Division 5.3

In the case of mechanical-transmission inertia braking systems, the following should be determined:

1. 5.3.1.

   The reduction ratio i_Ho measured at the mid-travel position of the control;

2. 5.3.2.

   The control-device output force P′ as a function of the thrust D on the drawbar; the supplementary force K and the efficiency are derived from the representative curve obtained from these measurements

   $${\eta }_{\mathrm{H0}}=\frac{1}{i_{\mathrm{H0}}}\times \frac{\mathrm{P\prime }}{D-K}$$

   (see Figure 2 of Appendix 1).
