Coaxial. Coaxial rotors are two main rotors mounted on one mast, sharing the same axis of rotation but turning in opposite directions, one on top of the other. The control along the vertical axis is produced as a result of different lifts, thus differential torque, of the two rotor discs.
Q. How does a single rotor helicopter work?
In single rotor helicopters, the antitorque rotor or tail rotor counteracts the main rotor torque and controls the fuselage rotation. Coaxial rotors solve the problem of main rotor torque by turning each set of rotors in opposite directions. The opposite torques from the rotors cancel each other out.

Q. Can helicopters fly without rotor?
One significant advancement in the last decade has been the no-tail rotor, or NOTAR, helicopter. As you now know, vertical-lift flight is impossible without a tail rotor to counteract the torque produced by the main rotor.
Q. How does a helicopter fly forward?
The rotor blades are pitched lower in the front of the rotor assembly than behind it. This increases the angle of attack — and creates lift — at the back of the helicopter. The unbalanced lift causes the helicopter to tip forward and move in that direction.
Q. Can a helicopter fly in a tunnel?
Helicopters can (and have) flown into and through wide buildings like hangars and abandoned factories. Helicopters almost certainly cannot fly for any length of time in narrow passages like tunnels.
Q. How much do helicopters cost?
The average price of a helicopter is $1,794,793. However, the least expensive pre-owned helicopters may cost as little as $100,000. The most expensive helicopters on the market cost up to $27,000,000. The average asking price for a pre-owned Bell 407 helicopter is $1,907,000.
Q. Is it cheaper to fly a plane or helicopter?
Well, the answer is pretty simple: it’s more expensive to learn to fly helicopters because of the cost of helicopter rental and flight instructor fees. Rental rates on a plane are significantly less than rates on a helicopter and, given the lower supply of helicopter instructors, their teaching fees are also higher.
Q. Do you need a degree to be a helicopter pilot?
Most helicopter pilot employers require an associate or bachelor’s degree in math, physics or aeronautical engineering. Some universities that offer aviation programs also provide the process to obtain licenses.
Q. Is being a helicopter pilot stressful?
Mind you this is mentally exhausting. Flying helicopters isn’t like flying airplanes, where you can enjoy the ride more. Flying a helicopter is work, and lots of it. If you spend at least two hours flying around, you’re going to be tired.
