We have lately been working mostly on preparing to move the center section out of the concrete hall and into the workshop.. This is because we will start work on repairing local corrosion damage in the center section. These lesions are mainly localized to the areas within the wing, float and engine mounts. This will be a time consuming job. If we are lucky, we will not have to do other and more intrusive work on the center section. Ultrasound examinations, as IKM Inspection AS has done for, shows us that fortunately there is little corrosion on the most complicated parts of the support structure in the center section.

The center section will take up a lot of space inside the workshop. To free up this space, it has been a priority to work with the Caproni nose section. The latter has of course had some consequences for the progress of the work with He 115 cockpit and nose section. The first relocation of the center section inside the concrete hall has now been completed. The plan further now is to saw out a five meter wide opening in the west- the wall of the concrete hall. Through this we will then roll the center section. When the center section is out of the concrete hall, we must immediately close the opening in the brick wall. The process of sawing out the hole in the concrete, move out the center section and then close the hole in the concrete wall must happen in one and the same day. We plan to do this during the autumn.

The center section has been moved and is here ready to be rolled further out of the concrete hall

When we raised the plane, we found in the Kanzel parts of a measuring instrument that we did not understand the use of. We understood that these were parts of a drift meter, but we were unsure how this had been mounted in the plane. The drift meter was then given a temporary preservation and then stored. On the starboard side at the front of the Kanzel there is a rectangular hatch. Behind this hatch we found the remains of a magnesium bracket and the remains of a cloth cuff. We did not understand what this hatch and bracket had been used for. In pictures by Heinkel 115 this hatch appears, with few exceptions, as closed.

Then we are lucky and are contacted by Marc Bressan who lives in Switzerland. Marc Bressan has a very solid knowledge of and experience with German aircraft instruments. He had restored and built up a complete drift meter himself. Marc offered us to share with us his extensive knowledge and documentation about He 115 Tribsgërete. He sent us a bunch of pictures that showed us what a complete system should look like and work.

The information we received from Marc showed us that we needed a lot to have a complete system for drift measurement.. Marc now offered to complete and donate to us parts he had left over from the restoration of his own Tribsgërete. With these parts we were now in possession of a complete system for drift measurement. The drift meter that we found in the plane in 2012 was only temporarily preserved and did not open up for interior cleaning and preservation. Marc opened this for us and did a thorough internal preservation of the meter for. This facility for measuring drift, will when these are mounted in the aircraft show these well again forward in the Kanzel. We owe Marc Bressan a very big thank you for the help the project has given.

This equipment, along with everything else we have found on board, shows that a very well-trained crew was needed for them to be able to operate and benefit from all the aircraft's systems.

The tube to the drift meter system was the only one we found when we were in 2012 raised the plane.

The following pictures we have mainly received from Marc Bressan:

Since this summer, we have continued to work on preparing the Kanzel to be able to mount it again together with the cockpit section..

During this work, it has been necessary to open up a few records / rib joints. This is to clean these for ongoing corrosion. To secure the pipe structures against further internal corrosion, Owatrol has been injected here.

Much work has also been done to preserve and rebuild original instruments and other components such as switches and electrical components.. Many of these components are now back assembled in Kanzel.

During the time on the fjord bottom, the cable street for the pipe network was completely corroded away and a new similar cable street has therefore been made..

New three cassettes for storing light cartridges have also been made. Furthermore, a lot of work has been done to clean and rebuild MG 15 spectacle magazines.

We will soon be there where further work with the Kanzel will depend on this being installed together with the cockpit section. This is because there are several large systems that run through from the Kanzel and backwards through the cockpit.

In parallel with the work with Kanzel, work has been done to prepare the center section for NDT investigations of the supporting beams.. To provide access to be able to measure rear girders, the rear edge of the center section has been loosened from the main structure.

IKM Inspection AS gave us 11. October free of charge an ultrasound examination of the beams. Incredibly, these measurements showed insignificant variations in material thicknesses. This gives us good hope to be able to avoid making very large interventions in the center section. We are now working to prepare for during 2022 to lift the center section out of the concrete hall and into the workshop.

In this post, we will show some pictures of the parts that are now in place in the cockpit.

Behind everything that is now mounted in the cockpit is a lot of work that the pictures can not make visible. This applies to both work with electrical components, work with instruments, as well as work with photos and documentation.

In addition to the work on the cockpit and the Pulpit, we have also begun to prepare what we will have to do with the center section in the years to come..

It is a guiding principle that we should as far as possible utilize all the original parts that we found in the plane when it was raised in 2012. At the same time, we try as far as possible to make things work again.

We all wish you a good summer…

It has been since the summer 2020 been working on making a new instrument panel in the cockpit. Of the original panel, we only have a piece a few cm2 in size. This piece has nevertheless given us some information, among other things. what color the panel was when the plane crashed.

