As a result of one of the most significant inventions of the 20th century, the long time dream of steered flying was finally made plausible by the aeroplane. With the dream of a flying machine being in fashion, many inventors designed flying-machines of they’re own, many never being able to reach an airborne state. Inspired by such innovations in they’re youth; the American Wright brothers made aeronautical history on December 17th, 1903, by flying the first airplane of they’re own design for a 12 second sustained flight covering 120 feet. Equipped with a steering system, the aeroplane without a doubt surpasses hot air balloons and gliders with its ability to be controlled and directed. In 1909, after the Wright brothers reached they’re record flight of 3 days, 10 hours and 24 minutes, the military took interest in the use of the aeroplane, soon having the Wright brothers signing a contract to develop a design for military use.
They are, thrust, the forward motion or speed of the paper airplane, for our paper airplanes this is provided by your throwing the plane forward. Second is drag, which is the resistance of the aircraft against the wind. Third is gravity, the force that pulls down all things on the Earth. To alleviate this force an object needs to become light in weight. Last is lift, where the push of the wind under the wing is greater than the push on top of the wings.
Initially, gunpowder made several changes through history, starting with making the state of warfare completely different. Militaries started using gunpowder as a key component for their weapons. Starting with using it as a propellant for unguided rockets and to shoot the cannon. The Chinese were the first to come across gunpowder therefore they had hands on gunpowder which enhanced their weapons greatly compared to others (Gunpowder.c-1). The Chinese’s discovery of gunpowder gave the Chinese a great advantage, going into any type of war, and after awhile they were ahead of everyone else in warfare.
Lindbergh (1927) says he replaced the weight of the navigator with something called an inductor compass. This was based on the relation between the earth’s magnetic field and the magnetic field generated in the airplane. He claims “This inductor compass was so accurate that [he] really needed no other guide” (Lindbergh, 1927, p.515). The surprising speed of his plane was another reason why Lindbergh reached Paris with such ease. In the New York Times it talks about out of three pilots that attempted to keep up with him from takeoff, only one was successful.
THE DESIGN WAS RELATIVELY THIN AT THE LEADING EDGE AND PROGRESSIVELY WIDENED TO A POINT OF GREATEST THICKNESS AS FAR AFT AS POSSIBLE. THE THEORY IN USING AN AIRFOIL OF THIS DESIGN WAS TO MAINTAIN THE ADHESION OF THE BOUNDARY LAYERS OF AIRFLOW WHICH ARE PRESENT IN FLIGHT AS FAR AFT OF THE LEADING EDGE AS POSSIBLE. ON NORMAL AIRFOILS THE BOUNDARY LAYER WOULD BE INTERRUPTED AT HIGH SPEEDS AND THE RESULTANT BREAK WOULD CAUSE A TURBULENT FLOW OVER THE REMAINDER OF THE FOIL. THIS TURBULENCE WOULD BE REALIZED AS DRAG UP THE POINT OF MAXIMUM SPEED AT WHICH TIME THE CONTROL SURFACES AND AIRCRAFT FLYING CHARACTERISTICS WOULD BE AFFECTED. THE FORMATION OF THE BOUNDARY LAYER IS A PROCESS OF LAYERS OF AIR FORMED ONE NEXT TO THE OTHER, IE; THE TERM LAMINAR IS DERIVED FROM THE LAMINATION PRINCIPLE
Ancient Chinese Inventions Strayer University HUM 111 July 16, 2013 Dr. Caren Stayer The ancient Chinese culture can be credited for several important inventions. China has played a significant part in many famous inventions and contributions that has had a major role to play in our lives. Many of the inventions were invented as far back as c. 1600 B.C.-A.D. 265 (ancienthistory.about.com). The lists of inventions from ancient China are still used in modern day society. Some of the inventions are as follows: tea, gunpowder, a compass, chopsticks, bristle toothbrush, silk fiber, paper and printing, publishing, a seismograph (an earthquake detector), porcelain, acupuncture, lacquer, the wheel barrel, the abacius (calculator) and toilet paper.
Having the Right Stuff: A Definition In Tom Wolfe’s The Right Stuff the author opens his novel by beginning with test pilots performing their day-to-day dangerous job. The over all point that he makes in the first chapter is exactly how deadly the job really is. He makes this point by dramatically describing to the readers death after death of various pilots, detailing their specific accidents. Using the point of view of what the wives went through made his point even that more emotional. Wolfe than continues his story by describing the dangerous job of being an astronaut in the early stages of the space race.
Both countries spent billions of dollars on their space programs, because they believed that with controlling space they could have a more powerful country (Breuer 27). When the Soviet Union launched Sputnik and it became the first satellite in space, people of the United States and the world were scared of what the Soviets were going to do with this (Breuer 78-79). The Soviets continued to make major advances in the space race. In 1957, the Soviet Union launched Sputnik II, which carried a dog into space, and in 1961 the Soviets had the first man in space, Yuri Gagarin (Timeline of Space Explorations 1). In 1958, The National Aeronautics and Space Administration (NASA) was created (Timeline of Space Exploration 1).
The importance of these days will be explained in detail as you read along. Design Day (Day 1) During this day we set our minds to work to find a great contraption to save our egg from destruction. We were to create 3 prototypes by applying our knowledge of forces, fluid friction and Newton’s law for a successful experiment. Our first thought prototype consisted of an egg with a parachute. The parachute which was to be created with a cut out piece of a garbage bag, was to create an increase in air resistance.
People from the past have also improved these inventions. The Wright Brothers in 1903 invented the first airplane. On December 17 it took flight for twelve seconds. Their goal was to make a machine that could use its own power to ascend and descend. This invention has impacted people in many ways.
