Test Reports of the Aeronautical Laboratory of the R. Istituto Superiore Di Ingegnegria of Turin*
Published online by Cambridge University Press: 28 July 2016
Summary
The present 2nd Series of the “Rendiconti sperimentali del Laboratorio di Aeronautica del Reale Istituto Superiore di Ingegneria di Torino” follows on the 1st Series published in April, 1934. It includes:—
(1) Description of a new six-forces balance.
(2) Statement and discussion of the results of the tests on :—
(a) a 600 mm. wind tunnel with open jet and return flow, with the object of deter- mining the influence on the steadiness and distribution of velocity of the stream in a cross-section of the jet of various details of design (dimensions of the cells of the honeycomb, cascades, etc.) and the diffusion of the portion of the airstream undisturbed by the air carried along by the jet owing to the effects of viscosity.
(b) on fifteen models of wings.
(c) on three motor car models.
(d) on an airscrew model mounted at various lateral angles to the relative asymptotic wind (airscrew in a side wind).
(e) on three models of tail plane in the presence of an airscrew.
The last-mentioned tests on tail planes are part of a series of tests still being carried out with the financial assistance of the Directorate of Research and Experiments of the Air Ministry at the suggestion of General Crocco, with the object of determining the influence of the working airscrew on the aerodynamic characteristics of tail surfaces.
