What are stick position stability and stick force stability?

Webforce gradient (with fixed stick inertia) in Sikorsky's motion base simulator. The simulation model was based on early CH-53K control laws with both rate command attitude hold, and attitude command velocity hold control modes. This study provided valuable insight into the effects of changes in control travel and force gradient, but WebThe slope of the stick force against airspeed curve must be stable and have a gradient not less than 1 lb per 6 knots ...

WebA stick force gradient is the change in stick force as the airspeed deviates from trim condition. An aircraft’s yoke force gives pilots haptic feedback which improves their situational awareness without the need to assess instrument readings. A high stick force gradient will give the pilots a lot of feedback but will require more physical ... WebThe critical dependence of this stick-force gradient on ele- vator hinge-moment parameters and on mass unbalance of the control system was shown in reference 2. It was found that a given stick-force gradient can be obtained by any of a series of combinations of these parameters satisfying certain prescribed relations. WebA central force is one for which in some choice of coordinates, \[ \begin{aligned} \vec{F}(\vec{r}) = f(\vec{r}) \hat{r}. \end{aligned} \] The concept is that the origin (i.e. the center of our coordinate system) is the source providing our central force, and the force at any point \( \vec{r} \) always points towards or away from this center.
