The
machine tests a pair of scaled-down brake rings under scaled braking
conditions, which simulate taxi and landing conditions of an airplane.
The translational energy of the aircraft is simulated via the
rotational energy of the inertia section, in the section painted
yellow. The rotational inertia is selected by adding or removing disks
of various sizes to the axis. The range of inertias is 0.2 to 4.625
slug-ft2 (2.7 – 6.3 kg-m2). The maximum initial rotational speed is
5000 rpm (524 rad/s). The brake control of the machine can be operated
in either constant torque or constant load mode.
