Abstract : A function control unit was designed as a component instrument of the Bureau of Ships analog computer (BUSAC). It is intended for use with the BUSAC curve follower, which produces a function representing cross sections of the ship's hull; the function control unit serves to modify and supplement this function in a known and controllable manner. For example, it can operate upon the input function to produce a waveform simulating static or dynamic conditions under various degrees of loading, heave, roll, or pitch. This report discusses the design and principle of operation of the instrument, which is known as the TMB Type 161-A Function Control Unit, and gives schematic circuit diagrams, adjustment procedures, and operating instructions.
