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 the engines of some Airbus family 320, MAX and if you haven't noticed it tooén 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 inspired by the búwith and their feathers.
That being said, chevrons are the patternósaw-tooth pattern seen on the trailing edges of some jet enginesón. As the hot air of the núengine cleo mixes with air más fríor blowing throughés of the engine, the profiled edges serve to smooth the mixture, which reduces turbulence which in turn generates noise.
The Boeing 787 It is located among the airplanes más that are based on chevrons to reduce engine noise levels with «teeth» in the nacelles or in the fan housings. the boeing 747-8 It has chevrons on both the nacelles and the nozzles of the No. 1 engine.úinternal cleo.
At first sight, chevrons seem to be a solutionón elegant, but the designñor simplistic appearance masksñthe experimental onesón that were based on a set of research toolsóin constant evolutionón to correct mistakes along the way.
At the moment this technologyía is used 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.
