Hummingbirds in Flight



Hummingbirds are fascinating birds that are always fun to watch. These birds are able to
hover in mid-air, dart from side to side, go straight up or down, or even backwards. They
can out-fly and out-maneuver birds hundreds of times their size. There are many factors
that contribute to the hummingbirds' ability to fly so easily through the air.


A hummingbird's wings are shaped so that they are slightly rounded on the top. Bernoulli's
Principle explains why this helps the bird to fly. The air passing over the top of the
wing must travel further than the air going under the wing. As the hummingbird moves
forward, the velocity of the fluid increases over the wing and the pressure above the wing
is reduced. The higher pressure under the hummingbird's wing provides lift for the bird.


Hummingbirds have unusually strong muscles that enable them to raise and lower their wings
with great power. As the Hummingbirds thrust their wings up and down, they fly into the
air with amazing agility and speed. The sleek outline of the bird and smooth feathers

  • Accidents
    Accidents Aircraft Investigation Each mishap has their own characteristics and there is no substitute for good old-fashioned common sense and initiative. Each wrecked aircraft has its own story to tell if properly investigated. However Air Force guidelines are quick to point out that investigators in their eagerness seek out the causes, often ignore safe investigation practices and common safety precautions. Air Force Investigators are maybe in even more difficult position due to the hazards th

    History of the Aircraft Propeller History of the Propeller The aircraft propeller looks like a simple mechanism to the uneducated individual. To the educated, an aircraft propeller represents the highest sophistication in aerodynamics, mechanical engineering and structural design. This report will touch on the history of the propeller, from early pioneers/experiments, advancement during/after the war, all the way up to current applications of the propeller. The creation of the propeller can be t

    Airplanes in the 1920s Airplanes in the 1920s The 1920s were a time of changes in many areas of the American lifestyle. Examples include the changing roles of women, the African American struggle for equality, the changing sound of music, new forms of literature, growth of cities, and the development of airplanes and their uses. Major aircraft development started during World War I because America was striving to be stronger than any other country. War brought about the development of fighter an

    battle of britain In May 1940 after the fall of France, Hitler firmly believed that Britain, cut off from mainland Europe after the retreat from Dunkirk, would be ready to sue for peace if given enough time and incentive. He deduced that with Britain out of the war, America would come to terms with the new order as it could hope to gain no foothold in Europe without paying a terrible price. This would enable Germany to concentrate on what had always been considered the main threat, Russia. By 19

    History of Flight "A bird is an instrument working according to mathematical law... which it is within the capacity of man to reproduce." -Leonardo da Vinci The Wright Brothers may have invented the first airplane, made the first successful flight, and gone down in history as aviation pioneers, but the theory of flight goes back far before those boys were born. As early as the 16th century, Leonardo da Vinci had drawn things resembling a helicopter. Without knowing about aerodynamics, attempts w

This intellectual cultural awaking influenced European thinking by a concept of humanism, which emphasized the worth of an individual (Aston 12). Th

  • Flight
    Flight Research: Airplanes are an efficient way of traveling to far places. Airplanes are amazing if you know what and how the air keeps the plane airborne. There are three components of flight: aerodynamics, the Bernoulli principal and supersonic flight. Some other things about flight are the four forces, lift, drag, weight, and thrust. One of the basic things you need to know about airplanes is that the places where the plane can balance on one point called the center of gravity. The tail on t

    physics The use of aerodynamic forces by the expert golfer was demonstrated to me once by a drive off the tee by a well-known professional, Arnold Palmer. I stood directly behind him so that I could have the best view of the flight of the ball. Instead of the ball going on the path I had expected, it climbed in a nearly straight line for about 3 s and only then began to fall. Recall that Newton\'s First Law states that a body continues in a straight line at constant speed unless a force acts on

    The Physics of a golf Ball The physics of a golf ball The first written reference of golf was in 1457. Golf balls have had extraordinary changes since that time; theyve gone from leather pouches to dried gum to todays dimpled balls. These dimples help decrease the drag and increase the lift. Different forces are applied to the golf ball when struck by the club. Golf clubs have grooves to create backspin. And then there are different variables that affect how a golf ball will travel, these inc
