A new short duration internal force balance for the High Enthalpy Shock Tunnel G¨ottingen (HEG) to measure lift, pitching moment and drag has been designed, calibrated and tested. The balance is able to measures forces of the order of milliseconds on instrumented models from angles of attack of -40 to 20Æ. Tests were performed on a 303 mm long, 10Æ half angle blunt cone at angles of attack from 0 to -20Æ. The tests were conducted at two test conditions with a Mach number of 7.8 and total enthalpies of 3.0 and 3.5 MJ/kg. At 0Æ angle of attack, the measured axial coefficient was recovered to within 6% when compared to computational fluid dynamic (CFD) simulations. A constant axial (drag) coefficient of 0.10 was obtained for the conical model over dynamic pressures ranging from 30 to 70 kPa. As the angle of attack was varied from 0 to -20Æ, the axial coefficient increased to 0.24, the normal coefficient decreased to -0.57 and the pitching moment coefficient (about the model tip) increased to 0.38. At -10Æ, the axial and normal coefficients were within 6% and 9% respectively of CFD predictions while the centre of pressure (based on chord length) was within 2%. Key words: Short duration force measurement; Hypersonic; Blunt cone; Shock tunnel.
