Bell Helicopters Stabilizer Bar Operation

Bell Helicopters stabilizer bar used on some of Bells two bladed models. The bar wants to stay in one plane and is used in conjunction with the cyclic control changes making the helicopter more stable.

Thank you! I've been online for a week trying to figure out what that thing did.

Some variants of the US Marines UH-1N’s or 212’s with effectively the same rotor as this 205 do not have stabilizer bars. The bar, mixing lever and dampers are removed and replaced with a stand alone mixing lever. I believe like a 214B at minimum the SCAS has to function.

Very educative.. appreciated 🙏🚁🚁🙏

Thank you a lot

Well done video. I remember that school! I do think we could lock the stab bar at neutral and no adverse affects would happen! Only one way to find out.

Very good

[@ujungkulonpost]

So good

Thank you for this video, why there is no stabilizer bar in rotor with 3 blades,, for exp ..schweizer

Lockheed developed a gyro stabilized rotor in the late 1950s/early 1960s that could be used on a rotor with any number of blades. Sample patent: patents.google.com/patent/US3135335

Because they are fully articulated type Rotor

Haa. This complex moves explained in seconds ??? Is how they learn in flight school ?? Theoretically…. In reality it takes along time to realize what’s happening the roll of every moving part. And why !!! But he sounds very convincing..

I understood what he was saying for the most part. The stabalizer bar can micro adjust rotor blades if the copter is blown sideways, due to the stablizer bar experience gyroscopic forces and will not break plane as easy, so it will input corrections back into the rotors... not super complicacted. well maybe for you.
