Handmade
wigs sale last for a long
time with proper care. Wash your wig once a month and hang it up to
dry. Do not brush it while it's wet or damp. When your wig dries,
lightly shake it to fluff it up and if desired set it with rollers while
it is still damp. Makeup artists love wigs because hair does so much to
a person's looks.
Measure your customer's head for proper sizing of their custom
made wig or toupee. Transfer the measurements to your wig block. Using
the measurements, nail the ribbons provided to the wig block.
Place, shape and fit a wet cotton lace over the wig block
completing the wig foundation. Note that the lace is available in many
colors and sizes. Sew the foundation by hand or use your machine. Try it
on for size and fit. and make any adjustments if necessary.
Discuss the desired hairstyle, color, length, thickness and
type of curls with your customer to get the best possible results. Use
real hair only when making the wig. Sort any cut or removed hair into a
hackle and pull it into lengths for storage. Clean the hair carefully
before using. Place the hair between two drawing mats making it ready
for use.
Ever since the very first experimental
wigs sale
boats have been built in the nineteen-thirties, longitudinal stability
has been recognised as a very critical design factor. When not designed
properly WIG boats show a potentially dangerous pitch up tendency when
leaving (strong) ground effect. Powerboats sometimes show the same
tendency, when they meet a wave or a wind gust they may suddenly flip
backwards.
The reason for this behaviour is the fact that the working line of the
lift vector of a wing is located relatively far aft at very small ground
clearances and moves foreward when climbing out of ground effect. The
stability problem can be overcome by installing a relatively large
horizontal tail and although a WIG boat cannot be stabilised by c.g.
movement alone, the location of the c.g. is very important for achieving
acceptable longitudinal stability. A more indepth explanation is found
in the theory section.
Some wing planforms are more stable than others, the reversed delta from
Lippisch proved to be very good, therefore it has been very popular
lately (e.g. in the Airfisch series craft). Not only the planform, but
also the wing section is important for stability. Recent research showed
that wing sections with an S-shaped camber line are more stable than
conventional wing sections. Many new designs have such an S-foil.
Perhaps the most significant developments at this moment, aside from the
Hoverwing, are taking place in China and Australia. Australia not only
with the FS-8, but the well established catamaran builder Incat is
developing a very large trimaran ferry with
wigs sale
support. Although this may not be a true WIG boat, since it always
maintains water contact, it could be a first step to widespread market
acceptance.
Chinese companies have been very actively developing WIG boats over the
past decade. At least three different groups are working on their own
WIG boat. Two of them focus on Russian technology with the TY-1 and Swan
that technically resemble the Volga-2. The third group has taken the
Lippisch approach and added PAR to it, resulting in the XTW-4.
In Germany the military potential for WIG boats was recognised and RFB
was contracted by the German military to develop the X-114, requiring it
to fly without ground effect as well as in ground effect. It became
apparent that the conflicting requirements of a WIG boat and an aircraft
lead to a compromise with little advantages and that the true power of
WIG technology lies in staying close to the surface. Therefore the
development was continued with the Airfisch family of WIG boats that
were incapable of sustained flight without groundeffect. Meanwhile Hanno
Fischer had taken over the project from RFB and he pursued Lippisch'
work at his own company called Fischer Flugmechanik. Their two seat
Airfisch 3 was a very successfull design, which has recently been scaled
up to seat 6 passengers. This craft, the FS-8 will soon be series
produced by a Singapore-Australian joint venture called Flightship.
While the Airfisch technology was being made ready for the market,
Fischer was already working on the next generation of WIG boat with
hovercraft technology to assist at take-off. The 2 seat hoverwing
prototype HW-2VT has been successfully demonstrated many times and now
development continues with a 20 seat version.
Although Alexeiev discarded the tandem wing principle after having
tested the SM-1, the concept was later rediscovered by the German Günter
J?rg. After many radio controlled models he succeeded in developing a
stable WIG boat with two wings in a tandem arrangement, the first manned
craft was the J?rg-II. The tandem WIG boat excels in simplicity and low
cost and is the most boat-like of all WIG concepts. These facts may
explain their initial success with boats up to 25 metres in length
built. Unfortunately some technical and business related problems stood
in the way of true commercial success.
