Book Synopsis Fuselage-drag Tests in the Variable-density Wind Tunnel by : Ira H. A. Abbott
Download or read book Fuselage-drag Tests in the Variable-density Wind Tunnel written by Ira H. A. Abbott and published by . This book was released on 1937 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results 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.

Book Synopsis Interference of Wing and Fuselage from Tests of 17 Combinations in the N.A.C.A. Variable-density Tunnel Combinations with Special Junctures by : Albert Sherman
Download or read book Interference of Wing and Fuselage from Tests of 17 Combinations in the N.A.C.A. Variable-density Tunnel Combinations with Special Junctures written by Albert Sherman and published by . This book was released on 1938 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: As 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.

Available in PDF, EPUB and Kindle. Book excerpt: The conclusions are that approximately the same drag coefficient is obtained at a given value of the Reynolds number irrespective of what combination of the variables is used to obtain the value of the Reynolds number and that the turbulence of the air stream at the test section, as measured by the critical Reynolds number of a sphere, is less for the new tunnel than for the old one.

Book Synopsis Hydrodynamic and Aerodynamic Tests of Models of Flying-boat Hulls Designed for Low Aerodynamic Drag by : Starr Truscott
Download or read book Hydrodynamic and Aerodynamic Tests of Models of Flying-boat Hulls Designed for Low Aerodynamic Drag written by Starr Truscott and published by . This book was released on 1938 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: N.A.C.A. models 74, 74-A, and 75 were tested in the N.A.C.A. tank to determine their hydrodynamic properties and in the N.A.C.A. 20-foot wind tunnel to determine their aerodynamic properties. The forms of these models were derived from that of a solid of revolution having a lowe air drag, and the departures from the form of this low-drag body were the minimum considered to give satisfactory take-off performance. Model 74 has a rounded bottom with flared chines, a transverse step wit ha small fairing aft of it, and a pointed afterbody. Model 74-A has the same forme except for the removal of the fairing aft of the step. Model 75 has a pointed step and a horizontal afterbody derived from the form of the N.A.C.A. model 35 series.
