The Early Development Of Hovercraft

Breaking News Posted on Wed, May 27, 2015 21:07:49

Early efforts to Develop Hovercraft

There
have been many attempts to understand the principles of high air pressure below
hulls and wings. To a great extent, the majority of these can be termed
“ground effect” or “water effect” vehicles rather than
hovercraft. The principal difference is that a hovercraft can lift itself while
still, whereas the majority of other designs require forward motion to create
lift. These active-motion “surface effect vehicles” are known in
specific cases as ekranoplan and hydrofoils.

The first
mention in the historical record of the concepts behind surface-effect vehicles
that used the term hovering was by Swedish scientist Emanuel Swedenborg in
1716.

The
shipbuilder Sir John Isaac Thornycroft patented an early design for an air
cushion ship / hovercraft in the 1870s, but suitable, powerful, engines were
not available until the 20th century.

In 1915,
the Austrian Dagobert Müller (1880–1956) built the world’s first “water
effect” vehicle. Shaped like a section of a large aerofoil (this creates a
low pressure area above the wing much like an aircraft), the craft was
propelled by four aero engines driving two submerged marine propellers, with a
fifth engine that blew air under the front of the craft to increase the air
pressure under it. Only when in motion could the craft trap air under the
front, increasing lift. The vessel also required a depth of water to operate
and could not transition to land or other surfaces. Designed as a fast torpedo
boat, the Versuchsgleitboot had a top speed over 32 knots (59 km/h). It was thoroughly tested
and even armed with torpedoes and machine guns for operation in the Adriatic.
It never saw actual combat, however, and as the war progressed it was
eventually scrapped due to the lack of interest and perceived need, and its
engines returned to the Air Force.

The
theoretical grounds for motion over an air layer were constructed by Konstantin
Eduardovich Tsiolkovskii in 1926 and 1927.

In 1929,
Andrew Kucher of Ford began experimenting with the “Levapad” concept,
metal disks with pressurized air blown through a hole in the center. Levapads
do not offer stability on their own. Several must be used together to support a
load above them. Lacking a skirt, the pads had to remain very close to the
running surface. He initially imagined these being used in place of casters and
wheels in factories and warehouses, where the concrete floors offered the
smoothness required for operation. By the 1950s, Ford showed a number of toy
models of cars using the system, but mainly proposed its use as a replacement
for wheels on trains, with the Levapads running close to the surface of
existing rails.

In 1931,
Finnish aero engineer Toivo J. Kaario began designing a developed version of a
vessel using an air cushion and built a prototype Pintaliitäjä (Surface Soarer), in 1937. Kaario’s design included the modern
features of a lift engine blowing air into a flexible envelope for lift. Kaario
never received funding to build his design, however.[citation
needed
] Kaario’s efforts were followed closely in the Soviet
Union by Vladimir Levkov, who returned to the solid-sided design of the Versuchsgleitboot. Levkov designed and built a number of similar craft during the 1930s,
and his L-5 fast-attack boat reached 70 knots (130 km/h) in testing.
However, the start of World War II put an end to Levkov’s development work.

During
World War II, an engineer in the United States of America, Charles Fletcher,
invented a walled air cushion vehicle, the Glidemobile. Because the
project was classified by the U.S. government, Fletcher could not file a
patent.

Christopher Cockerell

The idea
of the modern hovercraft is most often associated with a British mechanical
engineer Sir Christopher Cockerell. Cockerell’s group was the first to develop
the use of an annular ring of air for maintaining the cushion, the first to
develop a successful skirt, and the first to demonstrate a practical vehicle in
continued use.

Cockerell
came across the key concept in his design when studying the ring of airflow
when high-pressure air was blown into the annular area between two concentric
tin cans, one coffee and the other from cat food. This produced a ring of
airflow, as expected, but he noticed an unexpected benefit as well; the sheet
of fast moving air presented a sort of physical barrier to the air on either
side of it. This effect, which he called the “momentum curtain”,
could be used to trap high-pressure air in the area inside the curtain,
producing a high-pressure plenum that earlier examples had to build up with considerably
more airflow. In theory, only a small amount of active airflow would be needed
to create lift and much less than a design that relied only on the momentum of
the air to provide lift, like a helicopter. In terms of power, a hovercraft
would only need between one quarter to one half of the power required by a
helicopter.

