Helicopters

In warfare a helicopter is like a sitting duck. The jets will just blow the crap out of 'em cause an air-to-air missle is faster, way faster than a helicopter.

Igor sikorsky invented the helicopter he also died on october 26, 1972 and born on may 25, 1889

Most large aircraft that have turbine-powerd engines use a fuel called Jet A. Jet A is basically highly refined kerosene. Jet A is used in the United States, Jet A-1 is used in the rest of the world. Where extreme cold conditions exist, Jet B is used for its better cold weather performance.

Other aircraft that have reciprocating (piston) engines use Aviation gasoline, which is similar to what is used in automobiles.

Main rotor and tail rotor. The main rotor is on top of the helicopter consisting of two or more blades, and the tail rotor is at the back of the helicopter, which also consists of two or more blades.

McDonnell Douglas

There are at least 200 in Inida- Morgan Holland

1. Hover.

2. Take-off and land vertically.

Although there are airplanes (such as the Harrier) which can do these things.

The Robinson R22 costs about $300,000. The new CH 53 K as ordered by USMC costs about 26 million

Black boxes of any aeroplane are mostly Orange in color.

The average Blackhawk carries 360 gallons of fuel internally . Some versions may differ.

Igor Sikorski was an aircraft designer in Russia. But he came to the US and began to build helicopters. Many of his helicopter designs were used in the military. In 1943, Larry Bell who owned Bell Aerospace was convinced of a helicopter design after seeing a remote controlled model built and flown by Arthur Young. Bell set-up a design shop in Garden Park, NY where the first Bell Helicopter was built. This prototype evolved to become the Bell Model 47---the first helicopter to receive FAA Certification.

Rotors, they are generally so-called (Props) applies to conventional propellers on conventonal aircraft, of course an autogyro or a Rotordyne has both propellers and Rotors but that is a special case.

The Korean war was the first time Vertical Envelopment was used, or the use of helicopters to assist troops in battle.

Yes. Quite easily.

turbine helicopters take either JP-4 or JP-5 grade jet fuel.

It depends on the type of engine. Prop planes use AvGas - aviation gasoline; essentially this is high power petrol, equivalent to 6*. Jet engines use a variety of kerosene mixtures.

To start learning you need to be 16 years old but to do the tests and acquire a licence you need to be 17 years old (US).
You have to be at least 20 if you want to be safe, but usually you have to be 18.

The first practical true helicopter was developed by Igor Sikorsky (naturalized White Russian) about l940 or 4l. they had minimal use in the conflict as they were pre-occupied with getting the technical bugs out. There were a very few used by the Navy very late in the war as air-sea rescue craft for ditched carrier crews! They were ideally suited to this role.-and still are. There were other helicopters such as that of Paul Cornu (French) in l907, Breguet (better known for conventional aircraft and watches) and such composites as the compound autogyro which was flown inside a stadium by the German Aviatrix Hanna Reitsch in l933. this craft , which had counter-rotating rotors was not, strictly speaking, a helicopter but (Showed the way). Craft was the Focke-Aghelis FA6l as I recall and had the serial number D-EKRA . In early 1940's, Arthur Young demonstrated a remote-controlled flying helicopter to Arthur Bell, the owner of Bell Aircraft. Mr. Bell set aside a facility at Garden Grove, NY, to build a prototype based upon the model. This prototype became the Bell Model 30 and a commericial version called the Model 47 became the first commericial helipcopter built for private use.

Yes, by changing the rotor angle.

Igor Sikorsky invented the helicopter.

Which helicopter pilots?

Yes! If routine maintenance is performed and the airframe properly maintained these aircraft are among the safest conveyances available for transportation, heavy lifting, miltary operations, and public safety operations in the air today. A helicopter has one great advantage over fixed wing aircraft landing in an emergency. The manuever is called an Autorotation, a term used to describe the parachute like effect caused by engaging the main rotor's blades after dropping from the sky during an emergency allowing crew and craft to escape unharmed. Please remember that the helicopter is the most widely used air rescue vehicle in the world and that accidents are often the result of responding to adverse life threatening situations rather than the aircraft or the pilot. Now go get yourself some lessons and see what it's like to be free. Attitude 26fsak!
