Concerning the Flow about Ring-shaped Cowlings of Finite Thickness
It is shown how one may obtain, in a simple manner, the forms of ring-shaped bodies from existing tables of functions according to the customary method of superposition of flow due to singularities and parallel flow. A number of examples of the forms and pressure distributions of annular source bodies with and without hub body are given and the inlet conditions of such ring-shaped cowlings are investigated. Furthermore, the annular bodies of finite length are indicated that correspond to Joukowsky profiles for the two-dimensional case. The examples are to give a basis for the design of a cross-sectional forms of ring-shaped cowlings and a survey of the flows to be expected.
Concerning the Flow about Ring-shaped Cowlings
The dependence of the maximum incremental velocities and air forces on a circular cowling on the mass flow and the angle of attack of the oblique flow is determined with the aid of pressure-distribution measurements. The particular cowling tested had been partially investigated in NACA TM 1327.
Progress in Aeronautical Sciences
Progress in Aeronautical Sciences, Volume 3 deals with topics in the field of aerodynamics. The book covers topics on aerodynamic design, propulsion systems, hypersonic flows laboratories, and gust research. The text is composed of four articles. The first article presents a review of the aspects of aerodynamic design of swept-winged aircraft. The second paper surveys the applications of ducted propellers. Critical reviews of experimental hypersonic facilities are provided in Chapter 3. The last paper focuses on the meteorological and aeronautical aspects of atmospheric turbulence. Aeronautical engineers, pilots, aviators, and students in the field of aerodynamic design will find this book invaluable.
Concerning the Flow about Ring-shaped Cowlings
The investigations carried out in a previous report (NACA TM 1325) concerning the flow about ring-shaped cowlings were extended by taking a circulation about the cowling into consideration. The present second report treats bodies of infinite length with approximately smooth entrance. The circulation was caused by distributing vortex rings of constant density over a stream surface extending to infinity. Furthermore, the influence of a hub body on such cowlings was dealt with. The examples treated are meant to give the designer a basis for his design.
