rotor
What is palindrome for a blade of a helicopter?
rotor
What is the palindrome for system of horizontal blades that allow helicopters to fly?
Rotor blades
What is the airfoil on a helicopter?
The rotor blade is the airfoil on helicopters.
Are there any 3 blade rotor helicopters in use?
Yes, many small helicopters have 3 blades
Why a helicopter chopper?
Q: Why is a helicopter called a "Chopper"? A: I think the names comes from the sound of the blades make: whop-whop or chop-chop. FYI, the helicopters that have the loud popping of the blades are usually a 2-blade of the Bell Helicopter design. The multi-blade helicopters do not have a sound as distinctive as the Bell helicopters. The sound comes from the blade striking the vortex generated by the blade ahead of it.
What is a blade from a helicopter?
It is the major part of the rotor. Helicopters can have 3 up to 8 blades on a rotor.

How fast will the helicopters go in the future?
Not much faster. True helicopters are limited in airspeed. The helicopter blade can not fly faster than the speed of sound or it begins to flutter and even stall. The advancing blade has to go through the air faster than the retreating blade. The speed of the blade is the sum of the speed of the helicopter in forward flight plus(+) the rotational speed of the turning blades. If they can design a blade that will work at slow speeds and at speeds greater than Mach 1, then maybe they can build a faster helicopter.
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
Why do helicopters always have two sets of blades?
The upper set, the rotor, provides lift. The smaller blade at the rear provides steering .
