Jet Engine Starting: Cockpit vs Test Cell

How we start a turbojet engine in our test cell compared to how it's done in the aircraft.
The Orenda 10 (Canadair Sabre Mk 5) and the Orenda 14 (Canadair Sabre Mk 6) are so similar in construction that it really makes no difference to our demonstration here, and the starting procedure is exactly the same.

I still remember starting my first jet engine way back in 1997. I was a 18yr old 3rd year apprentice and my boss entrusted me to fire up two GE CF-6-80C2's on a Qantas Boeing 767-300. What a rush for a young bloke! And I'm happy to report I didn't melt anything. 😁

Hey Jay Z, I flew two Century Series aircraft. The F-102A, T-33 and T-33AT which was the attack version. The F-102 was famous for compressor stalls. You could not throttle burst it while stationary. These were not big stalls and we called them choo choo stalls which sounded like someone pounding a hammer on the fuselage. All you had to do was slow down your throttle a tiny bit. Startup was not computer controlled like today's jets. The F-102 had an air turbine starter. You needed a ground power cart. The drill was spin, spark and then spray. Same with the T-33 except it had a starter generator. I now instruct in a Cessna Grand Caravan with a Canadian built PW PT-6A engine. This is only simulator but has a real cockpit, motion and sound with Garmin 1000 display. You are actually in a CRV. I also flew for 8 years in the Dornier 328 which had PW 119B engines. What a beautiful engine. You guys up there in the north do great work. BTW j Z, I'm not sure where you are but Ottawa was one of me best overnights.

[@tylerkrug7719]

[@joevignolor4u949]

When I was in the Air National Guard we had F-100's with J-57's in them. We didn't have a test cell. We had to taxi or tow the F-100 with the tail removed out to a pad and chain the airplane down to test the engine. The hydraulic lines going to the tail had to be capped off in order to pressurize the hydraulic system. In the winter time we used to throw snowballs into the flame when the engine was in afterburner. And it was nice to stand close to it on a cold winter's day.

[@AgentJayZ]

Awfully sorry, chap, but I get a comment like this every week. And my response is always the same: Could you even tell the difference between a J58 and a J79? Both are large afterburning turbojets that propel aircraft in excess of Mach 2.5. The bypass tubes that make the J58 a ramjet can obviously not be tested during a static test. The J58 is a useless engine that no longer has any purpose. Many J79s are flying today, and many examples of its industrial derivative are also running. If a J79 really isn't enough for you, then you are respectfully asked to leave immediately.

I've told this story on this channel more than once but, back in 1982 (or was it '83?), I was walking out through the main foyer of Whittle House, Bristol, on my way to lunch. I was in conversation with a colleague and let the glass door close behind me, only to hear a growl of disapproval. We looked back and, with embarrassment, we both said in unison, "Sorry, Sir Stanley!" However, I digress. I was rather non-committal with my previous reply, but I've now had another, more detailed scan. I can find no comment about SGH being involved with Svenska Flymotor and the RM6, which was a licence-built Avon RA.29, designed in the 1950s. Hooker was heavily involved with Avon development during 1947 and '48: it was the root cause of his row with Ernest Hives and his departure for Bristol Aeroplane's Engine Division. When the RA.29 was being designed at Derby, he would have been busy with the Proteus and Olympus at Bristol. PS: Tightening some tolerances (eg, tip clearances) would, at best, only have a second-order effect on engine performance. It would need a tweak to the aerodynamics to produce a significant improvement in the performance.

Really good idea using the cockpit to illustrate the start procedure. Also, while contested on a "technical basis", George Welsh (not Chuck Yeager) was actually the 1st person to exceed the speed of sound while flying the XP86 (test bed for the F86). The "technical" matter is that the Bell X1 flight (10/14/1947) was a "certified flight", with all data gathering equipment applied, while Welsh's flight was not certified for "all" regimes. Also, Welsh's flight angle was slightly nose down, while Yeager's flight was in a level attitude. Later, Jackie Cochran was the 1st female pilot to break the sound barrier while flying a "Canadian built" (tada-tada-tada) F86.

Throttle lever outboard for ignition & boost pump - if its anything like the A-4, there is a small micro switch that the throttle hits on the outboard slide that activates these. In the A-4 we "came around the horn" at 15% N1 to introduce fuel and start the igniters. If we didnt 'bang' the throttle outboard there was a chance we missed the micro switch, resulting in a wet start.

[@triroo107]

Dave Souza , you are correct, around the horn.... brings back so many memories doing engine turns. “Go around the horn like a man” was how I was taught, take throttle all the way up and then back to down and start counting for lite off. Oh to be 20 something again

[@threeparots1]

Only similar sized engine (turbo shaft) with similar production numbers would be the RR250, but I am always shocked how these don’t fail that often as their parts seem so stressed and the design while a compact package has several point points (peashooter o-ring, number 5 bearing) where if installed wrong or of they fail....it stops...seen a number 5 bearing where the bearing race had come apart and surprisingly they engine got them safely down somehow. PT6 parts seem so much more robust (bearings especially) and seem to pass overhaul inspection more frequently. Hot section repair is somewhat simpler too.

[@AgentJayZ]

RR 250 started out as a 320 Hp helicopter engine, and has grown to over 750 Hp. It is a hugely successful engine. PT6 started out as a 550 Hp turboprop for light aircraft. It has grown to almost 2000 Hp. It is a monstrously hugely successful engine. The two are at the top of their game, have been for decades, and are not in competition at all. They are both great.

@@fps079 I'm not at all surprised, as I would expect the F100 to have a Titanium fan and Titanium front stages in the HP compressor.

Hi, my name's Tuan from Vietnam. Your skill about jet engines really suprises me much. The jet engine or plane technology is forbidden in Vietnam. Hope you stay safe and healthy, teacher

...well, crank that Sabre up and get FLYING!

[@daneilsteenkamp6886]

Cool. A South African Airforce Sabre from 1 Squadron!

[@Stinkymole]

The Draken engines, I'm assuming they are RR Avons licence built by Volvo Flygmotor in Sweden? Do those examples you have there have the Swedish designed afterburner section fitted?

[@Strothy2]

Would love to see this test in person, hope you will share it with us!

[@wdcjunk]

I’m surprised with the frequency of service, the duration these engines and the company have been around that y’all don’t make pigtail adapters for the engines. I’d assume there is some uniformity at least from the aviation engines. Do you see variance in pin outs from the industrial variants? Are we talking 200 wires or 50?

[@AgentJayZ]

Each mark number of engine, matched to it's particular mark number of aircraft, is different from the others. We have a plug and play harness adapter for the J79-17, because we see a lot of them. It would not work, for example, with a -19 or a -15. Industrial engines do not have a wiring harness that is anything like an aircraft engine.

i was test cell qual'ed and was getting checked out in the cockpit to run the j79 before i went to i level maintance in the navy f4 forever

[@zapfanzapfan]

Does the manual say anything about service intervals or engine life time depending on use of MIL vs. only nominal?

Hi Jay. In the 90’s I lived in Edmonton. There was a farm in between Spruce Grove and Stoney Plain on HWY 16X. Now on that farm was an old Quonset and behind that Quonset was what I believe was one of those jets! I so wish I had went and talked with that fella as the farm is gone and a tractor sales shop sits in its place. Do you happen to know anything about that plane?
