Helicopter torque reaction?
Im sorry in advanced if this has been previously been covered, but iv searched the net and this forum and didn't find what i am looking for. At work im currently studying the helicopter theory of flight and we've come onto the topic of torque reaction. Now i know that it involves Newton's law stating that everything has to have an equal and opposite reaction opposing it, but what i do not understand is how the force is physically created in the opposite direction to the spinning rotor blades. At first it seemed logical for the body of the aircraft to want to spin in the same direction to the rotor, not against it but taking Newtons law into consideration it makes sense to spin in the opposite direction to the rotor blade. Im imagining that it must be the force of the fixed main rotor gear box acting on the mechanism to turn the the blades? Im not to sure however. Any input helping shed light on the matter would be much appreciated.
