We continue reviewing some curiosities of the industryéarea and on this occasion we will know whaté They are the chevrons or teeth that the engines of some planes.
Thanks to the contribution of all of you on my social networks and your weekly participation.ón in space Let's talk about Aviación on YouTube, post ideas are born in response to the doubts and concerns expressed in these channels.
about días publicé about cóhow to identify a Boeing 737 MAX versus other B737 family aircraft, and one of its main characteríStatic teeth are a type of teeth that have their motors on the back of them.:
Before this publicationón, doubts arose as to whyé los motores del algunos Airbus familia 320, MAX y si no lo han notado también del Boeing 747-8 and Boeing 787 they have these teeth and whyé serving, hereí the answer:
¿Para qué chevron or teeth work?
First we must indicate that it is a technologyíThe idea is from NASA, which together with other industry players found a designñwhich mainly allows, reduce noise emitted by engines, but inspirados en los búhos and their feathers.
Dicho esto los chevrons son el patrón de dientes como sierra que se ve en los bordes posteriores de algunos motores a reacción. A medida que el aire caliente del núcleo del motor se mezcla con el aire más frío que sopla a través del motor, the profiled edges serve to smooth the mixture, which reduces turbulence which in turn generates noise.
The Boeing 787 se encuentra entre los aviones más modernos que se basan en chevrones para reducir los niveles de ruido del motor con «teeth» in the nacelles or in the fan housings. the boeing 747-8 tiene chevrones tanto en las nacelles como en las boquillas del motor del núcleo interno.
At first sight, los chevrons parecen ser una solución elegante, pero el diseño de apariencia simplista enmascara años de experimentación que se basaron en un conjunto de herramientas de investigación en constante evolución para corregir errores en el camino.
Por el momento esta tecnología es utilizada úonly by Boeing and not by other manufacturers such as Airbus that at the time may apply their own solution.ón.
¿Whaté It's a chevron?
Okay, First of all they are not teeth although they look similar and the shape técynically correct way to call them is chevron or chevrons in plural.
Being a word in Englishéwith su definitionón is an insignia used on flags or military uniforms, police and others that it is a V that is generally used inverted.
