A new summer
is almost past, and it is again time to think about what work needs and
should be done on our Heinkel He 115. The situation is now a little different than what the
was before we finished the work before the holiday. There is an ongoing extensive and intensive
works to finalize museum Bf 109 project. This work will be for a shorter
period lay claim to very much of the area in the workshop. Accordingly, it
be small area free for other work. We must, therefore, in this period limit
our work into smaller parts that can be handled by the area we currently have
restriction in the workshop area gives us extra time to think through what
alternative methods we have available to preserve the aircraft originality of
the longest possible period. It is the second and major players, that work to
preserve the originality of sjøvrak of aircraft, done a lot of work to develop methods
to stabilize the compositions of these wrecks. A method they have developed is to
give the material an electrolytic treatment. We will in the future, and in cooperation
with the other parties involved in He 115 project, make a new survey
of which of the methods developed that may be relevant for our aircraft. Dette
arbeidet vil kreve at vi gjør en lang rekke forespørsler blant de aktørene som
har vært involvert i utvikling og bruk av de forskjellige metodene.
We have during the time that has passed
since last status update of the homepage, got clogged the parts of
the end walls of Heinkel hall which is dressed with timber cladding. The use of
dehumidifier inside the concrete hall has meant that this cladding has dried
out and opened to allow moisture to migrate through all the gaps which are encountered
in planking. The consequence of this has been that the weather conditions on the outside of
hall in a substantial influence to the humidity inside the hall. We can
Now measure that it is both a clearly more stable and significantly lower relative humidity
inside the warehouse.
It is now summer and vacation time and
this will affect the activity around the Heinkel He 115 project a while
It has also been worked on both
with the plane's instruments and to make copies of brackets and mounts for
rudder pedals. These latter should be used as plugs in støypeformer.
The main priority for the Heinkel He 115
the project is to preserve the aircraft so intact and untouched as possible. Yet there is a
fact that the aircraft has remained at the bottom of a inlet in 70 year. Salt therefore
drawn between aircraft many joints. Our challenge is therefore
still finding a method that best safeguards the desire to make small
engagement in the plane while ensuring that aircraft do not over time destroy. We
looking therefore still active over a wide registry to find this. In one
end of this registry finds a possibility of conducting a
electrochemical desalination, while at the other end finds a possibility of
completely or partially to dismantle the aircraft parts. The aircraft's center section is a complex
construction with many very tight joint. It would therefore be difficult
to remove salt from these joints. As part of the studies
round choice of method we have recently spent some time on mapping
how the center section is actually built. This is to provide an overview of
how a whole or piecemeal removal thereof can
Efforts Heinkel He 115 project since January 2018 been hampered
of the Armed Forces Museum is in a process where they will consider future
ownership of equipment that is lent on landfill agreements. It now appears that this
process has come so far that they imposed restrictions on work on aircraft soon
can be raised.
A longer summer vacation coming to an end and we will soon be going again with our weekly Heinkel He 115 activities. The main focus area of work is still measures that can help to preserve the aircraft excellent condition in the years ahead. We have in this context had a major success in wiping out the warehouse. A consequence of this success is that the drying has caused the timber top end walls are opened, and it will here be necessary to install a vapor barrier ( dressing with plastic ).
We will continuously in the future tell more about other plans and initiatives.
Roar Henriksen made a series of experiments with the use of electrolysis to clean steel to corrosion and pollution. Attached are pictures of a file that was found loose in the plane. When we found the file, so it looks like a rust a big lump, that it was not possible to guess what contained. As the pictures show, the file is now again as new.
