A fluid compressor of the pitot type includes a high speed, high stress rotary casing. The casing is formed from a pair of tapered discs spaced apart and mounted for rotation about an axis. The discs form the end walls of the casing. A side wall is connected between the opposed peripheral portions of the discs to enclose the casing and a stationary pitot tube. The side wall is formed from a pair of concentric rings connected by a plurality of beams. In one embodiment, the beams are C-shaped with an upper leg attached to the outer ring and a lower leg attached to the inner ring, the longitudinal axis of the beams being parallel to the axis of rotation. In an alternate embodiment, the rings are formed from the upper and lower legs of a plurality of I-shaped beams, the longitudinal axis of the beams being parallel to the axis of rotation.
