Four physical forces , which are main elements of flying!
...... states that within a stream of fluid, pressure decreases as the speed of flow increases, and similarly pressure increases as speed of flow decreases.
What is main object using of flaps?
As with all applications of the Bernoulli's principle, we shall assume that the flow of air around the aerofoil is:
Everything moving through the air (including airplanes, rockets, and birds) is affected by ……
..... is the point at which the aircraft would balance were it possible to suspend it at that point.
..... are used in pairs to control the aircraft in roll, which normally results in a change in flight path due to the tilting of the lift vector.
..... are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing.
...... used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane.
In 1726, ..... became one of the first aerodynamicists in the modern sense when he developed a theory of air resistance, which was later verified for low flow speeds.
