This did not simply happen overnight. The brothers had been tinkering with the idea of flight off and on since childhood. They were mechanically inclined young men who were inspired by the efforts of others.

Types of aircraft

History of flight , development of heavier-than-air flying machines. Important landmarks and events along the way to the invention of the airplane include an understanding of the dynamic reaction of lifting surfaces or wings , building absolutely reliable engines that produced sufficient power to propel an airframe, and solving the problem of flight control in three dimensions. Once the Wright brothers demonstrated that the basic technical problems had been overcome at the start of the 20th century, military and civil aviation developed quickly. This article tells the story of the invention of the airplane and the development of civil aviation from piston-engine airplanes to jets. For a history of military aviation, see military aircraft ; for lighter-than-air flight, see airship.

History of Aviation

An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil , [2] or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes , helicopters , airships including blimps , gliders , paramotors and hot air balloons. The human activity that surrounds aircraft is called aviation. The science of aviation, including designing and building aircraft, is called aeronautics. Crewed aircraft are flown by an onboard pilot , but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers.

An aircraft that is required to keep out of the way of another aircraft must avoid passing over or under the other, or crossing ahead of it, unless passing well clear. An aircraft that has the right of way must maintain its heading and speed, but nothing in the rules shall relieve the pilot in command of an aircraft from the responsibility of taking such action as will best avert collision. When two aircraft are on converging headings at approximately the same height, the aircraft that has the other on its right must give way, except that CAR :. When two aircraft are approaching head-on or approximately so and there is danger of collision, each shall alter its heading to the right. An aircraft that is being overtaken has the right-of-way and the overtaking aircraft, whether climbing, descending, or in horizontal flight, shall keep out of the way of the other aircraft by altering its heading to the right, and no subsequent change in the relative positions of the two aircraft shall absolve the overtaking aircraft from this obligation until it is entirely past and clear.

Early flying machines include all forms of aircraft studied or constructed before the development of the modern aeroplane by The story of modern flight begins more than a century before the first successful manned aeroplane, and the earliest aircraft thousands of years before. Some ancient mythologies feature legends of men using flying devices. One of the earliest known is the Greek legend of Daedalus ; in Ovid 's version, Daedalus fastens feathers together with thread and wax to mimic the wings of a bird. Eventually some tried to build flying devices, such as birdlike wings, and to fly by jumping off a tower, hill, or cliff. During this early period physical issues of lift, stability, and control were not understood, and most attempts ended in serious injury or death. In the 1st century AD, Chinese Emperor Wang Mang recruited a specialist scout to be bound with bird feathers; he is claimed to have glided about meters.

The Road to the First Flight

Спускаясь по лестнице, она пыталась представить себе, какие еще неприятности могли ее ожидать. Ей предстояло узнать это совсем. ГЛАВА 2 На высоте тридцать тысяч футов, над застывшим внизу океаном, Дэвид Беккер грустно смотрел в крохотный овальный иллюминатор самолета Лирджет-60. Ему сказали, что бортовой телефон вышел из строя, поэтому позвонить Сьюзан не удастся. - Что я здесь делаю? - пробормотал .

 Мидж… я уже говорил… - Да или нет: мог в ТРАНСТЕКСТ проникнуть вирус. Джабба шумно вздохнул. - Нет, Мидж. Это абсолютно исключено. - Спасибо. Джабба выдавил из себя смешок и попытался обратить все в шутку. - Если только Стратмор не придумал что-то особенное и не обошел мои фильтры.

 На самом деле я его не продала, - сказала Росио.  - Хотела это сделать, но она совсем еще ребенок, да и денег у нее не. Вот я его и отдала. Но если бы знала, сколько вы мне за него предложите, то сохранила бы это кольцо для. - Почему вы ушли из парка? - спросил Беккер.  - Умер человек. Почему вы не дождались полицейских.

Rules for prevention of collision

 И что все это. - Не знаю. Все это выглядит довольно странно. - Думаешь, надо вернуть им отчет.

Войду, возьму его и тотчас выйду. Давай ключ. - Мидж… Она прекратила печатать и повернулась к. - Чед, список будет распечатан в течение тридцати секунд. Вот мои условия.

Сердечный приступ. Беккер безучастно кивнул: - Так мне сказали. Лейтенант вздохнул и сочувственно помотал головой. - Севильское солнце бывает безжалостным.

Early flying machines

Пока техники тщетно старались отключить электропитание, собравшиеся на подиуме пытались понять расшифрованный текст. Дэвид Беккер и два оперативных агента тоже пробовали сделать это, сидя в мини-автобусе в Севилье.

There are a number of ways to identify aircraft by type.

At last, we made a hang glider like plane with a straw frame and a balloon engine to make successful, we could made another successful flying machine.. It was First, I made a helicopter thing with a popsicle stick propeller, a paper clip box.
