The present paper makes use of and extends a paper by Munk in which simple dynamic concepts are used to prove that the lift-curve slope and thickness drag of supersonic airfoils or system of airfoils with supersonic edges are the same when the airfoil is flown in a reversed direction. This extension of Munk's work provides a proof that the thickness drag, lift-curve slope, damping in roll, and the damping-in-pitch parameter remain the same when any airfoil is reversed, in both subsonic and supersonic flow. The theorem applies to cases in which the trailing-edge velocities are finite; no restrictions are placed on plan form.

Reverse-flow theorems in aerodynamics are shown to be based on the same general concepts involved in many reciprocity theorems in the physical sciences. Reciprocal theorems for both steady and unsteady motion are found as a logical consequence of this approach. No restrictions on wing plan form or flight Mach number are made beyond those required in linearized compressible-flow analysis. A number of examples are listed, including general integral theorems for lifting, rolling, and pitching wings and for wings in nonuniform downwash fields. Correspondence is also established between the build-up of circulation with time of a wing starting impulsively from rest and the build-up of lift of the same wing moving in the reverse direction into a sharp-edged gust.

Six numerical examples are presented for steady, two-dimensional, compressible, nonviscous flow in centrifugal compressors with straight blades. A seventh example is presented for incompressible flow. The solutions also applye to radial-flow turbines with rotation and flow direction reversed. The effects of variations in following parameters were investigated: (1) flow rate, (2) impeller-tip speed, (3) variation of passage height with radius, and (4) number of blades. The numerical results are presented in plots of the streamlines, constant Mach number lines, and constant pressure-ratio lines. Correlation equations are developed whereby the flow conditions in any impeller with straight blades can be determined for all operating conditions.
