Since you liked that one.....
The response to
the "Nautilus" story was such that the history teacher in me said, "Why not go farther back?"
So here goes. This is gonna take several blog entries. There's no really good
way to break these up, but I'll try by doing non-military attempts pre late
1800s first.
For longer than
we have real records, there have been attempts to explore underwater. The
earliest example we find is anecdotal, and alleges that Alexander the Great actually
had himself lowered underwater in some sort of glass diving bell.
It
is worthy of note that this painting, of Islamic origin from the 16th century, is unique in several
ways. First, it portrays Alexander dressed in 16th century Islamic attire,
though he had been dead for about a millennium before Islam was established. Second, this painting shows images of human
beings, not traditionally done in the vast majority of Islamic cultures, especially
in that time period. That fact tends to indicate that the painting is Persian
or Turkish, not traditional Arabian. It
is worthy of note that there was no semblance of propulsion involved here,
other than the boat above.
The Bourne design
(not a movie title)
The first really documented attempt to
design a craft actually capable of submerging and resurfacing was probably the
brainchild of Englishman William Bourne, circa 1578. Although there were discussions
and various "plans" for submersibles or submarines during the Middle
Ages, Bourne actually designed the first prototype submarine in 1578. This
was to be a completely enclosed boat that could be submerged and rowed beneath
the surface.
Bourne's concept design
It had a conventional hull, similar to a modern Britsh canal
barge, which could be sealed, as could the oarlocks (yep, oarlocks!) and there
were leather bellows (for want of a better term) which could be expanded or
contracted by screws to increase the volume of the vessel (making it float) or
decrease it, allowing submergence. It
bears mentioning that the device was never built, but one assumes Bourne had
every confidence that it was feasible, although he may well have been the only
one who thought so. It is also significant that Bourne was the first to analytically
discuss buoyancy and displacement with respect to a submersible craft.
Archimedes would have been proud, and would probably have understood.
Drebbel's "leather
clad" Submersible
Cornelius Drebbel
There are anecdotal
references to a couple of failed attempts, but no plans or even artist's
concept drawings until Cornelius
Jacobszoon Drebbel, a Dutchman in the service of James I of England, designed and built the first successful submarine
in 1620.
Drebbel's 3rd design on the Thames
Drebbel's boat was also propelled by human manual labor (oars in this case) as would they all be until post Civil War and his first design is
thought to have incorporated floats with tubes to allow air down to the rowers.
This actually is kinda/sorta the first "snorkel"(albeit a crude attempt) although ancient
Egyptian drawings do show men underwater breathing through hollow reeds. This
actually makes it something other than a real submarine, but I won't tell. Two of Drebbel's crafts were actually tested in the River Thames between 1620 and
1624.
Reports of the
time suggest that King James I actually rode in the third submarine on a trip
under the Thames in 1626. This final model had 6 oars and could carry 16
passengers. At a dazzling depth of 15 feet submerged, the vessel sank when bladders
which the rowers sat on (surfaced) were
allowed to fill with water via tubes . These would be the first inboard variable ballast
tanks, which also explains the 15 foot depth limit, huh? The submarine stayed submerged for three
hours and could travel from Westminster to Greenwich and back, cruising at a
depth between 12 and 15 feet.
Apparently
Drebbel also experimented with using some chemical combination involving
saltpeter (Potassium nitrate, the oxidizer in gunpowder) to create oxygen inside
the vessel., allowing as long as three hours submerged operation. To surface,
the rowers placed the bladders back under their collective asses and sat on
them, forcing the water back out to sea, and "Hey presto, prepare to surface!"
Model of
Drebbel's first (and smaller) design
Probably the first written arguments for why submarines
might be militarily useful came from a somewhat unlikely source - a member of
the Clergy! The strategic advantages of submarines were first set out by Bishop
John Wilkins of Chester in his book - Mathematical Magick in 1648 :
"1. Tis private: a man may thus go to any coast in the
world invisibly, without discovery or prevented in his journey.
2. Tis safe, from the uncertainty of Tides, and the violence
of Tempests, which do never move the sea above five or six paces deep. (Boy can
I call "bullshit" on that allegation. This guy obviously never was Diving Officer under the Norwegian Sea in January!) From Pirates and Robbers which do so
infest other voyages; from ice and great frost, which do so much endanger the
passages towards the Poles.
3. It may be of great advantages against a Navy of enemies,
who by this may be undermined in the water and blown up.
4. It may be of special use for the relief of any place
besieged by water, to convey unto them invisible supplies; and so likewise for
the surprisal of any place that is accessible by water."
