Modern Inertial Technology: Navigation, Guidance, and ...
While an instrument is sensing a steady nonaccelerating rotation, it gives the
correct output, but under angular acceleration it gives a transient rate or
acceleration error. Defining the pendulosity as the product of the sensing mass (
m) and the ...
previously (paragraph 6), the arc rate between these two planes ( Pj' ) la
proportional to the amount of tilt T and the rate of turn R; or we can say that it
equals K'.T.R., where K' is a constant. Pendulosity Turn Error was shown in Fig. 3
to be a ...
At other airspeeds or rates of turn the pendulosity turn error will be present but to
a lesser extent than if no compensation were made. In exhaustive flight tests of
artificial horizons subject to pendulosity turn error made by the Royal Aircraft ...

Air, space and instruments
This last fact is not too surprising, inasmuch as pendulosity is an essential
operating requirement in a gyrocompass. The minimizing of error is obtained by
tuning the natural period of oscillation of either the pendulum or the gyrocompass
in the ...

Proceedings of the ... American Control Conference
Translational Vibration in Rotor Plane at 2N Frequency" If the gyro's gimbal
exhibits pendulosity in a direction perpendicular to the spin axis, translational
vibration at twice-spin frequency in the rotor plane will cause gyro drift. Figure 3
shows ...

Gyroscopic theory, design, and instrumentation
In normal operation the spin axis is nearly horizontal while the pendulosity is
downward. Consider a gyrocompass started with its spin axis horizontal and
pointing a few degrees east of north. If there were no pendulosity, the spin axis
would ...

Encyclopaedia Britannica: a new survey of universal knowledge
A gyrocompass is a gyroscope having a frame with a mass unbalance giving it a
pendulosity at right angles to the spin axis. In normal operation the spin axis will
be nearly horizontal and pointed north, while the pendulosity is downward.

Aircraft Instruments: Principles and Applications
The pendulosity error resulting from a turn may be analysed in a manner similar
to that of erection errors. In Fig 5.21 an aircraft is again considered as turning to
starboard through 360° from the point A. As the turn is entered the PATH OF TOP
