Aerial navigation by dead reckoning

Aerial navigation by dead reckoning

Date: July 1922
Creator: Maffert, Pierre
Description: The problem to be solved, as presented to the pilot or observer of an aircraft, is as follows: The aircraft starting from A must land at B, the only data being the speed of the airplane, the altitude and the orientation D of the course. The above data would be amply sufficient, were it not for the fact that the airplane is constantly subjected to a wind of variable direction and strength.

Aerial navigation : on the problem of guiding aircraft in a fog or by night when there is no visibility

Aerial navigation : on the problem of guiding aircraft in a fog or by night when there is no visibility

Date: January 1922
Creator: Loth, William
Description: The use of magnetic fields and wire to navigate aircraft in conditions of poor visibility is presented. This field may be considered to be derived from a double lemniscate, considered in the particular case where the origin is a double point formed from the magnetic field of the slack wire, from the field produced by the return currents and from the field due to the currents induced in the conducting mass. These fields are dephased in two ways, one in the direction of the wire, the other in a direction perpendicular to it.

Aerial transportation

Aerial transportation

Date: February 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.

Air force and three moments for F-5-L Seaplane

Air force and three moments for F-5-L Seaplane

Date: February 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.

Air forces, moments and damping on model of fleet airship Shenandoah

Air forces, moments and damping on model of fleet airship Shenandoah

Date: 1922~
Creator: Zahm, A F; Smith, R H & Louden, F A
Description: To furnish data for the design of the fleet airship Shenandoah, a model was made and tested in the 8 by 8 foot wind tunnel for wind forces, moments, and damping, under conditions described in this report. The results are given for air of standard density. P=0.00237 slugs per cubic foot with vl/v correction, and with but a brief discussion of the aerodynamic design features of the airship.

Air reactions to objects moving at rates above the velocity of sound with application to the air propeller

Air reactions to objects moving at rates above the velocity of sound with application to the air propeller

Date: November 1922
Creator: Reed, S Albert
Description: There has been a tradition general among aeronautical engineers that a critical point exists for tip speeds at or near the velocity of sound, indicating a physical limit in the use of propellers at higher tip speeds; the idea being that something would occur analogous to what is known in marine propellers as cavitation. In the examination of the physics pertaining to both propellers and projectiles moving at or above 1100 feet per second, the conclusion was reached by the author that there is no reason for the existence of such a critical point and that, if it had been noted by observers it was not inherent in the phenomena revealed, but rather due to a particular shape or proportion of the projectile and that, with properly proportioned sections, it would not exist.

Airplane stability calculations and their verification by flight tests

Airplane stability calculations and their verification by flight tests

Date: July 1, 1922
Creator: Rota, Augusto
Description: For some time, the designers of airplanes have begun to occupy themselves with the question of longitudinal stability. In their quest to simplify calculation and data collection, the designers have attached the greatest importance to the coefficient of initial longitudinal stability. In this study a diagram was constructed from the data of the tunnel tests, which depends neither on the position of the center of gravity nor of the angle of deflection of the elevators. This diagram is constructed by means of straight lines drawn through the metacenters of the complete airplane, in a direction parallel to the tangents to the polar of the airplane relative to a system of axes fixed with reference to the airplane.