Cockerell
built several models of his hovercraft design in the early 1950s, featuring an
engine mounted to blow from the front of the craft into a space below it,
combining both lift and propulsion. He demonstrated the model flying over many
Whitehall carpets in front of various government experts and ministers, and the
design was subsequently put on the secret list. In spite of tireless efforts to
arrange funding, no branch of the military was interested, as he later joked,
“the navy said it was a plane not a boat; the air force said it was a boat
not a plane; and the army was ‘plain not interested.’

SR.N1

SR.N1
general arrangement

This lack
of military interest meant that there was no reason to keep the concept secret,
and it was declassified. Cockerell was finally able to convince the National Research Development Corporation to fund
development of a full-scale model. In 1958, the NRDC placed a contract with Saunders-Roe
for the development of what would become the SR.N1, short for
“Saunders-Roe, Nautical 1”.

The SR.N1
was powered by a 450 hp Alvis Leonides engine powering a vertical fan
in the middle of the craft. In addition to providing the lift air, a portion of
the airflow was bled off into two channels on either side of the craft, which
could be directed to provide thrust. In normal operation this extra airflow was
directed rearward for forward thrust, and blew over two large vertical rudders
that provided directional control. For low-speed manoeuvrability, the extra
thrust could be directed fore or aft, differentially for rotation.

The SR.N1
made its first hover on 11 June 1959, and made its famed successful crossing of
the English Channel on 25 July 1959. In December 1959, the Duke of Edinburgh
visited Saunders-Roe at East Cowes and persuaded the chief test-pilot,
Commander Peter Lamb, to allow him to take over the SR.N1’s controls. He flew
the SR.N1 so fast that he was asked to slow down a little. On examination of
the craft afterwards, it was found that she had been dished in the bow due to
excessive speed, damage that was never allowed to be repaired, and was from
then on affectionately referred to as the ‘Royal Dent’.

Skirts and other improvements

Testing
quickly demonstrated that the idea of using a single engine to provide air for
both the lift curtain and forward flight required too many trade-offs. A Blackburn
Marboré for forward thrust and two large vertical rudders for directional
control were added, producing the SR.N1 Mk II. A further upgrade with the Armstrong
Siddeley Viper produced the Mk III. Further modifications, especially the
addition of pointed nose and stern areas, produced the Mk IV.

Although
the SR.N1 was successful as a testbed, the design hovered too close to the
surface to be practical; at 9 inches (23 cm)[citation needed]
even small waves would hit the bow. The solution was offered by Cecil
Latimer-Needham, following a suggestion made by his business partner Arthur
Ord-Hume. In 1958, he suggested the use of two rings of rubber to produce a
double-walled extension of the vents in the lower fuselage. When air was blown
into the space between the sheets it exited the bottom of the skirt in the same
way it formerly exited the bottom of the fuselage, re-creating the same
momentum curtain, but this time at some distance from the bottom of the craft.

Latimer-Needham
and Cockerell devised a 4 feet (1.2 m) high skirt design, which was fitted
to the SR.N1 to produce the Mk V, displaying hugely improved performance, with
the ability to climb over obstacles almost as high as the skirt.[citation
needed
] In October 1961, Latimer-Needham sold his skirt patents
to Westland, who had recently taken over Saunders Roe’s interest in the
hovercraft. Experiments with the skirt design demonstrated a problem; it was
originally expected that pressure applied to the outside of the skirt would
bend it inward, and the now-displaced airflow would cause it to pop back out.
What actually happened is that the slight narrowing of the distance between the
walls resulted in less airflow, which in turn led to more air loss under that
section of the skirt. The fuselage above this area would drop due to the loss
of lift at that point, and this led to further pressure on the skirt.

