Helicopters
A helicopter is an aircraft which is propelled and lifted in the air by one or more large horizontal rotors. Focke-Wulf Fw 61 was the first operational helicopter manufactured by Focke-Achgelis in 1936.

What is a helicopter landing officer offshore?
The HLO is the person responsible for directing, loading, and unloading of personnel and equipment from helicopters on offshore platforms, ensuring all are secure prior to flight operations. It is usually done by a person that has another job Medic, or Crane operator as an example. The company decides who does the job. They also notify the pilot of sea state, weather that could interfere wit landing or take off.
What are some positive and negative aspects of the helicopter?
POSITIVE
- vertical take off (unlike aeroplanes)
- transportation easier and faster
- for emergencies (hospital and fire brigades)
- too noisy
Who created the first helicopter design?
Different answers can be given to this. Some Chinese people had created a basic design for a flying machine that used bamboo and were just used as toys in the 4th century. It is said that Leonardo Da Vinci had a design for a helicopter. He lived in the 15th and 16th centuries. Since then, many other scientists and inventors have come up with designs getting closer to what we would think of as the modern helicopter. It was only in the early 20th century that these machines were actually begun to be built and flown.
What companies make airplanes?
Boeing, Lockheed Martin, Bombarider, Airbus, Cessna, Mooney, Bell, Sikorsky

Navy seal simuaate helicopter crash in training?
Yes, most naval personnel, including Marines go through a training course known as the dunker. This course simulates a helicopter crashing in the ocean and teaches you how to safely prepare for the crash and egress the helicopter after it has crashed.
Q: Why is a helicopter called a "Chopper"? A: I think the names comes from the sound of the blades make: whop-whop or chop-chop. FYI, the helicopters that have the loud popping of the blades are usually a 2-blade of the Bell Helicopter design. The multi-blade helicopters do not have a sound as distinctive as the Bell helicopters. The sound comes from the blade striking the vortex generated by the blade ahead of it.

How many people fit in a helicopter?
There are many different helicopters, the biggest can carry over 100 passengers. Most commercial helicopters seat about 16-20 passengers
Were helicopters used in second world war?
The Germans:
The Focke-Achgelis FA 330 Bachstelze (English: Wagtail) was a type of rotary-wing kite, known as a gyroglider or rotor kite. They were towed behind German U-boats during World War II to allow a lookout to see farther.
Because of their low profile in the water, the submarines could not see more than a few miles over the ocean. To solve this, the German admiralty considered a number of different options, including a folding seaplane (Arado Ar 231). In the end, they chose the FA 330, a simple, single-seater autogyro kite with a three-bladed rotor.
The FA 330 could be deployed to the deck of the submarine by two people and was tethered to the U-boat via a 150 m (500 ft) cable. The airflow on the rotors as the boat motored along on the surface would spin them up. The kite would then be deployed behind the U-boat with its observer/pilot aboard, raising him approximately 120 m above the surface where he could see much farther; 25 nautical miles (46 km) compared to the 5 nautical miles (9 km) visible from the conning tower of the U-boat. If the U-boat captain was forced to abandon them on the surface, the tether was released and the FA 330 descended slowly to the surface.
When not in use, the FA 330 was stowed in two watertight compartments aft of the conning tower. Recovering, dismantling, and stowing the FA 330 took approximately 20 minutes and was a difficult operation.
On the Allied side:
The YR-4B was full-scale wind tunnel-tested at Langley Army Airforce Base in Hampton, VA in 1943--JC Lovell, father of astronaut Lovell, was a member of the NACA team that undertook this testing. They called themselves the 'Society of Rotor Wretches'--I have the group ID badge created by this team bearing J. Lovell's name upon it, and HIS copy of Notes on Helicopter Design Theory, by Alexander Nikolsky and translated from the Russian original, and bears on the inside cover both JC Lovels signature and then current address in Hampton, VA
On 22-23 April 1944, U.S. Army Lieutenant Carter Harman of the 1st Air Commando Group conducted the first combat rescue by helicopter using a YR-4 in the China-Burma-India theater. Despite the high altitude, humidity, and capacity for only a single passenger, Harman rescued a downed liaison aircraft pilot and his three British soldier passengers; two at a time.[4] On 22-23 January 1945, another rescue by the R-4 involved several legs for refueling and navigating through passes between mountains nearly 10,000 feet (3,000 m) tall, to reach a weather station located at an elevation of 4,700 feet (1,400 m). The higher than normal altitude required a downhill run of 20 ft (6.1 m) to get airborne.
Will similar investigations or expirements always have the same results?
no because they could do in different environment and could change.
How many helicopters did Nicholas Cage jump over at the football stadium in ghost rider?
seis helicoptoros
Why is helicopter better then planes?
With the exception of certain jump jets, helicopters can land easier than planes and better maneuverability. Planes are much faster and can carry stronger air to air weapons or bombs, but helicopters have better air to ground precision weapons.
Helicopters are better for ground force support.
helicopter requires less space instead of planes.
Why do helicopters always have a set of two blades?
Helicopters have 2 sets of blades to keep the helicopter balanced. This is due to the unique shape of the helicopter.
Who was the inventor of the helicopter in 1936?
Igor Sikorsky and Paul Cornu invented the helicopter in 1907. It was the first operating helicopter to actually take flight.
What is the fastest us army helicopter?
CH-47 Chinook.
ANS 2 The AH-64 Apache is much faster than a Chinook.
