This is a very general answer to your question. A variable pitch propeller can be turned . If the blades were flat faceing forward they would not do their job. When the blades are turned at a slight angle (the pitch) then they bite into the air and this helps with forward movement. The more pitch the better the blades cut into the air, but if the pitch is to much, then the blades no longer cut into the air and forward motion stops. The blades can be set for reverse pitch which allows a plane to slow down very quickly once it has landed on a runway (this helps to save on the brakes) and can also be used to back a plane up, such as from a boarding gate, or to park a plane.

A screw's pitch is the amount it moves forward per turn. An airscrew (propellor) pitch is the same concept.
yes but it dependes you see trains aren't very areodynamic, but if they have wings and a propellor yes they can.
A typical aircraft propellor cuts through the air much like a screw and provides thrust to the aircraft. Many of the modern airplanes have propellors which are variable pitch and they change pitch so that it can increase the blade angle to grab more air or decrease the angle to grab less. When the pitch is changed by the pilot, both (or all 3 or 4) blades change pitch at the same time and the same angle. === === The main rotor blades of a helicopter provides lift and thrust for forward motion. To do this, the rotor controls input a pitch control to the Blade that is moving to the Aft and decreases pitch to the blade moving forward or vice versa. Therefore, unlike the typical airplane propellor, the helicopter blades do not have the same pitch ange. One result of this is that the loads on the blade attachments (or grips) and the Mast have higher bending loads and torque loads and the loads are not symmetrical as it would be with regular propellor blades.
1. first put on the propeller hat. 2. then click on your dance and you will be flying.
You can play Jet-pack adventure with it, where they'll fly around using their propellor hats!
Propellor Time was created on 2010-03-22.
An aircraft that has more than 2 propellor blades per engine. Multi-blade engines usually included the capablity to vary the pitch of the propellor in order to pull more air. Multi-engine aircraft are aircraft with more than 1 engine.
This stereo comes with a control knob for variable pitch.
Variable pitch propeller
The spelling "propellor" is a variant.The usual spelling is propeller (spinning blades to push or pull in air or water).
