The boundary layer flow over a cone inclined at a small angle to a supersonic stream, and over a type of caret (Maikapar, Nonweiler) surface, as generalised by Townend, is calculated by an implicit finite difference method. ...
Six methods for the approximate solution of the three-dimensional laminar boundary layer momentum integral equations are presented and oompared with three known exact solutions. These methods all involve the Pohlhausen ...
The streamwise velocity profile is established as the most suitable basic profile for the calculation of three-dimensional turbulent boundary layers. Measured streamwise profiles are compared with Thompson's two-dimensional ...
The discrete element displacement method is applied to the prediction of the natural frequencies of lateral vibration of rectangular plates which may be subjected to arbitrary systems of in-plane loading. Numerical results ...
Tests have been made to measure the movement of the wing tip vortices from a Hunter aircraft flying at 170 knots approximately 35 feet above a runway, in a variety of wind conditions. Measurements were limited to a maximum ...
This paper investigates the stability of finite-difference schemes, including boundary conditions, for solving the time-dependent Navier-Stokes equations. The different types of boundary condition whioh may occur are listed ...
The principle of elastic relaxation is considered as a technique for drawing polymers at high velocities. The theory is worked out and some tests are described in which skeins of low density polyethelene filaments have ...
This Paper is intended as an introduction to the study of fluid flow and heat transfer in rotating ducts, and to serve as a basis for discussion of this field of work. The interest in this subject results mainly from the ...
The results of an experimental investigation which studies the influence of rotationally induced buoyancy on heat transfer in a tube which rotates about an axis parallel to itself is presented. Data obtained with water and ...
The suggestion that the sonic bang may be alleviated by electrostatic means is examined and several objections to the idea are put forward. At the same time, some theoretical aspects of supersonic electrogasdynamics are ...
Early lifting structures and planforms With two straight sides and circular ends and with many lifting points in order to encompass road vehicles economically. Problems of load slinging and structural inflexibility, however, ...
Some calculations based on the performance of an ideal shock-tube are presented. These demonstrate the possibility of achieving a high test-section Reynolds number in a reflected-shock tunnel, employing nitrogen or air as ...
Some excerpts from a record of data obtained in an encounter with moderate turbulence during routine operations by a transport aircraft are analysed in order to assess the contribution to the cg normal accelerations from ...
This Paper should be read in conjunction with A.R.C.26912 (C.P. 866) The absolute values of the results obtained do not have a great significance. Their main interest lies in their relationship to those of C.P. 866. In ...
Four models of an aircraft configuration with a 55 degree swept wing were flown at Mach numbers between 0.9 end 1.4, at Reynolds numbers up to 10 million and lift coefficients between zero and 0.5. Measurements of the ...
An approximate analysis is given of a turbulent wall-jet beneath a stream moving at constant velocity. The results of this analysis are used to predict the drag of a cylindrical afterbody immersed in the jet from a front ...
Three methods of determining an unsteady interference parameter in slotted wind tunnels are described. In each case the governing equation for the flow in the wind tunnel is Laplace’s equation which is solved by a finite ...

A small number of jet aircraft in normal airline service are fitted with recorders which produce continuous trace records of airworthiness data for 14 parameters. Throughout the recording period the records have been ...
A method for the calculation of the section thickness distribution to produce a given symmetrical pressure distribution near the critical Mach number is presented. By linearisation about a known solution, obtained by Sells' ...
