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.
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.
They are all sizes from microlight single seaters to huge helicopters that lift 20 tons or more.
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.
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.
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.
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.
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.
Igor Sikorsky is credited with designing and building several helicopters throughout his career. Notably, he created the VS-300, which was one of the first successful single-rotor helicopters, and the R-4, the first helicopter to enter production in the U.S. While the exact number of helicopters he designed varies, Sikorsky's contributions significantly advanced helicopter technology and paved the way for future developments in the field.
The invention of modern helicopters is primarily attributed to Igor Sikorsky, who developed the first successful single-rotor helicopter, the VS-300, in 1939. Sikorsky's design included a tail rotor for stability and control, which became a standard feature in later helicopters. His innovations laid the groundwork for the development of modern rotary-wing aircraft, making him a key figure in helicopter aviation history.

The MD 530F is a versatile single turbine helicopter with a Rolls-Royce 250-C30 engine, capable of high performance in high-altitude and high-temperature conditions, a maximum range of 230 nautical miles, and enhanced lift capacity.
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.
