The 1950s were a time of rapid innovation in aviation. The world emerged from World War II with an intense curiosity about ...

Helicopters can deliver military troops or rescue the wounded in tight spaces, but their rotating blade design also puts a hard limit on their speed and maneuverability. Now researchers have begun ...

For about 76 years, helicopters have served the world as an important alternative to fixed-wing aircraft. Helicopters can go places and do things that airplanes cannot, like save mariners stuck at sea ...

Although helicopter aerodynamics involves the same forces that arise in airplane aerodynamics, these forces occur differently due to fluid flow dynamics across the aircraft. Helicopters take advantage ...

Researchers at the DLR Institute of Aerodynamics and Flow Technology are able to measure complex flow phenomena such as those that occur on helicopter rotors, and to evaluate the resulting data ...

A conversation between a Virginia State Police helicopter pilot and his trooper co-pilot before a crash that killed both of them referred to an aerodynamic phenomenon that a National Transportation ...

High-speed helicopters don't have to be fuel-draining sound machines. A new rotorcraft design was presented by Airbus Helicopters at the Paris Air Show this week, and Airbus claims it can reach a ...
