Hello. Were going to go through a tour of some artifacts that really stand out in terms of the story of higher, faster, and farther. First, i would to talk about the museum overall. It has over 8 million visitors a year. Looking at the story of flight in the atmosphere, where i work in, we are looking at 500 aircraft and helicopters. About 67 are on display in the National Mall building. What supports these artifacts are up to 50,000 small and medium artifacts. Were going to talk about the story of higher, faster, brother. A bit of a cliche in the history of aviation but has a real meaning. We look at the people who made this quest of flying in the third dimension a reality. The idea of flying to the highest altitudes, faster speed, longest distances tells us a lot about the Technical Development of the airplane and the reinvention of what the right brothers Wright Brothers did. Only the smithsonian can tell the story. Behind me, you see the wright flyer. Orville wright, at the controls takes flight Orville Wright takes flight. The first time. At the end of the day, after four flights, oracle orville and wilbur alternate. 30 miles per hour. At an altitude of 30 feet. They usher in the aerial age. How they came to create that moment is very important. Not only did they invent the airplane, they invent aeronautical engineering in the process needed to create actual flying machines. In 1899, the brothers, they are unmarried and owned they own a printing business. They are yank you mechanics. They know tools and devices. They take that interest and apply to printing presses, bicycles, and solving the problem of building a flying machine. In 1899, they write the Smithsonian Institution and ask for all of the literature on flight. They learned about the predecessors of aerial navigation. They learned about the secretary of the smithsonian who will be their competitor. What sets the right brothers apart is that they break the problem down. We have to look at an airplane as a system of systems. Looking at propulsion, structures, control and aerodynamics. The science of flight. Between 1899 and 1902, they start flying gliders. They start with tights, than with gliders. By 1902, they have a controllable glider. Theyve made a new fundamental contribution called wing warping. Rather than use your way to shift the glider, they have a mechanical system where they can twist the wings. How they come to that conclusion is that the brothers always complemented each other as intellectuals. They argued how we control this airplane . How will we make it move in the air . How can we keep it from just flying in a Straight Line . In the bicycle shop, wilbur is talking to a customer and has in inner to box for bicycle tire and twisting it as hes talking to the individual. Theyre all about nonverbal talking in the minds i imagining that three dimensional quality. If we start twisting the wings of our glider, it will turn. Thats how they come up with these new ideas about what an airplane is. They create the worlds first working win tunnel. They took the math of previous experimentalist and found out hes wrong. They recalculate the coefficient of the wing and design wings that are capable of creating lift. By 1902 they have a working glider flying multiple seconds. They travel there because it is the one spot in america that has consistent winds as well as isolation so they can work without distraction. Through 1902 in 1903, they add the last big part of the airplane. Theyve done the wings, the aerodynamics. Theyve done the structure which has been influenced by their predecessors. You look at the control system of wing warping. The last ingredient is the propulsion system. They acknowledge it is going to be a reciprocating piston engine. They tailor their mechanic in the bike shop and create a horizontal engine. They know they need that much power to generate the thrust of the propellers. That is another very specific choice the right brothers make. Its having propellers on the flying machine. How do propellers work . They figure they can go to existing ship propellers and that does not give them any answers. The same sort of intellectual given take the brothers have between each other and realize that a propeller is a rotating wing. They take the wind tunnel data, adapted for design of a propeller and design to propellers that are capable of producing up to 67 to 70 thrust. A 12 horsepower engine. You see the propellers on the back of the wings. They wanted them to turn in opposite directions to counter rotate. Taking their knowledge of working in a workshop. Taking their knowledge, you twist the belt of the power system. You can see one of the trains chains twisted on the drive system. The propulsion system enables the brothers to go to kitty hawk in the late fall early winter where they start their online program. They have a crash and on december 17, 1903, they fly this airplane hymie. Behind me. That moment of getting behind into the air and looking at all the technology in terms of aluminum engine, spruce propellers, spruce structural members, metal fitting. That all comes together in the system of the airplane. After those flights, a big wind comes up and tumbles and is demolished. They claim success, go they pack it up and go back to dayton where they are from. They sent a telegram to their father announcing their success. Its a quiet way of saying the aerial age has emerged. By 1905, an approved flier
