Automatic rudder/fin control ; also refers to the idea that altering wing angles will exercise control over the course of the craft, without offering technique for it. IMPORTANT. Predecessor of wing warping. Wings have a good shape. mentions angling the wings rather like ailerons. GOOD design from 1897. Did he know Chanute's design?
Christine MacLeod, "Reluctant Entrepreneurs: Patents and State Patronage in New Technosciences, circa 1870–1930" (Isis 103(2), June 2012):
One patent that, in other circumstances, might have been foundational was Frederick W. Lanchester's for “Improvements in Aerial Machines” (no. 3608; 1897). Not only did it describe all the necessary elements of a fixed-wing powered airplane, but, exceptionally, it also distilled the theory that explained why such an aircraft would fly. It was listed in the first volume of the Aeronautical Journal; but it belied Baden-Powell's faith in patents as conduits of new knowledge, since in the following decade the society's members passed from ignorance of Lanchester's theoretical insights to incomprehension.
