More of Roy Evans’s Dunsfold Aerodrome reminiscences.
In late December 1962 we had a heavy fall of snow over the south of
England and many of the local roads were in a terrible state as very
few had been treated or ploughed. On the second day a Council lorry
managed to get through the road into work from Dunsfold village, and
workers in the back threw shovel loads of sand and salt across the
surface. That night there was a hard frost and for over a month the
surface resembled a ploughed field of solid cross ridges.
On the airfield there was, initially, only one snow plough
available, a large blade fitted on the front of a fuel bowser. By the
end of the third day three more bowsers and the two six wheel AECs had
large blades, and the two smaller Bedfords had smaller slush blades
with a rubber lower edge.
The really heavy snow was tackled by the AECs
although they couldn’t cope with ice; it was a case of waiting for a
thaw and this proved to be a big problem. The only other bit of snow
clearing kit was the ground staff’s Nuffield tractor which, fitted with
a front loader bucket, was ideal for clearing up packed snow left on
corners by the ploughs; a very time-consuming task and very cold too as
there was no cab. Outside factory working hours all the vehicles were
at the Fire Service’s disposal as there was nobody else on the
airfield!
Although the Company wanted a clear runway and access roads it was not prepared to fund the personnel so the job was on our shoulders. Whatever action we took the chances were that the ‘armchair experts’ threw in their criticisms the following morning or after the weekend.
It was decided that following a period of snow the
duty watch would decide if it was serious enough to require clearing.
Once the decision was made the first priority was the main access
roads into the airfield, then the internal access roads to the car
parks to ensure that the workers could at least get in to work. Next
access would be cut between the hangars and the taxiway and then on to
each end of the runway. The runway was left awaiting a decision from
Air Traffic Control and the Pilots’ Office. This was a mammoth task for
our limited resources.
Only two men were allowed out on the ploughs at any
one time as we had to maintain some fire cover always. When the two men
working got too cold (there was no cab heating in the bowsers) they
would return to the Station to be relieved by another two. During
factory working hours at least one bowser driver and one Transport
driver were delegated to man the bowsers and Ground Staff manned the
tractor. During the period which lasted many, many weeks, there were
more snow falls and freezing conditions.
It was at this time that the first P.1127, XP831,
took off from a specially cleared section at the west end of the
airfield and flew to HMS Ark Royal off Dorset for the first ever jet
V/STOL carrier trials whilst most of southern England was covered in
snow.
After that terrible period with snow it was decided
that the airfield needed a boost to its snow clearing equipment. The
Company would not pay for a dedicated snow plough but agreed to an
in-house build (cheaper!) A vehicle was constructed using a small coach
chassis minus its engine. Motive power was provided by a small diesel
engine which was geared to drive the machine at about 10 mph.
On the chassis was mounted an ex-Hunter Avon jet engine facing
backwards and angled upwards at about 15 degrees taking the intake to
about eight feet above the ground. The engine and intake were enclosed
in a steel cage (dubbed the ‘lion cage’) and a full width cab with
soundproofing, was fitted. A large tank for jet fuel was located
immediately behind the cab above the engine.
The jet exhaust was directed forward into steel ducting under the
cab emerging as a ‘T’ shape close to the ground. At each end of the ‘T’
was on oval port roughly twelve inches by six, facing sideways, and
across the width of the ‘T’ was a series of slots facing downwards. The
hot exhaust gasses were therefore directed downwards and sideways in
front of the slowly moving vehicle.
There were several months to wait before we had
sufficient snow in which to test our blower but eventually it came. It
always seemed to snow worse in the night when there was no other help.
On this occasion the snow started on a Saturday night and by Monday
morning many of the internal roads and the runway had frozen snow on
them which is much more difficult to clear. By mid-morning the snow
blower was finally driven onto the runway crewed by staff from the
Production Hangar, the trip taking over thirty minutes, the Avon was
fired up and it started to work.
Chief Test Pilot Bill Bedford came into the Fire
Station and asked to be taken out to observe proceedings. I was
detailed to drive him in our short wheelbase Land Rover so I drove to
just past the engine running pens and stopped on the taxiway about 200
yards abeam of the blower operating on the runway. The CTP wanted to
get closer so I drove onto the grass within 100 yards but he wanted to
get closer still and he opened his side window, looking out. He then
started giving me hand signals because of the noise and I approached
the blower from the rear quarter. Eventually our vehicle was keeping
pace parallel with the blower about 30 feet distant; too close, I
thought. I held back just behind the snow and mist blast that was
shooting across in front of us. The CTP suddenly shut his window and
shouted “Forward!”. I said “What?” so he repeated “Forward!” and waved
his hand. I hesitated but he repeated the order and hand signal so I
gripped the steering wheel tightly and floored the accelerator.
Almost immediately there was a massive thump on the
nearside and several small bangs. I felt sudden pressure on my left
side and arm and then we emerged from the cloud of snow and steam into
brilliant sunshine with Bill sitting against me. He quickly moved back
to his seat beside the window; his face was white and I guess mine was
too. I drove back to the taxiway rather hastily then stopped. We both
got out and inspected the vehicle’s side; we’d gained a few dents
caused by chunks of ice but luckily the nearside window was still
intact. I tentatively asked Bill if he’d seen enough and emphasised
that there was no need to repeat the sortie! The following day he put
out a memo that the snow blower jet engine must not be started until
the vehicle was on the main runway and all aircraft and vehicles must
be kept well clear of this “infernal machine”.
Editor’s Note - The Avon’s snow blower ducting was
designed by Trevor Jordan of the Project Office. The machine itself is
on display at the Brooklands Museum.
