Jan Zurakowski
B 1914-D 2004 |
|
Jan (Zura) Zurakowski was born in 1914 to an ethnically Polish
family in what was then part of Russia. His father was a doctor
and once the Soviets seized power, he feared for his well-being,
and that of his family since the Communists were eradicating
the "intelligentsia." Thus in 1921 the Zurakowskis,
posing as peasants, managed to escape to the newly independent
Poland.
Jan learned to fly gliders in High School and later joined the
Polish Air Force. While in flying school, he met Anna. She must
have made quite an impression on him (and visa-versa!) since
despite the history that was shortly to unfold, they would eventually
re-unite and marry once she was able to escape Soviet Poland.
Six months before the Nazi invasion of Poland, and the beginning
of WW II, Janusz was posted to a training Squadron on Pzl-7's
as an instructor.
When the Germans attacked, Jan was part of a three aircraft
formation of the out-moded Pzl-7's trying to shoot down the very
fast Dornier Do-17's engaged in bombing operations. The Dorniers
simply edged up the power when the Pzl's were spotted and outpaced
them. Ever cagey, Janusz learned from the mistakes and began
to try to approach the formations alone, to either escape detection,
or perhaps hoping they simply wouldn't run from a sole attacker,
on a third attempt, Jan managed to close unseen on a formation.
He opened fire but the return fire was accurate and he broke
off his attack. The Pzl-7, being a trainer, used 2 WW I vintage
Vickers machine guns with poor (time-expired) ammunition. By
the time he was under fire both of his guns had jammed. While
evading the German fire, he cleared both guns (the breeches were
inside the cockpit) and managed to again get into a position
to fire. He managed to score hits on the last German aircraft
in the formation and the smoke trail left by the Dornier indicated
he had damaged it. This would be Jan's first victory of the War.
Jan and a good deal more Polish pilots escaped from Poland when
the Nazi victory was apparent, to France. Still later, this nucleus
of pilots arrived in Britain.
The Battle of Britain
Jan would fly with several Spitfire Squadrons and command 316
Squadron. His intelligence, dedication and skill also meant that
he would be used as a valuable liason and staff officer. This
certainly undercut his flying hours. Despite these demands, Jan
would be credited with 3 destroyed, and 1 probable during the
Battle of Britain.
Janusz stated that the early Spitfire's were a
very specifically designed aircraft leaving little allowance
for other roles, or indeed comfort. (Today we would consider
this designing to a single-design point.) An example he gave
of this was its lack of a windscreen defroster. On one engagement
he had been chasing a Bf-109. The usual German tactic when faced
by a British fighter was to dive since the early British Merlin
engine carburetors would cut out under zero "G". The
Messerschmitt was also somewhat faster at least in the initial
portion of the dive. As Jan dived after the German, his windshield
iced up completely due to the temperature and humidity differential
at altitude compared to lower down. Despite this, he closed on
the German to where he could see the wing-tips of the enemy aircraft
through the side panels of his canopy, (VERY CLOSE!) and opened
fire. The 109 crashed into the sea close to shore.
While serving with 316 (Polish) Squadron as a Flight Commander,
Jan met “Spud” Potocki. Jan mentioned during our interview thinking
at the time that Spud was easily the best pilot on the Squadron
and remembered him later.
Jet Age Test Pilot
Jan's exceptional flying ability ensured he was on the second-ever
Empire Test Pilots' course in Britain in 1944 and in 1945 he
began testing the Vampire Jet Fighter at Boscombe Down. Postwar
he was hired by Gloster's as Chief Experimental pilot on the
Gloster Meteor with Bill Waterton, a Canadian from Alberta who
was Gloster's chief test pilot being his boss. (Waterton was
the first pilot to fly the Avro CF-100.)
Always an enthusiastic aerobatic pilot, Jan was often called
upon to do air show demonstrations of the new military hardware.
In 1946 he gave a dazzling display of the Martin-Baker MB-5 at
the first Farnborough air show earning raves in the press and
other media. Not all Jan's experiences were happy however. While
demonstrating the de Havilland Vampire for a Russian delegation
(and in front of many RAF brass!) Jan experienced a phenomenon
that plagued early jets (especially) referred to as the "box".
At low speeds, the drag increases rapidly as the angle of attack
is raised to provide enough lift. This can soon exceed the power
of the engine and only putting the nose down to gain airspeed
will prevent a stall. While doing a low and slow pass, partly
due to the slow rate of power increase on early jets, Jan entered
the box. Quite gently the aircraft, howling at full power, settled
the last few feet to the runway and came to an embarrassing and
grinding halt. Jan walked away from the not-badly damaged aircraft
with an undoubtedly chagrined look on his face. Once can only
imagine the grins of the Russians, and scowls of the British!
