Download or read book Tank Tests of a Family of Flying boat Hulls written by James M. Shoemaker and published by . This book was released on 1934 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents towing tests made in the N.A.C.A. tank of a parent form and five variations of a flying-boat hull. The beams of two of the dervied forms were made the same as that of the parent and the lengths changed by increasing and decreasing the spacing of stations. The lengths of two other of the derived forms were made the same as that of the parent while the beams were changed by increasing and decreasing the spacing of buttocks, all other widths being changed in proportion. The remaining derived form has the same length and beam as the parent, but the lines of the forebody were altered to give a planing bottom with no longitudinal curvature forward of the step.

This book was released on 1933 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: N.A.C.A. Model No. 11-A was designed as an improvement over N.A.C.A. Model No. 11, a complete test of which is described in N.A.C.A. Technical Note No. 464. In contrast with the longitudinal upward curvature in the planing bottom forward of the main step on Model No. 11, the planing bottom of Model No. 11-A was made as flat as practicable. Otherwise, the two models have very nearly the same form.

Download or read book Tank Tests to Determine the Effect of Varying Design Parameters of Planing tail Hulls written by John R. Dawson and published by . This book was released on 1946 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second part of a series of tests made in Langley tank no. 2 to determine the effect of varying design parameters of planing-tail hulls is presented. Results are given to show the effects on resistance characteristics of varying angle of afterbody keel, depth of step, and length of afterbody chine. The effect of varying the gross load is shown for one configuration. The resistance characteristics of planing-tail hulls are compared withthose of a conventional flying-boat hull. The forces on the forebody and afterbody of one configuration are compared with the forces on a conventional hull.

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.
