Six - The Boeing CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lift helicopter. Its top speed of 170 knots (196 mph, 315 km/h) was faster than utility and attack helicopters of the 1960s and even many of today. Its primary roles include troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks.

Why do some helicopters have different numbers of blades?
If you mean rotor blades, theoretically, only one (provided it is counterbalanced and moves fast enough). But you'll typically see two or more. Helicopters use more than one because it requires less rotor speed to get the same lift, and it also runs a lower risk of failure in the mechanical systems. Many rotocraft use four or five, and some up to six or seven blades. There are a few helicopters that use two main rotors, and they are counter rotating so that their torque cancels and a tail rotor is not necessary. But the mechanical complexity of these main rotor systems impinges on mechanical reliability.
What are the parts of a windmill?
The simplest part of a windmill are the rotor blades, generator and the shaft. but there are many parts when it comes to wind turbines. hope this helps!
How many poles as salient pole rotor?
'Salient' means 'sticking out', so if the pole sticks up from the rotor shaft, then it is a salient pole machine.
What is the average altitude of helicopter flights?
You don't provide enough information to answer that question specifically but I can give you a few probabilities. The possible range of a helicopter varies greatly with engine size, body size, weather and location. In general commercial helicopters can do from two to four hours in the air with a top speed of from 50 to 200 knots (air speed). This gives you an average range of around 200 miles...but like I said, there are many variables and these numbers can change greatlly. I am referring to the puma helicopter in particular! 1,200 miles or 1,900km for an Apache Attack chopper. 1,952 km, 1,240 miles or1,080 nautical miles : MI-26 Russian heavy lifter 1,216 nm or 1,400 miles or 2,252 km Chinook CH-47
What are the parts of a direct current generator?
there are many parts of a dc generator armature, field coil, yoke, body, rotor and commutator.
How many passengers can a Chinook helicopter hold?
31
Is the shunnok a army helicopter?
Chinook is a helicopter used by many armies and air forces around the world.
How many roter blades can a helicopter have?
6
How many wings does a helicopter have?
Helicopters do not have any wings. Airplanes have wings Helicopter has rotors. A helicopter has at least two sets of rotors. One rotor creates lift ( Main Rotor on the top ) & the other prevents the helicopter from spinning in circles( Tail Rotor).
How many blades does fastest helicopter have?
Helicopters created nowadays generally have 2 or 3 blades. The fastest recorded helicopter has 3 blades. as it revolves more pressure is put forth and therefore the helicopter travels faster
How many blades does a bristow helicopter have?
Bristow has many types of helicopter with, 3, 4 and 5 blade rotors
How many feet away should you remain from a helicopter with rotors in motion?
It is not really about how many feet you are away from it. it is more about where you are standing near it. you can perfectly walk under the blades of a helicopter while in motion. just try not to jump or throw things things in the air. always enter the helicopter from the front of it, not from the back where the tail rotor or tail boom is
How does a helicopter stay in the air?
The source of lift force from the rotor (Rotation of two objects 'blade' creates a lifting force) blades allows the helicopter to stay in one area for extended periods of time. Each rotor blade, whether it is 2 or 7, has the ability to change pitch. This means the blade can rotate so that the nose or leading edge can tilt down or up. If it pitches up, the lift of the blade increases. Collective Controls As the blades rotate it produces lift. The pilot inputs controls that increases the pitch on all the blades at once. All the blades pitch up and produce more lift, so the helicopter rises. Cyclic Controls The pitch of the blades can also be controlled so that the blade pitches UP when it is on one side of the helicopter and pitches DOWN when it is on the other side. As the advancing blade is moving from rear to front, it decreases it Lift. Then as the blade moves to other side, it increases its Lift and pushes the helo through the air. In a simply explanation, this is what causes the helicopter to fly forward. Think of it like someone paddling a canoe. On many helicopters, the input is accomplished through the controls of the Swashplate. Custermen - Worked 11 years at Bell Helicopter.
What happens to the advancing blade of a helicopter?
The "advancing blade" of a helicopter refers to the side of the rotor which moves forward in relation to the fuselage. As each rotor blade makes a full circle around the center, on one side of the swing, it moves forward, and on the opposite side it is moving towards the rear of the helicopter. When the helicopter is moving forward in air, the rotor blades on the advancing side are moving at a higher airspeed than the rotor blades elsewhere. Rotor speed + aircrafts forward airspeed. This results in slightly more lift on that side. Conversely the exact opposite is happening on the other side where you get Rotor speed - aircraft forward airspeed. This creates a tendency for helicopters to want to roll at high airspeed. This is one of the many odd tendencies of rotor aircraft that pilots are constantly adjusting to balance out.
Why was the helicopter invented by Igor Sikorsky?
Igor Sikorsky was one of many helicopter inventors. He was the one who invented a helicopter that used a tail rotor to counteract the thrust of the main rotor, and he was able to build one with a strong enough engine, an efficient enough rotor, and a light enough airframe. So his helicopter became the first successful commercially produced helicopter.
How many rotors does the helicopter have?
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..
How many tons does a Chinook helicopter weigh?
The CH-47F model weighs 23,400 lbs empty. That is 11.7 tons. Other models will have slightly different weights.
