Altitude measurement for model rocketry
Relation between the maximum altitude and the flight time for a rocket with a terminal velocity of .
Fractional error in the flight time as a function of the dimensionless parameter . The solid line represents the exact relation given in Eq. (23); the dotted line represents the asymptotic formula given in Eq. (25).
Flight times in nonuniform atmosphere with exponentially varying density. Terminal velocity, based on constant, standard sea-level density, is .
Fractional error in the altitude for uniform and nonuniform atmospheres. The terminal velocity is the same as in Fig. 3.
The velocity profile as a function of the altitude for uniform (dotted lines) and nonuniform (solid lines) atmospheres. The terminal velocity, for standard sea-level density, is and the initial velocity is . The terminal velocity based on the local density is shown by the dash-dotted line.
