no. it needs some viscous drag to throw the water and drag the ship forward... feel like a block just gliding in frictionless plane...
No, the propeller will only work if the engine is running.
A propeller works by converting the rotation of the engine into horizontal thrust similar to a fan. The blades push the air backwards creating acceleration, and create a difference in pressure between the forward and rear surface adding to the movement. The above is, of course true for a boat propeller. For an airplane propeller Bernoulli's pincipal is involved. Bernoulli's principle states that the greater the speed of a fluid, the less the lateral pressure. So the propeller uses the same deal as the wing.
Any fluid that has no resistance to shear stress and no compressibility is called "Ideal Fluid"
It propels.
the motor spins the propeller like a turbine. isn't it obvious, idiot .
Ideal Fluid:An incompressible fluid that has no internal viscosity.
An airscrew is a propeller of an aircraft, or an actuator disc whose working fluid is air.
It moves.
Yes, theoretically, if it had an engine that would allow it to move as fast in a thinker environment at the same speed. That would be hard.
The curved shape of the propeller deflects airflow to it's rear. This is 'thrust' that propels an aircraft.
Where the gun fires through the propeller, the two are mechanically connected and timed so that the rounds will pass between the blades of the propeller.