Luckily we found when the plane was lifted in 20212 all the original instruments that have been in the panel. It's in previous posts, on this page, accounted for the work of rebuilding these instruments. The condition of these was variable, but mainly there is still a very high degree of originality on the instruments that are now mounted in the pilot's instrument panel. The exceptions are radio bearing compass and fuel gauge that were not found in the aircraft in 2012.

We are looking for a more comprehensive technical documentation for Heinkel He 115 than what we already have today. Our stock of technical documentation is currently limited to a collection of incomplete drawings and the flight manuals for sale at Archiv- Haffner. What we most hope to find is to share the manuals that all Germans of the current vintage aircraft types were equipped with. Beyond Spare Parts List / parts lists, we are of course interested in all information about Heinkel 115.

It is possible that at the end of the war there was no interest on the part of the victorious parties to take care of He 115 documentation. This is possibly because the aircraft already represented a then "outdated" technology. Therefore, this documentation was often left to its own fate.

Here in Norway, too, it seems as if Heinkel 115 the documentation has not been well taken care of. We have not been able to trace technical material that may have been left at the conclusion of the peace in 1945.

We have another hope that there may be more material in Sweden, and has therefore made several inquiries yours.

Our German friend, writer and author Christian König makes a great and impressive effort to help us with the search for documentation about the aircraft type. He uses his large network to call for material. Christian has also written articles in the magazines Flugzeug Classic and Luftwaffe Revue, where he calls for information on a replacement list for Heinkel 115.

We have received the good news that Heinkel He 115 The project by the National Heritage Board has been allocated funds for the work on the aircraft's center section. The allocation is limited to 40000 kroner and will be used for preparations and construction of a gig that we need to be able to work on the center section's supporting beams.

Before we can start the work of building such a gig, we will first map the extent of corrosion damage to the supporting beams.. To make such a survey, we consider using NDT as a method. On that occasion, we are already in contact with IKM Inspection AS who have been on an inspection and looked at the center section. Their preliminary opinion is that the use of ultrasound as a method will give us the best result. They will now make a more comprehensive assessment of how they can best make a survey of corrosion damage in the supporting beams..

It has again gone a little while where it has worked very well with Heinkel 115 project. The focus during this period has been on working with a new instrument panel, completion of work on building a new hydraulic hand pump, the continuous ongoing work to preserve electrical parts, as well as further work with documentation, photos and sharing archive. Work on a new engine buck has been completed ended in anticipation of us being able to solve the problem of missing it one of the aircraft's engines. Work continues on preparing to be able to start up the work that will have to be done with the center section.

We also have started up again looking for parts lists / catalogs / Spare part list / service-parts-list for flyet. Both Norway and Sweden operated these aircraft, and we have not yet given up the hope of tracking these down in one of these two countries. It's through Christian König also made attempts to trace these catalogs through his wide network of contacts in and outside Germany. Among other things, there will be an article in FlyPlast and hopefully also I FlugzeugClassic m.m..

The year 2020

The year 2020 was a good year for Heinkel 115 the project through which many positive things have happened.

We have for several years had restrictions on the type of work we could do on the plane. During the past year, the Armed Forces Museums have largely been abolished these restrictions.

It formerly Heinkel 115 the steering group has been closed down. As a replacement for this a support group has been established with members from the Friends' Association, as well as two conservators engaged by the Jærmuseet. This solution gives us that working with the aircraft an easy access to a very versatile experience and competence.

It also in over the past year there has been a unanimous understanding that it can be necessary to make some interventions on the center section. This mainly applies to supporting beams, with associated attachments for wings and floats. This has led to it now is working to find solutions for how such work can be completed. Our goal is still to make small interventions and preserve as much as possible much of this section.

It has Throughout the year, work has been done on a number of different sub-projects. I de cases where equipment is completely destroyed, we integrate what may be left of the original equipment in the new one being built.

An example is the work that has now been completed to build a new hydraulic hand pump for flap and opening of bomb hatches etc.. Of the original pump, only handles remained, mechanical transfer to stamps, pistons and end caps. Said parts are built of high-quality materials and had done well down on the fjord bottom. All the pump housing and cylinders, on the other hand, were almost completely corroded.  Pump housings and cylinders have now been rebuilt and the pump can now again be used to pump oil. The above mentioned remaining parts have been integrated in the new pump.  

It is also throughout the year made a new instrument panel for the cockpit. Although most of the original panel was gone when the plane was lifted, will still the new panel be equipped with original instruments. These are instruments that were found in the aircraft and which has now been preserved and in some cases partially rebuilt.

Through At the same time, we have gained a good overview of the work with the instruments which instruments and other similar equipment have been in the cockpit of the aircraft and nasal section.

Another of the bigger things that have been done through 2020 is the work of rebuilding the system for suspension and transmissions from the rudder and toe pedals. Also here is remaining original parts have been integrated into the new finished product.

