I want to clarify that I'm a fan of Santos Dumont, and think he should be honored and remembered for what he did. He was a brave, intelligent, and noble man. He solved many problems regarding use of gasoline piston engines on aircraft which caused the French to jump ahead of the world in aircraft engine technology in the early 1900s. He also gave France a head start in airframe building skills with his airships, along with his 14Bis and 14Bis-2. So once they knew the secrets of the Wrights they could jump into building airplanes with both feet and get the lead on the rest of the world. Just because I don't think he invented the airplane doesn't mean that I don't think he should be remembered as a hero.

People also forget the Wrights invented the wind tunnel and had to correct lots of data regarding airfoils. People simply fail to realize just how much work the Wrights did to advance aviation. Airfoils, wind tunnels, propellers, engines, 3 axis control, etc. Their attempts at secrecy and trying to patent all of aviation was a mistake afterwards though. I've read the Wright Flyer was capable of crossing the Mediterranean before Bleriot even crossed the English channel for example. And Wilbur had been offered $5000 to cross the English Channel as well, but refused claiming it was a wreckless stunt. Wish he'd just asked if one of his pilots was interested. The Wright Flyer was superior to so many other designs for many years. But I agree none the less, others did contribute to the advancement of aviation and should be recognized for that. I myself didn't know that much about Dumont prior to this video. What is interesting to me is that many people, Wrights included, had successfully flown heavier than air gliders for many years prior to 1903, but it was the "powered" heavier than air flight that was important. With multiple people achieving glider flight, it baffles me that so many others didn't seem to pay attention to the gliders, and what enabled them to fly. Seems many "hop" designs didn't pay much attention to the gliders. Considering this was a key part of the Wrights approach, I wonder if anyone else would have gotten closer than they did had they paid attention to those a bit more. But, many gliders had little to no control either, so perhaps not. The Wrights just asked the correct questions that others never did, as stated in the video.

And sadly this trend will go on into the foreseeable future. They even teach us THAT Dummont invented the worst watch with Cartier, something which had already existed for some time. I grant you that he was indeed a visionary for his own time, had wonderful ideas about in any number of fields. His house in a city called Petrópolis is nothing short of amazing, and very excentric, but his vision regarding airplanes and the future weren't way too idealistic. A great man, but definitely not the first to fly and some people over here have a bit of a problem understanding that.

The discussion about the Wright brothers is only led by people, who don't care to look at the knowledge and engineering performed by the respective individuals.

I asked how could he comply with a standard that didn't exist in Cayley made no claim to being the first to fly. It was just an experiment to satisfy his curiosity. He is said to flown 900 ft. using an 8 hp engine and his chauffeur as his test pilot. His conclusion was that the technical requirements for manned flight would take time. He didn't specify a date but other aviation pioneers predicted that manned flight would be achieved as early as 1950. in the 1800's, few believed that manned flying machine was possible. Cayley correctly predicted (c. 1800) that sustained flight would not occur until a lightweight engine was developed to provide adequate thrust and lift. The Wright brothers acknowledged his importance to the development of aviation. Sir George Cayley, (1773 - 1857) was an English engineer, inventor, and aviation pioneer. en.wikipedia.org/wiki/George_Cayley

It is refreshing to watch a video made by a guy who really knows the depth of the Wright's story. The propeller is often forgotten as a great achievement. You will recall that even Charley Taylor said "I don't think the boys got enough credit for it." Another forgotten aspect of their work was the realization that a person needed to "learn to fly." The Wright's work was not based on trial and error, but when something didn't work they still had to decide if it was the aircraft or the pilot's fault.

The Wright's strength was experimentation with models and developing the science before proceeding fusing theory and experimentation. They were not merely tinkerer inventors but methodical engineers. An excellent debunking video for those who do not understand the engineering of aviation especially the fluid dynamics and mechanical design. Prior to this people built what looked good without getting quantitative and scalable data as the Wright's did than their predecessors as well as developing knowledge of the material science to actually build the craft.

