The Bot-Wing airfoil helps to smooth frontal air flow and redirects much of the “dirty” air away for a quieter, smoother and more enjoyable ride. The Bot-Wing is a logical, simple and effective add-on ...

A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

We’ve probably all experimented with a very clear demonstration of the basic principles of lift: if you’re riding in a car and you put your flattened hand out the window at different angles, your hand ...

The 777X will be a redesigned version of the 777-300ER, with extended range capability. The new design includes a swept-back airfoil wing fabricated in composite materials with increased thickness and ...

WASHINGTON, January 18, 2022 -- Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise ...
