This paper presents a computer aided procedure for the design of laminar proportional fluid amplifiers and gain blocks. The procedure is based upon a fundamental analysis of the flow regimes in an amplifier. With the aid of a computer, amplifier static and dynamic characteristics, required in control system design, may be determined as a function of geometry and fluid properties. The procedure is illustrated and evaluated by comparison of predicted design and experimentally measured performance. The procedure has been applied to individual elements designed by three different organizations, multistage gain blocks, and laminar jet rate sensor preamplifiers. The results of the procedure are shown to be quite accurate over a wide range of amplifier geometries (eleven different amplifiers with aspect ratio from 0.25 to 3 – a range of 12 to 1 – and nozzle sizes from 0.5 to 10 mm) and operating fluids (both air and oil). Experimental measurements were within 10 percent of the design predictions for amplifier gains, operating resistances, and bandwidth for all examples investigated.

A new computational geometry for the blades and flow passages of centrifugal compressors is described and examples of its use in the design of industrial compressors are given. The method makes use of Bernstein-Bezier polynomial patches to define the geometrical shape of the flow channels. This has the following main advantages: the surfaces are defined by analytic functions which allow systematic and controlled variation of the shape and give continuous derivatives up to any required order: and the parametric form of the equations allows the blade and channel coordinates to be very simply obtained at any number of points and in any suitable distribution for use in subsequent aerodynamic and stress calculations and for manufacture. The method is particularly suitable for incorporation into a computer-aided design procedure.
