Ground-effect tests were made in the LMAL 7- by 10-foot tunnel of a model of a low-wing, pursuit-type airplane equipped with a full-span 25-percent-chord slotted flap. The model was mounted at two heights above a flat plate that represented the ground and was tested with and without power. At each height and power condition, tests were made with two stabilizer and several elevator settings. Tests were also made with the tail removed. Sufficient data were obtained to determine the elevator deflection required for trim and the downwash angles in the region of the tail at each lift coefficient. The downwash angles derived from the power-off test data for one height above the ground were compared with computed angles.
