The first modern research into military solid-propellant rockets in the United States was conducted by Colonel Leslie Skinner at the Aberdeen Proving Ground in 1932. Little interest was shown by the US Armed Forces however, until the introduction of a British anti-aircraft rocket; [4] both nations exchanged their research data before the United States entered World War II.
Mechanics are the base components of the game — its rules, every basic action the player can take in the game, the algorithms and data structures in the game engine etc. Dynamics are the run-time behavior of the mechanics acting on player input and "cooperating" with other mechanics. Aesthetics are the emotional responses evoked in the player.
The order of operations, that is, the order in which the operations in an expression are usually performed, results from a convention adopted throughout mathematics, science, technology and many computer programming languages.
A monopropellant rocket (or "monochemical rocket") is a rocket that uses a single chemical as its propellant. [1] Monopropellant rockets are commonly used as small attitude and trajectory control rockets in satellites, rocket upper stages, crewed spacecraft, and spaceplanes.
The Center for Simulation of Advanced Rockets (CSAR) is an interdisciplinary research group at the University of Illinois at Urbana-Champaign, and is part of the United States Department of Energy's Advanced Simulation and Computing Program. CSAR's goal is to accurately predict the performance, reliability, and safety of solid propellant rockets.
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
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]
A five-inch anti-aircraft shell was attached to the 3.5-inch rocket motor, creating the five-inch FFAR, which entered service in December 1943. Performance was limited because of the increased weight, limiting speed to 780 km/h (485 mph). [2] The high-velocity aircraft rocket, or HVAR, was developed to fix this flaw. [2]
