The 127 is a cantilever monoplane without external bracing. It is designed to accompany and protect bombardment and observation aircraft. Descriptions of the airfoil, fuselage, power plant, landing gears, and armament are provided.

Part I of this paper covers the constructional design of metal flying-boat hulls and does not elaborate any further. Part II deals with the actual construction process of the hull.

As a rule, the actual lift distribution at the wing tips shows deviations from the theoretical distribution, so that an approximate evaluation of the distribution may be regarded as satisfactory. After a few brief remarks on the fundamentals of the exact computation, the method will be so presented that the lift distribution for deflected ailerons may be determined for other values of the parameter p from the results already obtained. Coefficients will then be given in the form of diagrams and numerical tables, from which the desired forces and moments can be easily obtained by substitution in the given equations.

An investigation on the cowling of radial air-cooled engines was conducted in the 20-foot Propeller Research Tunnel at Langley Field. Cooling and drag tests were made with each form of cowling. The propulsive efficiency was found to be practically the same with all forms of cowling.

The Goldfinch is equipped with the Bristol Jupiter Mark Vii engine. It is the all metal version of the Gloster Gamecock used by the R.A.F. A description of the construction, components, flying qualities, characteristics, drawings, and photographs are provided.

This report examines the take-off conditions of airplanes equipped with tractive propellers, and particularly the more difficult take-off of airplanes heavily loaded per unit of wing area (wing loading) or per unit of engine power (power loading).

"The results of an investigation to determine the pressures in the open cockpit of a Vought VE-7 airplane are given. The information has been considered valuable on account of its possible effect upon the operation of instruments, particularly altimeters, due to a variation from the true static pressure which is induced by the passage of the airplane through the air. The observed values are small and the effect upon instruments is inconsiderable" (p. 1).

The Villiers 24 C.A.N. 2 is a night pursuit sesquiplane equipped with the 450 HP direct-drive Lorraine 12 Eb engine. It is characterized by Handley Page slotted wings. Details of the construction, wings, flaps, controls, characteristics, performances, drawings, and photographs are provided.
