[VINTAGE SKY] Hi!
Today an episode about 1939 defender
the Polish PZL P.11 fighter.
It represents fighter serie
designed by eng. Zygmunt Puławski.
They all feature distinctive
"Polish wing" or "Puławski's wing".
This wing
was meant to provide pilot
with the best visibility.
The view is least obstructed
when we look at the wing
from behind.
Wing was at pilot's eye level
and was thinner and
bent downwards in front of the cockpit.
This design was patented
in 1931 as:
"High-wing airframe wing, distinctive by
being bent down by the fuselage
so that center-wing is
at the level or below the lower wing surface".
A gullwing shape.
Puławski died aged 29
in a test flight crash
of PZL-12 hydroplane he designed.
P.11 prototype was
first flown 4 months later
by Bolesław Orliński.
P.11 was developed from P.7
(its predecessor)
and the differences are minimal.
P.7 is above, P.11 below.
There were different details
but the concept was the same.
For the P.11
various engines were considered
(410-610 HP)
as well as several, mainly fixed propellers
This modern plane was widely advertised.
It was displayed in Paris,
Bucharest, Lisbon, Milan,
Stockholm and Sofia.
It would also enter races and competitions.
It won a contest
for the best fighter in Turkey.
In Zurich race it was second
only to Hawker Fury
which was faster by 8km/h
and was a base for the Hurricane design.
P.11 also competed
in National Air Races
in Cleveland, Ohio.
It reached the highest speed
but col. Kossowski
could not be awarded a prize
because the pilot misunderstood the rules
and made a wrong-side turn at the finishing pylon.
FAILS HAPPEN...
Pirat, make a 180 degree turn
and don't head there!
Traffic pattern is southern.
You Clumsy!
Dear God! Wrong heading! Major fail I made!
Advertising and sport performance
made many coutries
interested in purchase
or license-building the P.11.
In Spain
gen. Franco's army
was interested.
The plane could take part
in Spanish Civil War,
but Poland decided not to support any side of this conflict.
Let's see the plane!
The plane is illustrated
by the PZL P.11c version.
We have a radial engine
in this version placed lower than earlier.
It's durable in combat
but obstructs visibility.
It was air and oil cooled.
Oil cooler was on the right.
There was oil in and out temperature gauge.
Exhaust manifold
is of a ring type, flush with cover.
Ignition was pneumatic
and there was Knock-Out Sava
fire extinguisher system.
Fuel tank housed 320 litres
and could be dropped.
Additional 11 litres of fuel were in the wing.
Plane consumed 150 litres per hour.
Gear was fixed
and Avia shock absorbers were
hidden inside the fuselage.
Large wheels made it
easy to operate on unpaved fields.
Just before the was
and "airfield maneuver" took place -
planes were taken from large airfields
to hidden location takeoff fields.
These had no quality surface
but where unknown to the enemy.
Durable landing gear
with large tyres
was an obvious advantage.
The wing has two struts per side
and is covered with
French Wilbaut type sheet metal.
It has no flaps.
Stalling speed was 110km/h.
The plane was extremely durable.
Never exceed speed was
impossible to reach
(as in the IS-4 Jastrząb glider)
and very tight turns were possible.
Polish pilots fighting in the west
made French fighters
like the Caudron Cyclone disintegrate
because pilots were used
to PZL P.11's aerobatic durability.
Initially two guns were in the fuselage.
The would shoot through the propeller
withnthe JS-2 synchronising system.
It once failed, killing
senior sgt. Walenty Nowak - one of
19 pilots killed in P.11 crashes
before the war outbreak.
Later wing guns were added
but at the cost of agility.
Some pilots wanted no wing guns fitted.
There was ammunition for
36 seconds of fire.
Rear strut could accomodate
Fairchild or K-28 gun camera.
Armament was
first used in 1936 by Witold Urbanowicz.
He shot down a Soviet
Polikarpov R-5 spy plane.
Soviets would fly over Poland
but intercepted usually headed back east.
But in this case the R-5 opened fire
to which Urbanowicz responded
shooting the plane down over moors.
Cockpit was open
Gun trigger was on the column -
initially mechanical,
later hydropneumatic
which allowed for precise control while pulling
the trigger. As you know
back then pilot
had to take aim
steering the whole plane.
Throttle lever in PZL planes
worked the other way round as in British planes
lever forward - minimal power,
lever backwards - open throttle.
So not only durability
was something pilots
had to forget flying foreign planes.
Harness had tensioner.
