An aircraft is a machine that is able to fly by gaining support from the air‚ or‚ in general‚ the atmosphere of a planet. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil‚[1] or in a few cases the downward thrust from jet engines. The human activity that surrounds aircraft is called aviation. Crewed aircraft are flown by an onboard pilot‚ but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft

This essay is a "how-to" essay that fully explains in detail how to make a paper airplane. It also give history of the paper airplane and instructions on how to put it into flight. PAPER AIRPLANE Since early in history‚ man has been fascinated with the sky and possibilities of flight. Improvements in flight‚ especially in the 20th century‚ have revolutionized the world. People can go around the world in less than a day‚ cross oceans in a matter of hours‚ even go from city to city in a fraction

The Physics behind Flying Airplanes There are several aspects involved in the dynamics of airplane and how they become airborne. This report will address the main physics involved and mathematic formulae that prove how airplanes get above the ground from a small fighter jet to a massive Boeing 747. The necessities involved in keeping there massive weights in the air and the extreme forces needed to land these airplanes and bring them to a halt will also be explored. Firstly‚ the formula F

The Wright Brothers; Inventors of the Airplane The incredible interest of Orville and Wilbur Wright in flying‚ was said to be initially sparked with their experience of a toy given to them by their father. The foot long toy “helicopter” was made out of paper‚ bamboo and cork with a rubber band to turn its rotor. The Wright brothers played continuously with their toy until it broke and after that they built one of their own. Wilbur Wright was born on April 16‚ 1867 in Millville‚ Indiana. He was

In the article “Why are Airplanes safe” the main idea is that out of all the transportation there is in the world‚ the safest is flying on a airplane. In the article the author Christine Negroni explains all the reasons why it is the most safe transportation because all the pilots are trained and the airplane is always checked for safety measures. Negroni supports her explanation by explaining all the details it takes just to be able to have one flight to be successful. The author explains

Bastille The Bastille was a form of government representation or a way to represent royal authority in the centre of Paris. Furthermore‚ the national day in France is on July 14 to recognize the Storming of the Bastille. To continue‚ the storming of the bastille occurred on one main reason. To begin with‚ in 1789 there was something called the 3 estates. The three estates was divided into Nobles‚ Clergy and the rest of the population. The rest of the population were forced to pay 100% of the taxes

The First Who Invented the Airplane Many people worked on various kinds of gliders and other planes over the years‚ so no one person invented the airplane. The Wright Brothers of Dayton‚ Ohio‚ are generally recognized as making the first powered aircraft flight (but see below). On December 17‚ 1903‚ the Wright Brothers launched the first successful air flight at Kitty Hawk‚ NC‚ flying over the location four times. Orville flew the first flight‚ Wilbur having encountered difficulties in his

Today I will be talking about paper airplanes and what type of paper airplane flies the farthest also which one stays aloft the longest. Some of the topics I plan to discuss involve aerodynamics‚ drag‚ shape‚ size‚ forces‚ and gravity. Drag is the force of flight that pushes an airplane opposite to the direction it is moving. The biggest types of drag are friction‚ when air rubs against the surface‚ and difference in air pressure. Think of a drag like swimming treading through the water you can’t
