Freefall in openrocket

[tejt]

Hi, is there any way to simulate free fall / drop test from a certain altitude to landing point?

Thanks.

I would think a 2nd stage with an MMX motor would probably get the job done by setting separation to apogee if the first stage.

Pick a motor to reach apogee at the desired altitude. Then fire ejection charges at apogee, and descent without a parachute.

Note that unless you separate the airframe at apogee, it will come back down ballistically, at significantly greater speeds then if you were to separate the airframe. If that is your desired scenario (hope not), then set ejection charge to fire at a time that's greater than the total flight time.
