Process Variables in Direct Extrusion
Figure 15.4 Process variables in direct extrusion. The die angle, reduction in cross-section, extrusion speed, billet temperature, and lubrication all affect the extrusion pressure.
An airfoil or aerofoil is the shape of a wing, blade (of a propeller, rotor, or turbine),
or sail (as seen in cross-section).
An airfoil-shaped body moved through a fluid produces an aerodynamic force. The component of this force perpendicular to the direction of motion is called lift. The component parallel to the direction of motion is called drag. Subsonic flight airfoils have a character

1 Introduction
When designing an aircraft, it’s all about finding the optimal proportion of the weight of the vehicle and payload. It needs to be strong and stiff enough to withstand the exceptional circumstances in which it has to operate. Durability is an important factor. Also, if a part fails, it doesn’t necessarily result in failure of the whole aircraft.
The main sections of an aircra
