Hello to all, Naman Berry back here. If you are new to the blog, don’t forget to SUBSCRIBE to the blog, right after the post and if you wanna know me better, go on to the link below. https://airtravelexpert.weebly.com/about.html I recently have gotten a suggestion from one of my readers saying that I should also talk about planes, aviation news and flight innovation. Thank you very much for the suggestion. Today I will be talking about, one of the biggest things people do not understand about planes. What is that thing at the end of the wing and why is it there? It is known as a winglet and it is why you are able to fly long haul without stopovers. To introduce these, I will have to tell you some history as to who and why these were introduced. In the 70s, the world faced an oil crisis, which meant that there was a shortage of fuel although the demand was on a continuous rise. The US was also. Aviation fuel too was very expensive and it just was not affordable to run Long-haul flights, so many flights were cancelled. One of the famous ones being the El Al Boeing 747 flight to New York and to LA and San Francisco. So airlines had to start making all the money they could with Domestic and Short-to-Medium haul international flights. Flight prices soared and airlines started taking huge cost-cutting measures. This was causing a huge problem in the industry and now aircraft manufacturers had no option but to improve upon their aircraft designs to decrease fuel consumption rate. Boeing and Airbus now had no options but to put in money into research and development of new more efficient ways to fly aircraft. However, surprisingly the answer was found by Richard Whitcomb, A NASA researcher who came up with these “Upward curves on wingtips”, now known as the winglets or wingtip devices. These winglets have been found to be very useful parts of a modern-day airplane. Wingtips cause wingtip vortices, which is when high pressure air from below ‘bleeds’ onto the upper side of the wing which has a low pressure. This causes wingtip vortices, which is a form of induced drag. This increases drag and causes higher fuel consumption. However, with the help of winglets, this drag is significantly reduced and this helps increase efficiency of the aircraft by reducing fuel consumption rate. Many different winglets can help in recognizing the aircraft quickly. A plane with a split one at the end is an old A320 family plane (Round cockpit front). However, an upward curve with round front cockpit is a new A320 family member. These are known as Sharklets. An upward curve with shaped cockpit in front is a Boeing 737, but the new 737 MAX have split winglets known at “Split Scimitar Winglet” Below is a slide show that shows some other very famous and easily recognizable winglets. However, all this is now changing with the new Airbus A350, Boeing 787 Dreamliners and the upcoming Boeing 777X, successor of the very famous 777. They are giving away with these winglets and now coming up with a new generation of Blended winglets. These winglets are the ones that are not a special part of the wing but rather the wing itself bending to form the winglet at the tip. The Airbus A350 features very new upward curved blended winglets. This is one of the many reasons of the efficiency of the aircraft. The Boeing 787 Dreamliner features ‘raked wingtips’ which is where the tip of the wing is shaped and has a backward pointing tip. The same technology is being used for the 777X and this is a revolutionary winglet. These winglets have been proven to increase efficiency by reducing wingtip vortices. However, until now no winglet has proven to be flawless. Even though aircrafts have winglets, they still generate a lot of wingtip vortices. This problem is yet to be solved, an aircraft will leave wingtip vortices behind it. These are especially visible during landing and take-off. These two photos shows that this problem persists, but scientists and researchers are working on solving the problem. The solution will bring about huge changes, as this will increase efficiency even further and reduce fuel surcharges. This will allow longer routes; more aircraft efficiency will allow airlines to reduce flight costs. Hoping that you enjoyed this new special post about aircraft innovation. This new page will now be for special aviation news and innovation Huge Thanks to Maxime, for suggesting me to start this new news and innovation page on the blog.
