[HumblePilot]

Does anybody know which helicopter types have been provided with lateral main rotor mast tilt (figure 9-5)?

 

Please mention

• helicoter type
  
• magnitude (degrees)

Enstrom 280, 28

 

I believe it is about 3 degrees.

All the Bell products have something comparable, I believe.

Thanks folks

 

This feature is not very well documentated. I checked out several manual and couldn't find anything.

If anybody has more information ... everything is welcome

I'm very familiar with the 206 and the 407, but what is the 406?

[HumblePilot]

check the following site

 

Bell 406 and Co

 

... but I guess Linc is one to ask.

Why would they call and OH58D a 406? That's a civilian designation, and the OH58D has never been issued a civilian type certificate, AFAIK. That site also omits several civilian 206 variants, and seems in general, at a quick glance, to be a less than authoritative source.

Hey Link ... That one I think is definitely for you....

But I would be glad if we could stick to original subject (lateral mast tilt).

[Linc]

406 is the design designation. Bell sold a number of 406 Combat Scouts to Saudi Arabia. They had different mission avionics and sight (HeliTOW, not the MMS) and they were armed long before the OH-58D was. Sometimes you hear the 406CS referred to as the MH-58D, even though they aren't really 58Ds.

 

P.S. The 407 body design is based on a 206L body but widened by about eight inches. The 406 is simply the 206 body with the unique-designed dynamic components that eventually were adapted to the 407.

The Kaman SH-2F/G has a forward and left cant which allows it to hover in a level attitude - "wings level"

TH-67 (206B, I think?) has 1.25 deg to the left.

The R-22. Somewhere in the 1 1/2 degrees range if I remember correctly.
