Helicopters

all of the lift- and propulsive thrust comes from the rotors. therefore they cannot in any sense fly as fast as jets. I do not think a true helicopter, as opposed to a stub-winged thing like a Rotordyne could go much above 200 MPH. Probably some jet-boosted experimental models have gone faster, but these are not standard issue models.

Most versions of the Puma can attain about 160 mph.

The Marines use the AH-1Z Viper which is a variant of the AH-1 Cobra attack helicopter. It packs a 3-barreled 20mm Gatling Gun in the chin turret, hardpoints for 16 Hellfire laser-guided missiles and two Sidewinder air-to-air missiles on the wingtips.

Bell have made many helicopters, we need a name or model #

This phrase was written on the lyric booklet that came with Seattle post-hardcore band the Blood Brothers' fourth studio album "Crimes." The album was released in 2004.

A helicopter can weigh anywhere from 1370 pounds for a very small (Robinson R22 Beta II) to over 33,300 pounds (Sikorsky CH-53K). ~ The Robinson R22 Beta II can lift around 400 pounds and has 131 hp.

~ The Sikorsky Ch-53K can lift over 36,000 punds and has 18,436 hp.

You get your threat high, and a Police Copter will come. If you keep killing, a Stealth Copter will come. to get the News chopper, go on the mission "Put to the Test", Autobots; or "Hazing", Decepticons. Instead of going through the tunnel, climb the building. when you get onto the roof, you ought to find a pool, beside the pool rests the News Chopper. Scan away!

Helicopters were not used in World War 1. And they were just being designed in World War 2. It wasn't until the Korean War that the Helo was used.

Yes, and not only as military equipment.- if it wasnt for helicopters, hundreds of thousands of people would not be alive today with things such as - Search and rescue helicopters Firefighting helicopters Air ambulances (medEvac) Coast guard helicopters the reality is that helicopters are vital in our modern world

Bigger, faster, capable of lifting greater weights and capable of flying at higher altitudes.they areused for bobingghjkshbnfvdshfourd

Basically, the body, the engines, and the blades. Helicopters vary greatly from one another, so what could they be made of depends on the company and kind.

African Americans use the same thing as everyone else as transportation. Depending on the time period you are referring to that could be horse, train, car, plane, boat, or any other of the modes of trans portion available at that time period. Being African American was not a factor.

It is the main rotor of a helicopter that acts to lift and thrust the craft through the air. A link is provided below.

The 'laden weight' is the weight of a vehicle carrying some or a full payload.

Currently, the fastest helicopter in the US military is the CH-47F Chinook with a top speed of 196 mph (315 kp/h).

The development of the helicopter took place at many places simultaneously, and many helicopters flew before Paul E Williams was born.

African-American Paul E Williams was involved in the development of the "first useful helicopter" in particular the Lockheed Model 186 (XH-51). However this helicopter was not produced until 1962. He invented improvements to helicopter design, he didn't invent the helicopter.

See the related questions for links to his aircraft.

Leonardo Da Vinci invented the concept of flight which includes helicopters. He should be known as an inventor, not an artist. Art does nothing to help people! Life would be nowhere without his inventions.

Helicopters can be used in many different ways. Today, helicopters are used for transportation, for construction, for firefighting, search and rescue, and a variety of other jobs that require the special capabilities of the helicopter. Some police use them to monitor traffic, and catch speeders. They are used for emergency rescue such as grass fires. They are used for air ambulances when a patient needs to be rushed to a different hospital- because of their ability to take off and land vertically, and it doesn't need a runway. Military forces use helicopters to land men on the ground to fight. The military also transports food, missiles, needed medical equipment etc.. helicopters can also be used for recreation. Some people pay money to go up in a helicopter and fly over forests cities, and anything else that would look interesting from above.

Helicopters are also used for Aerial photography, Motion picture photography, Electronic news gathering, search and rescue, travelling, and touring or personal pleasures.

The type of fuel is specific to the type of engine, not the aircraft. Helicopters that have jet engines use jet fuel, and helicopters that have internal combustion engines use gasoline. However the General Electric T-58 had a device in the fuel control that allowed you to burn just about anything from avgas to jet fuel to kerosene.

I will assume by "sets" you mean "pairs". The truth is, some helicopters only have one set. Some have two. Put very simply, the more blades you have, the more lift you can generate, and so the more hauling capacity you have. Eg the Chinook has TWO rotors, each with four blades. It's used to lift some very heavy objects (humvees, many personnel etc). Whereas a small R22 only has two blades, since it's not designed to be a cargo lifter. The Main rotor is generally the one that is the most forward and creates most of the lift and general directional control (forward, back, left and right banks) Where as the tail rotor provides for a counter force to the torque created by the main rotor and also give you the ability to do what is called a balanced turn (means you won't feel like you're sliding through the air)

The first helicopter was made in 1909.

No African American invented the helicopter. The first practical helicopter was invented by Igor Sikorski, a Russian American.
