Stability and Maneuverability of the Airplanes
Maneuverability (its control) is ensured by the movements of moving parts of the plane making it possible to change its altitude, speed and direction.
Its stability is its property to be maintained at its altitude and to resist a displacement (due to a gust of wind for example) and in the event of perturbation to develop a force restoring the initial flying conditions. Until now we only considered the case of the airplane in cruising flight at constant speed and altitude. In this case we saw that the plane is subjected to 4 balanced forces (Lift-Weight, Thrust-Drag) applied in its center of gravity.

In addition to its displacement in horizontal direction, it is possible to consider side movements (rare for the planes) and rotation

It remains to induce the idea of stability. One generally speaks about two types of concepts: static stability and dynamic stability. By definition, the plane is balanced (one also says trimmed) in flight when the resultants of the forces and the couples around the center of gravity are null. A modification of one of the parameters of flight caused either by an atmospheric disturbance (wind, turbulence), or by an action on the controls, modifies these forces and moments temporarily. If their resultants tend to bring back the apparatus towards a position of balance, the aerodyne is regarded as statically stable. If not, it is statically unstable. It is important to note that this definition implies a tendency. One makes also the distinction between stability with free controls or controls blocked, according to whether the controls can move freely or that they are maintained in a fixed position during the movement which follows the disturbance. Before takeoff, the pilot will have to adjust various controls to ensure this stability according to the load of the airplane. (Patricia,
Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.
The book Flight written by Sherman Alexie is about a 15 year old part Native American
During World War II (WW2) the aeroplane proved to be the military’s greatest asset. It was dominant as it was versatile. Unlike the tank, boat or even the foot soldier the planes can serve in all areas of one countries military, land, sea and of course the air. They could fight where ever needed. Not only did they attack in dog fights or bombing raids they could go for a surveillance or reconnaissance to assist their forces. They destroyed many enemies industrial plants and provided many ground combat support.

They found that birds tilted their wings for balance and control, and tried to simulate this, developing a concept called “wing warping.” When they added a moveable rudder, the Wright brothers found they had the formula-on December 17, 1903, they succeeded in flying the first controlled flight of a power-driven airplane. Wilbur flew their plane for 59 seconds, at 852 feet, a crazy
Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.
...lity. When I research the definition of stability it stated: the strength to stand or endure. Therefore stability is something all organizations should value.
Flight is one of the most important achievements of mankind. We owe this achievement to the invention of the airfoil and understanding the physics that allow it to lift enormous weights into the sky.
The plane was not only used to spy on enemies but also to ambush them, machine guns could be attached to the planes and later used to shoot soldiers from the opposing sides. Inventors realized that if they could put machine guns on a plane, they could also bring bombs up there to surprise their enemies. We soon learned the biggest downfall from using flight as a weapon was sometimes innocent civilians would get killed by either machine guns or
...e in any one of these forces leads to a change in the others” (139). A pilot can use many different controls and means of propulsion to change and manipulate the balance of these forces. By doing this the pilot is able to change their speed and change their direction. The Physics of Flight are truly unbelievable occurrences that create amazing effects. Without the concept of flight we would live in a totally different world.
Paper Airplanes, flight at its simplest for humans. As kids, we learned how to build paper airplanes and send them soaring into the sky. We didn't stop to think about why the airplanes where able to fly after the initial thrust we gave them or how they were able to glide for so long afterwards. Ignorance was bliss then, but now we strive to understand how things work. Looking back to the childhood past time of flying paper airplanes, I will try to explain some of the parts that make paper airplanes fly.
Good stability and handling is achieved with a combination of suspension, steering, acceleration, brakes and weight distribution.
Aircraft are one of the biggest areas of advancement in the past. Military aircraft have become more sophisticated in variety, effectiveness, and maneuverability techniques in recent years. After it was found that aircraft could be very useful in war, they started to become a necessity of war. After World War 2, technological advances in aircraft began. The advances include stealth, targeting, maneuverability, etc.
...eding and locomotion. (flight allows dispersal almost world wide with time). Insects possess all types of legs for running, grabbing, digging, crawling, and clinging etc. They also possess wings. The ability to fly allows insects to disperse from a crowded and deteriorating habitat when necessary. For example, in Africa, populations of up to a billion locusts migrate annually from unsuitable dry areas to greener areas where rains are falling. In North America, Monarch butterflies will migrate to Mexico and coastal California to avoid harsh Canadian winters. Locally, ladybird beetles migrate to mountain tops during winter and summer.
