May 17, 2022 Researchers assessed the potential impact of a rocket launch on atmospheric pollution by investigating the heat and mass transfer and rapid mixing of the combustion byproducts. The team modeled the ...
Aug. 2, 2021 A vital piece of gas engines, combustors -- the chambers in which the combustion powering the engine occurs -- have the problem of breaking down due to fatal high-frequency oscillations during the ...
Feb. 14, 2023 When the Artemis 1 mission was launched in November, it became the world's most powerful rocket, and with liftoff came a loud roar heard miles away. Researchers report noise measurements during ...
Aug. 23, 2022 Abundant internet claims about the acoustic power of the Saturn V suggest that it melted concrete and lit grass on fire over a mile away, but such ideas are undeniably false. Researchers used a ...
June 10, 2021 New research used a system for monitoring nuclear tests to track the infrasound from 1,001 rocket launches, identifying the distinctive sounds from seven different types of rockets. In some cases, ...
