With
the sudden flurry of airship production in the late part of the
war, it was obvious that when the war finished decisions regarding
the use of airships and their roles were to be made. The R36 was
one of the last batch of ships completed in the early 1920s which
was forced to change with the situations around it. This did prove,
however, that the ship could be certainly classed as multi role.
Designed
and built by Beardmore in Scotland, the R36 truly belonged to
the lengthened "R 33" Class of the R 33 and R 34. Her
original designs were produced by the new Airship Design Department
and design work commenced in November of 1917. As with the R 33,
fate was dealt to the Allies when the L 48 was forced to land
at Courbonne-les-Bains in October of 1917, therefore handing over
Zeppelin design secrets to the Allies. The R36 and R37 were designed
to be a stretched version of the L48, attaining more lift by adding
another bay of some 33 feet and giving her a total length of 672
feet. Her diameter was the same as the standard '33 class ship
of 78ft 9in.
With
the role of airships changing from a military scouting role to
more of a civilian role, it was agreed that the design concept
of the R36 was to be altered during her initial construction phase.
Although construction started during the war, the ship was not
finished until well after, and with hostilities ceased, the civil
role of the ship was agreed. The main changes were that the command
gondola, which had been designed as separated from the main hull,
was mounted flush with the hull as with the R31 and R32. A civilian
role for the ship was decided and the R36 was to be able to carry
a passenger complement of some 50 passengers who would be able
to be granted the latest comforts and be able to sleep on board
the ship in Pullman type accommodation. The only contemporary
ships at the time which had been designed to even satisfy the
requirements for passenger accommodation, were the LZ120 "Bodensee"
and LZ121 "Nordstern", which when completed in 1921
could only carry up to 20 passengers. The project to convert the
R36 was at the very least ambitious
To
fulfill the requirement for the passenger-carrying role, the R36
passenger car was designed to be attached to the hull behind the
control car. The passenger accommodation straddled the centre
of gravity within the ship, and therefore was able to have people
walk about within it, without affecting the trim of the ship.
Entry to the passenger accommodation was via the nose of the ship,
as bow mooring gear had added to the ship during construction.
The passengers would walk down a covered triangular gangway along
the keel and then to a staircase which would lead them down to
the passenger accommodation behind the control car. The car was
131 feet long, 7 feet 6 inches in height from floor to ceiling
and 8 feet 6 inches wide at floor level. The sides of the car
sloped upwards to adjoin the side of the airship hull and fairings
at both ends were designed to reduce air resistance.
Inside
the car were 25 double cabins arranged along the sides. These
cabins were arranged during the day with two wicker chairs and
a folding table. At night, two bunks were released on hinges and
let down to provide the sleeping accommodation, with curtains
screening off the cabins at night. It was noted that the wicker
chairs, carpet and general finishing of the cabin were made of
lush blue damask. A galley was provided for the provision of hot
food to the passengers, along with two sets of lavatories and
wash rooms. The "ladies" was placed forward whilst the
"gents" was placed next to the galley amidships. A storeroom
for provisions and luggage space was offered at the aft end of
the car.
The
crew consisted of four officers and 24 men. This also included
A H Savidge who served as Chief Steward, and later went joined
the civil airships, R100 and R101. The crew accommodation was
not within the main passenger car, but up within the hull as with
the normal accommodation on the '33 class ships.
The R36 carried 5 engines, 3 of which were Sunbeam Maori types
and two smaller engines were recycled from the crashed L71 and
added to the front of the ship. This was the same engine configuration
as used on the R101.
The R36 was launched at 3.00pm on 1st April 1921 at the Beardmore
works at Inchinnan near Glasgow. The Captain of the ship was Flight
Lt A. H. Wann, who later went on to a career with the R38. On
her first trial flight, she flew over Glasgow and Renfrew before
returning to the base some 2 hours later. She was secured back
in the shed by 6.45pm.
On
the 2nd April 1921 the R36 made her delivery flight to Pulham.
The idea being that this flight was to give the engines a good
run and allow the ship to "settle"., The crew would
also be able to get the feel of the new ship and design. The ship
left at 7.40pm on the cool evening with a 20 knot wind blowing.
The ship flew down over the Forth Bridge, rounded St Abbs Head,
continued over Berwick, then turned south towards Pulham. Arriving
at 8.00am the next morning, April 4th, the R36 was to remain in
flight over the airfield for crew tests then be eased down and
finally moored at 12.15pm to the mast. The journey time of 15
hours and 35 minutes covered some 412 miles.
