The present report is concerned with a series of tests on a model airplane fitted with four types of dive flaps of various shapes, positions, and incidence, located near the leading edge of the wing (from 5 to 20 percent of the wing chord). Tests were also made on a stub airfoil fitted with a ventral dive flap (located at 8 percent of the wing chord). The hinge moments of the dive flaps were measured.
