Boeing Vertol CH-46 Engine Start 

So true. I’ll never forget that sound

My dad served in HMM-164, semper fi!

I feel the same about the CH-47

fist time us ka mil kaya nahin dekha sabb log malum nahin sakda ꯃꯦ.ꯅ.ꯏ.. ꯃꯩꯇꯩ

I remember the 46 having a better crash record then the 53. Semper Fi

Why up? Look down at the ramp so your ass doesn’t slip.

It's when it stops leaking that's the time to worry

true

Yep it does look like a smiling frog too lol

@@IndigenousAmericanTrucker The startup is quick as well

It's a sea knight

yeah

@@frost7724 It'd the Rotor Breaks

Rotor breaks I believe

They must have been testing after phase or some repairs. The EAPS is being run , (Engine Air Particle Separator) before startup. And the fire bottle is on tap.

I was a gunner in HMM-165 in Vietnam - White Knights!

Semper Fi bro.

i’ve seen one before also but not a marine corps one, it was a columbia helicopters one

That's the rotor clutch/brake system. It keeps the blades from hitting the pitching deck when spinning up and down.

Linwizz oh ok, so how come the sea knight doesn’t make the same sound as the ch-47 chinook when the sea knight is also a tandem rotor? the ch-47 blades make a thumping sound

SuperSmashBros.mp4 the -53’s rotors sit higher off the ground. As for the thumping, it’s because each set of rotors only have 3 blades, so in helicopters the less blades you have, the more you hear thumping (think Original Uh-1 and Bell 206 vs UH-1Y Venom and Bell 407).

@@frost7724 The Sea Knight and Chinook are two different helicopters . The Chinook is larger and more powerful with larger rotor blades which is why it sounds different. Also, there’s no clutch for disconnecting the rotors during startup and shut down. Free-turbine turboshaft engines can be started with the rotor brake on. The reason the rotor spins up so fast is that both engines are already at idle when the rotor brake is released. Usually the rotors are slower to speed up if they are free to turn as the engines are started one at a time.

Fire watch

UraniummasterX76 L i like how the blades start moving pretty quickly

@@frost7724Theres Rotor breaks

Pakistan Maybe

DAMN STRAIGHT IT WAS!!!!!!!!!!

That’s why it’s being retired and the chinooks are anticipated for another 25 years of service?

@@Justslothin Boeing quit building the CH-46 in 1971. They were finally retired because the ones that were still flying had 'tired' airframes and new parts were no longer being produced. I was USMC Infantry and the 46 was my favorite, and not just cuz it beat the hell out of walking 😉.

There was an old saying: When you board a 46, look up. If you see a hydraulic leak, that's a good sign. It means the helicopter still has some.
