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 ...
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 ...
