The report describes the experimental verification of the theory developed in Part I for ACLS in its stiff-mode operation. It also reports the discharge coefficient data required for computing air flow requirements. At low ground clearances, the theory was verified to be in excellent agreement with the experimental data obtained. At higher values of the ground clearance where the viscous flow theory is not expected to hold, appreciable difference between the experimental data and theoretical computation was observed. A multi-jet theory yet to be developed is expected to bridge the gap.
