Abstract
THE development of the details of flying machines between 1908 and the present time is immediately obvious on a visit to the Aero Exhibition; but, quite apart from the higher standard of workmanship, it is also evident that scientific principles are governing the design of aeroplanes to a greater and greater extent. Almost without exception the designs show evidence of the general desire to keep the resistance of the machines as low as possible and so get increased lifting power and speed. It is not any longer necessary to consider the bare possibility of lift, as the shape of the wings is now so good as to give about 20 lb. of lift per horse-power, and engines available for aeroplanes can be obtained of horse-powers up to 160, weighing less than 3 lb. per horse-power; such an engine can then carry, roughly, 1½ tons, a weight greater than that of any existing aeroplane.
