Q.1 - What will be the direction of the angular acceleration caused due to change in angular velocity of the rotor [as it changed direction] ?
Q.2 - What will be the direction of the active gyroscopic torque and how to determine its direction ?
Can its direction be determined by the direction of angular acceleration as well as by the direction of the force applied to change the direction of motion of the plane ? Are both results same ? why ?
thnx for your support .. :)A problem about gyroscopic effect in an aeroplane .?if you are talking of a helicopter, the rotor is not rotating in the clockwise direction, the rotor of a helicopter moves in the anitclockwise direction and the left and right motion (change in direction) is done by the action of the tail rotor (increasing or decrasing the pitch angle of the tail rotor). no external torsion force is applied in a helicopter, (it is possible only in fixed wing aircrafts). direction change has nothing to do with main rotor, consider the helocopter is hovering, the change in direction of the nose dosnt change the parameters of main rotor as the wind is flowing from top to bottom. the tail rotor is used to nullify the effect of newtons third law of motion. (as the main rotor rotates, the body tends to move opposite to it.). The rotor can be divided to two halves, advancing half(the right hand side of the rotor disc) and retreating half. the advancing half have a blade velocity much greater than retreating half. please consider these parameters.A problem about gyroscopic effect in an aeroplane .?@ nithin
really , thank you for answering .. bt as i asked .. my problem is not about any specific real situation. i am asking to assume the situation [as mentioned in my question] , whether it's practically correct or not . the main problem is about the gyroscopic torque direction . please clear my doubt about this .. :)
