چکیده
Charts show variation In dynamic stability with rudder hinge-moment characteristics.Stabilizing rudder floating tendency combined with high degree of aerodynamic balance leadsto oscillations of increasing amplitude. Dynamic instability is increased by viscous fric-tion in rudder control system. Approximate method of calculating amplitudes of steady os-cillation is explained and Illustrated by a numerical example. More exact etep-by-atep cal-culation of motion shows agreement with approximation mathod. ROTE: Bequests for copies of this report must be addressed to: H.A.C.A.,Washington, D. C.

A Control Method Based on Dynamic Response of the Airplane for Compensation of Pilot-Induced Oscillations: Benefits and Flaws
Pilot-Induced Oscillation (PIO) is an unwanted, inadvertent phenomenon that has the ability to damage the aircraft completely. This paper suggests a novel control method that can damp PIO after predicting its occurrence. The specific point of this control algorithm is that it contains a preprocessor that will not let the controller be activated unless in the case of probable PIOs, so pilot comm...

متن کاملVariable-Structure Control of a Model Glider Airplane
A variable-structure control system designed to enable a fuselage-heavy airplane to recover from spin has been demonstrated in a hand-launched, instrumented model glider airplane (see figure). It has long been known that the most effective spin recovery technique for fuselage-heavy aircraft involves the use of ailerons to roll the airplane into the spin. This technique might be considered count...

متن کاملAn Efficient Numerical Scheme for Evaluating the Rolling Resistance of a Pneumatic Tire
The viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are ...
