Measurements have been made of the direct two-dimensional damping and stiffness derivatives for a 20 per cent aileron on an aerofoil with a 1541 section in incompressible flow. Corrections arising from the apparatus are ...
Measurements have been made of the direct tab derivatives and cross aileron-tab derivatives for a 1541 section two-dimensional aerofoil (N.P.L. 282) with a 20 per cent aileron and 4 per cent (approx.) tab. In addition some ...
An attempt has been made to determine whether a large contraction ratio and wire gauze screens in the maximum section would prevent unsteadiness of flow in the return circuit frcm affecting the flow in the working section.
Measurements have been made of the longitudinal characteristics of one plane and three cambered slender ogee wings at two subsonic and eight supersonic Mach numbers up to 2.8. The tests also included measurements of the ...
Part I of this report describes an experimental, cooled turbine, designed and built for research into problems associated with the operation of turbines at very high gas temperatures, in particular, the problem of turbine ...
A numerical method is given for calculating the lifting forces on oscillating wings of any plan-form. The principles and techniques of Multhopp's subsonic theory have been applied to the supersonic problem resulting in a ...
The incompressible flow past an aerofoil with a thin jet emerging from its lower surface somewhere near the trailing edge is considered. Based on unpublished work of Gates, Maskell and Spence, a simple method is described ...
