Tests carried out on a short static probe at supersonic speeds between Mach numbers of 1.1 and 2.5 are described. The probe consists of a 50° included angle cone-cylinder having sensing holes 0.98 calibres aft 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 ...
In simple harmonic oscillation of the helicopter with hinged blades, the tip-path plane is tilted with respect to the shaft in the plane of oscillation and in the plane perpendicular to it. The angles of tilt can be expressed ...
The methods of classical aerofoil theory are used to derive a general theory for wings of any given plan form. Accordingly, the general downwash equation is split into two parts : one, the effective incidence, being due ...
This note gives a convenient method of obtaining CD from a pitot-static traverse in an aerofoil wake, using Jones' equation as modified by Lock, Hilton and Goldstein for compressible flow. Charts are provided from which ...
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 ...
