Helicopters

Most helicopters fly at about 170 knots, but some are faster.

232mph

The CH-47 Chinook has a maximum airspeed of 170 knots, and cruises at 130 knots. The AH-64 Apache has a maximum airspeed of 158 knots, and cruises at 143 knots. The Chinook has a slower cruise speed, but can outrun the Apache due to its higher maximum airspeed.

Chopper.

Air platforms. Ability to hover. Think about it.

Petrol is a Fossil fuel. It gives out enormous amounts of Carbon-dioxide on combustion. All vehicles use petrol. So it causes environmental pollution.

Vertical Envelopment, or the use of helicopters in combat, was first introduced in the Korean war.

Da Vinci had an idea for one, but it was only on paper. The first flown one was in Spain on Jan., 17, 1923 and was called a gyroplane. The man who flew it was named Sr. Juan de la Cierva.

184 mph

we use chinooks, blackhawks, tigers and kiowas.

I believe the person is asking how many, as in the number, of helicopters are in the army.

From Boeing, off the shelf about $12m.

You will however need to demonstrate that you are a government, friendly to the USA before the sale will be approved.

It depends on the plane. If it's a small one like a two or four seat cessna, 150 gallons is pretty average. Jumbo jets might carry about 48,000-60,000 gallons

Indeffinently within fuel limitations, or system temperatures.

The UH-1 Huey (built by Bell Helicopter), officially called the UH-1 Iroquois helicopter. With the exception of the AH-1 Cobra; US Army choppers are named after US Indian Tribes. Over 5,000 UH-1 (Utility Helicopters) were used in Vietnam, nearly 12,000 helicopters total combining other types. Of those 5,000 Hueys (a slang term derived from the letters U-H), about 3,000 were destroyed in Vietnam. However, about 8,000 Hueys were manufactured. The Huey performed more types of combat than any other bird...medivac, gunship, troop insertions, re-supply ships, SAR-Search and Rescue...to name a few. Other birds used in Vietnam, but not so famous: 1. Kiowa (civilian version is the jet ranger) 2. Cayuse (flown in TV series PI Magnum, starring Tom Selleck, in the 1980's) 3. CH-47 Chinook (twin rotors on top, ramp in the rear for cargo) 4. AH-1 Cobra (US's First factory designed/built attack helicopter) 5. CH-53 Sea Stallions 6. HH53 Jolly Green Giants

His words caused her abase. Abase means to belittle or degrade someone else with the way you are behaving towards that person.

the blade is called rotor blades
The rotor blades on top are called Main Rotor Blades, because they are the main source of lift for the helicopter. The smaller rotor blades on the tail are called Tail Rotor Blades.

Landing struts, and the 'runners' are known as skids.

They don't need an airstrip. They can take off and land anywhere (weather and ground fire permitting).

Most helicopters out there do not have pressurized cabins so the general service ceiling for helicopters today is 10,000 ft. So to answer your question anywhere from 0-10,000 ft. depending on airspace regulations.

It depends on model.

it is the small rotating "fan" in the back

Jets are much faster .
