Dec. 4, 2023 — The sound a disc makes while soaring through the air is full of information about how fast the disc is flying and how quickly it spins. This inspired Kyle S. Dalton of Penn State University to ...
June 23, 2023 — Air taxis may be coming to our cities in the near future, but a new study warns regulations will need to address dangerous wind gusts around city buildings and other urban ...
June 12, 2023 — Researchers developed a machine-learning technique that can autonomously drive a car or fly a plane through a very difficult 'stabilize-avoid' scenario, in which the vehicle must stabilize ...
June 9, 2023 — Aerospace engineers designed a 1-megawatt electrical motor that is a stepping stone toward electrifying the largest ...
June 8, 2023 — New research shows that clear-air turbulence increased in various regions around the world from 1979 -- ...
June 7, 2023 — Researchers have revealed the mechanisms that cause lithium metal solid-state batteries to fail. The new insights could help overcome the technical issues with solid-state batteries, unlocking a ...
May 24, 2023 — The effects of the ground on propeller noise have now been measured ...
May 18, 2023 — Engineers have developed a prototype metamaterial that uses electrical signals to control both the direction and intensity of energy waves passing through a solid material. Potential applications of ...
Apr. 6, 2023 — There is extensive research on how a fixed-position flap affects lift in the realm of fluid-structure interaction. So, researchers conducted a bio-inspired study with a novel twist -- variable ...
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 ...
Mar. 30, 2023 — Researchers developed a multiagent trajectory planning system that guarantees a group of drones working together in the same airspace will avoid collisions even if their communications to one another ...
Mar. 28, 2023 — A team of scientists presents an original oscillating short-term memory model to study the dynamics of landing events at 10 major European airports. The model can estimate how landing volumes will ...
Mar. 21, 2023 — A new nano-barrier coating could help protect ultra-lightweight carbon composite materials from extreme conditions in space, according to a new ...
Mar. 15, 2023 — Researchers have developed resilient artificial muscles that can enable insect-scale aerial robots to effectively recover flight performance after suffering severe ...
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 ...
Feb. 27, 2023 — A cybersecurity technique that shuffles network addresses like a blackjack dealer shuffles playing cards could effectively befuddle hackers gambling for control of a military jet, commercial airliner ...
Feb. 8, 2023 — A research team has demonstrated the use of a novel control method in an aircraft with no tail. The technology allows an aircraft to be as smooth and sleek as possible, making it safer to fly in ...
Feb. 1, 2023 — Electric space propulsion systems use energized atoms to generate thrust. The high-speed beams of ions bump against the graphite surfaces of the thruster, eroding them with each hit, and are the ...
Jan. 25, 2023 — Allocating passenger aircraft emissions using airfares rather than travel class would give a more accurate idea of individual contributions, finds a new study. Including airfares in calculations ...
Jan. 24, 2023 — It was believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, need to be large to produce a lot of thrust. Now, a new study suggests that smaller Hall thrusters ...
