AIR CONDENSATION EFFECTS AT M = 8.5 MEASURED ON THE DRAG AND THE WAKE OF A MAGNETICALLY SUSPENDED 20° CONE

摘要

Schlieren pictures of the near wake of a 20 cone and drag measured by magnetic balance both show effects of air condensation at temperatures below that predicted for condensation onset by previous work with othernindicators. Above this level supersaturated air may be used for hypersonicntesting with complete absence of effects due to air condensation.
