"In this connection I would like to pay tribute
to my colleagues, Mr. J. C. Floyd, Vice-President
of Engineering and Mr, H. R. Smith, Vice-President
of Manufacturing, who have headed up their teams
so admirably.
"I would also like to pay tribute to the Canadian government agencies with
whom we have worked so closely, and who have made such great contributions to
this project. In particular, of course, I refer to the Royal Canadian Air Force,
and to its staff of able technicians and engineers.
"I would also like to make mention of the National Research Council, who
have assisted in many technical areas, and particularly in the use of their wind
tunnel and other test facilities.
DDP Helpful Partner
"The Department of Defence Production
has also been a most helpful partner in this undertaking,
and is ever ready to assist with our problems which
arise in the sphere of their responsibility.
"The Defence Research Board has likewise contributed its assistance in advice
on technical problems, and greatly assisted the very important free flight model
test programme which was carried out at one of their facilities.
"We also wish to say `thank you' to the United States Air Force and to the
National Advisory Committee on Aeronautics for the co-operation and assistance
which they have always been so free in offering.
Subcontractors
"Whereas the Arrow is an Avro product,
and whereas we are responsible for the overall
design and manufacture of the aircraft, we could
be considered, let us say, as the captain of a
team of hundreds of suppliers and sub-contractors
who, together with us, did this job. |
"There are many companies who have
made outstanding technical contributions in the design,
development and manufacture of all types of equipment
and material for the aircraft. To them I wish to expressour
deep appreciation and gratitude. The first aeroplane
which you will see today, and the next few development
aircraft will be powered with the Pratt & Whitney
J.75 engine. However, the ultimate engine to power
the balance of the development aircraft, and all the
production aircraft, is the recently unveiled Iroquois,
designed by our associate company, Orenda Engines Limited.
"As we have been creating the Arrow,
they have been creating the Iroquois. This
engine too represents a milestone in Canadian
industrial accomplishment, and it is the
thrust of this engine on which the very
advanced performance of the Arrow will
depend.
"At the close of this ceremony, the
aircraft will be taken to the flight test
hanger for flight preparation, which will
involve exhaustive testing and the installation
of extensive, specialized instrumentation.
The flight date of the aircraft will depend
on the problems which will have to be dealt
with during this phase of the programme
and, consequently, it is difficult to foretell.
We are hopeful, however, that the aircraft
will make its first flight before the end
of the year.
Flight Test Program
"Behind this first aircraft there
are other development aircraft in various
stages of completion, and all of which
will be subjected to an extensive and time
consuming flight test and development programme. We
know that, like all other aircraft of this
type, where one is constantly probing the
unknown, we will encounter many problems
and setbacks and it will not be until this
exhaustive testing is successfully concluded
and until the development phase of the
programme has been accomplished, that it
will be able to see service in the squadrons
of the Royal Canadian Air Force. |
"The CF100, which is currently in
production for the Royal Canadian Air Force and the
Belgian Air Force, was created,designed, developed
and produced here at Malton. We like to feel that that
aircraft has played an important role in the defence
of our country and has contributed to NATO. It is our
fervent hope that, in due course, the Arrow will make
the same contribution in the supersonic era in service
with the Royal Canadian Air Force and with the air
forces of other allied countries.
"In closing, I would like to again thank
the Royal Canadian Air Force and the Government
of Canada for affording us the opportunity of designing
both of these aircraft, and for entrusting to us
this responsibility, of which we are so deeply
conscious."
Precision Keynotes All Arrow Tooling

for the processing of the many lar e pieces of
material required for Arrow part manufacturing.
Immediately below the hot air circulating furnace,
which is mounted on legs, is a 20-foot-long quench
bath. This set-up means a minimum of time is spent
in the transfer of material from the furnace to
the quench.
To meet strength specifications where parts were
joined together with the metal bondin technique,
an autoclave pressure camber was installed. Where
metal bonding of materials is used on the Arrow
it gives a high degree of adhesive strength as
well as a weight saving factor due to the elimination
of rivets and other dowel-type fasteners.
Due to the weight of many of the Arrow components,
and the accuracy required in their assembly, a
final assembly fixture was provided so that all
of the large components could be brought together
accurately at one stage.
Methods to establish working flexibility of assembly
jigs were developed along with standardization
of jig fixtures where possible which added to a
more efficient tooling program.
