ANSWER:
Problem C19.3
Why is it necessary to have the tail blade B on the helicopter that spins perpendicular to the spin of the main blade A? Explain your answer using numerical values and an impulse and momentum analysis.
Step by Step Solution
Step 1 of 3
When the speed of the main rotor (A) starts increasing, the helicopter may start lifting off. Due to this regular increasing phenomenon, the speed of the main rotor will be increasing in the same manner.
Since, the change in the angular momentum is always conserved. As the tail blade (B) on the helicopter that spins perpendicular to the spin of the main blade (A). So, after the transfer of the angular impulse, tail rotor (B) will be in the stable or in a steady position. Again change in the further main speed of the rotor (A), this will be in the need of some other amount of angular impulse. The process will go on repeating.
