A Decade Of Starspot Activity On The Eclipsing Short-Period RS Canum Venaticorum Star WY Cancri: 1988-1997
We present optical photometry of the short-period eclipsing RS CVn system WY Cancri for the years 1988–1997. For each light curve, we model the distortion waves in order to study the behavior of starspots in this system. After removing the spot effects f
A method for estimating variations in the roots of the lateral-stability quartic due to changes in mass and aerodynamic parameters of an airplane
Theoretical analysis of the longitudinal behavior of an automatically controlled supersonic interceptor during the attack phase against maneuvering and nonmaneuvering targets
Theoretical analysis of the longitudinal behavior of an automatically controlled supersonic interceptor during the attack phase
A theoretical analysis of the effect of engine angular momentum on longitudinal and directional stability in steady rolling maneuvers
Theoretical Analysis of the Longitudinal Behavior of an Automatically Controlled Supersonic Interceptor During the Attack Phase
Theoretical analysis of the longitudinal behavior of an automatically controlled supersonic interceptor during the attack phase against a nonmaneuvering target is presented. Control of the interceptor's flight path is obtained by use of a pitch rate command system. Topics lift, and pitching moment, effects of initial tracking errors, discussion of normal acceleration limited, limitations of control surface rate and deflection, and effects of neglecting forward velocity changes of interceptor during attack phase
A theoretical analysis of the effect of engine angular momentum on longitudinal and directional stability in steady rolling maneuvers
Effect of automatic stabilization on the sideslip and angle-of-attack disturbances in rolling maneuvers
An analysis of the lateral stability of the Douglas D-558-II airplane equipped with a yaw damper, with special reference to the effect of yaw-damper rate-gyro spin-axis orientation
