Some reading for the summer “Boeing Max 8 Part 2”
Coanda, Bernoulli & Newton
The first Coanda effect airplanes flew 100 years ago to England and were flying wood and canvas shacks. Physics engineers sometimes did not understand and still do not understand any of this, imagine the pilots. Take a look at this aircraft built by Coanda in 1910, known for being the first Coanda effect aircraft and also for being the first in history to be powered by a jet engine. It was equipped with a Coanda effect compressor and Coanda effect wings. A copy was exhibited in France "the plane really flew!" But Coanda who was at the controls was unable to govern it and destroyed it on landing. Reading is believing: https://it.wikipedia.org/wiki/Coandă-1910 Many texts do not mention Coanda because after Coanda no one understood anything until the usual Americans pulled out the Dyson curlers and now everyone pilots who fly around the airfields think that the Coanda is the Panda's bad brother. Regarding the physical laws that revolve around the wing, there is no law that drives out the other, in reality some laws are dominant in certain areas, others in others, we just need to find out which law dominated our Frankestain "Boeing Max 8" . For example, no Bernoulli versus Coanda makes sense but simply when the wing surfaces become critical or super critical "I would say saving wings" then a Bernoulli law that applies to particular dimensions of the wing profile (air flowing above and below the profile) is reduces when there is little difference between the upper and lower surfaces of the wing and then the angle of attack becomes a dividing line to create a Coanda effect that can replace the Bernoulli effect. In practice, even a traditional wing at the same speed can be subject to the Coanda but Bernoulli are so predominant as to make the Coanda negligible. When the wing is super critical, the "incidence" angle of attack is the right one and temperature, pressure, density and even humidity. Then the super-critical "saving" wing can only substitute the Bernoulli effect with the Coanda effect. They always coexist but in non-overlapping areas. With regard to Coanda, very little media coverage was held in the West. The same thing happened for all the great geniuses of the East: Mendeleev, Kurciatov, Tsiolkovsky Korolev, Miliutinovich and many other great scientists who had the exact same treatment reserved for Coanda. The reason is not known or at least understood but it is still an indisputable fact that a part of the great story is deliberately kept silent. A resounding example "Minkovsky" who knows him? Answer: The mathematician who co-authored Einstein's theory because Einstein was a saw in mathematics and asked for help from Minkovsky and his rotating space-time. Have you ever heard of it? No, if you don't read university texts you can't know. Do we want to talk about Tesla? Who more than him was mistreated for 100 years? https://www.youtube.com/watch?v=IbMlU5POTt0
For example, the “Bumblebee” has been flying much better than the DASH-8 for at least 100 million years without ever crashing like the DASH-8 does. The error in the calculations that showed that the hornet could not fly was that of applying the laws of physics to a "standard" flight that did not correspond to the wing motion of the hornet. By the way ... to the physics of Bernoulli and Coanda it was also necessary to apply Newton's law which tells us that: "to every action there is an equal or opposite reaction" in fact the wing pushes the air down and sideways that's why The frankestain also has winglets in the wing tips “induced drag”. The hornet moves the air down exactly as an airplane wing does. Since 2005 there has been a filmed test of the hornet applies the above laws at least 250 times per second for each wing "has 4". https://www.youtube.com/watch?v=9_hVVRw8cOA&t=111s Hope you will enjoy my deduction of the fistic law around the Max8 “Frankestain”.
Bumblebees are amazing, so we filmed them in 4k slow motion (Ultra HD) 4K resolution, while they were hard at work.Bumblebee and other types of bees are extr...
