Hi, I am very sorry if I have posted in the wrong forum, I don't know wether to post in classical physics or aerospace engineering. I have been wondering this theoretical thing a lot lately and I can't figure it out, it should have a simple straight answer though so your help is very appreciated. Its not anything practical of course, or to be built or efficient of course, it is just a theoretical question I have.
A rigid wide t-bar out of plastic/wood etc is made. On it sit 6 individual PERFECTLY identical propellers/pumps with perfectly identical thrusts. The propellers´/pumps´ diameters are smaller than the width of the wood plate that the propellers are sitting on.
Simply, will the propeller/suction pump arrangement have a net force towards one direction as in the picture? or would there be no movement/force at all. (considering ofcourse that in theory each individual propeller/pump give the exact same thrust as the other). The medium is air but also could be water. The air/water motion direction imparted from the propellers are the blue arrows.
The two arrangements are seen in the picture.
Thanks
