The
termination of a space walk by a British Astronaut due to him developing
cold hands and losing dexterity, was a graphic illustration of the necessity
for an effective heating system capable of being built into garments and
supplied with energy from a variety of power sources.
The
David Clark Company in Worcester Massachusetts, having heard of the development
of Gorix E-CT, contacted the Gorix R&D unit in Southport UK to ascertain
if Gorix could be the answer that they were looking for in their search
for a glove heating element. At the time of the initial enquiry, Gorix
Ltd were unaware of the fact that the David Clark Company had been pioneers
and industry leaders in the development of Space Exploration clothing
and currently had the opportunity to submit a speculative solution to
the cold hand problem that NASA Astronauts had encountered on their recent
mission.
A
joint development program was set up where Gorix Ltd would supply Gorix
E-CT heating elements for David Clark Company to fabricate into a new
concept glove. Two alternative designs were finalised, the first heating
only the back of the hand in the blood flow areas and the second heating
each individual finger. After many months of evaluation, the David Clark
- Gorix - NASA Glove is still as yet un-flown, but the moment that we
have a guaranteed in space trial, the whole world will know.
Replicas
of the NASA-Glove have been exhibited around the world as part of the
Design Council Millennium Products Award initiative; countries visited
by the travelling exhibition include Argentina, Brazil, Singapore, Korea,
India and France where for a few heart stopping moments it was thought
that the display glove had been stolen from the exhibition to be found
later having been pre-packed for return to the UK, where displays have
been held in the Design Museum and the Design Council's exhibition centre
on Bow Street London.
Space
may be viewed as the ultimate hostile environment, but the depths of the
world's oceans, military aviation and expeditionary work in polar regions
can also produce temperature situations that can very quickly become life
threatening.
Astronauts
and deep ocean divers share a common factor in the protective suits that
they use in their space and sub-marine undertakings, the fact is that
both their suits are heated by warmed water, whilst aviators generally
rely upon a suit with a wire matrix built into the inner fabric of their
flight suits. In the case of the astronaut, the water is in a captive
system and circulated around a matrix of fine pipes interwoven into an
undergarment. In the case of deep divers, the warmed water is flushed
through the suit, the heated water is usually issued from the command
vessel above.
None
of these methods are considered acceptable and in the case of the deep
divers, it is often extremely dangerous. The aim of Gorix Ltd has been
to develop a "user operated, safe, dry, flexible heating system for
all types of clothing". This concept will not only have the safety
advantage of operating from very low voltages, but by being created from
non-metallic composites, will not suffer from degradation by corrosion
and will possess the ability to flex and contour without suffering breakage
in circuit or electrical conductivity,
it will also impart wearer comfort in use.
