Gas turbine, Rolls Royce Spey 101 jet engine

[EasternMerchant]

I need this for my scooter!

[antigen4]

bet that puppy could go pretty fast if you take the blocks off the damn wheels...!!

[theONLYsebo]

wow where did you get it?

[Deadshot001]

i want 1

[AccessAir]

Would have loved to hear it at full throttle....

How much different is that motor from the RR Spey 511's that hang off the side of my G-III?

[terrafirmajets]

HI there,

Architecturally the Spey 101 (RB 168-1 and your Spey 511 are identical with a few alterations to engine mountings and acessories driven from the High and low speed boxes.

[terrafirmajets]

Both engines feature the same compressor, bothe hp and lp and turbine rotors, the bypass ratio of each is identical at 0.7-1.

The Spey 101 here has a greater permissable maximum rotational speed than the 511 both at max cont and T/O. Due to this addition of an additional 150 rpm to the max n1 limit the mass flow of the 101 increases to 123lbs/sec as opposed to the 51 with a mass flow of 121lbs, sec. This increases the thrust of the 101 max @ T/O to 600lbs more than the 511 engine.

nice video!

what's the model of plane, of this turbine?

tks

[terrafirmajets]

This particular engine was installed in the Buccaneer S2, however many similar varients were produced for different applications including a license built version by the american with a zero stage for the corsair/crusader and a reheated unit (202) for the Phantom along with several exclusively civil varients.

I wonder how fast it would go if you cut the anchors..

[davidleyman]

Of course, you are perfectly correct. I was a (Nimrod) Spey specialist but that was 20 years ago. Amazing how many details you forget. My bum is sore through kicking myself! I am taking the CASC to bits at the moment and needing a photo of the geometric linkage for my book (Google?). Ideas, please?

[davidleyman]

Sweet. I don't see movement in the VIGV's - is the ACRA functioning?

Hi David,

The only VIGVs on the spey are on the inlet to the HP compressor which of course you are unable to see. The inlet guide vanes that you can see on the front brg housing are fixed. The VIGVs on the hp spool only begin to move at around 80% anyway which I was nowhere near on these runs.

Glad you like the video, it was fun to do

@terrafirmajets

Oh, thanks for the info. I thought the Spey does not has VIGV. Are all Spey engines have VIGV? I did not aware there is any actuation mechanism on those Speys for HS121 Trident. But it might be because I did not pay enough attention to those engines when I was in college. BTW, you are pretty brave, I will not have the gut to run an IC engine like that, let along jet engine. XD

[terrafirmajets]

That "N1" you refer to is the inlet guide vane pack which is static and part of the LP front brg housing. If that rotated I would be in the poo a great deal! The Lp fan can be seen behind the IGVs. If the LP had been frozen I would had been unable to perform a succesful start. Thank you for your comment chap...

jets are brilliant! they gimme goose bumps

Hello Paul,

Great video, It's got to be loud and very scary where your standing at in the video. Going to run mine tomorrow, i will send you a copy of the video.

That's a really big fokker.

Hi there,

It is similar. The fokker used the Spey mkk555 civil engine. This however is a military mk 101.

[OneExoticBoy]

is this the same engine used on the Fokker F.28?

[leokimvideo]

Thats a all mighty backyard jet, and how personal you are with it..lovely..

Just wonering what is your wallpaper, it looks interesting..

[terrafirmajets]

I did have the shakes for a bit afterward. God it was fun though!!! I don't get to do the bigger engines as much as i would like as it take so much planning (and cash)to get them and the equipment required to somewhere that you can chain them down (In case the throttle lever falls off halfway through and you need to pull the pipe out of the fuel drum or find your mole grips and shut the throttle again hehehehe!)

[terrafirmajets]

The wall paper is a Turbomeca Palas engine of 350lbs thrust and 159lbs. One of their first succesful turbojets, a bit lumpy but nice though. I have been after a good one for years. They come up from time to time but they are either over priced or wreckers

[hulmeely]

testing..

[proprietary1]

wow!!! thats alot of power!!

[Kpeters]

Nice video thank you!

[dms654]

Great video, thank you.
