The aerodynamic performance of the quadrotor is usually suffering a lower propulsive efficiency in a windy environment. Especially the horizontal wind may affect the attitude control to provide ...

American defense contractor Bell was selected by DARPA to move forward with the build of its aircraft for the Speed and ...

Time-optimal control of a multi-rotor remains an open problem due to the under-actuation and nonlinearity of its dynamics, which make it difficult to solve this problem directly. In this letter, the ...

The rotors are the meat and bones of the entire craft. In a main and tail rotor configuration, the main rotor spins to create thrust that outweighs the helicopter's overall weight.

In this case, the Ohio Supreme Court concluded that bones are natural to chicken and that a reasonable consumer would expect to find a bone in a boneless wing.

It’s all wings and Westeros in this fiery combo of food and fandom. While digging into some seriously good chicken, we dive into everything Game of Thrones—favorite characters, wild plot ...

The study demonstrated that different multi-rotor configurations could produce similar total thrust for the same power input, validating the new criteria.

A Wings, Wheels & Rotors event is touching down at Executive Air near Bismarck Airport on Saturday, June 21.

This suggests the pattern we're seeing-longer wing bones in warmer climates-is driven primarily by the need for efficient cooling rather than heat conservation. "Even traits as critical as wings, ...

With another loss to the lineup, fans revealed their thoughts on the Wings losing Maddy Siegrist. "Dang. Poor Maddy. Her bones be having the worst luck in the W," a fan said.