Papin's "Ugly
Bucket"
Denis Papin
Between 1690 and 1692, the French physicist Denis Papin,
designed and built two submarines, although they were neither slim sleek and
racy or maneuverable. The first design (1690) was essentially just a strong and
heavy metallic square box, equipped with an efficient pump that pumped air into
the hull to raise the inner pressure. When the air pressure reached the
required level, holes were opened to let in some water. This first machine was
destroyed by accident. (probably just as well) The second design (1692) had an
oval shape and worked on similar principles. A water pump controlled the
buoyancy of the machine. neither design had any sort of mobility and was really
more a glorified diving bell, and a poor one, at that.
Papin's "submarine"
It is worthy of
mention that, while Papin designed a relatively shitty submarine, he also
devised what he dubbed the "Steam Digester" which today we simply
know as a pressure cooker. The shape of his "submarine," not
surprisingly, closely resembles the design of his pressure cooker!
By the mid 1700s,
more than a dozen patents for
submarines/submersible boats had been granted in England alone . In 1747,
Nathaniel Symons patented and built the first known working example of the use
of a ballast tank for submersion. His design used leather bags that could fill
with water to submerge the craft. A mechanism was used to twist the water out
of the bags and cause the boat to resurface. (note this is rather similar to
Drebbels "ass bag" ballast!) In
1749, the Gentlemen's Magazine reported that a similar design had been proposed
by Giovanni Borelli in 1680. By this point of development, further improvement
in design pretty much stagnated, until new industrial technologies for
propulsion and stability were developed. could be applied.
Finally for this entry, even though it is a later design,
there was no military goal in mind, so we'll go back later to military subs.
For now let's consider the Icteneos and their designer.
Monturiol's Designs
Narcis Monturiol
Spanish designer Narcis Monturiol was somewhat of an anomaly
among his submarine designing peers, in that he apparently had zero military aspirations
for his brainchildren. He had been a controversial writer and publisher and was
involved in the revolution of 1848 to the extent that he self-exiled to France
for about a year, finally returning to Barcelona and devoting his energies to
science.
While vacationing
in Cadaqués he observed the dangerous job of coral harvesters,
actually witnessing the death of a man who drowned while performing this job.
This encouraged Monturiol to focus on submarine
navigation. In 1857, in Barcelona he organized the first commercial society in
Catalonia and Spain dedicated to the exploration of submarine navigation.
In 1858
Monturiol presented his concept in a scientific thesis, titled "The
Ictineo" ("fish-ship") The first dive of his prototype , Ictineo
I, took place in September 1859 in the harbor of Barcelona.
Ictineo I - 1859
As was the standard of the period, the vessel was human
powered, which Monturiol found inadequate, so back to the drawing board he went.
The result 5 years later was Icteneo II.
Launched in October, 1864. Ictineo II made her maiden voyage
under human power on 20 May 1865, submerging to a depth of 30 metres (98 ft). Note
that, by this time, CSS Hunley had killed three crews at depths of less than 1/3 that deep and had
killed herself in the final process!
Dissatisfied,
however, with the limitations of human
propulsion, Monturiol, after much experimentation, invented a chemical
combination that generated both heat and oxygen when mixed. With the heat
generated by this mixture he hoped to drive a small steam engine, which could
also be powered with coal during surface operation.
Icteneo II
Monturiol's
ultimate plan was to create a vessel
custom-built to house his new engine, which would be entirely built of metal
and with the engine housed in its own separate compartment. Due to the state of
his finances, construction of the metal vessel was out of the question.
Instead, he managed to assemble enough funds to fit the engine into the wooden
Ictineo II for preliminary tests and demonstrations.
In October
1867, Two years and several alterations later, Ictineo II made her first surface journey
under steam power, averaging 3.5 kn with a top speed of 4.5 kn . On 14
December, Monturiol submerged the vessel and successfully tested his anaerobic
engine, without attempting to travel anywhere.
To fully grasp
the significance of Monturiol's achievement, consider that no other submarine
employed an anaerobic propulsion system until 1940 when the German Navy tested
a system employing the same principles on the "too late" Type XVII submarines. The problem of
air-independent propulsion was finally resolved with the construction of the
first nuclear powered submarine, the USS Nautilus.
Today, some of the quietest
and most capable submarines in the world are the AIP (Air Independent
Propulsion) designs built by Siemens and Swedish firms for export.
The boat above reflects Monturiol's vision in the form of an Israeli Dolphin Class boat fitted with the Siemen's fuel cell AIP system - fast, stealthy and capable. Sadly, anyone with the bucks can buy one.
So, for now we leave the land of submarines, I'll be back
with military boats later.
