Jet ranger turbine Start up instruments. How to start a Jet ranger Turbine engine

Booooooooooooooooooooooooooooo­oooooooooooooooooooooooooooooo­ooooooooooooooooooooo

Press the starter and at 15% N1 crack the throttle. Monitor the Temps and at 52% N1 release the starter button. Pretty simple start procedure. Temps can rise quickly so monitor and always be ready to shut the fuel off and crank to starter limits if hot start.

nice video, - thank you

[fishboard123]

Is the RPM gauge really that important? I mean do you have to always look at it?

[Chompchompyerded]

(cont'd) that bird was magical and made dreams come true! I flew him from the mid-70's to the late 80's, when the back-up pilot hit wires and rolled her up into a broken ball. I wept when I heard the news. He had been my child, my dreams, my four-four-two.

[Chompchompyerded]

Beethoven never penned music so sweet as the sounds of a Ranger turbine start-up!

This takes me waayyyy back to some wonderful times and a maroon and yellow bird tail named November-five-niner-four-four-­two. Not many women were flying back then, but (cont'd)

[Starbuckin]

I love the sound at startup when the gas ignites! awesome! I never get tired of it.

[Stefbenzer]

when do you relase the starter? when n1 reach about 50-60%?

[stealhty1]

im not sure about your turbine engine theorie,as far as i know the compresor & the turbine are linked by an shaft,however some turboprop engines have the gear planetary reduction box linked with another turbine turned by the gas stream of the last stage turbine

[tcalof]

The Rolls Royce 250 powering this Bell uses a spur adapter gearshaft connecting N1 (gas producer turbine or GP) and the compressor. It turns at 50,970 rpm. N2, the power producer turbine (PT), spins at 33,290 rpm , and uses another shaft to turn the gearbox. These shafts are inside one another. The PT drive is inside the GP drive in a tube called the pea shooter.

I can almost smell the fuel!

[Powershotknecht]

Super!

[bagpopuk]

If I was in the fortunate position of flying or even owning a Jet Ranger, I would never, ever grow tired of this procedure! Love the Start up!

[buzzburling]

The blades can turn at 14 percent N1 which is 14 percent speed of the first stage compressor. The air being blown across the turbine blades in the power section is enough to turn the blades. The compressor and turbine stages are only linked by the gas stream. If you turn theblades backwards you will hear the turbines turning but the compressor blades will not be moving. If you tuirn the compressor blades the turbines blades do not move. It needs a gas stream to turn the turbine

@buzzburling

test

[InflatablePlane]

WOAH!!! Look at that EGT jump during light off O____o.  Out of curiosity, during the spool up, does the rotor start to turn with the starter? Is the power transmission connected to a seperate turbine stage or is their some type of centrifugal clutch or fluid coupling in the gearbox?

[fatal9er]

yes...with this information I can finally commandeer that police jet ranger down at the airport! Thanks youtube!

[FelixThePony]

I still wonder why most of the JetRanger drivers keep pushing the start switch with fingers from their right hand while it feels so much more natural to use left hand thump... ;-)

[greg8698]

That's because the JetRanger flight manual says to use the index finger on the right hand when depressing the start switch.

[greg8698]

In addition, it is also because the left hand is being used to control the throttle on the collective.

[shapipple12]

because you gotta crack the throttle clock wise and its quite wierd doing that with a right hand

[megikon]

right hand on the starter,left hand on the throttle,when n1 reachs 15% crack throttle detent and light the fire

[greg8698]

Correct, you are!

[joboy666]

Some of us lucky folks get paid to do this every day. :)

[flymantobe]

great video...amazing sound...i could wake up to that sound every morning

[flymantobe]

great video...nothing beats the sound of a turbine starting up

[greg8698]

Yes there is. It's the sound of two turbine engines spooling up!!!!!

[audigod]

206 only has 1 turbine

[greg8698]

No shit, Sherlock! The only twin engine light utility helicopter in the 206 series is the 206-L4 Twin. However, the new 429 and the 430 have twin engines. If you had bothered to read the statement made, which I responded to, it was, "there is nothing like the sound of a turbine engine spooling up." To which I replied, "Yes there is. It is the sound of two turbine engines spooling up!!!!!"

[matthewsaddleworth]

makes three

[jamesonamac]

I just love the sound of a jet engine firing up.

[Elhombresombra]

That makes two of us... :)

[MetallicAddict15]

Me too; "The Grudge" (Tool song) starts with a turbine firing up; awesome way to start an album. =D

[Easyjet8810]

I remember from my Jetranger experience ride, what my instructor told me "you will keep your finger glued to the starter, if the temperature goes up too far, cut the fuel, but keep bloody cranking"

[greg8698]

Your memory is correct because if you don't keep cranking then you might end up with a "hot start." to which your next comment would be, "well there goes a cool $100-150K. Maybe I can blame it on, let's see who flew the aircraft before me?"

[desertswordsman]

I have time in piston helicopters but no turbine experience. When is one supposed to discontinue cranking?

[greg8698]

When your N1 gauge reaches 58% and the TOT is less than 150 degrees centigrade. The Rotor will start turning when N! hits about 15%. But you have to watch your TOT because the temperature will rise to about 580 degrees centigrade rapidly but will start to cool back down to 150 degrees. If for some reason you don't get a start, keep cranking until the TOT drops back down to 150 degrees Centigrade.. You don't want a hot start unless you've got $100,000 laying around.

[flingwing76]

greg, your numbers all come out of the POH somewhere but you have them all jumbled around where they dont make any sense. You might know what you are saying but it didn't come out right here.

[Easyjet8810]

Thats the point, you DO NOT, cos with a turbine, the thing gets extremely hot on starting, you need to keep the starter engaged as it will be the sole source of cooling air drawn through the engine, so if the temp goes high, close the fuel by all means, but KEEP CRANKING

[CivSi02]

Depends. Some turbine engine starters have whats called "holding relays" which engages the starter until a certain RPM value is met. Some you disengage manually

[jamestitan9]

nice starton jetranger are automatic starts they are a little less complicated than a longranger, nice vid

[buzzburling]

Actually prefer the long ranger start as you have more control of the temp. The Jet ranger can get very hot very quickly and has to be watched closely. The long ranger can be started quite cool and built up. Love em both but the Long ranger just edges it!

Thanks for the nice comment though! :-)

[HeliMedic80]

You are talking about the Bendix fuel control compared to Fadec ( I beleive)

I find the modulated start better than the "automatic" where you go straight to idle..

Gives me more control..

[geddon436]

that looks like quite a number of gauges to be looking at while flying

[buzzburling]

Hard at first but gets easier with practice!

[gezelle007]

isnt it all about keeping it level and straight?
