The propeller blades are angled in the opposite direction, sort of like an airplane flying on its back. Of course, the propeller's blade twist from hub to tip is inappropriate, and the camber of the airfoil is wrong when thrust is reversing, but efficiency of the propeller is not of paramount importance during that phase of operation.
They rotate and produce forward movement through thrust.
Sort of. Some planes can reverse the thrust of their engines. Propeller aircraft can change the pitch of their propellers so it can "bit" more air. Some can be reverses in pitch so that it is provide zero thrust.
Reverse pitch propellers allow the propeller blades to rotates to an angle that produced thrust in the opposite direction direction of flight. This allows propeller driven aircraft to stop faster than they would with braking alone.
that is a fine answer
Yes they can
Planes generate thrust by using jet engines or propellers. Jet engines work by taking in air, compressing it, mixing it with fuel, and igniting it to produce a high-speed exhaust that propels the plane forward. Propellers create thrust by rapidly spinning and moving air backwards to create a forward force.
They propel the aircraft by propellers or jet thrust.
Thrust. The pull of the propellers, the push of the jet engine, the pull of gravity.
Propellers would not work in space because they rely on the presence of air to generate thrust through the movement of blades. In the vacuum of space, there is no air or atmosphere to create the necessary lift. Instead, spacecraft use rocket engines that expel gas at high speed to produce thrust, adhering to Newton's third law of motion. Thus, while propellers are effective in atmospheric conditions, they are impractical for the vacuum of space.
maximum thrust is obtained.
You can set the thrust idle point, which means that if you pull the levers back beyond that your get reverse thrust.
If you are moving forward, the propellers are pushing it, if you are moving in reverse, the propellers are pulling it.