After
considerable experimentation, Denys Bliss at Hovercraft Development Ltd. found
the solution to this problem. Instead of using two separate rubber sheets to
form the skirt, a single sheet of rubber was bent into a U shape to provide
both sides, with slots cut into the bottom of the U forming the annular vent.
When deforming pressure was applied to the outside of this design, air pressure
in the rest of the skirt forced the inner wall to move in as well, keeping the
channel open. Although there was some deformation of the curtain, the airflow
within the skirt was maintained and through natural factors such as escape of
air and balance of pressure within the skirt.

Amateur Racing Series

Breaking News Posted on Mon, May 21, 2012 13:07:28

The weekend was predicted to be cold, damp and in general misserable but an invite from our friends at the Amateur Hovercraft Racing Event meant that the fun had arrived and the weekend was something to look forward to.

We were made very welcome upon arrival and a Hot Dog and a Hot Cup Of Tea was a real welcome of what was to come. These guys are simply so exciting to watch and offer thrills a plenty and if they come to a location near you, I would urge you to go and watch.

Here is a typical start for these super quick guys and I hope you enjoy in some way what we enjoyed all day. http://youtu.be/aNh1LexA8Ig smiley



Drought in UK

Breaking News Posted on Fri, April 27, 2012 10:41:03


If we are to belive the weather office in the UK we must accept their findings that the UK is in sever drought. In God’s own county of Yorkshire, we have had three weeks of drought by day and drought by night, so much drought that the rivers are all in flood and the reservoirs are all overflowing which is a pretty sight to see but after three weeks of drought falling from the skies, I’m fed up of drought. smiley

For all of our friends and families in the South of England it’s a totally different story. They are suffering a hose pipe ban and a sever lack of water to which one wonders why we in the north can’t help in some way. We have buckets of drought to spare but with no practicle solution to sending it to you. The weekend outlook is for up to 2 inches of rain…. “er” drought to fall in my area with even more for the South. I suppose the weather experts will then tell us it’s all fallen in the wrong places !!!. smiley

On the possitive side, it’s great weather for a Hoverpod as the craft will travel across just about any surface whether it is water or land and as such the severe climate changes around the globe is something that F1 Hoverpod have taken on board as part of it’s development process for the future. A small light vehicle to which has the ability to travel at high speed across water, ice, snow or land was many advantages over conventional products to which have their own natural restrictions. The UK may be in drought but F1 Hoverpod is leading the way in technology for the future climate changes and potential disasters facing the world.

Latest News from F1 Hoverpod Ltd

The exciting news from the home front about F1 Hoverpod Ltd is in many ways a
continuation of developments surrounding the business and team continues going
from strength to strength in a very positive and efficient way, all of this on
the back of what was at huge victory in the early part of 2012 regarding the
very damming comments posted on the internet of which in the end the truth
finally came out. Whilst the truth was all that was sought from the team, the
deleting of such content was something that all of the big three major search
engines were so sympathetic to our plight and were so professional in the way
they dealt with the problem and were so very kind in assisting in the removal of
the now proven to be libel comments from the internet under the instruction and
guidance of the independent body “Chilling
Effects
”. The panel of which are a body of professional experts chosen from
the legal world as well as academia and who combine there efforts to assess the
content and all of the trace elements of where, why and who posted such
information and confer to conclude and base the final outcome/decision upon the
reality and not the gossip. The outcome was a total victory for F1 Hoverpod who was totally exonerated
of any wrong doing and now the Lawyers take up the task of damages action which
now starts in regards to the party or parties whom posted such content. smiley

It’s now late March and has seen plenty of good progress
within the team of F1 Hoverpod Ltd
and with the corporate structure and board changes amongst some of the
developments from within the group of
companies, it’s been a very welcome and pleasant surprise that arrived in early
March with an invite from a very prestigious Institution requesting that the
team present a lecture to the academics regarding the pathway and developments
of F1 Hoverpod and its partner
company F1 Hoverpod Racing of which
has attracted so much media and personal interest from around the globe, in
most recent times of which the gossip columns have now confirmed has come from
the Middle East and Asia. What I am allowed to confirm today is that the
progress and discussions are an ongoing situation and all in a positive manor,
so for the short term I can say the signs are truly encouraging at this early
stage.

