Title: Intermeshing Helicopter Design
Post by: Bilal on May 18, 2012, 09:42:10 AM
Hii,
can anyone tell me anything about Intermeshing Rotor Disc Helicopters? How they work, how the flight controll is achieved and most important, why the rotor discs never clash?

Thankyou

Bilal your answers are here

http://en.wikipedia.org/wiki/Tandem_rotors

The two rotors are linked by a transmission that ensures the rotors are synchronized and do not hit each other, even during an engine failure.[2]   read this line.

Swizera Sir,
I didn't ask about Tandem Rotor helicopters......instead what i wanted to know is reffered to as 'Synchrocopter'....google it and you'll know what i was referring to.

Commertial examples of this technology include Karman K-225 built by american company Karmen Aircrafts during WWII.....and is widely used today as 'sky crane' due to its huge weight lifting capacity,

neways, thanx for replying:)

Bilal, the peculiarity, of this mechanism, spells itself, in its name.. its a compound gear box arrangement, to avoid any accidents with blade arrangements.. i am holding a small cutaway, of this mechanism, lying somewhere here at home.. will explain with it ..  :thumbsup:
