Aerodynamic lift coefficient, drag coefficient and pitching moment coefficient are reported for a short finned body at angles of attack from -20 to 20 degrees as measured with the magnetic balance system at M.18 and .37, Re100 000 and 200 000. Also reported are modifications made to the magnetic balance system in order to extend the angle of attack range. A new controllable D.C. power supply was constructed using 300 ampere, 30 volt D.C. aircraft generators. The steady state and transient response characteristics of this power supply are reported.
