Helicopter FAQs

Lots of people want the globe of helicopters from interest or because they are curious about ways to enter the hobby of owning and flying a helicopter. There are lots of concerns about helicopters for sale and how to make a license to fly a helicopter.

"How Many Propellers Do Helicopters Have?".

Many helicopters have a solitary primary rotor and a tail rotor. This is the design that Igor Sikorsky settled on for his standard helicopter design that is still being used today. Most all helicopters are developed around this standard design.

"Why More Than One Rotor?".

The rotor system on a helicopter generates lift. The tail rotor produces thrust. The rotor consists of a mast, hub and rotor blades. The mast is a cylindrical metal shaft which extends up-wards and is driven by the transmission. At the top of the mast is the attachment point for the blades and is called the hub. There are 3 fundamental classifications for the rotor cutters. These include: semi rigid, stiff, or completely articulated.

"How Does A Helicopter Fly?".

The two flight conditions for the helicopter are the hover and forward air travel. Floating is the most difficult part of flying a helicopter. In this position the helicopter remains in a fixed position managed by the pilot. In forward air travel the helicopter is similar to a standard aircraft.

"Which is Much better - Helicopters or Plane?".

The major restriction of the helicopter is rate. It will not fly as fast as a winged plane. If airspeed is something you are concerned about then the helicopter is not an airplane you would want to buy. If on the other hand you are interested in an airplane with flexibility to land in small areas then the helicopter might be exactly what you are trying to find in an aircraft.

"How Did The Helicopter Evolve In time?".

It was not until 1942 that the helicopter was put into complete scale manufacturing. That year there was 131 helicopters constructed. This actually started the contemporary history of the helicopter. They were placed into military operations virtually immediately because of the flexibility of the plane. They could be made use of for offensive operations and protective operations also. They also were made use of for medical emergencies and troop transport.

They ultimately became a major part of numerous military operations and fights. They showed specifically shown efficient in jungle conditions like Viet Nam. Probably the most historical pictures and tales of helicopters in military operations were released during the Viet Nam War era. The famous Black Hawk helicopter was the topic of lots of flicks, posts, and books as well.

Military History is full of recorded events and the operations of helicopters. Noncombatant usage of the helicopter now dominates the information and using the helicopter. However, the military today still makes use of the helicopter in every branch of the armed services. It is an important link for the military and its operations in war time and peace time.
