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' ...
A method of estimating the airborne path during take-off is proposed, based on the assumption that the aircraft is rotated at a constant rate of pitch from the moment of lift-off to the point at which it attains a steady ...
Current design proposals for many swept-winged aircraft have large engines of high bypass ratio wih short fan cowls on short pylons under the wing, with the annular fan nozzle close to the wing leading edge. With such an ...
Secondary flow measurements have been made within the turbulent boundary layers at two streamwise cross-sections of a 180 degree curved channel. The results indicate substantial three-dimensionality on all four walls of ...
Details are given of some of the methods of solving the flutter equations which have been programmed in Mercury Autocode at the R.A.E. Included is a method of following the variation of critical speed with a linear variation ...
This paper is concerned with the classification of nonlinear vibration problems which occur in the field of aeronautics - excluding those problems which may be more suitably defined under the heading 'nonlinear problems ...
A semi-automatic data handling system has been constructed at the R.A.E. for use in wind tunnel and laboratory tests on aeroelastic models. The system can accept fifty inputs of static information and fifty oscillatory ...
A computer program in Extended Mercury Autocode (EMA) is described for the finite element analysis of plane stress problems in regions of arbitrary geometry, using constant strain triangular elements.
This Report considers theoretically and experimentally some of the problems associated with the flexure of two unequal cylindrical shells Joined by a conical frustum. Particular attention is given to the determination of ...
