Credit: CC0 Public Domain Sustainable fuel blends used by aircraft may help reduce the impact of aviation on climate warming by producing less contrail cloud, concludes a study published in Communications Earth & Environment. The findings suggest that contrails from aircraft burning sustainable fuel blends could contain 50 to 70% less […]

A proposed hybrid-electric plane could “eliminate aviation’s air pollution problem,” say MIT engineers. Proposed design could reduce nitrogen oxide emissions by 95 percent, a new study finds. At cruising altitude, airplanes emit a steady stream of nitrogen oxides into the atmosphere, where the chemicals can linger to produce ozone and […]

Virgin Galactic unveiled its design for a supersonic aircraft and announced a partnership with Rolls-Royce to build the engine. Space tourism company Virgin Galactic on Monday announced a partnership with engine-maker Rolls-Royce to build a supersonic commercial airplane that flies at three times the speed of sound. The aircraft would […]

Reverse-engineering birdflight helped researchers create a powerful new kind of drone. Shutterstock We have developed four-winged bird-like robots, called ornithopters, that can take off and fly with the agility of swifts, hummingbirds and insects. We did this by reverse engineering the aerodynamics and biomechanics of these creatures. Our ornithopters have the […]
