the limitations of rotor spinning are................
1. successive count range up to 40 Ne,
2. strength is lower in compare to ring spinning,
3. the cotton should be clean,
4. variation in twist,
5. the luster is duller.
A rotor.
The spinning rotor lifts it. The rear rotor stabilises it.
Rotor
Locked rotor current is the amount of current a motor would draw if you energize the motor and the rotor (the spinning shaft) doesn't spin.
Some helicopters feature a second rotor underneath the first rotor that counters the force applied to the body of the helicopter by applying thrust in the opposite direction of the main rotor. This stops the helicopter from spinning around. Others, instead of a second rotor underneath the first rotor have a back rotor that essentially does the same thing, which is provide a equal force to the first rotor preventing the helicopter from spinning =0
Gunter Trommer has written: 'Rotor spinning'
The rotor blades when spinning creates what is called the rotor disk, the disk is tilted in the direction that the pilot wishes to go.
The back rotor of the helicopter counters the force applied to the body of the helicopter by the main rotor by applying thrust in the same direction as the main rotor. The force from the main rotor is applied in the opposite direction the main rotor is spinning. So say the force the main rotor was exerting on the body of the helicopter was causing the tail to move left then the back rotor would be designed to apply an equal force pushing the tail right to keep it from spinning. If the back rotor of a helicopter malfunctioned it would begin to spin.
The main lifting blades make up the rotor
Just take a hammer and bang on it while spinning the rotor. Keep going until if gives.
It uses the main (top) rotor to remain at the same altitude while using the tail (back) rotor to keep from spinning uncontrolably.
With out a drive shaft spinning in the tranny when the wheels spin if being pulled, u should be okay.
