The classical theory of wind-tunnel interference is extended to cover interference on the effectiveness of a full-span jet flap issuing from the trailing edge of a high aspect ratio unswept wing. It is shown that, for small ...
Some interference effects between fuselage and wing are studied for two classes of configurations. The fuselage is an infinite cylinder of circular cross section with the axis parallel to the main stream. The wings have ...
A method is developed of calculating the performance of a pair of contra-rotating airscrews, closely analogous to that described in R. & M. 2035 a for a single airscrew. The assumptions made are considered to be theoretically ...
V-g records have been obtained during the past year on Hoverfly I helicopters. Some data have also been obtained on a Hoverfly II and a Sikorsky S.51. The V-g records on these aircraft were obtained mainly during test ...
The degree of cooling that might be achieved in gas-turbine blades with simple internal air-cooling is surveyed with a view to pin-pointing the essential requirements for effective cooling with small quantities of cooling ...
The phenomenon known as 'air resonance', peculiar to helicopters with hingeless rotors, has been analysed and presented in as simple a manner as possible. In the air resonance case the 'body mode' with frequency close to ...
In continuation of the tests reported in R. & M. 2463, an investigation was made into the hydrodynamic qualities of a small flying boat (Saro 37) with a 1 : 20 double curvature fairing over the main step. As before, the ...
