radial acceleration


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

ra·di·al ac·cel·er·a·tion

the centripetal acceleration of a particle or vehicle moving along a curved path at a constant velocity; for example, turning a curve in an automobile, pulling out of a dive, or performing a loop maneuver in an aircraft. In aviation, acceleration varies directly with the square of the air speed and inversely with the radius of the turn (a = V2/r, where V is air speed and r is radius of turn).

A plot of the QCM radial accelerations near the equilibrium radii for all 7 planets is shown in Fig.
The sums of two radial accelerations with respect to the transmit array and the receive array for three targets are 400 m/[s.sup.2], 500 m/[s.sup.2], and 450 m/[s.sup.2], respectively.
Another remark arises from Figure 2(b): the effect of the gravitational acceleration g on the measured signals must be taken into account and removed in order to get the correct value of the radial acceleration. This is due to the fact that the measurement axes of the accelerometer on the pendulum have an orientation that largely changes over time, while most of dynamics applications do not show such a behaviour.
In this study, a device and a method for the in situ measurement of a roll shell runout, based on the radial acceleration measurement of the surface, is described.
