ok if i have worked this out right i can get 1 reveloution per 18.18ms so that would be something like 55g/s so a little under what i need but if i had four of these little blighters but the overal weight is still 100g that would mean this should hover with plenty left. If i also shrink the hole down to 1cm this should make it alot easyer. Is my maths correct or am i way off in the distance. Many thanks for the links i will look at them tonight. My current weight would be 100g this allows for 4 dc motors that weigh 20g each and allows for 20g for perspects. I never thought of using a cylindrical chamber i will look into this.

I am not to sure how else i can explain this. You have a 10cm wide by 10cm high 3d box filled with nomal air we breathe. At the bottom of the box there is a little whole at 2cm wide. Now a plunger pushes all the air from the top to the bottom and out the little whole. Then the plunger comes back up and sucks air back in. This is then repeated over and over again my question is would this system have the ability to make a 100gram item hover? If it could how many times per minute would this plunger need to go up and down to sustain a stable hover? If the load is to heavy what would be the weight it could carry? Or would the cube need to be bigger to get the necessary lift?

Ok now this is where i have a massive blond momment give me anything mechnical and i am fine but this i am lost. So i guess the simple question would be could a 10cm square shoot out 100g of air per second out at 10 m/s or how big would i cube need to be

Ow sorry about that i didnt no. Yep thats what i am trying to work out is this possibe is this going to generate enough lift to hover. I mean lets say we have 4 of these all at diffrent stages all pushing air out one at a time would this generate enough lift to make 100g hover or maybe more of less.

ok say say you have a 10cmx10cm 4d box filled with air and a little hole at the bottom say 2cm wide now say i was to push all of that air towards the hole. would this generate enough thurst to lift a 100g item

Im not to sure how would i know its a box in real life a square i think it would be 4d. How can i expand this question ?

Hi Guys im new to the forums but for the past year i had a great idea that i want to make happen. My first question is i can not work out thrust say for example i have a box 10x10x10x10cm pushing out air then sucking air in. So how would i work out how much thrust this would generate just buy pushing the air out once then how many RPM would it need to do to make a 100g item leviate. I hope i havent confused to many people .