While test flying the Meteor, Jan also developed the first new
aerobatic manoever in about 20 years termed the "Zurabatic
Cartwheel". The story goes that sometimes during exceedingly
tedious "lectures" and wrangling meetings with the
engineers, his mind would drift to aerobatics. A new test of
the Meteor ground-attack version involved carrying four bombs
far out on wings of the Meteor. Jan realized that with the weight
of the engines so far out from centre on the Meteor, that this
would cause some interesting effects if one engine was cut while
the other was at full power. Taking his slide rule from his pocket,
he spun up some numbers and concluded that something unheard
of might be accomplished.
He soon put his theory to the test in the air. With a late model
Meteor, loaded with these bombs, Jan put the nose down at full
power, then pulled to the vertical. Nearing zero airspeed he
simultaneously cut one engine, and kicked full rudder into the
dead one, leaving the other at full howling power. The asymetric
thrust, coupled with the inertia provided by the bomb weight
so far out on the wings, made the Meteor rotate on its side through
a complete one and one-half turns, ending up doing a cartwheel
laterally and pointing down at the ground. Needless to say this
was a real crowd-pleaser and gained “Zura” real fame.
Later he met his old Squadron-Mate Spud Potocki who was still
in the RAF as a test pilot at Boscombe Down. When he mentioned
his new trick to Spud, Spud's reply was something of a reference
to cattle excrement. Jan was thus forced to prove the point at
the 1951 Farnborough Air Show. That particular display is one
of the most legendary performances ever to be witnessed at this
world-renowned event. Jan commented to the author that Spud,
as an RAF test pilot testing the Avro Vulcan Bomber alongside
Avro's Chief Test Pilot, so impressed Avro's boss Sir Roy Dobson
with his report on a near disaster, that Dobson worked to have
Spud hired. Jan stated that Spud's skill and grace under pressure
that saved the prototype. The loss of Avro's only Vulcan at this
stage in its development may well have resulted in the cancellation
of what became a fine aircraft, and the longest serving of the "Victory" series
bombers. He also mentioned that test pilots were paid less than
Potocki was making as a new Squadron Leader, or even commercial
pilots flying DC-3's for Trans Canada Airlines (TCA, now Air
Canada). Spud insisted on a decent wage and thereby did all of
the test pilots a favour by improving their salaries.
During his time test flying in England Jan flew most British
types and many foreign aircraft. Spitfires of every Mark and
configuration, most of the early jets and he did aircraft carrier
landing with Seafires, Sea Furies, and most of the American types
as well. He also investigated the puzzling fact that the Seafire,
although superior aerodynamically to Hellcats and Corsairs, got
worse fuel economy. They eventually attributed this to the fact
that Rolls Royce had designed the Merlin with too long a piston
stroke to bore ratio done by the engineers as a relic of practice
brought on by a quirk in the British fuel taxation practice!
This poor fuel economy with the Merlin also plagued the Canadiar
North Star airliner when it went into service with TCA and some
other carriers.
While test flying at Gloster's Jan was involved in the development
of the Gloster Javelin. By this time he was becoming increasingly
frustrated with the propensity of some engineers to specific
test-flights designed not to show the shortcomings
of their design, and to assume that test-pilots were something
of glamour seeking dullards with little to offer the design process.
(Bill Waterton left Glosters later for similar reasons, and one
Gloster test pilot was killed due to this problem.) The Javelin
brought the danger of this line of reasoning into sharp focus.
Jan knew from flying this aircraft that it was unstable in pitch
at certain speeds and angles of attack. He also knew that in
service, this could easily cost lives. He requested permission
to prove this point and was flatly refused. All the test flights
were designed to show the plane to be a smooth handling speedy
wonder. During one flight with a Javelin equipped with flight
recorders and cameras, Jan disobeyed his orders and took the
aircraft to 400 kts, and eased back the stick increasing "G" force
and angle of attack (alpha). Quite soon the tail was completely
blanked by the large fuselage and wing becoming entirely ineffective
in pitch or yaw control due to the turbulence and disturbed airflow.
He pushed the stick full forward and the aircraft would not respond,
continuing its climb right to the stall and resultant spin. As
the aircraft spun and fell from the sky, finally, at lower altitude
where the air is denser, he was able to recover it. The cameras,
and flight recorders and indeed his detailed test flight report and
predictions clearly illustrated the problem. To Jan's horror
and disgust, the engineers re-wrote his report claiming it was
a successful test flight with stall recovery being explored!
Jan mentioned to the author his having suggested to the company
President that a few hundred pounds more a year would hire them
a competent aerodynamicist. Apparently the President wasn't entirely
receptive to his test-pilot's advice. Jan soon handed in his
resignation and in 1952, secured employment at what was then
the talk of the aerospace community, Avro Canada.
