Autopilots that add the
yaw axis (rudder) typically only do so with an optional "yaw damper."
As indicated in Figure 3, the platform had a small (< 1[degrees]) oscillation in the roll and pitch axes and a constant rotation about the
yaw axis. A variable starting location was used to investigate the effect of the lower GDOP and ADOP at high latitudes.
Another separated technique is tuning one axis at a time, from roll, pitch, and then
yaw axis, while the quadrotor hovers.
Existing lens-based stablizers can only correct for vibrations on two axes of motions, the pitch axis and
yaw axis, even though the most common type of unwanted shaking during photography actually takes place on the roll axis.
In fact, in spite of a better maneuverability at high AOA (Angle Of Attack), the FSW is characterized by a significant directional instability about the
yaw axis, is subject to aeroelasticity issues at the wing tip, and is pretty unstable in stall conditions.
Incorporating new technologies, Butler National designed, manufactured and obtained Federal Aviation Administration Supplemental Type Certificate (STC) approval of a replacement rate sensor for use by the autopilot on the roll axis and
yaw axis of the applicable Learjet 31/35/35A/36/36A/C-21A and 55 Series airplanes, and on the
yaw axis on the Learjet Model 24/25/28/29 Series airplanes.
The aerodynamics moment components forroll, pitch and
yaw axis are represent as L, M and N.
He found that moving the rear wheel axle shifts the weight distribution on the rear and caster wheels, which has a significant effect on what he called "
yaw axis control." This
yaw axis control is defined as "the forces required to maneuver the wheelchair." The turning resistance curves from Frank and Abel indicate a doubling of the resistance from a caster load of 100 N to a caster load of 160 N [5].
Dual rudder and vectored-thrust control on the
yaw axisThe wingspan is but 21 feet, the fuselage length 19.3 feet, making for a short-coupled feeling along the
yaw axis. Standard empty weight is about 630 pounds, although the version we flew weighed 654 pounds.
