How do helecopter blades spin so fast?
Helicopter blades operate from a transmission or gearbox immediately under the blades. They have to spin fast to give the helicopter lift. Once they are in the air the blades twist slightly to give forward motion.
How has the helicopter impacted in society in a negative way?
It has crashed into many things and killed many people.
How much can a helicopter pick up?
It depends on the helicopter. The Russian Mil-26 is the largest heavy lifter at the moment, it can lift almost 23 tons. There is one in northern Canada at the moment to lift mining vehicles into a remote, mountainous valley. -The US Army has also used the MIl-26 to recover crashed Chinooks in Afghanistan. It is the only helicopter that can lift a whole Chinook.
Who was the inventor nof the helicopter?
There were many inventors, but Igor Sikorky invented the first practical one
When a helicopter is a stationary the blades on both sides of the rotor give the same lift?
Yes, when a helicopter is stationary, the blades on both sides of the rotor produce equal lift. This is necessary to balance the helicopter and keep it hovering in place. The main rotor provides lift by spinning rapidly and creating an upward force that counteracts gravity.
Do longer blades help a helicopter?
Within reason they do. Designers make a blade of optimum length and chord.
Is it harder to get a helicopter or an airplane license?
Helicopter definitely.
Helicopters are much more expensive to rent for lessons (assuming you can even find one for rent in your area) and burn more fuel per hour.
The act of flying a helicopter is just more demanding mentally.
Most helicopter pilots start with the fixed-wing license first and then move on to helicopters.
ANS 2 - At one of my postings in the RAF, we trained helicopter pilots for the RAF and Royal Navy. -They all had to start having passed the Fixed Wing Course before they were allowed to train on helicopters, and even so, a number of them always flunked the course.
How many helicopters are in a squadron?
Various airforces and armies have different sized squadrons. Usually about 12 aircraft, but not always.
How many types of transport and explain each transport?
There are way too many different types of vehicles that can be explained but the main types are obviously wheeled veichles (cars, bikes and trucks)... There are also the boats
Why does a helicopter has a second rotor on its tail?
To change its direction buddy. It moves its tail left and right and therefore change the face of front panel upto 360 degrees which make it to rotate in nay direct, and top rotate is use to only lift to to rotate.
Where most military helicopters?
The US Navy owns the most military helicopters, about 800 of them. Many are on ships and at Navy bases all over the world
Ideally, not fast at all. A good pilot will land slowly and smoothly
Why are wings sometimes on top of the fuselage?
The higher profile wing is optimized for different missions. Often it is better for shorter range turboprop aircraft (propellers). Many military jets and props use the high wing design to keep their engines clear of debris if they are landing on a rough airfield in a war zone.
What is the advantages of helicopter?
The biggest advantage is being able to land and take-off in a very small space. This is very useful in cases like operating off warships where they may land on a very small and moving space on the rear deck.
