It varies for all blades collectively as you pull up or push down on the collective. and alternates from side-to-side and front-to back as you move the cyclic. If you move the cyclicto the right it decreases the angle of attack on the right side and increases the angle of attack on the left side. Since the right side loses lift and the left side gains lift the helicopter will bank and turn to the right.
The angle of attack of all the blades at hover will be about zero.

What is blade pitch of a helicopter?
The angle of the rotor blades.
What increases the thrust of an helicopter?
The 'angle of incidence ' of the rotor blades and blade speed.
How can you make a helicopter move forward?
The blade pitch , or angle , is tilted forward through the rotor head .
What is a blade from a helicopter in words?
The main blade on a helicopter is the 'rotor'
Why as density altitude increase reduce speed of helicopter?
To compensate for the decreased air density the rotor blades need a greater angle of attack, pushing the retreating blade closer to stall(reducing the maximum airspeed)
Why helicopter speed reduce as increase altitude?
Because as you increase altitude, the density of air decreases. To compensate for the decreased air density the rotor blades need a greater angle of attack, pushing the retreating blade closer to stall(reducing the maximum airspeed)
Why do helicopters make noise?
The source of the noise made by Helicopters are created by several things. The engines can make noise just like any airplane. The transmissions can make a high frequency noise. The destinctive sound of helicopters is the "whop-whop-whop" it makes. This is caused by the rotor blades as it rotates.One reason for this sound is one blade passes and creates a vortex(or whirling tunnel of air) and then the next blade slaps this vortex.Another reason is that each blade must change pitch angle as it rotates around the central mast. When the blade is on one side of the helicopter, it has a high pitch and creates a high lift and therefore a large turbulent vortex. Then as it rotates to the other side of the helicopter, the blade must decrease its pitch angle, sometimes to almost zero angle. This rapid change in high blade angle and low angle causes this blade sounds.newtest3
What happens when the blade of a helicopter stops spinning in the sky?
Then the helicopter will crash.
What is the best angle for an air propeller?
The best "angle of attack" for a propeller depends on many factors, the main ones being: the speed of airflow over the blade; the distance along the blade from the centre of revolution; the physical dimensions of the blade; the density of the air which it is trying to pull, or to push, to produce the force called "thrust" which drives the blade, and the aircraft attached to it, through the air. That is why the blade does not have a simple flat surface, but one which has many angles of attack along the blade due to the complicated shape of the blade.
What is palindrome for a blade of a helicopter?
rotor
What is a helicopter blade held on with?
Helicopter Blades are bolted onto the main rotor
How many people can fit in anApache helicopter?
The AH-64 Apache is a 4-blade, twin-engine is an attack military helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew.
