Conservation of a WWII Supermarine Spitfire section wing

International audienceThis study focuses on a WWII Supermarine Spitfire aircraft section wing conservation, salvaged from the seabed in 1988 and stored in a private garden. The object was in poor condition so decisions on the conservation, preservation or removal of parts of the original elements were needed. Firstly, the wing fragment was studied to determine its heritage interest and to assess its historical, industrial, technical and scientific values. This object will become a memorial to the pilot who died during the mission, in his hometown. The conservation project aims to find the best solution to both conservation priorities and exhibition needs. Based on cleaning tests on corroded, painted aluminium alloys carried out within the PROCRAFT Project, a treatment was determined. This case serves as an example of how the results of a European project can be implemented in a conservation-restoration process and how industrial conservation theory can be applied to archaeological artefacts.Este estudo considera a conservação de uma secção de asa de um caça Supermarine Spitfire daSegunda Guerra Mundial, resgatada do fundo do mar em 1988 e armazenada num jardimprivado.

Support documents for an exhibition on WWII aircraft wrecks & Artistic and educational programme - Deliverable D7.2

<p>This deliverable reports on the activities carried out within Task 7.2: Support documents for an exhibition on WWII aircraft wrecks and support documents to implement an educational program for young students. This deliverable is inspired by the results obtained in the first meeting partners in Toulouse (PROCRAT-ReportMEETING-20210913-01.doc) and the constitution, afterward, of a scientific committee on the exhibition subject. This deliverable presents the exhibition and educational program scenario and contents.</p&gt

First step in the PROCRAFT Project on WWII Aircraft Heritage: Investigation and Conservation of the Aluminium Alloys

International audienceThe conservation of excavated wrecks or abandoned aircraft is of cultural and historical interest. A first step in understanding the challenges posed by this type of cultural heritage and in finding solutions for its conservation is to document the constituent materials and their subsequent alterations. In the project PROCRAFT, aircraft wrecks from six nations involved in WWII were collected and then studied. Analysis of the elemental composition together with archival research allowed identification of the wrought aluminium alloys used in the non-structural and structural parts of the aircraft. Three manufacturing processes were recognised: rolling, extrusion and forging. The corrosion protection treatments applied during manufacturing of the aircraft parts were also examined, which revealed cladding with a thin aluminium foil, anodisation or the application of primer/paint. Based on typical examples of the alterations that occurred in the metal components, we demonstrate the importance of this original protection against the aggressiveness of the environment

Hangar environment monitoring for corrosion risk assessment and aeronautical heritage protection

The paper shows how the aeronautical heritage is affected by airborne pollutants and the air temperaturehumidity complex. Monitoring meteorological and environmental data in a heritage site intended for protection, these effects are analyzed. The starting point is thus the acquisition of the meteorological and environmental data from the intended hangar with stored historical aircrafts taken part in fights of the second world war. The following step is an evaluation of the penetration of moisture into the hangar environment from outside. This moisture penetration is deducted from wet/dry cycles obtained from air humidity and temperature fluctuations in the hangar environment. In addition, an evolution of the aircraft surface temperature is pertinent to potential moisturizing the aircraft surface. As a measure of moisture penetration, a time of wetness (ToW) is determined indoors. Furthermore, pollutants infiltrated into the hangar environment are derived from a standardized methodology. Beside the pollution infiltration, the indoor generated pollution is estimated per material from which the historic aircrafts are constituted. Because of major material in the aircraft, the deposition rate of indoor pollutants onto an aluminum alloy is determined by means of a standardized statistical model. Finally, monitoring the hangar environment, the heritage aircraft vulnerability to corrosion is estimated based on atmosphere corrosivity modeling