Their conclusion, the Wright Flyer could not possibly fly. Drag would be greater than Thrust. We know that a spring scale was used to measure static thrust on the 1903 flyer. Does anyone know how much thrust a ceiling fan can produce? It uses flat paddle props so it can't be very efficient.

Excellent work, you treat the Dumont-Wright situation fairly and clearly researched this extensively. Eagerly waiting for the next documentary.

I always admired Santos Dumont Demoiselle airplane as an flying object of fragile beauty. I understand later in life Santos was greatly grieved and outraged when he witnessed airplanes being employed to bomb people. He really was a brave and sensitive soul when it came to flight.

Good video as always. I don't blame Dumont for being pissy about having the record stripped from him. He spent his life trying to accomplish what no man has before, he and every else believed he had done it. Then it gets stripped and he is told someone else did it better and a year before him. I know I wouldn't have the humility to admit defeat.

Hey there fellow aviation nerds - I am one of you and also a former amateur bicycle racer from the times of power meters. Watt output is heavily tied to body size and weight. It’s very similar to gasoline engines. More displacement is analogous to more muscle and a larger frame. Elite male cyclists with height and weight above average, along with thorough conditioning can produce a steady 300 watts or more for as long as 30 minutes. Cycling usually does allow for periods of rest and recovery, so using a long flat course like a triathlete would use might give the best comparison to aircraft engines. 800+ watts output is what would be measured in a sprint or burst of effort. Once again muscle mass is heavily in play. The most powerful sprinters are track racers and road race sprint specialists. The best professionals can ride over 100 miles continuously in a group, and produce 1600+ watts for several seconds at the end.

The Wright Brothers were under-appreciated. They contributed greatly to aerodynamics, control, props... The brothers depended on other highly touted inventors data for wing design which was faulty so they built a primitive wind tunnel and wrote the book on lift for their wings.

The Wright brothers deserve sainthood. They only attended high school, were only bicycle mechanics, and they effectively applied the scientific method to change the world.

I have found that the opposite of the cliche true: "Never attribute to stupidity, that which is adequately explained through malice." The original cliche of dismissing any notion of malice is too often the escape of the cowardly. Pardon the presumption, but I think Greg has been well aware of the possibility that the misrepresentations are intentional, rather than innocent "mistakes". That the actors are well aware that their arguments are in bad faith. The same has been true of many such lies in aviation history. One of the more famous ones involve the lies about the Moon Landing being "faked". What's important about these lies is to duly recorded and repeatedly plastered on the people who trumpeted them. Even now, everyone from former Jewish Nomenklatura to Japanese Aeronautical engineers are trying to foist their slander on the shoulders of a single American engineer of all things - eager to pretend they were victims rather than perpetrators. The attempts to sully the achievement of the Moon Landings were mostly foreign in origin and drive in worldwide media, academia, and yes professional culture (even American engineers and pilots disgraced themselves and sold out their country by shrinking back at the accusations of their supposed foreign "colleagues", rather than turning their backs on these ). They know that to continue pumping out new Lies, their old Lies need to be forgotten or swept away - like a Global Cooling/Warming/Change Con-Artist hoping the new generation never learns of their long, unbroken record of failed predictions, prognostications and deceptions. Thus the importance of histriography; to record not just the original history and how its telling changes over time, but also the LIES about history and how THEY change over time. It is important to remember the Truth - and those who were Wright. The flip-side is that it is also important to remember the Lies - and the Liars.

Excellent video, as always! I love the relatively recent biography of the Wrights and appreciate you used you channel to shine a bit of light on their work.

Just found this, the best channel on YT I now know of, particularly for those with a technical interest. Thank you, Greg!

As usual, a well researched, well made video. I learn more watching an hour of your videos than I could by watching 10 hours of History or Discovery on the same subject.

Thank you so much! I've been thirsting for a deep dive into the design of propellers and why they are the way they were/are. And who better than you to do it! I am eagerly waiting for the next installment!

