Experimental data are presented for the development of compressible turbulent boundary layers moving from a solid onto a transpired surface, and vice versa. The data were obtained at free stream Mach numbers of 1.8 and 3.6 ...
Results are given of compression tests made on 56 Dural-Celluboard Sandwich Panels with Birch Spruce or Whitewood centres. These are compared with results from similar tests on Dural-Balsa sandwich and all-metal panels, ...
The routine testing of aircraft-type compressors--in the main, axial-flow, multi-stage compressors--requires a compromise between research accuracy and the practical considerations. This test code is the outcome of a survey ...
The singular double integrals which arise in the calculation of the components of perturbation velocity due to a swept wing with given thickness distribution by linearised theory, have been evaluated by a numerical method. ...
Johannesen has discussed a Rayleigh-line method for the analysis of vibrational relaxation regions in shock waves. In this method the flow of the real gas in the relaxation region is treated as the flow of an ideal gas ...
The concept of complex stiffness in problems of oscillations with viscous, or structural (hysteretic) damping is often used in a wrong way, leading to erroneous solutions. It is shown in the Paper that correct expressions ...
The stability of an annular air intake at a Mach number of 1.4 and with Reynolds numbers of about 1.5 x 10power6 is considered in detail and a method is described whereby the experimental results might be extrapolated for ...
The formation of a conical shock and a conical region of flow separation originating from the tip of a thin traversing tube was observed in a supersonic tunnel as a result of interaction of a strong shock with the boundary ...