Pilot could reach down
to pick up
Perkun signal gun charges
12 of these were in the cockpit floor.
On the left there is a hole
used for placing signal gun barrel
to fire the flare outside.
There was a radio -
Polski Philips N2/lm.
Initially the aerial was above the fuselage
and it shadowed the signal.
Late the aerial was
placed in V-shape
between the fin
and aerial masts on wingtips.
It gave 10km plane-plane range
and 50km plane-ground range.
Behind a headrest there was a trunk.
Up to this point the fuselage
was frame-based.
Rear part was semi-monocoque.
Plane was nicknamed
"Puławszczak", "Jedenastka" or "Pezetelka".
149-175 craft were built in Poland,
and Romanian IAR works
license-built 95 planes.
PZL-50 Jastrząb fighter
was developed at the time.
It was cancelled,
but there were 150 Merkury VIII engines already made for it.
There was an idea
to fit P.11's with these engines.
This created a PZL P.11g "Kobuz"
with closed cockpit,
wheel fairings
and the new engine.
One plane was built
and first flew two weeks before the war.
Powerful engine
did not make up for increased weight.
"The Elevens" turned out
much slower than the Bf-109's.
Also some German bombers
were faster.
Poland could not make up for
damaged or shot down fighters.
But P.11 had
significant agility advantage,
good climb range,
and durability for makeshift runways.
On September 1st, 1939
at 7:30 AM
P.11 was shot down by Stuka.
It's pilot - cpt. Mieczysław Medwecki
was the first pilot
killed in WWII action.
His plane crashed or landed
and burned down in the field
between Chrosna and Morawica, near Balice.
Medwecki was 35,
and pilot who shot him down -
Frank Neubert - was 24.
Medwecki's wingman
cpt. Władysław Gnyś
flew west toward Olkusz town,
and shot down a Dornier 17 over Żurada.
Falling down bomber collided with his wingman.
The two Do-17's are the first
allied air victory in WWII.
It is referred to as "allied"
even though the only allies for Poles
were only other Poles at the time.
Gnyś and Neubert
became friends after the war,
they even met - first time in 1989.
Gnyś died in 2000,
Neubert in 2003.
At the time, elsewhere over Poland
lt. Aleksander Gabszewicz and cpl. Andrzej Niewiara
shared a victory
over Heinkel-111
the first plane shot down
over Warsaw.
Gabszewicz was a bit later shot down, but bailed out
to fight till the end of the war (also in Squadron 303).
Niewiara was killed in 1941 in France, flying a Spitfire.
Also in the first day of the war
P.7 and P11 fighters
entered the first WWII large aerial battle.
Over Nieporęt
30 Polish fighters
intercepted an armada
of 80 Luftwaffe bombers and 20 fighters.
Poles shot down
only 6 out of 100 planes,
they made 80 bombers
retreat and fail to bomb Warsaw.
Before Poland falled to Hitler
Polish pilots scored 126 planes destroyed,
10 probably destroyed
and 14 damaged.
Most of this score was
by the P-series fighter pilots.
One P.11 was evacuated to Lithuania,
one accidentally landed
in the USSR territory,
and one flew to Hungary.
In the back of the fuselage
col. Mateusz Iżycki was hidden.
He later bacame
Chief Inspector
of Polish Air Force in the west.
2 people fled in a single-seater.
Planes taken over by the Germans
were used for propaganda movie.
Planes taken over by the Soviets were destroyed.
The remaining ones flew to Romania,
where they were illegally taken over by the army.
They flew as fighters until 1942
and until 1945 as trainers.
After the war they were scrapped.
One German-stolen craft
was in Goering's collection in Berlin.
After the war Poland reclaimed it
in late 1980's it was restored in PZL works,
and now it is in Aviation Museum in Kraków,
where I encourage you to see it
as the only remaining
plane in the World, that fought with the Luftwaffe since the very first day of the war.
This PZL P.11c.
We can see P.11 replica
in Dęblin Air Force School.
and there is a foundation
building an airworthy replica.
We long to see it in mid air.
There was also a 66% scale replica
sold in 1980s/1990s in the US
as a kit to build.
This was also an airworthy plane.
I saw few pictures,
if someone knows anything more about it
let me know.
Does this replica still exist?
I know that P.11
inspires many people,
there are beautiful models built,
if you know any stories,
or places where P.11
were shot down
please also let me know.
Thank's for watching,
take a look at PZL P.11c technical data,
and see you in the next episode. Bye!