Greg, regarding the Wright Flyer having more than 12 hp on 12/17/1903, here's an excerpt of the book The Wright Flyer, an Engineering Perspective, that provides more detail about the subject: _"The required modifications of historically accepted numbers for engine power and propeller efficiency can be made without difficulty. Four factors must be taken in account: (1) Engine power, with cooler air of higher density, would be higher than static tests indicated; (2) engine cooling, on a cold day in flight, would be much more effective than in static tests, and the engine's output was highly dependent on cooling, because of the unjacketed valve cages and cylinder heads, as witness the decline in power as the engine warms up (see Reference 26); (3) induced drag was less than wind-tunnel measurements because of ground effects at the very low altitudes at which the flights took place; and (4) propeller efficiency was obviously higher than the Wrights' estimate of 66%, which included an exaggerated transmission loss as the result of Chanute's misinformation (see Reference 24) to the effect that chain losses would be 25-30%.The Wrights figured 10-15%, while the true losses were probably closer to 5%._

@marcelojenisch4258

3 күн бұрын

The same book shows a contemporary writing of Orville Wright describing what happened with the engine power during their static tests: _"Due to the preheating of the air by the water jacket and the red-hot valves and boxes, the air was greatly expanded before entering the cylinders. As a result, in a few minutes' time, the power dropped to less than 75 percent of what it was on cranking the motor. The highest speed ever measured was 300 turns (1,200 rpm) in the first fifteen seconds after starting the cold motor. The revolutions dropped rapidly and were down to 1,090 rpm after several minutes' run."_ The Brazilians critics are essentially correct when they say the Wright Flyer could not fly with just 12 hp. And indeed it could not, as the Wright Experience wind tunnel data demonstrated (it needed a minimum of 16 hp to fly). It is just a shame that many of the Brazilians critics use this information to jump to the conclusion that it proves the aircraft never flew. As we have seen, the aircraft actually had 16 hp or more. That's why it flew. The flaw the Brazilians critics are incurring is one of deductive reasoning. Their premise is that the Flyer's engine had 12 hp. And since this premise is false, their conclusion also becomes false.

I would like to add one more thing that makes me very annoyed: people ignoring propeller efficiency and only speaking about brake horsepower. The propeller is an extremely important aspect when evaluating an airplane's performance. And even more so in the machines of the pioneer era of aviation. Thrust horsepower is the horsepower that really matters for an airplane. Thrust horsepower is brake horsepower mutiplied by the propeller's effiency. Poor propeller efficiency = most of the brake horsepower is lost. For instance, the propeller efficiency of the 14-bis is unknow, but I read a Brazilian paper giving estimates of 20 to 50%. Let's pick 35% and do the math. With an engine of 50 brake horsepower and a propeller efficiency of 35%, the thrust horsepower value is just 17,5 hp! Most of the brake horsepower is lost! That's why just speaking that Dumont had a powerful 50 hp Antoinette is not enough. Now, let's pick an engine of 20 hp with a propeller efficiency of 80%. How much thrust horsepower it will produce? 16! Nearly equal to the Antoinette with the inefficient propeller! But of course, horsepower is not the only aspect that needs to be evaluated in an engine. Still, one can see that when speaking of airplanes, just making horsepower comparisons is wrong!

​​​​@@GregsAirplanesandAutomobilesIndeed. I have read in the same Brazilian academic paper I mentioned in my previous comment that even using a propeller with an efficiency of just 20%, the 14-bis produced some 157 pounds of thrust at 26 mph. That represents a thrust horsepower of just 10 hp. With several cylinders, I guess the Antoinette created a lot of torque. It is just a shame that most of the brake horsepower was lost with the poor French propellers.

As usual a very fair and thorough examination of the subject. I especially like that you didn’t just diminish Dumont but did give him credit he deserved. Well done.

I was about to be all "What, nothing about the literal century old french airplane still flying?" when I remembered that was more 1910/1911 than the *EARLY* stuff in the 19-single-digits.