The above are the most relevant developments in
wigs sale
history, but there have been many smaller projects around the world,
some of which should be mentioned here. The Kawasaki KAG-3 was a WIG
boat with water propulsion, but the project was abandoned due to
stability problems. In the USA there have not been many projects that
went beyond the drawing board. Especially Lockheed and David W. Taylor
Naval Ship Research and Development Center (DTNSRDC) have conducted a
lot of research work. DTNSRDC especially in the area of PAR. Some years
ago a company called Flarecraft copied the Airfisch-3 and scaled it up.
Due to their lack of expertise the Flarecraft L-325 was a technical
failure, although the attention from the market and the media was
overwhelming.
The most recent large ekranoplan from the former Soviet Union is the 400
ton Lun which was built in 1987 as a missile launcher. It carried six
missiles on top of the hull. At the time when the Soviet Union fell
apart there was a second Lun under construction. It was about 90 percent
finished when the military funding stopped, because of the financial
situation and the end of the cold war. Some ideas were raised for a new
life for the Lun, they ranged from a passenger ekranoplan to a rescue
vessel. The second Lun was eventually renamed to Spasatel,
wigs sale,
the military systems were removed and work started to finish the craft
as a rescue vessel. Unfortunately there were financial problems and the
work had stopped completely by the mid-nineties. Every now and then
plans are presented to finish work on Spasatel, but it will probably
never be finished due to lack of funding.
After the collapse of the Soviet Union, developing or maintaining big
ekranoplans became impossible for the Russians and the design bureaus
started focusing on smaller ekranoplans for non-military use. The CHDB
had already developed the 8 seat Volga-2 in 1985, but other design
bureaus and companies emerged that wanted to exploit the Russian lead in
WIG technology. The most successfull of these is Technologies and
Transport where the Amphistar was developed as a smaller and more modern
derivative of the Volga-2, both are now in production.
The story of Alexeievs western counterpart, Lippisch, also started
around 1960. At that time he was asked to build a very fast boat for Mr.
Collins from Collins Radio Company in the USA. Alexander Lippisch was
already a well known aircraft designer at that time, being called the
father of the delta wing. In the second world war Lippisch designed the
Me163 rocket powered delta wing airplane which was well ahead of its
time. The boat for Collins, the X-112, was at least as revolutionary a
design with its reversed delta wing and T-tail. This design proved to be
stable and efficient in ground effect and although it was succesfully
tested and followed up by the X-113, Collins decided to stop the project
and sold the patents to a German company called Rhein Flugzeugbau (RFB)
which further developed the reversed delta WIG boat.
The 550 ton KM (Russian abbreviation for prototype ship) was baptised in
1966. In the five years before that, a number of manned and unmanned
prototypes were built, ranging up to 8 ton displacement. They were
designated SM followed by a number, where SM is the Russian abbreviation
for self-propelled model. The KM was built in the (at that time) closed
city Gorky,
wigs sale, now called
Nizhny Novgorod. No foreigners were allowed there and only when the KM
was transported to the Caspian Sea for trials it was discovered by
Western intelligence on sattelite photos. At first they did not know
what it was and assumed that it was a seaplane under construction, later
they found out what it was and called it the Caspian Sea Monster. This
name is sometimes also used for ekranoplans in general. To illustrate
the secrecy surrounding this project at that time: it was even forbidden
to use the word ekranoplan in public.
When the KM programme was launched in 1963 it was very ambitious, it was
to be more than 100 times heavier than the SM-2P, which was the
heaviest ekranoplan at that time. Basically the KM was far ahead of its
time and even today many developers of WIG boats do not consider a craft
of this size feasible within the next few decades.
After the experimental craft the Russian ekranoplan program continued
and lead to the most successfull ekranoplan so far, the 125 ton A.90.125
Orlyonok. The Orlyonok incorporated many features that had been tested
separately in earlier designs: it was amphibious, it had a huge
turboprop engine for cruise thrust at the top of the fin and two
turbofans in the nose for air injection. A few Orlyonoks have been in
service with the Russian Navy from 1979 to 1992.
