Summary:

The results of tests made to determine the performance of a DePalma Roots-type supercharger are presented. The performance of the DePalma supercharger with atmospheric pressure at the discharge was compared withthat of a hypothetical N.A.C.A. Roots-type supercharger of the same displacement. The tests were conducted at speeds from 1,000 to 6,000 r.p.m. and at pressure differences fro 0 to 15 inches of mercury. The variation in clearance was determined for the DePalma supercharger at a speed of 2,000 r.p.m. and for the N.A.C.A. supercharger at speeds from 500 to 3,000 r.p.m. withthe pressure differences for each supercharger varying from 0 to 15 inches of mercury.
