its been awhile but, roll the eng up to 1600, then turn hydraulic pump on, then increase throttle to engage rotor and engine. Split the needles to engage the mechanical connection, then run it up to operating RPM. I'm flying the S64 and the S61 now. I would like the opportunity to fly the S58 again.
VMC Aviation, My dad used to own a couple of Sikorsky S-58 helicopters years ago and I remember that sound. I've been in them and around them. It beings back memories.
@@VMCAviationVideos Helicopter logging down in the swamps, he was the owner of a logging company from 1976 to 1994. He had a paid crew working tht log landing and in tht swampy areas. The name of company was Helicopter Lumberjacks. It was a white S-58 piston powered helicopter with one this red and one thin red line around tht helicopter with tht company title and the logo on both sides of the tail boom. N8503J was the number. But he didn't own them both at one time, he would use the insurance coverage to make another purchase, his were Navy surplus, then he used tht insurance coverage to purchase the H-19, he had about four of them but not all at one time.
I swear this helo use to be an aerial lift out of Winder, GA. I watched him fly A/C units on and off a shopping center one time. The S-58 remains one of the most desired helicopters for aerial lift. Some have been converted from radial to turbine.
So, at 5:05 in the video the tail wheel seems to be bouncing, thats not normal. I flew the S58 round motor for 1500 hours in the late 80's early 90's doing construction work, mostly air handling equipment and steel work.
I flew on Wessex helicopters which was developed from the S-58, it was normal to stand up and talk to the pilot when required. My biggest concern is for anyone who wanders down the back where the tail rotor will take off your head!
Agreed. That must be why the banding was painted at different points on each of the tail rotor blades. The irregular pattern draws attention to itself while turning .
Big balls on the guy, but I have to wonder what their plan was if the aircraft went into ground resonance. When prepping for a ground run, we always assumed the aircraft might have to lift; we'd never have started the rotors with a steering arm attached!
Cars need multi speed gearbox primarily for a wide speed range. In a helicopter the rotors run at the same speed all the time it is operating so a gearbox is not needed to give a range of speeds. The clutch is engaged on the ground when the load on the rotors is lowest and never disengaged unless the engine fails. There is enough engine power at the point of clutch engagement to achieve this without stalling the engine.
There's a fluid coupling or torque converter between the engine and transmission that allows for engine startup and bringing rotors up to speed, once rotors are turning then the engine is idled down to allow the one way clutch to engage and then it is positive direct drive for flight.
Thanks for the highlight and nice ❤️!

current river so is it just the blades out of balance? Or can bent drive shaft do that? I don’t suppose it would last too long if the tail rotor driveshaft was bent.
@@56WagonWheel I've seen a tail rotor out of balance do that, but bounce is usually quicker. I really doubt bent shaft, it definitely wouldn't last long. It could also be a mount bearing for the driveshaft. If i was really looking i would concentrate on tail fold and airframe integrity, if everything else checked. We had a CH53D that bounced so bad, nobody would fly it, and we spent close to a year trying to find problem. Sometimes it's just them Gremlins!!

Clutch is provided mainly to allow the engine to be disconnected in case of failure, which allows the rotors to keep spinning as they autorotate to a landing.
I worked on these, what do you mean by 2 speed gearbox? never heard of it. There is a simple clutch connecting engine and main gearbox. Looks just like a torque converter on a car. Defin
@@currentriver4951 every single video i have seen of these they have radial engine with 2 speed trans. you'll hear them start up, run 1st speed up, drop clutch, go to 2nd, then run 2nd speed up to operating rpm. for instance in this video from 2:23 to 2:53 it runs up, rpms drop, then another gear is selected, and rpms start climbing down low again and another run up of a gear. i will accept the fact that maybe it is a torque converter... but damn if that is true, it sounds sloppy as shit as how long it takes to switch between gears and the drop in RPM
@@ilovegoatsecks I definitely hear what you are saying, but ive also been in them during quick starts, and its just start and run up. Ill ask around to some of the old timers i worked with.

Is there a rotor brake in that old bird?
Good question
A main blade tracking session wouldn’t go amiss …
Are they supposed to hop like that ?
I wonder how it engages the rotors without stalling - presumably it has to change gear a few times before takeoff rotation speed...
I don't have the answer to that
Cars need multi speed gearbox primarily for a wide speed range. In a helicopter the rotors run at the same speed all the time it is operating so a gearbox is not needed to give a range of speeds.
