How the CH-47 Chinook Flies: Read Video Description, Too

A lot of people wonder how the twin-rotor Chinook gets its directional control without an anti-torque rotor...

Glenn Bloom, an actual Army CH-47 Pilot explains:

This video shows you the entire main rotor masts pivot according to pilot steering inputs. The agile Chinook also needs to be configured into ACH-47 gunships to clear landing zones for light infantry troop and light tank carrying CH-47s as was done in Vietnam with the Guns-A-Go-Go Chinooks with great success.

We must avoid being like the V-22 flying deathtrap which cannot even carry any light tanks and lacks adequate self-armament and escorts to do combat air assaults which has relegated them to doing just milk runs for supplies where the Iraqi rebels might not shoot at them to CON Congress and the American people that its multi-billion dollar waste is anything but gyrene and Bell Textron racketeering.

I do not understand a thing about this helicopter: when it goes forward or back, use cyclical or power of the rotors (collective)???????

[dynmicpara]

When you move the cyclic, both rotors pivot fore and aft or sideways and when you push the rudder pedals the rotors swivel in opposite directions to impart a pivot turn

awesome helicopter

Ah yes the

'eggbeater"

@sdrfgvrfgvsfravgdsvS when the pilot pulls up thrust (collective) all 4 servos extend causing all 6 blades to pitch. when he pushes forward on the stick, the front 2 retract and back 2 rise, causing a forward pitch attitude and revers for pulling back on the stick. when he inputs a right roll, the front right and back right servos retract while the opposites extend. I really hope this makes sense. hell im not a pilot, just a proud hooker Flight Engineer(crewmember)!!! GO BIG OR GO HOME!!!!!!!!!

The blades are counter-rotating, hence dampening torque. 67-18537, 1970.

Now i wanna see the controls for one of these. one landed at my school but i never go to go see it because of my damn teacher wanted to be an ass

Have you seen that clip with the Chook they set up to study Ground Resonance? It shook violently, the gears jumped, this causing the rotors to become unsyched, they of course clashed, and the rear turret peeled off. It was very sad to watch. But fascinating.

Yes mechanically fixed through drive shafting, but by definition they are synchronized. The drive shaft between the combining transmission and the forward transmission is referred to as the "Forward Synchronizing Drive Shafting". There are seven separate shafts that are connected by adapter and plate assemblies. The combining transmission is connected to the aft transmission with two shafts and the same principals apply. A disruption of any of this will cause the system to be "unsynchronized"

[atkinbuck]

Not synched, they are mechanically fixed through the drive shafting, and "phased" to ensure they cannot hit. Failure of lead/lag dampeners however would be bad to see. The funnny point is that the heads tilt on three points. The Longitudinal Control, the pivoting actuator, and the swiveling actuator. And the Pitch links are affixed to the rotating collar. This means somehow that 4 degrees of input transform into 3...

It's a pain in the ass to rig after a Phase also.

You forgot to mention something - that the rotors are synched to avoid them hitting against each other.

Great Video.
