Configuration Remarks
Body Primarily bodies of revolution, or close approximations are treated. Transonic methods for most of the aerodynamic data do not exist. The recommended procedure requires fairing between subsonic and supersonic data using available data as a guide.
Wing, horizontal tail Straight tapered, cranked,or double delta planforms are treated. Effects of sweep, taper and incidence are included. Linear twist is treated at subsonic Mach numbers. Dihedral effects are present in the lateral directional data.
Body-wing body-horizontal Longitudinal methods reflect only a mid-wing position. Lateral directional solutions consider high and low-wing positions.
Wing-body-tail Various geometry combinations are possible. See table 2 in the printed version for full details. Wing downwash methods are restricted to straight tapered planforms. Effects of twin vertical tails are included in the static lateral directional data at subsonic Mach numbers.
Non-standard geometries Non-standard configurations are simulated using "basic" configuration techniques. Strakes can be run via a double-delta wing. A body-canard-wing is input as a wing-body-horizontal tail. The forward lifting surface is input as a wing and the aft surface as a horizontal tail.
Special configurations Low aspect ratio wing or wing-body configurations (lifting bodies) are treated at subsonic speeds. Two-dimensional flap and transverse jet effects are also treated at hypersonic speeds.
