Abstract
THE increasing use of low‐wing monoplanes has emphasized the susceptibility of this type of aeroplane to detrimental wing‐fuselage interference. This interference was first indicated by the inferior aerodynamic characteristics of the low‐wing as compared with the high‐wing monoplane.

Abstract
DURING the past eight or ten years the speeds of most types of aeroplanes have been practically doubled. Part of this impressive advance has resulted from the use of increased power, but most of it has come from the reduction of aerodynamic drag. The largest and most obvious “built‐in head winds” such as exposed engine cylinders, landing gear struts and wires were first eliminated and attention was then directed to successively smaller factors. The stage has now been reached where it is necessary to consider the effects on drag of such items as rivets, sheet‐metal joints and other irregularities on the surfaces exposed to air flow.

Abstract
IT is not here proposed to list all the aero‐planes in use with the Deutsche Luftwaffe, but only to describe some representative examples of the latest equipment. The German policy is known to have been the development primarily, of a strong striking force, so that the first really modern aeroplanes to be issued to the re‐born air arm were bombers. In the first place these were converted Junkers Ju 52–3m, followed by the military version of the Ju 86. Even the Heinkel He 111k, which is still one of the main bomber types, was flown as a prototype in 1936 in the nominal guise of a high‐speed passenger and mail aeroplane.

Abstract
This report is a sequel to P.Sc.T. No. 108 and develops the author's two‐dimensional theory, extending it to the study of three‐dimensional movements—sub‐sonic, sonic, and super‐sonic. The variables used are φ the speed potential; ψ1 and ψ2, two functions of the current; and t, the time.

Abstract
The applications of the inverse Wiedemann effect to torque measurements and to torque variation recordings were devised by the writers and the details of the experiments were published in the Reports, Vol. IV, No. 52, and Vol. V, No. 54 (see AIRCRAFT ENGINEERING, Vol. II, July 1930, p. 186. If a ferro‐magnetic bar is furnished with a twisting arm, a force, or variations of a force, can be measured in the same way. The writers constructed a pressure indicator for an internal‐combustion engine and obtained satisfactory results.

Abstract
In an aircraft, a revoluble thrust‐producing system including a hub, a generally radially disposed airfoil blade pivotally secured to and carried by said hub by a corresponding single pitch‐varying blade‐root pivot whose axial line of pivotation is fixed in relation to the longitudinal axis of the blade‐root and passes outwardly from said hub on the back or pressure side of the airfoil blade in a generally radial direction and diverges from the airfoil blade as it goes outwardly from said hub, and passes through the stable region of the resultant air‐load vectors of the airfoil.