To Canada
Contrary to the impression left by the CBC mini-series on the
Avro Arrow, Jan Zurakowski was a part of the Avro team long in
advance of either the Arrow, or Jack Woodman (who was a fine
man and excellent pilot). Indeed Jack Woodman was on the RCAF
payroll, not Avro's, and was there only to verify Avro's flight
test figures, and to provide the RCAF with an independent viewpoint
of the Arrow's progress. Jan did a great deal of the experimental
test flying of the CF-100, Avro's second indigenous design to
fly after the impressive C-102 Jetliner (the first jet passenger
aircraft to fly in North America by several years!). Jan considered
the CF-100 a fine design and indeed, to be the most memorable
part of his flying career, perhaps due to his important contributions
to the development of this aircraft!
The aircraft was also exploring new frontiers in many areas
of science and technology. Jan and the other tests pilots' job
was to explore the aerodynamic and performance regions. Jan knew
this aircraft was capable of exceeding its published “do not
exceed speed” of Mach .85. He asked the engineers what would
happen if this speed was exceeded to which the reply was a curt "it
would become uncontrollable, and besides, the pilot's manual clearly states
not to exceed Mach .85.” Jan knew with the high thrust of Avro's
Orenda engines, and the sleekness of the aircraft, that eventually
a service pilot would exceed this limit. He considered it his
duty to investigate the possible result (and probably to find
out if Avro engineers suffered from the same problem as Gloster's).
At altitude and full power he nosed it into a dive –aiming the
aircraft right at an office at Malton where a conference was
underway among senior Avro engineers where they were discussing
if the CF-100 could possibly break the sound barrier under any
circumstances! A sonic boom crashing through the window of this
office provided sufficient proof to allow them to adjourn the
meeting! He was able to fight the stiff controls and recover
the aircraft from the dive. Evidence suggests that the tail was
overstressed by this however the aircraft held together in a
region where so many aircraft had disintegrated (including some
designed to go supersonic). As another example, Jan mentioned
having flown a Meteor at Gloster's with a specific shaped bomb
that induced such turbulence at normal speed that the control
surfaces disintegrated!
Obviously proving the CF-100 could survive “inadvertant” supersonic
flight was a bonus for pilots of the CF-100 and the company by
showing the integrity of the design. Since Avro was at the time
trying to sell a transonic redesign of the CF-100 (the C-103),
some Avro executives did not see it that way at the time. On
the other hand, the C-103 problems really taught Avro an enormous
amount about the area-rule phenomenon, and this held them in
very good stead on the Arrow project.
Jan did have the sad occasion to fly an early test CF-100 (testing
the ventral, retractable rocket pack installation) that failed
in flight. Due some internal explosion (perhaps a rocket that
misfired inside the aircraft) his back-seater's seat jammed due
to damage to the rails from the internal explosion and he was
unable to eject. This is a source of ongoing remorse for Janusz.
Jan also demonstrated the CF-100 at Farnborough Air Show in
1955. It had been scheduled to appear four years earlier but
development problems had held things up, as had installation
of radar and armament. Even so, the CF-100 was the first foreign-designed
aircraft invited to display at Farnborough. The CF-100 was incapable
of the Zurabatic Cartwheel due to the close spacing of its engines
however a spectacular falling leaf display, and tight aerobatics
at low level within the confines of the airfield dazzled the
audience. In part because of this performance, Belgium eventually
purchased CF-100's. Jan mentioned having spoken to the Belgian
delegation at the show and their mentioning that they had been
displeased with an American, and a British design they had bought
earlier and thought they might have better luck in dealing with
the Canadian manufacturer. By the time Belgium acquired the CF-100
(1958) the design was almost obsolete however Jan says the Belgians
were very pleased with both the performance, and reliability
of the CF-100. RCAF pilots insist it was easily the best (if
not only) true all weather/day-night interceptor in Europe in
the 1950's and indeed superior in flying performance to most day fighters
(except the Canadair Sabres). This was probably the reason NATO
asked Canada to augment their day fighter commitment in 1955
with CF-100's to fill a glaring gap in NATO's all-weather and
night defences.
The CF-105 Arrow
Jan's name is indelibly attached to the Arrow and indeed was
the first and only aircraft Jan would skipper on its maiden flight.
Although
technically too old for "high performance" flying,
(the limit then was 40 years of age) Jan continued flying on
the Arrow until he was 44. Spud then took over most test flights.
Jan stated the Arrow handled beautifully. Considering the low
wing loading, extremely high thrust to weight ratio and very
low drag of the airframe, even when loaded, indicate that the
Arrow would have been an exceptionally maneuverable aircraft
contrary to the opinion of many “experts.” The famous American
test-pilot, Chuck Yeager, is on the record as saying that he
felt the delta arrangement made for the most “unsurpassed” manoeuvrability
.
Janusz left Avro and opened Kartuzy Lodge with his wife Anna near
Barrys Bay Ontario and resides there still. During this period
he experimented with canoe, kayak, powerboat and sailboats of his
own design and manufacture.
