Nov 6, 2018 at 13:50 comment added uhoh @Hobbes I agree, have also voted to undelete.

Nov 6, 2018 at 13:02 comment added Hobbes MBM's deleted answer has the beginnings of a good answer: A drop tower that includes a brake mechanism to provide partial gravity would be an alternative to flying parabolas in an aircraft.

Apr 17, 2018 at 16:27 comment added Mark Adler Or you could just design your plant to be insensitive to gravity, and verify by operating it right side up, up side down, and maybe also sitting on its sides for kicks. Or run it while rotating in two axes.

Apr 17, 2018 at 13:56 comment added zephyr0110 Probably a cheaper solution would be to put a parachute, such that g - drag equals martian gravity. ...
Apr 17, 2018 at 11:47 comment added user20636 @GdD, simulation for testing (which seems to be the thrust of the question) is on-topic
Apr 17, 2018 at 11:05 comment added user20636 I was addressing your request for an estimate of duration, @uhoh,
Apr 17, 2018 at 8:56 comment added uhoh @GdD off topic is certainly a close reason, and you may be right in this case. In fact I may just delete this question and write a more appropriately-worded question for Aviation instead. However "...and should be on..." is never a reason to close. Where a question should be posted is not a votable issue. It's better not to propagate this notion to others, as this is not how SE works.

Apr 17, 2018 at 6:08 comment added user20636 what climb rate can you acheive in your token helicopter, and what altitude can it maintain a net -0.62g acceleration
Apr 17, 2018 at 4:55 comment added uhoh @RussellBorogove go for it! As long as it is survivable and repeatable.Answers to How many seconds of near-zero gravity are practical with a Reduced Gravity Aircraft? suggest well over 20 seconds are available at zero-g for fixed-wing aircraft, how many seconds might be possible here?
Apr 17, 2018 at 4:51 comment added Russell Borogove Define "aircraft". Take a helicopter to service ceiling, cut rotor speed to produce 38% of hovering lift, fall until terrified? VTVL rocket?
Apr 17, 2018 at 3:17 comment added uhoh @Antzi I've already put a link to this question there in chat.
Apr 17, 2018 at 2:54 comment added Antzi This question would be a better fit for aviation.stackexchange by the way
Apr 17, 2018 at 2:44 comment added Antzi @uhoh Oh I'm sure, you could achieve it given Space X budget :)
Apr 17, 2018 at 2:40 comment added uhoh @Antzi neither was landing rockets on top of boats ;-)
Apr 17, 2018 at 2:39 comment added Antzi Maybe with rotating wings you could achieve this, but it is'nt a realistic solution... To answer, you could look up the vertical acceleration profile of AF 447, which should be in the order of magnitude of the max acceleration of a horizontal plane
Apr 17, 2018 at 2:13 comment added Organic Marble I don't think the problem is the ground speed so much as constraining the attitude of the aircraft. For the zero gee case the plane has to fly at the zero lift angle of attack, for the Martian case there would likely be a specified angle of attack.
Apr 17, 2018 at 2:10 comment added uhoh @OrganicMarble The key is modulating the ground speed. I'm not sure it can be written off as impossible so quickly. However, the Beluga is great to know about, though perhaps a bit more expensive to fly up and down all day. Has it ever been used for reduced or zero gravity flights?
Apr 17, 2018 at 2:06 comment added Organic Marble Use this, the experiment will fit on a tilting frame inside it. en.wikipedia.org/wiki/Airbus_Beluga Seriously I think you have overconstrained your problem to the point that a conventional aircraft won't work.
