An investigation was made in the Langley 300 MPH 7- by 10-foot tunnel to determine the static stability characteristics of a cambered-delta-wing model. The cambered delta wing was derived from a segment of a cone selected so that the projected plan form with a wing dihedral angle of zero degrees was the same as a 60 degree delta wing. The projected plan form had an aspect ratio of 2.31.

An investigation at high subsonic speeds was made in the Langley high-speed 7- by 10-foot tunnel to determine the static stability characteristics of a cambered-delta-wing model with wing dihedral angles of 20 to 50 degrees. The cambered delta wing was selected so that the projected plan form with a wing dihedral angle of zero degrees was the same as that of a 60 degree delta wing.

An investigation was made to determine the effects of wing position and fuselage size on the low-speed static and rolling stability characterististics of airplane models having a triangular wing and vertical tail surfaces.
