They have a rotor clutch and break system, because spinning up and stopping the rotor on a moving ship is dangerous. So they get it turning and stopped quickly.
@@linwizz2126 It's not a clutch system. The power turbine is not mechanically connected to the engine shaft which means that the engine will still run even if the rotors are stopped. It is the rotor brake that stops and holds the rotors during shut down and startup. In this video, the pilots started the left engine with the rotor brake set, and then once that engine was running at idle released the rotor brake to allow the rotors to spin up. They then started the right engine.
Too bad that jet interfered with the audio. Takes me back...... NavAir, 77-81, stationed with HC-11 on NASNI, I think I still remember how to work on multiple systems on this bird.

That rotorblade Startup is quick

@@nocalsteve so the brake slipped because that can cause blade droop and impact
@@linwizz2126Its called a rotor brake
I see these flying by every now and then
Miss Those Frogs
Flew off the USS Kitty Hawk in one of these back in the 80s.
Niiiice

Was a crewchief on a D model 72-74. Lot of memories.
Love the witch tits!

I remember them from my tour of duty at Futenma MCAS during the late 80s. Avionics Technician.
Wow
I was flight deck LSE on my second ship. The only from NM. My frogs where all mine.
ผมเห็น เครื่อง บินแล้วสบายใจครับ
My favorite noise
Which airport was this taken from?
Which aircraft is making that sound at 1:22 to 1:34? (not talking about the Sea Knight helicopter)
Could be almost any small jet plane since the video is from a civilian airport.
Sounded like a Boeing 737
Phrog
I never see these types of helicopters any more. Were they retired or something?
Casimus Prime yes they are retired
Obsolete device but wasn't it great while it lasted?
Replaced by the Ospreys
Still alive and kicking in the State Department though
Columbia helicopters uses them. Kawasaki still builds them.
จะให้ทหารลงบัตรที่ตั้งเหมือนเลขผู้แทนราษฎรเขาคงเลือกเครื่องรุ่นเก่ามากกว่า
Como se llaman las 2 antenas que tiene en la cabina?
Chinook makes the same sounds on APU.
go to 1m20sec to skip the nothing
Yuma?
They fly over my house and shake the whole house
Fire Bottle???
Boeing Body Bags
