Descent Characteristics
Reynolds Number Regime
Using the chart generated for Drogue design and our current simulation results, a reasonable range of Altitudes and Mach numbers is 0 to 100,000 ft and 0.1 to 0.8, respectively. Using the 1976 standard atmospheric model with no corrections, this puts the Reynolds number (with a reference length of 0.1524 m corresponding to the 6in diameter of the falling tubes) between ~5000 and ~3,000,000.
