Some helicopters have on rotor on a horizontal axis perpendicular to the helicopter body at the tail Why is a single rotor never used?

because the spinning motion of the main rotor crates a force called torque, with makes the helicopter's body want to spin in the opposite direction. The tail rotor is used to create anti-torque and stop the body from spinning. In the cockpit, the pilot will use anti-torque pedals which change the angle that the tail-rotor's are spinning at. Allowing the body to spin slightly means it can change direction, and forcing it to spin more in the opposite direction allows it to turn (or yaw) the other way.
A single rotor helicopter will spin uncontrollably in the air and will possibly not take off at all.

Are there any helicopters that can dump fuel?
yes there are helicopters which can dump fuel. the most basic helicopter allouette ( the french single engine helicopter) has a capability of jettisoning fuel at the rate of 130 lts per hr.
How big a helicopter is?
They are all sizes from microlight single seaters to huge helicopters that lift 20 tons or more.
Why does a typical small helicopter with a single rotor have a second small rotor on its tail?
All helicopters have a tail rotor to stabilise them.
Why is a single rotor never used on helicopters?
In helicopter terms, the Rotor is actually the set of blades as a whole, individual blades are termed to be the rotor blades. So if you negate the Chinook, and a few other unusual types of helicopter, all helicopters utilise a single rotor. If you mean a single rotor blade, well again a single rotor blade design has been used on a helicopter.... An example of this was the Hiller HJ-1 Hornet, also the Boelkow 101/103 are good examples of this design.
How can i rent a helicopter?
If we want to travel on a flight or in a helicopter we just book our tickets through an agency. Like the same, we can easily rent helicopters for any use with the help of an air charter company. There are many air charter companies working for helicopter charter. Helicopters are widely used for events, marriage, short sight seeing etc. You can rent any type of helicopters if it is twin engine or single engine helicopter at any time anywhere. You can use helicopters at the place which doesn't have a runway because helicopters need small space to land. Helicopters used in many events like inauguration ceremony. Different types of helicopters as you wish will arrange by the air charters. Many hotels using helicopters for sightseeing purpose for their customers. The helicopter is easy for sightseeing than flights. Today's you easily rent any type of helicopters with the help of air charters.
Is any horizontal line perpendicular to any vertical line?
Yes, but only if they are exactly vertical and exactly horizontal (90 degrees angular difference). For real-world examples, many vertical lines can be perpendicular to a single "horizontal" curved line at the points of intersection.
How many cylinders does the R22 helicopter engine have?
The Robinson 22 helicopter has a four cylinder pistol engine. The single-engine light utility helicopter was designed in 1973 and has been in production since 1979. The cost of one of these helicopters is about $270,000.
How many engines does a helicopter have?
Depends on the class of helicopter and its function. Your smallest helicopters will only have one, whereas your medium helicopters may have either one or two. For example, single and twin engine variants of the UH-1 helicopter were manufactured. Two really tends to be a bit more common in this size range. Some even have three, such as the CH-53.
Who invented helicopters and when?
Juan de la Cierva.1/9/1923....110.HP. Piston type,SINGLE ENGINEPaul Cornu, 1907, France.Igor sikorsky invented helicopter.
Why doesnt a helicopter Spin out of control?
Most helicopters have a tail rotor for stability while others (often Russian military helicopters) have two main rotors. In both cases the two rotors spin in opposite directions, in order to cancel out any torque effect of a single rotor.
Who invented the Helicopter and successfully flew it?
No single person "invented" the helicopter. Like all complicated machines it was developed over a period of years and many people tried different things. The Germans had simple but unreliable helicopters in the 1930's and none got beyond prototype stage. There were also many Autogyros in the '30s , but they weren't really helicopters as the rotors were not powered. - In my opinion the first person to build and fly a successful helicopter was Igor Sikorsky around 1940.
Why was the helicopter invented?
You can rather seek who invented the helicopter, the first successful one.Igor Sikorsky is considered to be the "father" of helicopters not because he invented the first. He is called that because he invented the first successful helicopter, upon which further designs were based. hi there mateOne of aviation's greatest designers, Russian born Igor Sikorsky began work on helicopters as early as 1910. By 1940, Igor Sikorsky's successful VS-300 had become the model for all modern single-rotor helicopters. He also designed and built the first military helicopter, XR-4, which he delivered to Colonel Franklin Gregory of the U.S. Army.Igor Sikorsky's helicopters had the control to fly safely forwards and backwards, up and down, and sideways. In 1958, Igor Sikorsky's rotorcraft company made the world's first helicopter that had a boat hull and could land and takeoff from water. It could also float on the water.I got this fromhttp://inventors.about.com/od/hstartinventions/a/helicopter.htm
