Turbofan Engine for L39 Albatross test run

Published on Aug 26, 2016
After a few delays in the process, we get to run a small turbofan engine, and find that it is performing very well.
We also learn that what we thought was a fuel system vent was a recirculation valve on the fuel cooled oil cooler.
We pumped jet fuel all over the floor, and the engine ran perfectly.

RR Marine Spey turbine engine test run

Published on Apr 30, 2016
First test run of a Rolls Royce Marine Spey gas turbine engine.
The oil consumption and vibration levels were both under the required parameters, and after some adjustments,
this engine met the specified power output for its application, which is powering a medium sized ship to healthy speeds.
The smoke seen at high power running is coming from an air-oil separator tank situated on the floor
to the right rear of the engine. All normal, everything went well.

Throttle Response : J79 Turbojet

Published on Oct 11, 2014
We did three runs over two days of this afterburning turbojet. We were trying to isolate and correct a transitory variation in thrust at high cruise.
We varied the power from about 60% to medium afterburner in order to fully bracket the suspected transitory range.
This is an aircraft engine, and we are testing is because that is what we do. S&S Turbines is a company that services industrial and exeprimental aviation gas turbine engines.

Sabre Jet Engine: first start

Published on Aug 29, 2013
The first start and initial test run of the Orenda type 14 turbojet that we have been working on for almost a year now... you and me!
It's been a lot of work, and now it's all on the line as we crank this baby up, hit the sparks and spray those combustors with Jet A.
It was an exciting and exhausting day...
A special note: this is not a hot start, but fairly typical of the older generations of turbojets to have flames shoot out the tailpipe on startup.
The video response is from Burning Man participant Kunal Dovedy, and the engine section he used is the exact one featured in my video "dropped into a turbine engine".

Fighter Jet Engine Afterburner Test

Uploaded on Oct 6, 2007
J79 with afterburner at the S&S Turbines open-air test cell in Ft. St. John B.C.
Taken from a Kfir fighter, after it had suffered damage.
The compressor rotor was destroyed by FOD (foreign object debris) ingestion, and was completely replaced.
This is the same engine as that in the F-104, F-4, B-58, and some early F-16s.
The "smoke" you see coming from the engine at full power/afterburner is not smoke, but unburnt fuel. The afterburner in these shots is spraying fuel into the jetpipe, but the igniter in not functioning. What you see is 50 gallons per minute of jet fuel being blown out the nozzle.
Later shots show the afterburner functioning.
Comments are welcome, and questions will be answered

Air Dyno Update 1

Published on Jan 18, 2014
The first couple of runs in the development process of the Maddex Turbines air-brake dynamometer, with which we will test the Allison / RR 501 industrial series of turboshaft engines. They are a very slightly modified T-56 turboprop, and produce between 3,000 and 5,000 Hp.
I am not working on this project, but I was able to nab some footage, and hack together this update for you.
The "smoke" you see during the first run is actually oil mist coming from the lube oil reservoir vent on the totally independent system of the load compressor; the one in front of the running engine.
Notice there is no mist coming off the running engine in the second run...

Orenda test at S&S turbines : VERY LOUD

Orenda turbojet test at S&S Turbines : LOUD

Uploaded on Sep 24, 2007
Orenda turbojet, predecessor to the Iroquois, built to power the Avro Arrow.
The Orenda was designed and built in Canada to power the Avro CF-100 "Canuck", an RCAF interceptor in the late 40's. Some of these engines were also used to power the Canadian built CF-86 Sabre, under license from North American Aviation.
The unit you see here was assembled from the best parts of three separate engines; two industrial and one from an aircraft.
The work was performed by Maddex Turbines in Ft. St. John, BC during July and August of 2007.
Maddex, originated by Brian Maddigan, has built, repaired, or overhauled several Orendas, as well as these Rolls-Royce Jets:
The Avon, which powered the Lightning interceptor, the Canberra bomber, and the Comet Airliner.
The Olympus, which powered the Vulcan bomber and the Concorde airliner.
The Spey, which powered the A7 Corsair, and was the engine used by the world record holding land speed car Thrust SSC (two Speys).
Also the Allison 501, which is the industrial T-56, the engine from the C-130 Hercules transport, as well as the AC-130 Spectre Gunship.
The unit in this video is used to generate electricity, and you see it here making about 10,000 Hp in the S&S Turbines test cell, also in Ft. St. John.
That's Brian and Moto-Steve checking the engine at idle, and Robin Sipe, of S&S Turbines at the end, indicating that this historically significant engine has passed the test, and is ready for operation.
Sorry for any busted speakers, but this is a real jet engine. As you can hear, we almost killed the camera's mic.
In the second pan scene, which is also the loudest, the engine is at full power. It's running on propane, which is being fed thought the U-shaped manifold in the middle of the test stand.
The resolution is poor here on Youtube, but if you look closely at about 49 or 50 seconds, you'll see a vapour vortex form below the front of the intake and get sucked into the engine.
To those of us who were there, it was very dramatic, and looked like a rag going in.
Scary for just a second!
The outdoor shot shows a 1000 gal diesel tank which is used for testing liquid-fuelled engines.

