DOWNLOAD EBOOKThe use of baffles for directing the air around the cylinders with closely spaced fins proved very effective in increasing the over-all heat-transfer coefficient provided that the spacing was not appreciably less than that for maximum heat transfer.

DOWNLOAD EBOOKAs part of the wing-fuselage interferences investigation in progress in the N.A.C.A. variable-density wind tunnel, a method of eliminating the interference burble associated with critical midwing combinations was investigated. The interference burble of the critical midewing combination was shown to respond to modifications at the nose of the juncture and to be entirely suppressed with little or no adverse effect on the high-speed drag by special leading-edge fillets.

DOWNLOAD EBOOKResults are presented on drag tests of six bodies of revolution with systematically varying shapes and with a fineness ratio of 5. The formes were derived from source-sink distributions, and formulas are presented for the calculation of the pressure distributions of the forms. The tests were made in the N.A.C.A. variable-density tunnel over a range of values of Reynolds number from about 1,500,000 to 25,000,000. The results show that the bodies with the sharper noses and tails have the lowest drag coefficients are based on the two-thirds power of the volume. The data show the most important single characteristic of the body form to be the tail angle, which must be fine to obtain low drag.