As many of you who are fans of social networking now know by
following us on Facebook, there has been a well documented tour of Europe
organised by some of the key members of the team with the intention of drawing
attention to the business and to encourage the interest from within those
countries to show some support for the business and bring the subject of
Hoverpod Racing into the arena and once again the news from the front line is
that this trip was a huge success, a planned further trip to Switzerland and
Central Europe is potentially in the offering and I will confirm this as and
when the timing has been confirmed.

F1
Hoverpod
and F1

F1 Hoverpod Ltd

Breaking News Posted on Tue, March 20, 2012 10:28:23

F1 Hoverpod® Ltd

It’s been rather a wonderful year so far, it all started
with the good news of the victory over the alleged comments now proven to be
unfounded and unsupported allegations (lies) posted by a vicious and malicious
person to which the authorities are now pursuing and I assume at the end an
compensation claim may be in the offering. The very best thing that came out of
the whole five (5) year exercise was the good working relationship to which was
formed by F1 Hoverpod Ltd and the big
three search engines and at this point I wish to extend our very best wishes to
them all and a huge thank you for the kind and sensitive way in which the whole
matter was handled.

February brought out yet more support from some huge names
from the world of Motor Sport and from the Institutions to which we have worked
with in the past, it’s a nice feeling to rise up and stand back on the success
stand where our pride and respect has been fully restored. The success has gone
as far as to an invite to speak at a very well respected audience in regards to
the progress of F1 Hoverpod and the highs and lows along the way.

The reinstating of good standing and trust
shown by many of our partners has not gone unnoticed and I along with the whole
team are eternally grateful for the support shown.

March has brought many business meetings and interested
parties to the table from the close nit community within the Investment Banking
world who only ever look at the business and the figures and never ever to
gossip and from potential working partners from a whole variety of locations
throughout the world. I often think that the measure of success can only ever
be judged by the strength of character of the key people involved and to that
end the whole team deserves a huge pat on the back. If you are keen to follow
the progress, I recommend you check out the Facebook
site and join in with the action. For all the interested parties who are
supporting the F1 Hoverpod Racing
business and wish to join the action as it happens, please feel free to join
the F1 Hoverpod Racing’s own Facebook site “HERE

Start of New Year

Well, it’s all go here at team HQ and for the staff and team members there is
some Breaking News to which is placed on top of everything else of which is
happening and all of which are gaining pace and momentum.

The important announcement for today is in reference to the
alleged Posting of Material considered to be of a libel nature on a web site
known as Rip off Report and the
identity of the posting was assumed to be protected. Not so and the Reaction of
which was that after a major investigation by Bing, Yahoo and Google combined
with a forensic team of internet science experts, the content of said posting
was considered and proven to be wholly untrue and without foundation. Whilst I’m
not at liberty to say who posted the slander and libel comments to the web site
Ripoff Report, what I can say is the
International Reaction to such comments will be felt throughout the Hovercraft
fraternity to which has an extremely loyal fan base.

The Conclusion by all three (3) of the major search engine
internet operators was to comply with the law as set out in the countries affected
by said comments and I am pleased to say that those very damming comments have
been removed in full. The action and investigation has taken some 5 years in
total to conclude and whilst the team at F1
Hoverpod Ltd
and it’s associate F1
Hoverpod Racing
Ltd have had to burden the assumed guilty by so many, the perpetrator
has simply hidden behind a IP address to which they assumed was safe. “Not So”
I’m glad to confirm.

Now that F1 Hoverpod
has managed to confirm a 100% clear conscience and maintain its dignity, its
business as usual and back to the plan and brining the world a brand new Motor
Sport where the whole family can join in and enjoy.
