Helicopters
A helicopter is an aircraft which is propelled and lifted in the air by one or more large horizontal rotors. Focke-Wulf Fw 61 was the first operational helicopter manufactured by Focke-Achgelis in 1936.

Would a helicopter work on mars?
A helicopter could potentially work on Mars, but it would face significant challenges due to the planet's thin atmosphere, which is about 1% the density of Earth's. This low density means that rotor blades would need to be larger or spin faster to generate enough lift. NASA's Ingenuity helicopter demonstrated this concept by successfully flying on Mars in 2021, proving that powered flight is possible, albeit with specialized engineering adaptations. However, sustained operations would require careful design to handle the Martian environment and atmospheric conditions.
yes, they do. China arms many countries with the intention of disturbing Western power
What part makes a helicopter reverse and picture of it?
There are two controls on a helicopter that adjust the rotor blades: the cyclic and the collective.
- The cyclic control tilts the rotor blades cyclically so that those on one side of the rotor tilt more while those on the other side tilt less, the result is to tilt the entire rotor disk in a particular direction, resulting in the helicopter moving in that direction. If the pilot pushes the cyclic control in a given direction, the rotor disk tilts in that direction, and produces a thrust vector in that direction, resulting in movement in that direction.
- The collective control tilts all the rotor blades collectively (i.e. all at the same time) and by the same amount, the result is the helicopter increases or decreases its total lift derived from the rotor. In level flight this would cause a climb or descent, while with the helicopter pitched in a given direction an increase in total lift would produce an acceleration together with a given amount of ascent.
Why does a helicopter engine to stall during an ash storm?
Almost any aircraft egine will stall if ingesting ash instead of clean air. Clean air is essential to an engine's performance
How long is an average helicopter?
What would you call "average". I don't see there is an "average" helicopter, all are different.
How do you use the magnet under the helicopter man in Happy Wheels?
In Happy Wheels, the magnet under the helicopter man is used to attract or repel objects in the environment. To utilize the magnet effectively, you simply need to control the helicopter man and activate the magnet by pressing the appropriate key (usually the space bar). This can help you navigate obstacles or manipulate items to clear a path. Timing and positioning are key to using the magnet successfully.
How fast can a helicopters go?
Some experimental helicopters can fly as fast as 300 mph. However most helicopters in service fly less than 200 mph.
Why are some helicopter rotors enclosed?
Rotors are never enclosed. The control propellor is sometimes enclosed because the designer feels it is safer and more aerodynamic.
What are some advantages of helicopters rather than airplanes?
Helicopters can land where airplanes cannot.
What are the advantages of helicopters over airplanes?
Helicopters can land on small ships, clearings in forest, on top of buildings etc. Airplanes can not do these things
What is the name of the twin propeller helicopter?
there are a few twin rotor helicopters. The Chinook is possibly most famous.
How much money does it cost to buy helicopter?
Even a cheap civilian helicopter is well over 3 million dollars
How many engine does the helicopter bell 212 have?
The Bell 212 has 2 PT-6 turbine engines. This was basically the ultimate Huey, designed for the Canadian Forces in the late 1960's.
Why was the helicopter and important invention?
Helicopters were an important military invention because they enabled direct air transport without needing a runway. They were thus able to act as transports for the wounded in the Korean war and later in Vietnam from the front line directly to military emergency hospitals. This undoubtedly saved the lives of thousands of injured soldiers. ( The TV series 'MASH' is a great depiction of this ) .
In Vietnam helicopters were more advanced and by then used to land troops in front line locations and in jungle and hilly areas where fixed wing aircraft could not operate. By the end of Vietnam helicopters were also acting in an assault role, able to operate in areas where jet fighters were relatively useless.
In civilian use helicopters became rescue machines for shipping and very useful in many aspects of construction such as helping with erecting power pylons, logging and fire-fighting.
Where are helicopters parked on the runway?
They are never parked on the runway . They park on taxiways designated for parking.
Why is a helicopters propeller sharp?
Helicopters propellers are not 'sharp' . They are aero-dynamically shaped.