On the next day, April 5th 1921, the R36 had been ordered to make
a demonstration flight with representatives from the Air Ministry
on board. The R36 left Pulham at 07.25am bound for the outskirts
of London. Conditions became turbulent when the R36 was crossing
Chorley Wood and remained so. Continuing down to near Salisbury
Plain, the ship rose up to 6,000 feet when she began manoeuvres.
In the turbulent air, the R36 began to start a fast turn of 130
degrees with the engine revs increased. During this turn a windsheer
in the turbulent air, put severe pressure on the rudder and hence
caused the top rudder and starboard elevator to crumple. This
caused the ship to fall rapidly for about 3,000 feet whereby the
ship had attained a severe nose down angle, but this was arrested
and the ship was managed under control and re-trimmed using both
crew and water ballast. The R36 climbed back up to 4,500 feet
and immediate repairs were made to the damaged control surfaces
at the rear of the ship. The demonstration flight was aborted
and the ship limped home on her one remaining rudder and elevator,
altering the engine speeds to give a degree of directional control.
The ship finally made it back to Pulham at 9.15pm, however there
was no room to house the ship as the Pulham shed contained the
R33 and the two German Zeppelins, L64 and L71. The R33 was quickly
taken out of the shed and moored to the mast, and the R36 moved
in to the shed next to the two German ships.
Repairs
were carried out on the ship to repair and strengthen her rudders
and elevators. The R36 came out on the evening of 8th June for
a test flight. Even though she had been fully loaded for a long
flight, it was decided that the ship would only undertake a local
flight for 2 hours 15 minutes and then return and be secured at
8.15pm.
The next morning, 9th June at 9.26am, the R36 undertook an extensive
flight of 11 hours, flying cross-country towards Nottingham, then
up towards Manchester and Liverpool, then returning to Pulham.
She secured her moorings at 8.30 in the evening after a flight
of 11 hours.
The
role of the R36 was now coming under scrutiny and it was deemed
that the trial flights were to continue and ideas emerged that
the ship should start to take a role within the Empire communications
plan. It was proposed that the ship should try a circular route
around the Mediterranean and a non stop flight to the Middle East.
These ideas were not so far fetched, as contemporary sources believed
the ship had the range and the speed to achieve this. Whether
in practice she could have carried out such demonstration flights,
we would never know.

On 10th June the R36 was loaded up again for another longer test
flight. At 10.00pm in the evening, the ship slipped the mast,
and made her way southwest towards London. At 1.00am the next
day, she altered course for Southampton and by 4.00am the ship
was passing over Portsmouth towards the Solent. An impressive
speed as today the same journey by rail takes nearly five hours.
The ship climbed to 3,500 feet, headed out over the Solent and
set a course towards the Channel Islands. The passengers could
see France some 21 miles away and would have had a spectacular
view over the ocean in wonderful accommodation. Sark was seen
just two miles away to the starboard. Passing over St Helier,
the ship turned and headed back to the base, travelling towards
Lizard, in Cornwall. Crossing Cornwall and Devon, the ship took
advantage of a following wind and flew up towards Swindon, Oxford
and Aylesbury. Crossing the Home Counties of Buckingham, Hertfordshire
and Cambridgeshire, then heading towards Suffolk, the ship came
in sight of Pulham at 1.05am. At 4.00am on 12th June the R36 was
secured to the mast. The R36 completed an epic voyage with considerable
ease over mixed conditions of land and sea, for 29 hours and 54
minutes, of which 446 miles was over land and 288 miles over sea,
a total of 734 miles.
The
R36's high profile passenger accommodation allowing her to fulfill
a number of different roles gave cause for a number of requests
for the use of the ship. The Metropolitan Police requested that
the ship be used for aiding in communicating information about
traffic congestion around the Ascot Races. The original "eye
in the sky" would be used to signal to the local Police Force
the areas of congestion from above the races.
Only 2 days after the epic long distance test, the R36 was slipped
from her mast at 7.31am on 14th June with a passenger compliment
of both representatives of the police force and journalists on
board for the flight. The ship flew southwest towards Wembley
and Ealing making 60mph, and then turning towards Windsor Great
Park. At 9.45am the R36 was in position and was watching the roads
of Staines and Windsor, reporting to the police on the ground.
A summer lunch of hams and salad with beer, fruit salad followed
by cheese and biscuits was served by Steward A H Savidge as the
ship cruised over the countryside surrounding the racecourse.
At 2.00pm the ship overflew the Croydon airfield as the journalists
dropped their reports by parachute to be sent by motorcycle courier
to newspaper offices in Fleet Street, London.
