Helicopters Frequently Asked Questions

By Prett White


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?".

The majority of helicopters have a single primary rotor and a tail rotor. This is the design that Igor Sikorsky chose for his standard helicopter design that is still being made use of today. The majority of all helicopters are built around this basic 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.

"Exactly 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 primary restriction of the helicopter is speed. It will not fly as fast as a winged airplane. If airspeed is something you are worried about then the helicopter is not a plane you would want to buy. If on the other hand you want an aircraft with flexibility to land in small locations then the helicopter might be exactly what you are looking for in an aircraft.

"Exactly 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 many military operations and fights. They showed especially shown effective in jungle conditions like Viet Nam. Probably the most historic pictures and stories of helicopters in military operations were released during the Viet Nam War age. The well-known Black Hawk helicopter was the topic of many movies, posts, and publications 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.
