  • Engineers fly first-ever plane with no moving parts
    on November 23, 2018 at 6:51 pm

    Engineers have built and flown the first-ever plane with no moving parts. Instead of propellers or turbines, the light aircraft is powered by an 'ionic wind' -- a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady flight.

  • Could an anti-global warming atmospheric spraying program really work?
    on November 23, 2018 at 6:50 pm

    A program to reduce Earth's heat capture by injecting aerosols into the atmosphere from high-altitude aircraft is possible, but unreasonably costly with current technology, and would be unlikely to remain secret. Those are the key findings of new research which looked at the capabilities and costs of various methods of delivering sulphates into the lower stratosphere, known as stratospheric aerosol injection (SAI).

  • Optimizing airport flight patterns take a toll on human health
    on August 15, 2018 at 4:40 pm

    Health costs associated with noise from changing flight patterns over populated urban landscapes far outweigh the benefits of reduced flight times, according to a new study. The researchers used flights from LaGuardia airport that have historically flown over Flushing Meadows and the U.S. Tennis Center in Queens - known as the TNNIS route -- as a case study to explore the trade-offs between more efficient flight routes and suffering on the ground. […]

  • New aircraft-scheduling models may ease air travel frustrations
    on June 11, 2018 at 5:35 pm

  • Computer linguists are developing an intelligent system aid for air traffic controllers
    on March 8, 2017 at 4:48 pm

    Human lives depend on their decisions, and psychological stress levels are high. An average radio contact takes 3.5 to 11.3 seconds, during which the air traffic controller checks in with the pilot, examines the radar screens and gives out new instructions. The current technical support systems typically lack the ability to understand and process these brief radio exchanges. […]
