| The Avon I have
is a Mk 122 which is from a single seater Hawker Hunter
aircraft which was started by explosive cartridge. It
was decommissioned in 1992 with just over 30 hours flight
time. Weighing at just over a Ton and producing in the
range of 10,000 Lbs of thrust this is going to be a fun
project.

Here's my Avon
at the storage facility, I have to thank my friend, Paul
Davidson for his advice on this engine as well as Keith
Smith, the nice chap that is selling it. As you can see
its all bagged up and covered with Silicon beads to absorb
the dampness that forms in the bag. Cant wait to get it
home. |

| My second most
popular view of a gas turbine engine - the Inlet, this
image shows the variable Inlet guide vanes.
|
|
My favorite view of a gas turbine.
The business end! Have you ever seen such a beautiful turbine
wheel? I know I need to get a life, as I'm told daily by
my girlfriend.

Loaded on the
trailer and ready to do the 4 hour journey home to shropshire.
No problems on the way back, just had to take it easy,
fuel consumption on the 4x4 was up lots as you would expect.
|
|
Now back at home
the first job is to remove the cartridge starter shroud
so that the new electric starter shroud can be fitted.
I have to say that this was quite a mucky job as the residue
form the propellant forms a sticky black gunge.

|
|
This image
shows the assy in pieces. The exhaust tubes and outer
frame will still be used and I will probably make a waster
paper bin for the office with the shroud.
|
|
Now you can see
the transportation blanking plate. Once removed this is
where the starter will be bolted to. The cable with the
red cap is the cartridge igniter loom which will no longer
be used. |
|
|
|
This is
the reverse side of the blanking plate showing the gear
adapter which will be removed and bolted on to the starter
motor spline. This is on the blanking plate to stop the
turbine rotating while in transit as it locks the gear
assy up.

A view of the
epicyclic ratchet assy that mates with the starter. |

|
|
This is
what a brand new 50 year old starter motor looks like
when bolted on to the Avon without the covering shroud.
For its size, its a really heavy piece of kit.
|
|
Electric starter
shroud fitted, though a proper internal fixing plate will
still have to be fabricated to hold it in place , a job
for another day. |
|
|
|
Nose cone fitted, looks like
a battle ship shell bolted on to the end, What a size!!
|
|
This is a minor
cause of concern for me as there is a small feather stuck
in the side of one of the inlet guide vanes. There is
no apparent damage to the blades, but I presume that the
engine has had a bird strike. I would imagine that it
would have been a small bird, possibly like a blue tit
or something similar.
