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.

How fast does a C130 airplane fly?

A C130J flys at 417mph top speed and about 400mph at cruising speed

How does a helicopter fly backwards forwards and sideways?

move the cyclic control the direction you want to move.

How much gas does a helicopter need?

A commercial helicopter can hold up to 200 gallons of fuel. How much it needs to run depends on how far the trip is and depends on how much weight it is carrying in passengers, luggage/freight, plus pilot / co-pilot.

Main use for helicopters?

it is mostly used for trasportation and othere stuff like moveing objects and military helicopters are used in combat as releaf,resupplyingm,scouting,pre-battle pot shots..etc this has been posted by the anounymous organization for more info on anounymous go to 4chan or 7chan

Where is James Gavin the Helicopter Pilot?

My parents were close friends of jim.Him and my father flew together . He died in 2005.

What are the Dangers of helicopter taking off from mountain or hilltop?

Mountains are high up in the air, and the higher up in the air one is, the less dense the air is and stronger the wind is. These two factors can affect how well a helicopter can take off. The stronger the wind, the more likely the helicopter is to be pushed into something and crash or be pulled off the land before it has enough lift to support itself. This is one of the reasons for park rangers not to come save you if you fall down some steep glaciers. The less dense the air, the harder it is to get enough lift to support yourself. It also makes breathing harder (less oxygen per breath). As for hilltops, I'm not entirely sure what dangers there are. I suppose it depends on how high the top is.

Travel distance of a bell 412 helicopter?

Per the company website, it is anywhere from 356 nautical miles to 659NM based on weight.

What do you call the place where helicopter lands?

A "helipad" is a helicopter landing pad. The helipad provides a clearly marked hard surface away from obstacles for the helicopter to land.

Why are helicopters so hard to fly?

Hard compared to what? It's all about learning. I can fly a rotary aircraft but can't fly a fixed wing to save my life. There's a big difference in the overall feel of the aircraft.

What is the windshield of a Helicopter made of?

Most helicopters use acrylic glass (also called plexiglass) for for the windshield because of its light weight. Acrylic glass is very easy to scratch however, and so the windshield may need to be replaced several times through the lifetime of the aircraft.

When and where were helicopters invented?

The first successful airplane took off in 1903 in North Carolina.

The first successful helicopter that could safely be controlled in turns, hovering and level flight was developed by Igor Sikorsky in the 1940's.
The first helicopter might be built in Ukraine (1909) by Ukranian engineer Igor Sikorsky (1889 - 1972) but it was more than 25 years before early practical machines - like the VS-300 were flown in prewar trials.

Can you fly a helicopter to Jamaica?

Yes, your typical civilian Jet Ranger helicopter has a range of well over 300 nautical miles. Well enough range to island-hop down to Jamaica.

However, the top speed is somewhere around 130mph, pretty slow for an aircraft... It will be a long flight.

The first modern helicopter?

The first modern stable helicopter to perform all the roles a modern helicopter can perform was the German Flettner FL 265. It first flew in 1939 and had an enclosed canopy, undercarriage, synchropter rotor configuration that had zero torque problems, was easy to fly, could perform air sea rescue and take off and land from ships at sea, could take off, hover, fly forwards, backwards, sideways and was the first modern helicopter to transition from forward flight into autorotation and back again. Later helicopters based on it's configuration include the world first production helicopter, the Flettner Fl 282, the American Karman Huskie and Karman K-max heavy lift chopper. The Flettner demonstrated all these abilities before Sikorsky first flew his less stable and more primitive Vs-300 The Fl 265 was not the first successful helicopter however and earlier craft performed well such as the FW-61 famous for flying indoors in front of crowds and setting distance and altitude records, and earlier craft such as the single main rotorFlettner Fl 185, French Dorand Breuget etc all were capable of vertical take off and hover. http://www.youtube.com/watch?v=64fgG2CnHn0 http://www.aviastar.org/helicopters_eng/flettner-265.php http://www.aviastar.org/foto/gallery/flettner/flettner_kolibri_3.jpg

Why is it called a Chinook?

The US Army gave Indian tribal names to all of their helicopter models. Such as: Cheyenne, Kiowa, Cayuse, and the Army's latest UH-72A "Lakota". Chinook is another name of an Indian tribe.

How do you fly helicopters?

With a cyclic stick, collective stick, throttle, and tail pedals. These are the basics.

The collective stick is positioned like an emergency brake in a car. By pulling up on the stick increases the angle of attack (pitch) of all the blades on the main rotor and causes lift. This allows strictly up and down movement. In order to move forward for example, the pilot pushes forward on the cyclic stick (between his legs) which increases the pitch of the main rotor blades but only as they travel through the rear arc of rotor path. This causes more lift at the rear of the helicopter which now directs the air down and rearward. This will cause a drop in lift due the the re-directed air which is compensated by adding more collective. The tail rotor is controlled by the foot pedals. To rotate or bank left, press down on the left pedal and the opposite for right. When flying forward while banking left or right requires a delicate balance of all 3 main controls. Collective, cyclic and tail rotor. The throttle is usually set during flight and unlike a plane, the throttle isn't manipulated to cause the helicopter to climb or speed up. This is achieved by manipulating the pitch of both the main and tail rotors.

Can the throttle engine power of a helicopter be used interchangedly with the collective?

Not exactly. The collective is actually linked to the throttle, so that pulling up on the collective will also open the throttle more, as ascending requires more power. The link between the collective and the throttle reduces variations in engine RPM. The throttle control on the end of the collective is typically only used to make small adjustments during flight. Hope I've got this right, and that this adequately answers your question.

Can gasoline be used to replace jet fuel?

No, "jet fuel" refers to a set of fuels used in gas turbine engines (GTE).

Gasoline would burn far too hot in a GTE, eventually damaging the engine.

Jet fuel is a lot closer in nature to Diesel, Parafin or Kerosene

Why do some helicopters have enclosed tail rotors?

An enclosed tail rotor is safer and resistant to fouling.
