one of the winter mods will be to enlarge the fresh air intakes.
see the restriction.

Turbines can generate massive torque.
Something else to consider is when you throttle a turbine and pull back on the sticks
it does not close butterfly's and slow down the way a piston engine does it spools down.
This kinetic energy shows up in all kinds of fun things like.

What was the original use / or intention, of these engines? I'm assuming aircraft as it has the de icing system but do you know what the bird was? Is this your first foray into hands on this deep into one of the powerplants? They look so simple on paper and to see it all coming apart is an interesting follow. You've inspired me to reset the time on cars clock from daylight savings. Thanks.

lol
the t53 is out of a huey helicopter
the 703 version is out of the cobra helicopter
the t55 not shown in this thread is out of the chinook twin rotor helicopter

Thanks for a very informative thread, love the detailed pictures and descriptions that you've given through out the process... We work around aero-derivative and large frame turbines all the time but not on them. Just providing fire & gas suppression protection packages for them incase something goes wrong... Jim

Nice website i just checked it out!
leads me to start to consider a upgraded fire suppression system.

ok the tools are here.

Jim took the time to label what everything is for so basically any froot loop can do it.

we install the shaft plug as not to damage the shaft threads
also remove the locking tabs by peeling them back then remove the 6 nuts... i
numbered each one for installation. These are all part of a balanced assembly.

its only piloted approx 3/8 so it came off pretty easy.
this is called the second GP rotor.

here is a shot with the second gp rotor now removed.
We are looking at the second gp nozzle now.
