The Measurement of Aerodynamic Forces on a Short Body at High Angles of Attack with the Magnetic Balance System.

Abstract

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, Re=100 000 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.
