Bernoulli’s Principle A Swiss scientist who was named Daniel Bernoulli in the 18th century discovered the Bernoulli’s Principle. Bernoulli (2009) stated that when the velocity of a gas or a liquid increases the pressure of the fluid would then decrease. This can be applied to many things, such as a plane or bird. Basically anything that uses wings to fly uses the Bernoulli’s Principle. Both birds and planes take an advantage of the Bernoulli the Bernoulli’s Principle. Flight (n.d.)[online] states that airplanes and birds have an airfoil shape. They have this shape in each of their wings and they are used to create lift. An airfoil shape has a certain shape that splits the air at the front part of the wing and it joins …show more content…

Lift always require an airfoil. An airfoil uses the Bernoilli’s Principle. That is only part of what you need for lift. You also need an angle of attack. This the angle that is used for your flight. Different angles gives you different results. Some angle can give you lots of lift, but lots of drag, or an angle can give you almost no drag, but little lift. Lift and drag all depends on the shape of the wing, the speed, and the angle of attack. Most planes start out with an angle that has the forward edge that is raised, so it has a lot of lift, and has a good lift to drag ratio. Then it would probably have an angle that gives you less drag and no lift so it could fly and get to the location faster. Weight is another important force of the plane. It basically acts like the opposite of lift. Without weight, it would be hard to come back down to the ground. Airplane designers normally try to make the airplane as light as they can, so the plane can fly faster, and so lift could be created easier and with less drag. Britannica (2014) says that pilots must control the total weight of the plane at all times. This weight includes the passenger, fuel, baggages, etc. Distributing the weight of the plane is as important as the weight of the plane in