It has also become worked hard to preserve original electrical equipment. These are things like circuit breakers, switches, terminal blocks and many other smaller electrical components. The work is a time-consuming work of patience that is now really beginning to show again in form of finished preserved parts. These have either already been reassembled in the plane, or in stock ready for use..

The big and extensive cableway along the port side of the cockpit was also completed early in 2020

The outer the section of one engine stand was completely missing when the plane was lifted in June 2012. This is because one engine was salvaged before the plane sank in December 1942. It the missing section has been rebuilt during the autumn. At the same time, we have what we have of original brackets and other equipment for the motor brackets have been reassembled on the engine jacks.

Photo sharing archive and documentation is a time-consuming task that runs as long as the project ongoing. It is also through 2020 been working a lot on these things.

When the plane was raised in June 2012 a few smaller parts were left at the site. It was last year, several ROV dives were made at the crash site in Hafsfjord. Although the plane was unusually complete sea ​​wreck to be, also missing our plane things that can not be found elsewhere. A new application has therefore been sent to raise He 115 parts from Limingen.

2020.10.22

Efforts Heinkel He 115 has been going on all summer without the usual break that the participants' summer holidays tend to bring. Such has also we have been influenced by Covid 19.

Much work has been done to create a new instrument panel cockpit. We have only a few cm of the original panel2 left off. Even if the panel is new, it will still be filled up by the original instruments who was on the plane the day it crashed.

A lot of impressive work has also been done to recreate parts for suspension of side rudder pedals, both for pilot and for navigator. Some of the parts of this large system were almost completely gone when the plane was lifted . Again has managed in a good way to intrigue some new parts in among the many originals parts.  

A curiosity is that it has managed to get light in again the hand lamp that was placed in a box in the back of the telegraph operator cockpit.

Work is also currently underway to make new the missing parts to one engine stand.  These are parts which we are missing since one engine and both floats were salvaged right after that the plane had crashed.

It is also gratifying that we will soon be able to continue the work to repair the corrosion damage in the supporting beams in the center section. The idea is to do necessary interventions to preserve the residual strength of the load-bearing structure, and in a as far as it is justifiable, to preserve the rest of the center section. The idea behind this approach is to be able to preserve as much of it as possible center section as original.

Over time, we have searched extensively for information on an instrument with a associated system that was located on the starboard side of the Kanzel. We have now received a great and informative answer from Armin Züger in Helsinki. He had read our request in a previous post on this website, se link; http://heinkel115.com/2020-06-11/?lang=en

Attached you can read Armin`s answer.

 There was some open questions about a so-far unknown instrument, related to torpedos.

There is an operation manual: D.(air)T. 7212  "Description, Operation and maintenance of the PVC drop weapon 1006 A“ (which I have attached as a pdf document) that might shed a bit more light in this.

In the picture there some words “Scharf Torpedo Fallschirmlot Blind” on the unknown instrument.

“Scharf” and ”Blind” means basically “disarmed” and “armed” (i.e

Mixed,options applicable to his clinical condition and the related sildenafil dosage.

. defining if the torpedo will explode or not explode finally).

“Fallschirmlot” is another expression for Luftmine (parachute mine, LMA and LMB ), you will find this also in the manual

Now the interesting part:

The document contains also a schematic picture of a He 111 cockpit. There is one lever named BlindScharfhebel. And I guess this is what the unknown mechanism of your He 115 is. It’s a lever to arm/disarm the torpedo (in case of the He 115 maybe combined with some other functionality).


2020.06.11

Armed Forces Museums have for some time placed some restrictions on what types of work as we were able to do on the plane. These restrictions have now been lifted, and we can now continue the collaboration with the Jær Museum on the further work on the aircraft.

Pending that the said restrictions should be lifted we have continued to work clean and preserve parts as in 2014- 2015 took off from the aircraft cockpit and nose section. During this past winter season has several of these parts been reassembled in the aircraft

difficulties, if you have such a problem, I would beage of the patient. In general, sildenafil when sildenafil dosage.

. Large parts have also been reconstructed as was completely corroded when the plane was salvaged 2012.

Now is exhibition season again in progress, and the cockpit and nose sections are rolled out from the workshop and into the exhibition hall. Here it must stand the exhibition season is over again. Then it will be re-entered the workshop again.

It's working continue to finish outstanding work on the objects that have become preserved or made new through the winter season. In summary, it is quite clear that there has been a lot of positive things over the last six months plane.

We have been working on the aircraft ever since 2012 began to get acquainted with the aircraft and its equipment. Nevertheless, new questions about equipment are constantly emerging that we do not fully understand what has been used. Since we now work extensively with Kanzel and the cockpit sections, the most equipment that has stood here we are concerned about. By studying images from the days after the uplift, we have become aware of an instrument that has been linked to the insight and triggering of the torpedo. So far we have not been able to finally identify which instrument this has been. Attached are pictures taken by the instrument in June 2012.
