Strake (aeronautics) - Wikipedia
Nacelle strakes. On jet aircraft where the engines are mounted in nacelles slung under the wings, strakes may be added to one or both sides of each nacelle to produce vortices that energize the airflow over the wings in times of high angle of attack, such as during takeoff and landing, thus improving wing effectiveness. Ventral strakes.
Aircraft Vortex Generators - The Nacelle Strakes - GridPro Blog
2021年10月14日 · Nacelle strakes are small delta-shaped or triangular panel sheets positioned strategically on the nacelle to induce longitudinal vortices. In short – vortex generators mounted on nacelles are called strakes.
What Are The Tiny Wings On The Side Of Aircraft Engines?
2023年6月28日 · These nacelle strakes can induce stable longitudinal vortices to redirect and reenergize the airflow over the engines and back upwards to even the upper part of the aircraft wings, generating essential lift as compensation.