Orenda 14 Turbojet in the shop

Uploaded on Oct 25, 2011
We've got a 50's fighter jet engine in the shop, so let's have a look at it.
This engine was among the first to mount the powered accessories on the outside of the engine instead of clustered inside a forward nose cone. To drive those accessories, a way was needed to transfer power from the main rotor out to the cases. We look closely at just how that was done.

It's been more than ten years of negotiations, but it's finally back in Canada ... in our shop.
This is the engine thought by many not to exist at all.
Sent to Bristol Aerospace for disassembly in 1958, it was never put back together, and stored in a giant warehouse in the UK. It escaped destruction, and sat for decades until it was put in a shipping container and sent to S&S Turbines in Fort St John BC.
The long term plan is to restore it to running condition, but it's going to take a great deal of very difficult work to get there...

Power Turbine Locked

Published on Feb 27, 2013
For an air seal test of an LM2500, we lock the output shaft of the intergral power turbine so it can't move.
First run we did not even get to idle before the unloaded and unlocked PT started to approach its full running speed.
We shut the engine down, and Byron built a locking fixture for the output shaft of the PT. Then we ran the engine to idle, and just above that to check VSV activation threshold.
Everything goes great.
The VSV tuning is bang on, and the air seal flow is in the range of what we want to see.
I didn't get much footage because I was on fuel purge and hookup duty, and I only had one camera.

Rolls Royce Olympus

uploaded on Feb 26, 2008
Test run: Rolls Royce Olympus at S&S Turbines open-air test cell.
One of the largest turbojet engines, about 40 thousand Hp in the industrial version shown here.
Looking in the front at startup, you can clearly see the freshly cleaned elements of the low-pressure compressor:
First are the struts, which hold the front main bearing firmly in place.
The LP rotating shaft is supported by this bearing.
Second, you see the copper-colored inlet guide vanes. On many engines these are able to move, but in the Olympus they are fixed.
Then the blades of the first stage of the turning compressor shaft.
They are made of solid titanium alloy, and it took 2 days to hand polish them.
Next, the first stage of compression is made complete by stator vanes, which are directly behind the spinning blades.
The Olympus is closely related to the engine used the Avro Vulcan Bomber, and a later, uprated version was used in the Concorde. Both used four engines, with afterburner on the Concorde. This engine does not have an afterburner.
This engine is used to generate electricity. A lot of it!

This Olympus was looking good as it hit all the marks and passed all the tests on its first try at the test cell in Fort St. John, BC.
Notice how much more slowly an industrial engine is powered up compared to an airliner engine... one of the reasons they last more than ten times longer between overhauls...
The smoke you see is common on the first runup after rebuild; it's sealants curing and assembly lube flashing off.

Rolls Royce Olympus V

Published on Dec 12, 2012
A strong wind flowing through our test cell is caused by this large turbojet, and makes it feel much colder than it is.

On the test day, we ran the engine for a total of about 45 minutes. We started and shut it down several times, made a few adjustments, and ran it at various power levels.
This clip is edited out of the parts of all of those runs that I was able to capture.
We fuelled it with propane vapor, which is a convenient substitute for natural gas, because we can store the liquid propane in a large tank, and vaporize it as we need it.
To deliver natural gas in quantity to fuel the engine, we would need to build a pipeline to our test cell.

Starting a large turbine engine

Uploaded on Aug 25, 2007
Start-up of a GE LM1500 at the S&S Turbines test cell.
This is an industrial version of the J-79 turbojet, which powers the F-104 Starfighter and the F-4 PhantomII. In those planes, it has an afterburner, but the LM1500 does not.
The LM1500 makes about 15,000 Hp at 7200 rpm, and often runs for months, sometimes years at full power, 24 hours a day, non-stop.
First you hear the electric starter of the turbine-powered start cart.
When fuel flow begins, flames shoot from its exhaust.
This is due to a dirty fuel nozzle, and isn't harmful.
Then you hear the start cart accelerate to full rpm, at which time you hear a whoosh, as it blows air through the large blue hose to the air starter of the 1500.
The 1500 begins to turn, and as it gets to about 2,000 rpm, fuel is introduced and the engine lights off. You can tell when this happens by the heat waves coming out of the nozzle, at the rear. Also, you hear the revs increase more quickly.
The 1500 starts to accelerate, and after it reaches self-sustaining rpm, the operator in the booth gives a signal to the technician, and the start cart is shut down.
The 1500 continues to accelerate until it stabilizes at about 5,000 rpm.
Now you have your basic, idling large gas turbine engine.
To see this same engine cranked up to full power, making about 15,000 Hp, check out the other video I made of it called "Turbine Engine: full power"
You'll notice the earmuffs... they are on top of earplugs, because these things are deafeningly loud. They roar out the back, but have a piercing scream from the compressor (front). The poor camera's mic was unprotected, and that may explain the distorted audio.
We tested a J79 with afterburner in Dec 2006, and you can see that here:

