Abstract

635,784. Reducing surface friction. JABLONSKI, Z. S., and ROBERT, R. A. July 14, 1947, No. 18632. Convention date, July 19, 1946. [Class 4] The frictional resistance of a body moving relatively to a fluid is reduced by ionising the fluid particles in the boundary layer and increasing their kinetic energy by the effect of an electric field developed in the fluid in the vicinity of the body. As shown in Fig. 6, electrodes 30, 32 on the surface of the body are connected alternately to the positive and negative poles 33, 31 of a source of electric potential, or the electrodes may be connected to a source of alternating current. Fig. 8 shows an arrangement in which powdered material from a cavity 44 is discharged through slots 41, 42 over the electrodes 38, 39. To promote ionisation the plates on the surface of the body may be coated with radio-active material.
