Helicopters

Yes. I've seen a video of a CH-53 performing a loop. I think an AH-64 has performed a Loop, also. Another maneuver that helicopters have accomplished are Split-S and Immelmann and a Barrel Roll. The newer helicopters designed with composite blades and in particular, composite structrure that provides support and control to the blades are more capbable of these aerodynamic maneuvers. The first helicopter loop ever recorded was in 1949 in a Sikorsky S-52. Harold E. "Tommy" Thompson was a test pilot for Sikorsky after WW2. He performed the loops at Bridgeport Connecticut. The S-52 had a 245 HP Franklin engine from a Tucker automobile. It also had the first all-aluminum blades from Sikorsky. That combination allowed the S-52 to set world speed records (129.6 mph), altitude records, and the performance of the first loops ever recorded. Here is the link to movies and stills of the S-52 looping: http://www.youtube.com/watch?v=xhRUGKa_ImY And here is proof...

Most fly between 30,000 and 50,000 feet.

A helicopter is an aircraft that uses rotors rather than traditional wings. The rotors act as airfoils and lift the vehicle, allowing it to hover or manueuver in any direction. Some helicopters are powered by gasoline engines and some by jet turbines. They are employed for a variety of operations including transportation, rescue, medical evacuation, and military operations.

Well, they don't always.

The advantage of the design of the helicopter is that it CAN take-off and land vertically and does not require a long runway. That allows it to delivery injured patients directly to the roof of a hospital.

Many helicopter are equipped with small wheels that allow it to taxi. This also allows them to take-off and land with some roll. When a helicopter is heavily loaded, it usually takes off by at an angle and not vertically. This also allows the pilot to watch for other traffic.

VTOL or Vertical Take Of and Landing was developed to provide access to any remote or space limited landing zone.

A helicopter is a flying vehicle that uses rotors on the top of it. It is able to fly by simply taking off vertically, instead of having to traffic through a runway, like an airplane.

you have to complete a mission that leads you to a helicoptor. the mission is called "False Idols." (staunton island)

Well, we go back to about 400BC for a Chinese toy made of bamboo that demonstrated the principle.
Forward a few centuries to 1870 and Alphonse Penaud developed such a single-axis toy powered by a rubber band. It seems that one of these toys given to two brothers Wright propelled them to an interest in flight.

But it is not until the 1930s that Focke-wulfe FW 61 was demonstrated.

But Igor Sikorsky in 1942 produced over 100 of what would be recognized today as a standard helicopter, with importantly, a tail rotor to counteract the torque applied to the body by the main blades.

But to fill out the picture, the autogyro a.k.a. gyrocopter enters the scene about 1923, with successful flights.

It must be noted that the most recent announcements re helicopters (October 2010) and their improvements in speed, once again hail somewhat to the gyrocopter! They have stubby wings and a main forward thrust prop, with a separate set of blades for lift.

According to the FAI, the distance record for a rotorcraft without landing is 3,561.55 km Date of flight: 06/04/1966 Pilot: Robert G. FERRY (USA) Course/place: Culver City, CA - Ormond Beach, FL (USA) Rotorcraft: MDD-Hughes YOH-6A (1 Allison T63-A5A, 317 shp)

Military helicopters can refuel in mid-air so they potentially can fly indefinately. Of course, the crew probably can't take that much pounding.

Answer Nothing more than any other type of airplane or car. Most helicopters are powered by jet engines that use a gearbox to power the rotor blades. The turbine jet engines are relatively evironmentally friendly compared to other internal combustion engines.

Safety Orange. The name 'black box' is a misnomer.

1912 was when the first helicopter flown

It is about 100,000 to 500,000 thousand dollars. And it depends were u by it.

The first Helicopter was made by Igor Sikorsky, in 1939.

Sir Edmund pierce Jacquier first invented the single rotor helicopter in the year 1989.

1957 by Boelkow called the Bo-102. It had a single bladed main rotor and a single bladed tail rotor.

In Germany, inside a warehouse, with Hanna Reitsch at the controls. About 1933.

There is a part on a helicopter that is called a swashplate, it converts non rotating controls into rotational movements via an inner ring riding on a bearing attached to an outer ring that is able to pivot on the shaft. On a tandem helicopter it uses both of them in unison most of the time. A helicopter maneuvers by adjusting the pitch of the blades to be more biased to one side, basically pushing air at an angle, causing it to go the opposing direction. So when a tandem rotor helicopter wants to fly forward it pitches both (or even one depending on what you want to do with it exactly) to fly forward. This all applies to the cyclic (steering). For yaw (turning) they either tilt the back only (to pivot around the front rotors), the front only (to pivot around the front rotors) or both (to pivot around the center). with the joy stick!!!!!!!!

A helicopter with twin main rotors steers by flying the rotors just as a single rotor helicopter would do to make a turn. A single rotor helo uses the main rotor to tilt and bank. For a twin rotor helo, the two rotors do the same but can pivot the helo about its axis. The controls are a bit more complex than for a single rotor.

Helicopters fly somewhat close to the ground. They fly near the troposphere. They fly at a lower altitude than planes.
