When aircraft are in flight, vortices are generated behind them from the wing tips. These are known as wake vortices, and they can have safety implications for following air traffic. The German ...

Recent research demonstrated that, although most wing shapes used today create turbulent wake vortices, wing geometrics can be designed to reduce or eliminate wingtip vortices almost entirely. In the ...

Since the early 1980s, I have had questions about an iconic picture depicting a dramatic, crimson wake vortex. This picture, with which my former NASA colleagues and I have a deep connection, provokes ...

The rotor wake of a helicopter comprises a system of interconnected vortical structures generated by blade tip circulation. The primary tip vortices dominate the near-field flow, convecting downstream ...

Investigators have not been able to explain why the captain of a Diamond Aircraft DA62 calibration flight repeatedly breached minimum separation distances from commercial traffic at Dubai before a ...

Differential flap settings and spoiler changes hold key for tackling hazard Researchers are planning flight tests of an Airbus A340-300 testbed in mid-2006 to evaluate the effect of differential flap ...

Due to the high operating speeds in cruise flight and the standard 1000 ft. vertical separation in RVSM airspace, wake can be encountered up to 25 nm behind the generating aircraft. Credit: ...

As an unavoidable consequence of lift a pair of counter-rotating vortices forms behind the wings. This long-lived vortex pair constitutes a potential risk to following aircraft. The proper prediction ...

The swirling wing vortex from an agricultural airplane is highlighed during tests at NASA's Wallops Flight Facility. NASA Langley Research Center Mark Mallari writes from Manila, the Philippines, with ...

Wakes can be encountered up to 25 nm behind the generating aircraft. The most significant encounters are reported within a distance of 15 nm. Credit: EASA Safety Information Bulletin 2017-10 Fast ...
