That is the Chinook.
Helicopter can have 2 blade, 4 Blade, 6 Blade, 8 Blades. Selection of this Blades depends up on the Power Rating. For a small 2 Ton H/C, it can have 2 Blades. 5 Ton H/C can have 4 Blades etc..
Undetermined. All helicopters have 2 rotors; usually a Main Rotor and a Tail Rotor. So, I assume you meant 2 Main Rotors of same diameter.Boeing Ch-47 Chinook - One rotor mounted in the front over the cockpit and one rotor in the rear.V-22 Osprey - Both rotors are mounted on engine pods mounted at the tips of the wings. The engines rotate from helicopter mode to airplane mode. This helicopter just went into operational service after years of development.There are helicopters with no tail rotor. It has two rotors on top. One going clockwise the other going counter clockwise. Called Coaxial rotors or co-rotors are a pair of helicopter rotors mounted one above the other on concentric shafts. The military ones look like jets so even with jet engines. Very nasty looking helicopters.They are much faster and can turn and maneuver much faster. You can look it up. Helicopters with Coaxial rotors. I do not mean the ones with the fan in the tail. These just have wings on the tail.The other one is the NOTAR is the name of a helicopter anti-torque system which replaces the use of a tail rotor. Developed by McDonnell Douglas Helicopter Systems (through their acquisition of Hughes Helicopters), the name is an acronym derived from the phrase no tail rotor but uses air to keep the copter from spinning.
Well, it would be worth about 2 million dollars, my husband is manager of a helicopter company and goes to India a lot.
That is a twin rotor helicopter
It depends on the vehicle. If it has 4 wheel disk brakes it has 4, others have 2 rotors & 2 drums.
( 2 rotors on the front ) one for each DISC brake
2 or 4
No
About 30 each for rotors and 2 hours (or less) in labour.
Remove wheels Remove 2 caliper mounting bolts Slide caliper off rotors Rotors should slide off hub

The largest RC helicopter in the world is the CH-47 Chinook twin turbine, measuring over 9 feet in length and with a rotor diameter of around 6.6 feet. It is a detailed and scaled-down replica of the real-life CH-47 Chinook helicopter.
