d FLIGHT. FEBRUARY 17, 1938. curve of the upper wing is an " envelope ' curve, i.e., that at all angles of incidence it is outside the curve of the • lower wing. If that is done, the lower wing, or rather the wing of the lower component, will stall before that of the upper component. F"rom the lift curves of the two wings it is possible to plot a graph in which the lift of each wing is shown against speed. Here it should be explained that at small angles of incidence the lift is smaller, and it is necessary to fly at higher speed in order to get the lift. The curves on the preceding page bear no direct relationship to the actual Short-Mayo composite, as the two wing sections used as a basis for the calculations are quite different from those of the Maia and 'Mercury. One result is that they show a rather lower '' separa- tion speed " than that of the actual machines. On the left is a view inside Mercury, looking forward. The other two pictures show the cockpit of the Maia, and the indicating lights which show the trim and pull of the upper component at any given moment. (Photos. b>i Cullender's Cable Co.)
