Heinkel 115 project

It was a great moment, Saturday 2. June 2012, when Heinkel He 115 b / c was lifted out of Hafrsfjord. A large number of spectators had gathered in the old German seaplane harbour, the weather was great, and the whole scene was reminiscent of a festival. Then finally we could see the first propeller blade sticking up through the surface.

Finally out of the water after almost 70 years on the fiord

The plane lifted out of the bay has code letters 8L FH and werkenummer 2398. It belonged to 1 Staffel / Küstenfliegergruppe 906. This is the first step in a long process. Many volunteers and local businesses have given great contributions. And the effort is a success, it is a very rare fly, in an unexpectedly good condition, as retrieved from the bay.

Such as this aircraft has set out in the time just before it crashed 28. December 1942

Efforts to salvage the plane is a comprehensive project that is run by members of the Friendship Association Aviation Museum Sola. That raising feasible due to much a comprehensive support from a number of companies in North Jæren. These support the project with money or goods and services, without charge or at greatly reduced rates. Without this generous support, it would not be possible to implement the project. In addition, divers performing raising ,and contributes with its extensive network, a very impressive job.

The aircraft is a unique in the sense that it is not known that there are other preserved specimens of this type of aircraft in the world. The exception may be a possible wrecks, rumors says, can be privately owned in France somewhere. For Norwegian aviation history, this aircraft also of great importance, when it 1939 was acquired 6 He 115 to the Norwegian Armed Forces. There is a large aircraft, and preservation and reconstruction is a large and comprehensive project. defense museum, which owns all abandoned German munitions in Norway, has entrusted the responsibility for the aircraft to the Aviation History Museum Sola.

Heinkel 115 The project

This is a project that is organized under the Aviation Museum Sola, and whose mission is to stand for the further work on the plane.

The project's steering committee

In order to ensure a professional and comprehensive management of the project, the museum has established a steering committee with members from the Foundation Aviation Museum Sola, Jærmuseet and Venneforeningen Aviation Museum Sola. The group takes care of the planning and all significant decisions related to the work of Heinkel.

The way forward

The aim is to treat the plane so that this ensures a longer life. Therefore one must reduce the risk of new corrosion after the work is completed. An airplane which has been long in the sea will be vulnerable to corrosion, even after it is taken ashore and cleaned. Therefore, one can never regarded the project as completely finished. After completing the reconstruction of the plane, it will probably be a need for a regular maintenance program to hedge against further decay.

The plan is that the museum should show up a whole aircraft. That is to say that we want to put it on floats and put on plates and other parts that are missing if we find this necessary. At the same time it is desirable to preserve as much of the original in terms of structure, surface treatment and other. It is not decided to what extent it is necessary to take all parts apart. All sections of the plane will be carefully examined and assessed individually. Based on a state assessment will decide what to do. The project team has contact with external experts who will assist in this work, both in the university environment in Norway and the Aviation Museum in Europe.

Although the plane is in good condition compared to other aircraft taken from the sea, there will be a considerable effort to maintain the aircraft in the desired condition.

Project plan and project phases

Phase 1

Planning, raising and storing plane in freshwater tank. To store the aircraft in a freshwater tank was important for several reasons. It prevented the aircraft paint and other vulnerable details dried out and screws stuck, and salts crystallize, with the fatal consequences it would get. A hope and getting washed out much of the salts. This intermediate storage has also given us time to prepare for the project's second phase. One sees now that fresh water tank has filled the function it was intended, but it is evident that the aircraft should not be there longer than absolutely necessary.

Phase 2

Cleaning and protective treatment of the aircraft five main- sections. All aircraft's five main- sections taken out of the fresh water tank, thoroughly cleaned and conserved. It is important that the cleaning and conservation are implemented as soon as possible. This is to limit the decay and thus ensure jewel such optimum safeguarding as possible.

Phase 3

Reconstruction / mounting. The scope of this work is dependent on how extensive disassembly we must implement in order to preserve and ensure the aircraft of the future. This assessment is done in parallel with the work during the main phase. If it becomes necessary with a major disassembly and reconstruction of the aircraft, is this outside the museum's own capacity. That is why, among others. established contact with the International Aviation and Army History Museum Fondation in Hereg, Hungary. This is a workshop, which has successfully been used by both the Norwegian Aviation Museum in Bodø and Deutsches Technik Museum in Berlin.

The status of the aircraft's state

In Hafrsfjord plane has been immersed in sea water of high salinity, but probably with a low oxygen content. The plane has had a remaining engine with a gearbox which may have been cast in magnesium. The low oxygen content in seawater, along with a cathodic protection from magnesium in girboksen, may have helped to protect aircraft. In addition, the primary structure parts that have a very good corrosion protective coating. The more secondary structural members have not received the same corrosion protection. It is here that one finds the greatest corrosion damage.

The landing and stay at the bottom is applied to the primary structural members less mechanical damage. It is essentially part of the tail and left wing that has structural damage.

What has been done since the raising

In an effort to preserve the aircraft's condition built Venneforeningen before raising a large betongkar. Here the plane remained submerged in fresh water, bl.a. to get to thin out the salt concentration. The plane was in the days after the salvage dismantled down to its five main- sections.

autumn 2013 was the 10 meter abdomen taken out of the fresh water tank. Jærmuseet Asked at your disposal a conservator, which accounted for a thorough cleaning of the parts. It was used Lanolin to conserve parts. Abdomen is now part of the museum's exhibition.

Nose and cockpit

24.april 2014 were nose and cockpit section taken out of the fresh water tank. Remaining equipment is dismantled. These are mainly stored in smaller water tanks in anticipation of a more thorough cleaning and preservation. The goal is to take care of most of the equipment, and inside lacquer and labeling.

We will try out new methods and techniques for use in such work. The goal is to find ways to make it work on that can be continued in other parts of the plane. Inside the cockpit section, we have successfully used blasting with dry ice as a method for cleaning.

17. September the nose and cockpit sections separated. They are now ready for the experiment with an internal cleaning using ice blasting.

Motor

The remaining BMW 132 K motor was immediately salvage cleaned and dismantled. This is now conserved, and will be rebuilt as far as we're able to obtain parts for this work.

The center section and wings

In October 2014 was the water in the concrete tank was drained for the last time. We are currently working to clarify the center section, wings and rudders and a number of other major components, to be stored dry. The work is performed on the concrete vessel previously used to store aircraft water immersion. This is now converted into a workshop and warehouse for Heinkel.

other parts

In connection with the dismantling of the aircraft in June 2012 it was necessary to take a number of smaller components. These are stored in smaller freshwater tank. Some of the parts are given protective treatment and prepared for separate exhibits. By reconstruction must be replaced in the plane.

Methods and techniques

We want to document the methods and techniques we use in our work. It will be made short presentations of way work on individual parts or sections are performed on. You can search for this material by the right side choose the category Methods and techniques.

Economy

The museum will be dependent on the new support for putting the aircraft capable so that it can emerge as an exhibition object it's second to none anywhere in the world, link to the presentation brochure; Presentation of the Heinkel He 115 project

The museum has previously completed a number of major restoration projects with people. The resources, however, is severely limited, and most work is done by volunteers.

Whatever is to be done will be the talk of major financial and personnel challenges to reach the finish with the desired result. A reconstruction will be resource intensive, whether a job being performed internally or external assistance.
