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 ...

It incorporates strips of fiber optic sensors that are mounted along the length of each rotor blade. As the helicopter flies, those sensors measure the strain being placed on the blade, along with any ...

UAVOS announced that it had completed flight tests of its advanced bearing-less rotor system installed on the UVH 25EL unmanned helicopter. Torsion bar is aimed to provide an effective damping action ...

Airbus Helicopters in the UK is exploring future activities to follow on from a four-year research project, in conjunction with Cranfield University, that has shown strong potential for advancing the ...

The science behind how helicopters turn midair is straightforward enough. Most of them usually come with main and tail rotors, which spin to create lift for the craft. This lift can be controlled by ...

Transport Canada and the FAA have issued an emergency airworthiness directives (AD) requiring main-rotor hub inspections of certain Bell helicopters following the fatal crash of a Bell 212 last month ...
