May 24, 2023 The effects of the ground on propeller noise have now been measured ...
Aug. 9, 2022 Researchers have developed an AI pilot that enables autonomous aircraft to navigate a crowded airspace. The artificial intelligence can safely avoid collisions, predict the intent of other aircraft, ...
Aug. 23, 2023 New algorithms for trajectory planning and control of fixed-wing 'tailsitter' aircraft are faster and more efficient than traditional quadcopter drones. The algorithms can execute ...
Mar. 15, 2023 Electrification is seen as having an important role to play in the fossil-free aviation of tomorrow. But electric aviation is battling a trade-off dilemma: the more energy-efficient an electric ...
Apr. 4, 2023 A research team has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This opens the way for large cargo ships borne across the oceans by wind alone, as ...
Jan. 17, 2023 A trapped mountaineer survived after enduring 16 frigid hours wedged in a crevasse on Denali (Mount McKinley) in Alaska. His long and difficult rescue in frigid conditions and care in the critical ...
Mar. 12, 2024 Researchers are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically. Researchers are developing new ...
June 18, 2021 An incredibly light new material can reduce aircraft engine noise and improve passenger comfort. The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic meter, making it the lightest ...
Dec. 12, 2023 Self-propelled nanoparticles could potentially advance drug delivery and lab-on-a-chip systems -- but they are prone to go rogue with random, directionless movements. Now, an international team of ...
Oct. 18, 2023 As the wind and rain pound the blades of a wind turbine, researchers carefully monitor screens, hundreds of kilometers away analyzing if the blade's coatings can withstand the onslaught. While ...
