The method to be described here is attributed to the Russian investigator V. G. Galerkin, whose original papers are inaccessible to the present writer. His knowledge of the method is derived from a description given in a ...

The design of a turbine stage is considered on the basis of free vortex flow from the nozzles and blades and some of the factors which limit the design of an efficient turbine stage are discussed. As the flow conditions ...

The present report on the performance of a gyro plane contains the first really satisfactory set of full scale data to be obtained in this country, and affords a valuable means of checking a body of theoretical investigation ...

Summary. A study of steady lift interference effects in wind tunnels with several different wall conditions has been carried out using a three-dimensional resistance network. The methods by which the various boundary ...

An autogyro obtains remarkably high lift forces from a system of freely rotating blades and it is important to develop a theory which will explain the behaviour of an autogyro and will provide a method of estimating the ...

The flow of air past an infinite shell is considered. In its undisturbed state the shell is a circular cylinder. A portion of the shell between two normal cross-sections is flexible, the rest of the shell being rigid and ...

The present report gives a short account of a generalised type of Jankowski aerofoil which avoids the difficulty of extreme thinness near the trailing edge associated with the ordinary Jankowski aerofoils. Calculations ...
