Motion of the Two-Control Airplane in Rectilinear Flight After Initial Disturbances With Introduction of Controls Following an Exponential Law

Description: "An airplane in steady rectilinear flight was assumed to experience an initial disturbance in rolling or yawing velocity. The equations of motion were solved to see if it was possible to hasten recovery of a stable airplane or to secure recovery of an unstable airplane by the application of a single lateral control following an exponential law. The sample computations indicate that, for initial disturbances complex in character, it would be difficult to secure correlation with any type of expon… more

An Investigation of the Elements Which Contribute to Statical and Dynamical Stability, and of the Effects of Variation in Those Elements

Description: Part 1 gives details of models tested and methods of testing of the Eiffel 36 wing alone and the JN2 aircraft. Part 2 presents a statistical analysis of the following: lift and drag contributed by body and chassis tested without wings; lift and drag contributed by tail, tested without wings; the effect on lift and drift of interference between the wings of a biplane combination; lift and drag contributed by the addition of body, chassis, and tail to a biplane combination; total parasite resista… more

Longitudinal Stability in Relation to the Use of an Automatic Pilot

Description: "The effect of restraint in pitching introduced by an automatic pilot upon the longitudinal stability of an airplane has been studied. Customary simplifying assumptions have been made in setting down the equations of motion, and the results of computations based on the simplified equations are presented to show the effect of an automatic pilot installed in an airplane of known dimensions and characteristics. The equations developed have been applied by making calculations for a Clark biplane an… more
