Increase in the maximum lift of an airplane wing due to a sudden increase in its effective angle of attack resulting from a gust
This is a 1932 NACA technical memorandum from the NASA Technical Reports Server, a government aeronautical research report on how a sudden gust raises an airplane wing's maximum lift, written for aerodynamics engineers and aircraft researchers. Its pictures are plain line graphs of fuselage acceleration and a corrective factor, a schematic of a wind-tunnel test apparatus, and grainy photographs of the rig, with no decorative styling a designer would borrow beyond the diagram's clean technical linework and the graph's grid structure.
