35]
The first rockets were used as propulsion systems for arrows, and may have appeared as early as the 10th century in Song dynasty China. However, more solid documentary evidence does not appear until the 13th century. The technology probably spread across Eurasia in the wake of the Mongol invasions of the mid-13th century.
For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...
Pratt & Whitney Rocketdyne (PWR) was an American company that designed and produced rocket engines that use liquid propellants.It was a division of Pratt & Whitney, a fully owned subsidiary of United Technologies Corporation.
On July 19, 2006 Rocketdyne announced that the demonstrator engine front-end had been operated at full capacity. [3]According to NASA, the Integrated Powerhead Demonstrator project was the first of three potential phases of the Integrated High Payoff Rocket Propulsion Technology Program, which was aimed at demonstrating technologies that double the capability of state-of-the-art cryogenic ...
The V. P. Glushko Museum of Cosmonautics and Rocket Technology is a memorial museum telling about the beginning of the domestic space engine industry, including the history of GDL. The museum is located in the Peter and Paul Fortress, which in the 1930s housed GDL stands for testing rocket engines. It was opened on April 12, 1973.
The RS-68 (Rocket System-68) was a liquid-fuel rocket engine that used liquid hydrogen (LH 2) and liquid oxygen (LOX) as propellants in a gas-generator cycle. It was the largest hydrogen-fueled rocket engine ever flown. [3] Designed and manufactured in the United States by Rocketdyne (later Pratt & Whitney Rocketdyne and Aerojet Rocketdyne).
In the early 1930s, Forman and Parsons began to realize that the rocket technology was a more complex subject than they had first assumed. [6]: 64–66 They corresponded with rocketry experts on both sides of the Atlantic, but Forman later reminisced that they learned very little beyond the fact that nobody else had yet achieved much.
