A method, alternative to that in common use at present, of calculating the response quantities in pull-out manoeuvres relevant to important cases of loads and stresses in aeroplane structures, is presented. The method, ...
A flat plate containing a circular hole is subjected to arbitrary bi-axial stresses at infinity; adajcent to the hole and bonded symmetrically to both sides of the plate are cylindrically wound fibre composite annular ...
This note shows how the Hill Aero-isoclinic Principle works out in practice for a swept wing, fixed at the root and having straight flexural and inertia axes. The conditions assumed are readily represented in a wind-tunnel ...
A piloted flight simulator study of the low speed handling of the BAC 221 slender-wing research aircraft was performed for validation of the simulation of slender-wing supersonic transport aircraft. The lateral representation ...
Summary. This Report describes a fixed-base simulator investigation of the rolling requirements for two types of aircraft on the landing approach. A small trainer/strike aircraft, and a large transport aircraft are simulated, ...
The paper gives a theory of vortex flow in turbo-machines in which the basic assumption is made that the axial-velocity profiles always belong to a family governed by a single parameter, λ. This parameter is a measure of ...
To investigate the basic aerodynamic characteristics of jet-flap aircraft, six-component force and moment measurements have been made on jet-flap complete models in the R.A.E. No. 2 11½ ft x 8½ ft low speed wind tunnel. ...
The effect of a spawise surface corrugation on the position of transition from laminar to turbulent flow in the boundary layer of an aerofoil depends on the local disturbances caused by the corrugation and on the stability ...
The report, which has been written as a preliminary to a later account of similar work in lifting-plane theory, describes how wing loading problems involving discontinuities are solved by lifting-line theory. The four ...
The report describes in detail the methods by which the principles of vortex-lattice theory, introduced in a previous report, R. & M. 1910, are applied to the calculation of the aerodynamic loading of wings by lifting-plane ...
The laminar boundary-layer equation, for a linearly retarded velocity in the main stream, U = 1 - 1/8x in reduced variables, has been solved numerically by working in finite intervals in x, with a correction for the finite ...
Using actuator-disc theory, simplified methods are given for the solution of the direct problem of the incompressible flow of air through an axial-flow turbo-machine. Calculations based on these methods are compared with ...
After the publication of a report (R. & M. 2631) on the derivation of airworthiness performance climb standards, various subsidiary points raised in the course of discussions were examined. Some of these have been collected ...
An extension of slender-wing theory, introduced by Adams and Sears, has been applied to some problems concerned with the properties of slender, lifting, wings with curved leading edges at supersonic speeds. Two particular ...
Some general solutions of the linearised equations of supersonic flow, in terms of Lamé functions, were obtained by G. M. Roper, using the methods of Robinson and Squire. The results were applied to calculate : (a) the ...
This Report describes an analysis of air resonance in the hover, and the solutions obtained for a helicopter with non-articulated blades. It is shown that stability in air resonance depends critically on blade structural ...
Some comprehensive calculations of the flow conditions resulting from the intersection of a weak shock wave with a strong shock are presented and discussed, for a range of upstream Mach numbers between 1.4 and 2.8. Such ...
Summary. The rotation and flare-up phases of the take-off of a slender-wing supersonic transport aircraft are studied by calculating the time histories of speed, height, etc. when the pitch-attitude time history is specified. ...
Apart from some earlier experimental work by Henderson and Swalley, there does not appear to be available in the literature an analysis of the effects of small amounts of air contamination on the flow of helium in a ...
The convergence of numerical solutions of the Navier-Stokes equations for steady two-dimensional flow is examined and convergence criteria for both ψ and ζ are obtained for a rectangular mesh. The criterion for ψ is shown ...
