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.

Yes they do. By pulling back on the cyclic stick the main rotor swings backwards forcing the helicopters to go backwards. -Credits Lukespill
How does a helicopter move forward?
When the stick is moved by the pilot, it moves an assembly called a swashplate accordingly. The swashplate is at the rotor base. When this moves, it changes the pitch of the rotor blades. As the pitch changes, the orientation of lift produced changes as well. Thus, when the stick is moved forward, the blade pitch is affected by the swashplate to re-orient the lift forward, instead of directly vertical, and the helicoptor is pulled in a forward direction.
The black box is usually orange so it is easy to recover if the helicopter or plane crashes
What are the different types of helicopters?
All US helicopters are advanced modernized versions (or descendents) of the Vietnam War era choppers:
1. CH-53 Sea Stallion (CH=Cargo helicopter)
2. AH-1 Cobra (AH=Attack Helicopter)
3. UH-1 Iroquois (the Huey/UH=Utility Helicopter)
4. HH Jolly Green Giants (HH=Heavy left Helicopter)
5. OH-58 Kiowa (Observation Helicopter/jet ranger)
6. OH-6 Cayuse (Observation Helicopter/this bird actually was designed to replace the US Army's O-1 Bird Dog artillery observation airplane; used for the last time in Vietnam).
How big is a helicopter rotor's diameter?
It is different with every helicopter. For example, the Blackhawk rotor is 53 ft 8 inch in diameter.
Where did the word 'helicopter' originate from?
The word, helicopter, originates from the French word, helicoptere.
Do helicopters have a reserve tank?
aircraft dont have "reserve" tanks - aircraft usually have more than one tank and they are all used - reserve fuel refers to always keeping 45 minutes of fuel in reserve for emergancies or in case a plane needs to remain in the traffic pattern for a long time waiting to land - any tank can be the one holding the 45 minute reserve or can be more than one since aircraft fuel gauges are very inaccurate fuel use is calculated before each flight and the 45 minute reserve is worked into the flight planning The fuel tanks are generally referred to as Main and Auxiliary. The Mains will have the pumps to get fuel to the engines and the Aux will be used to carry the extra fuel to hopefully complete the flight and has transfer pumps to move that fuel to the Mains.
Who was the first person to ride in a helicopter?
According to the most recent archives received from the National Aircraft Database, Joe Jonas was the first man ever to fly in a helicopter. (Interesting Fact: Does the name seem familiar to you? The new teenage popstar Joe Jonas from the Jonas brothers was named after him.)
By increasing or decreasing the speed of the tail rotors. This unbalances the torques acting on the helicopter and causes it to spin.
Diagram of a Helicopter engine?
Helicopter engines vary from one another. The mayority use turboshaft engines. But you can take a look at this web site: http://www.howstuffworks.com/framed.htm?parent=apache-helicopter.htm&url=http://www.geae.com/engines/military/t700/t700-701c.html
I believe the FAI world altitude record for a helicopter is 40820', and helicopters can now land on the top of Mount Everest, just over 29,000'. But practically speaking, helicopters rarely go over 10,000 feet as that's the altitude above which pressurized cabins and supplemental oxygen are required.
What powers a helicopters rotor?
An engine usually more than one which is connected to a main driveshaft then that is connected to a C-box or Combining gear box which connects to a transmission which turns the rotors.
Helicopter has impacted society in many ways (depending on the uses) because of its special hability that airplanes does not have, which is vertical take off, and landing: * Transportation: They make transportation (passengers and cargo mostly) easier, faster, and somehow safetier than some other kinds. This is primarely the reason #1 why they have impacted our society. * Media: The press use helicopters for particular purposes, mainly to take a look at the freeway congestions. * SecurityHaving a helicopter in the sky means a great advantage because you can cover much more sighting than being just on land. So the police uses Helicopters to follow suspects. In that way it would be much harder for them to scape. * Rescue/ Evacuation Sometimes an ambulance just can't get on time where it needs to be. A helicopter on the other hand, gets faster wherever you need it because it doesn't has to deal with the obstacules a car would face (like walls, rivers, forests, etc...), and where airplanes would crash easily. So having a helicopter as an ambulance, it could save a live that other wise would be lost with another kind of transportation. When a person gets lost in the wild (mountains, oceans,etc), a helicopter is generally the best way to star the research. Sometimes when a disaster happens (floods mainly), the only way to get into the place it's by helicopter. * Fire countrol As a firefighter, you need two things to extinguish a fire: time and water (well you can use other things). But sometimes those two are tighltly limited with fire trucks. Helicopters can make it all the way faster and carring much more water than a fire truck could. So it represents a great advantage for firefighters. * Federal Forces Techniques/ Strategies The Army/Navy could use helicopters for a bunch of different things. For example: They could armed a helicopter with anti-artillery equipment, and destroy enemy foreces, thus, clearing the area (or help to) to allow allied forces come by. Or they could use helicopters for extraction operations. And many others, too. * Others: * Movie film * personal transportation * specialized business: tours and related sutff * aerial cranes * just for fun. * And surely much more.
like these examples mentioned above, helicopters had impacted people's lives dramatically, forever. for more detailed information you can visit wikipedia: helicopters
When a helicopter is on the ground can it leak fuel?
That is possible but no greater than in any aircraft.
Who designed a helicopter before one was invented?
In 1500's, Italian inventor Leonardo Da Vinci made drawings of a flying machine.
Who invented the helicopter in 1936?
The first transverse twin rotor helicopter was invented in 1936.The Focke-Wulf Fw 61 was invented by Heinrich Focke and flew on 26 Jun 1936.
What is the name of the helicopter with two propellers used to carry supplies?
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.
When was the first modern helicopter invented?
The very first piloted helicopter was invented by Paul Cornu in 1907, but this design didn't work. Later, a Frenchman Etienne Oehmichen built and flew a helicopter 1 km in 1924. An earlier practical helicopter that flew for a decent amount of space was the "German Focke-Wulf Fw 61."
How much does a helicopter weigh?
A helicopter...a real one that is....can weigh as little as 1300 to 1600 pounds for a 2 place piston, like a Robinson R22 ( guessing the weight) to a BK 117 like I fly which grosses out at 3200 Kgs to the huge Russian machines that are up to over 100,000Kgs. The Mil V-12 is the largest I believe. Whatever their weight they are sure to consume huge amounts of fuel whatever they do.