30,000 Hp GE Turbine engine

Uploaded on Feb 23, 2008
GE LM2500 turbine engine at the S&S Turbines test cell in Fort St John, BC.
This is an industrial version of the CF-6, which powered the DC-10 and some 747 aircraft.
Various marques of this engine produce between 25 and 35 thousand horsepower.
In the first shot, we are purging liquid propane from the fuel line. This fuel must be in a gas state for our controls to work properly.
The shot at the end is included just because I walk right through the flow of hot air still blowing out the exhaust as the engine winds down.

Funny, at the end of this clip, the Olympus is just above idle.

Avon Turbojet startup

The aero version of this engine was used to power the English Electric Lightning, a mach 2.5 interceptor in the 60's, and also the DeHavilland Comet airliner of the 50's.
An on-board electric starter is powered by 11 car batteries to bring the engine up to light-off.
When I hit the third position on the switch, that's 132VDC and 1000 Amps.
The current quickly drops to 50A, and stays there until I am signalled by Brian Maddigan, the operator, to cut power to the starter.
This test went well, and we made 23,000 Hp today.
All running footage here is of the engine at idle.
The roar of this thing is so tremendous that the vibration caused the camera to shut down. Unfortunately, much footage was lost.
I hope to have some full power footage in the future.

Jet Power : VERY LOUD!!

This was a successful test.
The video is long and possibly uninteresting to some, but a very gradual throttle-up is typical of industrial engines. I have had a few requests for a full, unedited spool-up, and here it is.

The compressor rotor of a jet engine can be damaged by the build-up of rust.
The blades can lock up in their slots, and then they may fracture due to increased vibration. Here we look at how rust can get into the blade roots of stainless steel blades in steel disks, and even in titanium alloy discs.

Airliner, or Fighter ? - Turbine Engines: A Closer Look

Uploaded on Oct 24, 2010
Due to the amazing level of knowledge posessed by you, the watchers of my videos, and your curiosity, we're going to look at the subtle differences in different versions of the same engine.
We're comparing the compressor outlet guide vanes of the J79 military engine and those of the CJ-805 commercial airliner engine. Both are essentially the same engine, and were the cutting edge back in the 50's and 60's.
The LM1500 industrial engine uses the aerodynamic components of the J79, and many are still operating today.
S&S Turbines, where this video was made, specializes in supporting the LM1500 and other industrial turbine engines.

The Timed Rundown - Turbine Engines: A Closer Look

Taking a look at exactly what a "can" is when you are talking about jet engines.
You want to know, so have a look at this bit of history.
In its day the Orenda type 14 turbojet was the most powerful in the world. Designed and built in Canada, eh!
Nothing lasts forever, and the American P&W J57 soon blew everything else out of the water in terms of power, weight, and flexibility... but things were brewing up north... stay tuned.

J79 Turbojet to VSXE-2

Uploaded on Nov 5, 2010
What was once a J79 installed in an F104 Starfighter has been reconfigured as an LM1500... but not just any industrial workhorse. This engine has been modified to allow running outside the nominal design paramaters for safe operation.
This experimental jet engine is running, literally. "outside the envelope".
This engine is a compilation of greatness, consisting of parts from a couple of J79s, and two LM1500s - a 101 and a 102, plus a couple of CJ805 bits!
Running on propane using special fuel nozzles hand-made by Lane McCabe.
We've also got control of the VSVs... independent of throttle.
If it's not exciting to watch, well... there's not enough room here to explain it all.
Those of you familiar with J79s or LM1500s will see it right away.
Yes: this test was successful.
And there's a cameo of none other than AgentJayZ warming his cold hands in the jetwash.

The Propane Dream Pt 3

It's been too long, but at last I can show you the conclusion of the propane dream. I've got the 6.0L cammed up and it's been through about 2500L of propane, while there has yet to be any progress made on Mr Bill's Vortec Chevy. He's still burning the black fuel.
It's been over a year since part two, but hey.. we've all been busy building jets and riding bikes.
... And when it finally happens... there will be a part 4 !

