Hendy Boat Automatic Control Circuit

摘要

In order to obtain automatic control for the hydrofoil boat, it is necessary to obtain information as to the position of the hydrofoil struts in the water, and to utilize this information to control the angle of attack of the various hydrofoils to maintain stable and level flight. In the Hendy boat, the information as to strut position is obtained from a set of eight pitot tubes on each forward strut. Each individual pitot connects to a bellows operated contact such that each submerged pitot closes its associated bellows contact. This information is then utilized in automatic circuits to stabilize the boat.
