Future problems of soaring flight : report of 1932 Rhon soaring contest
A 1933 NASA technical report, drawn from the NTRS collection, on future problems of soaring flight as discussed at the 1932 Rhön soaring contest in Germany, written for glider researchers and pilots. The four pictures are technical charts: altitude-against-temperature diagrams of dry and damp adiabatic lapse rates with climbing-speed curves, a graph of glider flight durations by year, and a map of storm-front courses across central Germany, all in plain black line on white with hatched bands and labelled points that a designer could borrow as clean schematic diagram styling.
