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"

If you have to ask why, it can't be explained to you.
J79 - Turbine Engines: A Closer Look
A guided tour of the J79 turbojet
engine, from intake to afterburner. This is the cutaway display we have in
front of our shop at S&S Turbine Services, where we overhaul and repair
industrial gas turbine engines for customers all over the world.
Testing a GE J79 with afterburner
A newly rebuilt engine from a supersonic fighter is put to the test at the
S&S / Maddex test cell. After some run-ups from idle to full military
power, the afterburner is engaged, resulting in some extreme camera
Afterburner vs. Snow
We test run a J79-J1E with afterburner on a sunny, snowy, freezing cold
day. There are a few new people with us, and they prove that "everybody
loves afterburners !"
1) - Ignitors...
2) - Blade tip clearance
3) - Propfans?...
4) - 737 flattened inlet shape
5) - Rocket engines at S&S...
6) - J44 and the Motorlet 601
Sabre Jet Engine: first start
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
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".

Awesome V12 Monster diesel engine Awake and Alive startup
The first V-type engine (a 2-cylinder vee twin) was built in 1889 by
Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being
produced for motor boat racing by the Société Antoinette to designs by
Léon Levavasseur, building on experience gained with in-line four-cylinder
engines. In 1904, the Putney Motor Works completed a new V12 marine racing
engine -- the first V12 engine produced for any purpose. Known as the
'Craig-Dörwald' engine after Putney's founding partners, the engine
mounted pairs of L-head cylinders at a 90 degree included angle on an
aluminium crankcase, using the same cylinder pairs that powered the
company's standard 2-cylinder car. A single camshaft mounted in the central
vee operated the valves directly. As in many marine engines, the camshaft
could be slid longitudinally to engage a second set of cams, giving valve
timing that reversed the engine's rotation to achieve astern propulsion.
"Starting is by pumping a charge into each cylinder and switching on the
trembler coils. A sliding camshaft gave direct reversing. The camshaft has
fluted webs and main bearings in graduated thickness from the largest at
the flywheel end." Displacing 1,119.9 cuin (18,352 cc) (bore and stroke
of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg)
and developed 150 bhp (110 kW). Little is known of the engine's
achievements in the 40-foot hull for which it was intended, while a scheme
to use the engine to power heavy freight vehicles never came to
fruition. One V12 Dörwald marine engine was found still running in a
Hong Kong junk in the late-1960s.
Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb
Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc
(5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV.
It weighed in at 2,114 pounds (959 kg). No weight is known for the massive
3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built
by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300
By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x
254 mm)) engines with four-valve cylinder heads the V12 was well
established in motor boat racing.
In automobiles, V12 engines have not been common due to their complexity
and cost. They are used almost exclusively in expensive sports and luxury
cars because of their power, smoother operation and distinctive sound.

focused on the nº2 engine to record how much time needed a CFM 56 engine
to completely stop. Recorded at Barcelona - El Prat airport (LEBL).
