Wanhill, R.J.H. (author), Boogers, J.A.M. (author), Huisman, H.N. (author), Ottens, H.H. (author)In 1995 an air supply manifold support rod from a high-performance turbofan engine failed by bending fatigue. The rod material was Inconel 718, operating at about 550° in an air environment. Diagnostic aspects of the failure (fatigue in bending, Stage I and Stage II fatigue fracture characteristics, and interference colours due to fracture...report 1996

Wanhill, R.J.H. (author), Mom, A.J.A. (author), Hersbach, H.J.C. (author), Kool, G.A. (author), Boogers, J.A.M. (author)The NLR has two high velocity burner rigs for oxidation and hot corrosion testing. A large, custom-built rig was commissioned in 1977 to enable actual components to be tested. A smaller rig for specimen testing was purchased in 1986. Experience with these rigs over the last decade is reviewed.report 1989

Sevenhuijsen, P.J. (author)The measurement of deformations remains an important discipline for the development and evaluation of structures. The report gives a survey of the most important measurement methods now available. Aspects of light which are vital for the understanding of optical methods are treated because these methods become more and more important. The...report 1982

't Hart, W.G.J. (author), Nederveen, A. (author)Constant amplitude and flight simulation fatigue tests have been carried out on sulphuric acid, chromic acid and phosphoric acid anodized specimens. A comparison was made with the fatigue behaviour of bare sheet material. Before fatigue testing the fracture strain of the anodic layers was determined.report 1980

van Leeuwen, H.P. (author), de Rijk, P. (author), Boogers, J.A.M. (author), Huisman, H.N. (author), Wanhill, R.J.H. (author)Circumferentially notched round specimens of 4340 type steel have been plated in a galvanic bath known to be embrittling. The specimens were reclaimed by stripping and baking. Half the specimens were replated in a non-embrittling bath. Reclamation did not remove all traces of hydrogen embrittlement, but raised the threshold stress to such a...report 1979

van der Vet, W.J. (author)Military aircraft flying low level missions in Western Europe encounter a very different environment from that in most of the United States. Industrial pullution causes atmospheric moisture to be highly acid, and the corrosion rate of jet engine components is greatly increased, with consequent high maintenance costs. To help combat this problem...report 1977

Jacobs, F.A. (author), Schijve, J. (author), Tromp, P.J. (author)Fatigue tests under flight-simulation loading have been performed on unnotched Alclad 2024-T3, anodised 2.0 mm thick sheet specimens, manufactured according to several machine-shop processes applied in the air craft industry. From the results it appears that milling is preferable to stamping. Rounding off the edges is also advantageous. The...report 1977

Schijve, J. (author), Jacobs, F.A. (author), Tromp, P.J. (author)Flight-simulation tests were carried out on sheet specimens notched "by an open hole (Kt = 2.66). The material was 2024-T3 in three conditions; Alclad, bare and chemically milled. The crack initiation period and the crack propagation period were considerably shorter for the Alclad material. The significance of the cladding, both for constant...report 1976
