A simplified model of forces due to idling power, aerodynamic
drag and rolling resistance is obtained from speed and acceleration
data in ground testing on the Falcon 20. The model is applicable
from speeds near to zero to at least 200 ft/s. The overall system
of instrumentation and aircraft configuration may be expected to be
capable of providing decelerating forces with a precision of ± 250
lbf at the 95% confidence level.
In conjunction with effects of mechanical properties of snow,
the model is used to calculate total decelerating forces arising
when rolling on snow-covered runways. Resulting
accelerations are integrated over time to produce histories of
speed that compare well with measured data.
