Trying To Fly At The Surface Pressure of Mars In a Vacuum Chamber

[@costarich8029]

Very interesting experiment. Instead of measuring the amount of weight reduction by trying to take off and fly, spin the fan backwards and press it down onto the scale to see how much force it is able to apply. Then you could grab some statistics like how much power it takes to generate a certain amount of lift. Be curious what that curve looks like.

[@76rjackson]

If the scale and motor had a small scaffold, perhaps made of heavy duty aluminum foil with a hole punched through it, positioned just under the propeller and resting on the floor of the chamber on 4 legs positioned around the corners of the scale, the downward thrust could be deflected and an accurate measurement taken.

[@alba2946]

you could also put the wheigt on a hanging scale...?

Though for more accurate testing nasa used a device to simulate mars gravity by using cables that lifted the ingenuity enough to counteract the extra force earth applies. Bu this is s good experiment he did nonetheless.

[@Razza2250]

to mimic the approach used to make this work for ingenuity, you would need a propellor with signifcantly higher blade pitch. This means that the prop would be directing a larger volume of air downwards at the same RPM as a one of lower pitch. You can see in the photo of ingenuity that the blades have a massively steep pitch close to the hub, which tapers out towards the leading edge. This design ensures that an even amount of thrust is produced all the way along the blade, where a consistent pitch would see the bulk of the lift being generated near the tips, placing enormous stresses on the hub due to leverage. It also helps the prop cope with high rotational speeds, as the centre of mass of each blade sits closer to the hub, but you are still getting the advantage of a larger total surface area compared to a smaller diameter consistent-pitch prop with similar CoG characteristics. I would highly recommend trying this experiment again, but with a 5" FPV quadcopter triblade such as the Gemfan Hurricane 51499 or the T-Motor 5150 props. These are rated for extreme RPMs (40,000+ is typical for high performance racing drones) and they have an aggressive pitch that tapers along the blade. You may need to 3d a similar "floating mount" like you have here to take advantage of the 5mm shaft of a brushless racing drone motor, such as a 2207, high Kv brushless motor to achieve the desired RPMs. NASA really have those big blades spinning very fast for their size to make it fly, I think you would get impressive results with a similar approach

@@ferrumignis No, they just create a pressure difference between the upper side and the lower one and this is why life is lost very quickly with altitude because the less initial pressure to work with, the less of a difference you can create.

[@darrylkinslow5613]

I'm not sure I would call that flying as much as getting flung off of the pins that are pushing it. That would mean it's getting a little lift, but it looks like the blades would have to spin a lot faster than the blades on Ingenuity seem to be in order to actually lift off, even just a little bit. If you did a frame by frame side by side with a modern ball shaped drone, it would probably compare very much to the apparent movement of Ingenuity, which it looks by your experiment, can't be done.

Put the scale under a transparent cover which is larger than the scale and rests on the floor of the vacuum chamber, with a small hole on top for the propeller shaft to go to the prop.

@@daviddavids2884 Most electric motors rely on air movement to remove heat that is generated internally due to inefficiencies. They have fans inside them to help with this. Quite often motors need to be de-rated when used at higher altitudes (for example in some places in Colorado that are much higher than sea-level), because the less dense air cannot contribute as much to the cooling of the motor. In a Mars atmosphere there will be much less atmosphere to help cool the motor. The motor's internal temperature will likely rise much faster.

Any chance of tossing some dust/sand on a panel and seeing if the helicopter can sweep it off in a Mars equivalent atmosphere? I've seen helicopters take off/ land and the amount of clearing force is considerable. Maybe NASA has already experimented with this, but it may be a viable option to clear solar panels on their equipment and I'd like to see if it'd work.

You got the attention of this quadcopter pilot. ✌😉

[@styxx5613]

We already know it's possible. NASA just did it.

[@fredbloggs5902]

Yes but it’s fun to watch anyway

You can see the circle holding the blades together flex out like crazy

What is "dimensional analysis"? used when making calculations for scaled models in fluid experiments? I failed to understand this in class

[@fredbloggs5902]

It’s a technique used to quickly check if equations make any sense whatsoever. The basic qualities (time, length, mass etc.) have to be the same on both sides. This is done before you start considering the quantities.

If you suspended a baffle above the motor and below the propeller you could get a better reading of total lift. Much like running your motor through your scale as far as results go .

Hi Action Lab...when I ride my bike under high power lines, my hands get zapped by a lot of static electricity from metal parts around the hand brakes (sometimes quite painful)! Can you explain why this happens and can you do an experiment to measure the amount of voltage that seems to float around in the air under high power lines? Thanks!

Fun experiment, I was wondering since you mentioned the gravity on mars (downward force) is about a third of the gravity on earth couldn't you just triple the pressure in the vacuum chamber (factor for upward force) to even the odds a bit?
