Nov 3, 2016 · What is the purpose of the vortex generators located right in front of the Boeing 737's windshield?

Sep 1, 2015 · In this high-speed situation, vortex generators can pull in high energy air from outside the boundary layer, mix it with air inside the boundary layer, and prevent separation. They can also disrupt the shock wave, reducing the amount of …

AFT BODY VORTEX GENERATORS. Vortex generators became an optional retrofit in November 1968 to reduce “vertical bounce” during cruise flight which was caused by airflow turbulence and separation from the body beneath the horizontal stabilizer.

The vortex generator helps only at high angle of attack by energizing the airflow between nacelle and wing. During cruise it will create additional drag without much benefit, especially if the nacelle-wing-combination has been designed well.

Mar 3, 2025 · Vortex generators (or VGs) are small aerodynamic devices that enhance the performance of aircraft, wind turbines, and even some ground vehicles. ... On a Cessna 182, a Boeing 737, or a transonic military jet, VGs help maintain control, delay stalls, and can help to improve the overall flight characteristics. And yes, they come with some trade ...

A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2] VGs may also be attached to some part of an aerodynamic vehicle such as …

Nov 4, 2010 · “The vortex generator successfully reversed the former negative pressure difference across the APU so that aerodynamic cranking could assist the starter motor during in-flight starts. The original VG did not work as well as expected so they added the trailing edge articulated flap which folds inboard 25 degrees when the APU is started and ...

An example of the vortex generator used aboard the current generation of the Boeing 737 family is pictured below. One generator is located on the inboard side of each nacelle. These devices can be seen aboard the 737-600, 737-700, and 737-900 in addition to the 737-800. Large vortex generator located on a Boeing 737 engine nacelle. Also note ...

Vortex generators are used under wing of Airbus A320 family aircraft to reduce noise generated by airflow over circular pressure equalisation vents for the fuel tanks. Lufthansa claims a noise reduction of up to 2 dB can thus be achieved.

Sep 2, 2020 · The 737 has one on each engine to help direct air away from the landing gear in certain configurations. IIRC, there was a buffet of the landing gear 'door' that was solved with a vortex generator. https://www.airliners.net/photo/Ryanair/Boeing-737-8AS/5343003/L. They even have vortex generators (strakes) on the Q400.
