Grunting
away on a three-foot-long pipe wrench, Orenda Tech Rep Bud Bailey, says: "I'm
sure that we used to snug the fitting on, and then tighten it until it squeaked,
then one more turn." "No! No!" says WO Jim Miller, "You twist until the wrench
gets real hot, then one more turn" Bill Makarenko, looking on, says to himself:
I know darn well I should have stayed in Comox working on the Argus."
Corporal Tex
Gannon is quite happy after two weeks of searching for the start of a line
and has finally succeeded. This mass of wires, lines and piping is found on
a J79 engine. Blinded by the flash of our photographer, he lost the line and
is still in pursuit of the culprit.
Located in a large aluminum
shed at 4 Wing, this laboratory houses a couple of dozen technicians working
feverishly to keep up with the inspection cycle program
of the J 79 engine. This engine is a 17-foot long oversized contraption
which propels the Starfighters to abnormal speeds. This phase program which
comes under the Aircraft Repair Officer, Capt. Burt McCaughan, is masterminded
by WO Jim Miller and three senior sidekicks who supervise the operation.
Each engine undergoes a 3-week rest period, where they are disrobed of their
components, disassembled from back to front, and every inch scrutinized.
The engine itself is composed of a large compressor and turbine, as well
as the several hundred lines, tubing and wires that resemble spaghetti thrown
out of a bowl. When you put this together with pumps and other accessories,
the result is the driving force behind those whining man-made birds with
which we are so familiar. When one sees the engine all apart, it becomes
hard to imagine it in one functioning piece again. But it does, the technicians
are willing and competent and nothing is left undone. The J79 is a complicated
engine
The principle
of a jet engine is explained here by the applied blow torch principle. Corporal
Gord Peckett blows a mixture of left-over oxygen and Loewenbrau fumes into
a combustion liner held by Ray Lavoie, while George Young adds the necessary
fuel to the liner. The results after ignition, if blown hard enough, will
be an ensuing thrust which will turn the turbine wheel. If not, they all get
their hair singed.
and
has several sysstem
integrated within its innards which are vital to its operation,
Today's most modern technique has been adapted to the inspection in the form
of oil analysis of the lubrication system. This method is to detect and determine
the source or origin of microscopic sized metallic particles found within
the lubricating system. The type of metallic substance found is recorded,
and when a pre-determined safety factor has been reached, precautionary measures
are then taken as to which component is likely to fail or cause a failure.
A representative from Orenda Engines Limited, Mr. Bud Bailey, keeps our staff
informed on the technical aspect of
the engine,
as
well as advising them on problems encountered
After re-assembly by the inspection crew, during which several pounds of locking
wire have been used to hold everything together, the engine undergoes a series
of test run-ups by a test cell crew. Final tune-up adjustments are made and
then the engine is reissued to an awaiting aircraft.
The workload never ceases, as one can judge by the sound of the deafening
shrills of the 104s in the European skies. The motto at the Lab is: "be tune
them, you fly them.
Indeed they are tuned, and will be flying for awhile yet!!
During your
tour of duty in Germany, you'll find:
People who will sell you a car. People who will sell you a car and finance
it.
People who will sell you a car, finance it, and insure it.
At first si9ht, this seems all very convenient for the car buyer. We maintain,
however, that the field of insurance is best served by specialists.
The law demands that you are insured, and leaves it at that. We not only issue
your policy . . . we back it up by a team of experts. Everything you might
wish to know . . . explanation of the fine print . . . what your rights are
when claiming . . . all these are part of the service which 9oes with your
policy.
And when returning to Canada ...We provide your PINK CARD and policy
through Servicemen's Automobile Club.
We insure your Car and Luggage for shipment through
ELVIA Versicherungs-Gesellschaft in Zürich (Switzerland) at adequate
rates and with first class claim service.
