SAFECOMP - Electronic distribution of airplane software and the impact of information security on airplane safety
Lecture Notes in Computer Science, 2007Co-Authors: Richard Robinson, Mingyan Li, Scott Lintelman, Krishna Sampigethaya, Radha Poovendran, David Von Oheimb, Jens-uwe Dr. Bußer, Jorge CuellarAbstract:The general trend towards ubiquitous networking has reached the realm of airplanes. E-enabled airplanes with wired and wireless network interfaces offer a wide spectrum of network applications, in particular electronic distribution of software (EDS), and onboard collection and off-board retrieval of airplane health reports. On the other hand, airplane safety may be heavily dependent on the security of data transported in these applications. The FAA mandates safety regulations and policies for the design and development of airplane software to ensure Continued Airworthiness. However, data networks have well known security vulnerabilities that can be exploited by attackers to corrupt and/or inhibit the transmission of airplane assets, i.e. software and airplane generated data. The aviation community has recognized the need to address these security threats. This paper explores the role of information security in emerging information technology (IT) infrastructure for distribution of safety-critical and business-critical airplane software and data. We present our threat analysis with related security objectives and state functional and assurance requirements necessary to achieve the objectives, in the spirit of the well-established Common Criteria (CC) for IT security evaluation. The investigation leverages our involvement with FAA standardization efforts. We present security properties of a generic system for electronic distribution of airplane software, and show how the presence of those security properties enhances airplane safety.

Thoughts on the scatter associated with the growth of both small naturally occurring cracks and long cracks
2014Co-Authors: Rhys Jones, Dinaz Zenobia Tamboli, Pu Huang, Daren PengAbstract:The ability to understand the factors that contribute to the scatter inherent in the fatigue lives of metallic structures is critical both to ensuring Continued Airworthiness and to designing optimum structures. This paper focuses on the effect of variations in a material's cyclic stress intensity threshold (ΔKthr) on fatigue crack growth. It then shows that the NASGRO equation can be used to account for the scatter in the crack growth rate seen in a number of classical fatigue experiments. The nature of the tests needed to understand the scatter seen in fatigue crack growth in operational aircraft is also discussed.

Understanding crack growth in fuselage lap joints
Theoretical and Applied Fracture Mechanics, 2008Co-Authors: Rhys Jones, Lorrie Molent, Susan PittAbstract:Abstract The problem of multi-site damage and multiple interacting cracks is one experienced by many aircraft manufacturers and operators. This paper focuses on understanding the phenomena, and on developing a predictive capability that can form the engineering framework for maintaining Continued Airworthiness. To this end the present paper uses a simple formulation based on the Frost–Dugdale crack growth law to study the problem of cracking at fastener holes in fuselage lap joints and shows that the predicted crack growth history is in good agreement with both experimental results and with fleet data.

Application of constitutive modelling and advanced repair technology to F111C aircraft
Composite Structures, 2004Co-Authors: Rhys Jones, Lorrie MolentAbstract:Abstract To overcome cracking in F111 aircraft in service with the RAAF it was necessary to: (1) Provide an alternate load path so as to partially by pass the critical region; and (2) Change the geometry of the local region, thereby reducing the K t . To achieve the first a boron epoxy doubler (reinforcement) was developed. To meet the requirements for Continued Airworthiness it was necessary to determine the associated inspection intervals. To this end it was necessary to obtain the residual stress, after CPLT, and the stress “per g” both with and without doubler and with various grind out configurations. Since during CPLT the critical region undergoes gross plastic yielding to obtain this information requires a detailed elastic–plastic analysis. However, classical techniques for modelling this cyclic behaviour have inherent difficulties in representing the response to large cyclic inelastic strain excursions. Indeed, the use of classical analysis techniques resulted in an inspection interval, for the modified structure, of under 500 h. This contrasts with service experience which has shown that there is little further cracking. Indeed, for modified aircraft there has been no further cracking since 1985. To overcome this shortcoming an advanced “unified constitutive” model was used.

On the Glinka and Neuber methods for calculating notch tip strains under cyclic load spectra
International Journal of Fatigue, 2000Co-Authors: M Knop, Lorrie Molent, Rhys Jones, Chun H. WangAbstract:Abstract To maintain the Continued Airworthiness of civil and military aircraft it is essential that the fatigue behaviour of components subjected to complex multiaxial stress conditions be both understood and predicted. This topic is extremely complex and numerous criteria ranging from the purely empirical to the theoretical have been proposed. To this end it is necessary to know the localised stress–strain history. Whilst a detailed finite element analysis can be performed it is often very time consuming. Consequently, the present paper focuses on the development of a simple method which combines modern constitutive theory with either Neuber's, or Glinka's, approach to calculate the localised notch strains. Here particular attention is paid to the effects of cyclic loading, mean stress relaxation and its effect of fatigue damage.

Study of multi-site damage of fuselage lap joints
Theoretical and Applied Fracture Mechanics, 1999Co-Authors: Rhys Jones, Lorrie Molent, Susan PittAbstract:The downturn in the world economy coupled with the cost of new aircrafts has meant that there are now ageing fleets whose Continued Airworthiness requires special attention to corrosion treatments, repair design, fatigue and fracture analysis, and improved crack detection techniques. To assist in this goal the present paper first summarises recent Australian efforts into the development of a simple experimental test specimen which is capable of reproducing the crack growth and failure mechanisms seen in the fuselage lap splice of a wide bodied transport aircraft. The development of a composite repair to overcome these phenomena is then discussed.
