Thrust
A propeller is like a spinning wing. The airfoil shaped blades pull an airplane forward just as an airplane's wings lift it upward. The amount of thrust created by a propeller depends on how fast and at what angle its blades cut through the air. The propeller is generally powered by a combustion engine which fires pistons and turns the propeller.
The force generated by a six blade propeller on a plane is determined by factors like the size and pitch of the blades, the engine power, and airspeed. The propeller creates thrust by accelerating air backwards, which propels the plane forward in reaction. The force produced will vary depending on the specific design and operating conditions of the propeller.
The motors or engines. The propeller(s) generate forward thrust on piston or turbo-prop aircraft, and on jet aircraft, thrust is created both by combustion exhaust and by bypass air from the fan(s).
Axial fans are designed to move air parallel to the fan blade rotation axis, making them more suitable for applications requiring high airflow at lower pressures. Propeller fans have angled blades that push air in a specific direction, making them more efficient for moving air over long distances at higher pressures. Overall, axial fans are better for general cooling and ventilation, while propeller fans are ideal for air circulation and ventilation in specific directions.
Before the spinning jenny was invented, spinning was done by hand using a spinning wheel or a distaff and spindle. These manual methods were time-consuming and labor-intensive, limiting the amount of yarn that could be produced. The spinning jenny revolutionized the textile industry by allowing one person to spin multiple threads at once, increasing efficiency and productivity.
The spelling "propellor" is a variant.The usual spelling is propeller (spinning blades to push or pull in air or water).
The spinning shaft from the engine to which the propeller is attached.
Spinning propeller
They both exist.
The propeller or the "prop" or "screw" is the device that propels the vessel through the water by spinning , this is different from a jet drive, which sucks in water and shoots it out to push the vessel through the water.
A pull propeller is more efficient due to the fact it is in clean/non turbulent air.
Reciprocating engines are very big engines. Instead of a motor just spinning the propeller, electric arms would move up and down circling around the propeller line spinning it. These kind of engines were used on the titanic.
a Propeller
No. A submarine's propeller relies on the water around it for something to push against. As space is a vacuum, the propeller would have nothing to push against, ergo the submarine would have no thrust.
They both exist.
Propeller seeds from a tree help in dispersing its seeds by spinning as they fall, allowing them to be carried by the wind to new locations where they can grow into new trees.
Neither a spinning real or push button type reel are used in fly fishing.
