The aerodynamics of an airplane sometimes don't cooperate with the pilots desire to roll, and instead produce both yaw and roll. Contributing factors are aileron parasite drag, induced drag between the wings and changes in the roll rate itself;
Pilots, especially those in low-powered aircraft, must always know how much energy they have available to maintain flight.
Tubes, struts, and column buckling.
The discussion of lateral/directional stability continues with an examination of dihedral effect and the effect of roll;
Last month we took a look at the effects of span and aspect ratio. At this point on the design of the wing, we...
Design process-tail volume. By Barnaby Wainfan.
Last month we began our discussion of the structural layout of the wing with a look at externally braced wings. We now turn our...
Contrary to popular belief, the frontal area of an airplane is not the most important determinant of drag.