As
with great British traditions, afternoon tea was served at 4.00pm
and it was noted that the food and beverages on offer were comparable
to the grand scale of lunch. The ship returned to her traffic
reporting duty in the late afternoon as the traffic built up after
the race meeting. She then turned for home, crossing North Hertfordshire
and Knebworth house en route to Pulham. The R36 was moored at
10.00pm that day. A round aerial cruise of some 556 miles for
14 and a half hours, carrying 60 passengers and crew.The gruelling
trials continued and the next day the ship was readied on 17th
June for another demonstration flight, this time for Members of
Parliament; a simple summer afternoon flight of 3 hours around
the Norfolk and Suffolk countryside.
On
21st June the ship slipped her mast at 8.00am for another trial
flight. Flying north from the airship station, she continued up
the coast as far as Scarborough in Yorkshire. There she turned
inland and headed for York and returned via Howden and south to
Cramwell, which she reached at 5.45pm. Turning and heading in
an easterly direction, she headed home towards Norwich. When coming
in to land at Pulham, Commander Scott took over from Lt Irwin
and decided to direct the landing himself. The mooring rope was
dropped at 9.15pm and secured to the mast. However the ship approached
the mast far too quickly and the rope fouled the bottom of the
mast and brought the ship up with such a jerk that two of the
forward emergency ballast bags released their contents. The bows
pitched up sharply and the full length of her cable halted the
ship. The strain caused the bows to collapse at frame 1. The ship
was eased down and put in the hands of the handling party. By
10.00pm it was decided that the ship be accommodated in a shed
immediately. However the only vacant space was back at Howden
as all the berths at Pulham were full and the mast was not capable
of accommodating a ship.
The
wind began to pick up and it was then decided that urgent action
be taken. The sacrifice of the L64 ensued as, unable to get the
ship out of the shed, it was decided that the L64 be lowered to
the shed floor, and everyone on the base, be set about to dismantle
the ship with hacks and saws. By 2.00am on the 22nd June there
was enough space cleared to accommodate the R36 and the ship eased
in to the shed. This was always a tricky manoeuvre and, as found
with the German Zeppelins, an airship is at its most vulnerable
when being brought in to or out of the hanger. Whilst being moved
in to the shed, a gust of wind caused the side of the ship to
slam against the shed doors and caused damage to her port side
amidships.
The ship was finally secured at 7.00am on 22nd June. It was noted
that Lt Irwin broke down when he saw how much damaged had been
done to the ship. The official court of inquiry records that the
blame fell on equipment failure.
With the R36 in her shed and the whole airship scheme under considerable
review, it was decided to leave the ship in the hanger and not
start repairs until such time a decision as to what exactly was
to be done with the British airships. One consideration following
the crash of the R38 was offered by Commander Scott in the setting
up of a private company with the intention of selling the R36
to the Americans as a replacement for the loss of the R38.
Two
years later with the revival of the Airship Scheme in 1924, the
provision of the refurbishment of the R33 and R36 was incorporated
into the idea that the ship be used for testing the routes on
the Imperial Airship Scheme. A grant of £13,800 (£483,500
today) was given to have the ship refurbished. A replacement outer
cover was added to the ship, the idea being that the R36 would
carry out a non-stop flight to Ismailia in Egypt to gather meteorological
and other data on the trip. Work was finished in August 1925 and
the ship was due to fly in October of that year. It was recalculated
that the ship would not have enough disposable lift for the journey,
having a lift of some 16.5 tons for fuel and passengers. It was
therefore decreed that the flight be cancelled. As the airship
scheme continued to gather momentum with the design concepts for
the larger 5,000,000 cft ships, the R36, designed some 8 years
earlier, would not fit the current requirements. The R36 remained
in the hanger until June of 1926 when it was decided that the
ship be scrapped and she was dismantled.
It is of interest to note that there is a set of plans for the
R101 in the Public Record office, showing a concept drawing of
the ship with the exact same engine configuration and a totally
external passenger car, similar in design shape and style to that
of the R36. This of course later evolved in to the R101 design
as well known today.
Even though the R36 was initially built to be a military airship,
her conversion in to a civil role proved that she could carry
out the flights and provide comfort and luxury which was later
continued in the larger ships. She was a groundbreaking airship
which in 1921 had a passenger complement larger than contemporary
airships and larger than that of even the Los Angeles and Graf
Zeppelin. She would only be surpassed by the later ships R100
and R101 in passenger comfort. Her unique lines and layout gave
her a sleek style all her own, not copied or surpassed by any
other airship ever built.
