Aerial transportation
Date: February 1, 1922
Creator: PIERROT
Description: The origin of air traffic dates from the war. The important development of aeronautic industries and the progress made in recent years, under the impelling force of circumstances, rendered it possible, after the close of hostilities, to consider the practical utilization of this new means of economic expansion.

The aerodynamical laboratory of the Vienna Technical High School
Date: February 1, 1922
Creator: Katzmayr, R
Description: We will give here only a short explanation of the operation of the plant and deal principally with the question of what it has accomplished.

Air force and three moments for F-5-L Seaplane
Date: February 1, 1922
Creator: unknown
Description: A model of the F-5-L seaplane was made, verified, and tested at 40 miles an hour in the 8' x 8' tunnel for lift and drag, also for pitching, yawing and rolling moments. Subsequently, the yawing moment test was repeated with a modified fin. The results are reported without VL scale correction.

Deterioration of airplane fabrics
Date: February 1, 1922
Creator: Wendt, FR
Description: The observation that airplane fabrics, after long use, lose their original strength, caused the German Experimental Institute for Aviation to carry out a series of experiments on the effect of weathering on the cloth covering of airplane wings and fuselages.

The efficiency of a wind tunnel
Date: February 1, 1922
Creator: Miller, Wm H
Description: If, by some means, a steady state of motion of a perfect fluid were established in an ideal wind tunnel, there would be no losses, and the motion would persist indefinitely. In the actual tunnel, the function of the motor-fan group is overcome by the total loss of head in the tube due to friction and eddies.

Impact tests for woods
Date: February 1, 1922
Creator: unknown
Description: Although it is well known that the strength of wood depends greatly upon the time the wood is under the load, little consideration has been given to this fact in testing materials for airplanes. Here, results are given of impact tests on clear, straight grained spruce. Transverse tests were conducted for comparison. Both Izod and Charpy impact tests were conducted. Results are given primarily in tabular and graphical form.

Manometer for recording air speed
Date: February 1, 1922
Creator: Wieselsberger, C
Description: If it is desired to record the pressure difference given a gauge, the manometer must answer the following conditions: 1) It must respond quickly so that all speed variations will be correctly recorded; 2) It must not be affected by rectilinear or curvelinear accelerations. Hence, movable parts must be counterbalanced. An instrument which met these criteria is discussed as well as details of construction.

Marking airdromes
Date: February 1, 1922
Creator: James, P
Description: Necessity of adopting for all aviation fields, civil or military, a single system of markers for giving the direction for starting and landing (with an automatic indicator of the direction of the wind) and of indicating the good part of the field.

The problem of landing
Date: February 1, 1922
Creator: Pistolesi, E
Description: The author discusses various aspects of landing aircraft such as the actual process of touchdown and the problems associated with the tail skid touching the ground before the landing gear.

Surface area coefficients for airship envelopes
Date: February 1, 1922
Creator: Diehl, W S
Description: In naval architecture, it is customary to determine the wetted surface of a ship by means of some formula which involves the principal dimensions of the design and suitable constants. These formulas of naval architecture may be extended and applied to the calculation of the surface area of airship envelopes by the use of new values of the constants determined for this purpose. Surface area coefficients were calculated from the actual dimensions, surfaces, and volumes of 52 streamline bodies, which form a series covering the entire range of shapes used in the present aeronautical practice.
