Tandem-rotor helicopters such as the CH-47 Chinook also use a counter-rotating arrangement. The efficiency of a contra-rotating propeller is somewhat offset by its mechanical complexity.

What’s the difference between a CH-46 and CH-47 helicopter?

They are run by different services- the CH-46 was operated by USN and USMC (before their retirement in 2015), while CH-47 is operated by the US Army and other foreign operators. Both the aircraft look similar as their genesis lies in the same program.

Is the Osprey faster than the Chinook?

Here the Osprey comes out on top again with a maximum speed of 275 knots (316 mph) compared to the Chinooks 170 knots (196 mph), so the Osprey could always get to the designated point quicker.

Can a Chinook helicopter auto rotate?

If you lose engine power and the gear boxes are intact the chinook can and does auto rotate in the same way as any other helicopter. If however you get a failure in the front or aft gearbox or a sync shaft failed then the rotors will hit each other and the aircraft will crash.

Why is the Chinook helicopter so fast?

Since it’s much longer than it is wide, the fuselage is relatively more efficient than more conventional helicopters with a less oblong fuselage. So with that much power and relatively lower drag, it is sure to be a fast mover.
