WE conclude in this issue the very exhaustive study of spinning contributed by Messrs. Irving and Stephens to that gold mine of scientific informationthe transactions of the Royal Aeronautical Society. Partly for reasons of space we have omitted a number of diagrams and a passage containing the...
SOME of the major problems under investigation by the National Advisory Committee for Aeronautics may be placed under the general heading of safety in flight. One of the most important of these problems is the study of spinning, both in the wind tunnel and in free flight. In the usual horizontal...
THE air flow in the slipstream of an airscrew is helical in nature. It follows, therefore, that there is a torque reaction on the whole aircraft which must be overcome by an equal and opposite moment produced by an asymmetrical distribution of air forces on the aeroplane as a whole. These torque...
APPARENTLY twobladed airscrews are acrodynamically more efficient in traction than multibladed varieties, and, moreover, are easier to manufacture. Furthermore, they are simpler to transport. There were, however, decided drawbacks peculiar to the twobladed airscrew. The more important of these...
THE engine section of the De Havilland Company's works at Stag Lane, Edgware, forms a branch which is quite a separate unit, complete in itself, from the aircraft factory, the only connection being the general offices which are common to both.
THE Edward G. Budd Manufacturing Co. has completed successful test flights with a new type of aircraft, designed by the engineering staff of the American Aeronautical Corporation, a subsidiary of the Dayton Airplane Engine Co., under the direction of Enea Bossi, who possesses the Italian Pilot's...
Experiments with Modified Tail Units.Experiments have been performed with 115th scale models of the original singleseater fighter and 120th scale models of the Bristol Fighter with a view to improving their spinning properties by redesigning the tail unit. The experiments with the fighter models...
THIS study has been conducted by the engineering section of the Aeronautics Branch for the purpose of developing a method of load factor determination which will be as nearly theoretically correct as possible, yet capable of being applied without difficulty by the average aeroplane manufacturer....