I can’t believe that I (of all people) have to correct a glaring misstatement about Dumont’s propeller: it doesn’t look like a double bladed oar AT ALL. It looks like a double bladed (kayak) paddle. Oars are fixed to the boat by a pivot point, paddles are held in the hands, single blades are canoe paddles, double ended ones are kayak. ;) With that tongue-in-cheek internet overreaction quibble out of the non-Wright (wrong?) propellers really do look like kayak paddles and whitewater ones at that. Those are something I used to use often before shoulder injuries told me to take it easy. Finally, and by far most importantly, I love your channel and it’s content. Please keep up the excellent work.

I'm just here commenting to prop up Greg's algorithm. As usual you have done a fantastic job screwing into the issues at hand and you even kept yourself from spinning off into the stratosphere by getting distracted with issues not salient to the rarefied air these early pioneers of flight lifted themselves to. Well done Greg and well worth the wait. That float plane example you showed has always been a favorite piece of aircraft history. Impressive performance and technology came out of that endeavor!

I believe Ader's Avion 3 probably did make a brief uncontrolled hop before 1900. Dumont's 14bis's "flight" wasn't much more than an extended version of that. However, I can't understand how anyone could claim that the 14 bis made the first heavier than air flight in history when over a year earlier the Wrights could stay aloft for over half an hour in sustained controlled flight. This is a documented historical fact that's not up for debate. My only argument, and it's a weak one at that, is that the early Wright flyers seemed to be so dependent on weather conditions (that is, density altitude) so not totally practical in that you couldn't fly whenever and wherever you wanted. Still, they were so far ahead of everyone else and of course, things improved with better engines.

Fantastic info on the DR-I...never knew that!

"Aerodynamics for Naval Aviators" is the pilot's edition of the "Junior Woodchucks' Guidebook", isn't it?

If one can hold interest long enough, this is the most informative collection of details on early flight! Really great. Not just flying. Design. Motors. Weight. And the elusive propeller. Great history here.

As always I learned a lot from the depth of knowledge disseminated by this video. I have heard that both Santos Dumont and even Manley were credited by some as the inventors of the aeroplane and have been correctly (as it turns out) suspicious. Having learned so much from this video it is more clear than ever that the Wrights deserve the credit. More importantly the claim in the book 'Visions of a flying machine" that the Wrights discovered aerodynamics first and built their glider and planes based on that makes more sense than ever. Thank you, I feel empowered to quietly and confidently disagree with bar-room experts who claim that Santos Dumont should have the laurels now.

Terrific video. Love your work. It is curious how much resistance there is to giving the Wrights the credit they deserve. Their work is impressive, addressing problem after problem with hard work and talent. As you point out, they were not richly financed and just kept on going in the face of adversity.

Bravo Greg! In as limited an area possible the Wrights development of propeller design demonstrated the depth of their understanding of aeronautics and their careful, methodical pursuit of flight. When they flew they didn't do it by chance! They could show their work, so to speak, in clear numbers and calculations. I credit the fact that they had limited resources for the project and HAD to get the details right before they could build the flyer. They could not afford to guess!

中井久夫 : "Something about the 14 Bis is just beautiful." I think box kites are beautiful and box kite wings with dihedral are extremely stable and practical. It is interesting that Hargrave did not stick with his box kite design. He proved that adding camber to the surfaces of the kite doubled their lift and that there was enough lift with multiple celular wing kites to suspend a man above the ground. The Voisin company that built the box kite winged float plane glider added a lot of wire and change the look of the box kite. The airframe that he gave to Santos Dumont lacked a motor and a refined control system. "Santos Dumont's airframe was built by Voisin and was based on his speedboat towed box-kite winged pontoon glider. It had a fix box kite in the front. Dumont could have specified that he wanted to add pilot control to the forward box kite. I have found no information on that. It may have been intentionally hidden. The flight of the modernized Bis 14 look alike replica was also a thing of beauty. Its flight in the hands of a pilot with 1000's of hours in the air would not be he same as a pilot with less than 15 min. of fight training. It was much smoother and the control surfaces seemed to actually work. Still Santos Dumont's flights were still a thing of beauty to the spectators at the game field.
