Pressure distribution on wing ribs of the VE-7 and TS airplanes in flight

Description: This paper is the first of a series of notes, each of which presents the complete results of pressure distribution tests made by the National Advisory Committee for Aeronautics, on single-wing ribs of the VE-7 and TS airplanes for a particular condition of flight. The level flight results are presented here in the form of curves and show the comparison between the pressure distribution over a representative thin wing, R.A.F.-15, and a moderately thick wing, U.S.A.-27, throughout the range of angle of attack.

Mass distribution and performance of free flight models

Description: This note deals with the mass distribution and performance of free flight models. An airplane model which is to be used in free flight tests must be balanced dynamically as well as statically, e.g., it must not only have a given weight and the proper center of gravity but also a given ellipsoid of inertia. Equations which relate the motions of an airplane and its model are given. Neglecting scale effect, these equations may be used to predict the performance of an airplane, under the action of gravity alone, from data obtained in making dropping tests of a correctly balanced model.

Glider Construction and Design

Description: The endeavor to draw a strict line between gliders and soarers as been recently abandoned and the following classification adopted: 1) gliders controlled by shifting the weight of the body; 2) gliders controlled by rudders; 3) gliders controlled by wings. The different classes are discussed as well as materials and parts used in construction.

Slotted-Wing Airplanes

Description: Different applications of the slotted-wing principle are discussed as well as the advantages of using them. Slotted-wings are provided as a promising solution to the problem of needing to increase flight speed for aircraft while also decreasing landing speed.

Pressure Distribution Over a Rectangular Monoplane Wing Model Up to 90 Degree Angle of Attack

Description: "The pressure distribution tests described in this report, covering angles of attack up to 90 degrees, were made on a rectangular monoplane wing model in the atmospheric wind tunnel of the Langley Memorial Aeronautical Laboratory. These tests indicate that a rectangular wing, by reason of its large tip loads, is uneconomical aerodynamically and structurally, has pronounced lateral instability above maximum lift, and is not adaptable to accurate calculation based on the classical wing theory" (p. 197).

The De Havilland "Tiger Moth": A Low Wing Monoplane

Description: With a speed of 186.5 M.P.H. and an operational altitude of 20,000 feet the De Havilland Tiger Moth has caused comment as it was introduced just before the King's Cup race of 1927. It is a single seater with unusual control configuration due to the cramped cockpit area.
