Design Content Description

An airplane is a device that almost does not work. As a vehicle, it is unique in that it has a minimum as well as a maximum speed, and every piece of the airplane can be regarded as weight critical – particularly the structure. Development and application of the primary airplane performance equations provides a vivid illustration of the design trades in the creation of an airplane.
