In R. & M. 1838 calculations of profile drag were made based on wing sections of conventional design, and were later extended in an Addendum to "low-drag" wing sections with convex trailing edges. Further calculations were ...
A brief survey is given of existing semi-experimental methods for the determination of two-dimensional aerodynamic derivatives for unsteady motion of a wing-aileron system (and, in particular, for aerodynamically balanced ...
The occasional complete or partial failures of "X" type parachute equipment are, so far as is known, always associated with one or more of the three following faults:- 1. Somersaulting of the man. 2. Twisted rigging lines. ...
A series of static tests ccnducted to establish an efficient form of flexible skirt for a peripheral Jet type of hovercraft is reported. The importance of designing the peripheral Jet system in conjunction with the skirt ...
The calculation of test factors is reviewed. The distribution, of the population from which the test sample is taken is assumed to be Gaussian. Three cases are discussed, in which (i) there is no prior knowledge of the ...
Some minor developments ill the technique of Thwaites' Numerical Method of Aerofoil Design I are described. In particular, the process of obtaining the camber-line ordinates from the Goldstein Approximation I velocity ...
On reading Dr. Hislop's paper I on experiments on a Hoverfly I aircraft which reproduces the 'characteristic' curve of an airscrew as given in R. & M. 1026, and on re-reading the latter report and R. & M. 1014 after an ...
G. I. Taylor in an Appendix to R. & M. 989 (1924) suggested that, in the two-dimensional flow of a real fluid, the circulations in all circuits enclosing the aerofoil and cutting the streamlines in the wake at right-angles ...
A criterion is given for the convergence of numerical solutions of the Navier-Stokes equations in two dimensions under steady conditions. The criterion applies to all cases, of steady viscous flow in two dimensions and ...
