Popular Features. New Releases. Mathematical Methods in Aerodynamics. Description The researchers in Aerodynamics know that there is not a unitary method of investigation in this field. The first mathematical model of the air- plane wing, the model meaning the integral equation governing the phe- nomenon, was proposed by L. Prandtl in The integral equation deduced by Prandtl, on the basis of some assumptions which will be specified in the sequeL furnishes the circulation C y see Chapter 6.
U sing the circulation, one calculates the lift and moment coefficients, which are very important in Aerodynamics.

The first hypothesis made by Prandtl consists in replacing the wing by a distribution of vortices on the plan-form D of the wing i. Since such a distribution leads to a potential flow in the exterior of D and the experiences show that downstream the flow has not this character, Prandtl introduces as a sup- plementary hypothesis another vortices distribution on the trace of the domain D in the uniform stream. The first kind of vortices are called tied vortices and the second kind of vortices are called free vortices.

The total lift produced by the airfoil is equal to the difference between the two pressures. Students will be able to calculate centrifugal from given information.

Centrifugal force plays an important part in every day activities. For example when riding a bicycle one must lean towards the center to get around a corner. Centrifugal force makes it necessary for a car to turn a corner at high speeds without turning over.
Centrifugal force can be studied by experimenting with a string and a ball. Demonstration a have a student whirl a ball attached to an elastic string around in a circle. To determine centrifugal force use; c. Materials: a elastic b balls of different weights. The term airfoil section refers to the shape of a cross section of a wing, and also to the outline of a lifting surface.
Experiments have shown that the shape of the airfoil can affect the performance of the plane. Step 1: Draw the datum line and vertical axis figure available in print form Step 2: Mark all sections as given in data.

Step 3: Mark the distance of the upper camber from the datum line. Step 4: At the first station, mark the distance of the upper camber above the datum line. Step 5: Mark off the other points, then connect with a smooth line.
