Task #2: Determine time until steady state<br />

Rough estimate:<br />

It takes about 1 step of non-dimensional time to delerate the system (with<br />

non-reefed, fully open parachute).<br />

t * g/V e<br />

t V e / g = 27.3 / 9.81 2.8 s<br />

Comparison with 2-DoF simulation<br />

(including free-flight phase without parachute):<br />