VSXE-2: The Second Day

Uploaded on Nov 9, 2010
Testing the upper range of power and airflow performance of our modified LM1500/J79/CJ805 turbine engine. It has parts from all three.
Normally, the variable stators and inlet guide vanes are always precisely controlled by computer to provide the most stable airflow at all compressor rotor speeds. This is to avoid stalling or surging of the engine.
This engine has been built to turn slower than the starting speed of a normal J79, as well as keeping the ability to achieve the same max power.
We have also programmed the computer to give independent control of the angle of the variable stators, regardless of RPM.
This very definitely makes it possible to cause a stall of the compressor, and a big one could cause a lot of damage to the engine, as you may notice from my comments in the control room.
The test went well: we exceeded our expectations, and we had no difficulties.
But the risk was there.
Over-riding the computer control of a 15 thousand Hp jet engine is not for the faint of heart, nor the weak of knee!
All went well, thanks to the skill of the man at the controls: Robin Sipe, founder of S&S Turbines in Fort St John, BC.

J47 Turbojet engine test run 1

Uploaded on May 12, 2011
You've watched it being built for weeks, and here it is running up to 96% rpm in our test cell.
These classic F-86 Sabre engines do spit some fire on startup, and here with slightly less volatile fuel, we have a bit more fire than is normal.
But at no time during the entire test sequence did this engine experience a temperature outside the normal range, as specified by the manufacturer.
I get Bill to open the fuel supply valve at 500 rpm, and I immediately switch on the ignitors.
At 600 rpm I crack open the throttle, and move it to START, which is about 1/8 to full.
The engine lights and spits flames out the tailpipe, so I cut back on the throttle, but too much, and the engine quits.
Of course the starter is still spinning it, so I advance again to START, and then pull back to about 1/16 and let the flames clear from the jetpipe.
I then slowly advance towards IDLE, which is near 1/4 throttle, and signal Byron to shut off the electric starter at 2100 rpm, which is the specified starter cutout speed.
I take about a minute to bring the revs up to 3000, which is nominal idle speed.
After idling for 8 minutes, I slowly bring the revs up to 7640, which is the nominal setting for 90% power.
The thrust you see displayed is about 30% low, because the tailpipe nozzle is nearly 100 square inches too large in area for this engine to make optimal thrust.
Overall, this engine performed well, and didn't leak a drop anywhere.
A successful test run !

The F-86 Sabre has two fuel regulators, main and emergency, enabling the pilot to fly the airplane in case all electrical power is lost. It also has dual independent fuel pumps, either of which will supply the engine with enough fuel for full power.
In this test both systems worked perfectly, and the hydromechanical automated EFR was more aggressive with the throttle than I was !

First LM1500 Test of 2013

Published on Feb 7, 2013
We have rebuilt our own lease engine, and we're almost ready to send it back out into service. But first we test run it, on this cold winter day.
Not too noticeable in the video, but this test begins with a bit of a hard light off - a small boom on ignition. No problem.
What appears to be the first start is actually a run-up on the starter with no fuel or ignition, and we are looking to see that there is oil pressure.
The engine is assembled "dry" and sometimes it takes a bit for the oil to start circulating...
After shutdown I try to disconnect the fuel line as quickly as possible, so the slight air pressure left in the engine will purge all the propane out of the fuel nozzles and manifold.

Turbine Engine: full power ... LOUD!

Uploaded on Sep 13, 2007
This is more film of the GE LM1500 gas turbine engine running at the S&S Turbines open-air test cell.
All the noise in the beginning is made by the start cart, which is a 90Hp turbine engine. Even when you hear the LM1500 start to wind up, it's not even running until you see the heat waves coming out the back of it.
This happens when the operator opens the fuel valve at around 2,000 rpm.
In the middle of the video, when the noise in an unbearable shriek, the engine is turning just over 7000 rpm, and is blowing hot air out the jetpipe to the tune of a little more than 15 thousand horsepower.
The air flow through the engine at full power is about 150 pounds per second.
In the view of the control room screen, the numbers are as follows from left to right along the top of the screen:
EGT or exhaust gas temperature in degrees Celsius, measured just after the last stage of the turbine, which is just behind the second green steel frame holding the engine.
Next is RPM. This engine has basically one rotating shaft, and you can just barely see the 1st stage compressor blades moving on shutdown. Engine RPM is of this common shaft, upon which all compressor and turbine stages are mounted.
5,000 rpm is idle speed for this engine.
Last, on the right, is lube oil pressure, in pounds per square inch. These engines have roller bearings, not journal bearings like a car engine, so oil pressure is mainly an indication of oil flow. A lot of flow is needed, because the oil is used as a coolant for the main bearings. The engine will run with no oil pressure, except the bearings will overheat, so monitoring of oil flow is very important.
This is the same engine you see in "Starting a large turbine engine"
Note: All references to podracers will be deleted.
If you have to ask why, it can't be explained to you.
