This chapter details the design and substantiation aspects of a safety critical bonded composite repair to the lower wing skin of a Royal Australian Air Force (RAAF) F-111 aircraft.
The paper presents adapted brief methodology for risk assessment and selection of investment projects, with emphasis to the software design peculiarities and substantiation of the choice of programming language for the application products implementing this methodology.
Substantiation of design parameters of sodium-cooled fast reactor facilities (BN RF) in normal operation modes represent an important task solution of which is necessary for determining safe and optimal reactor operation conditions.
The key technical issues in bonded structures' airworthiness work include: (1) material and process qualification and control, (2) design development and structural substantiation, (3) manufacturing implementation, (4) repair implementation, (5) service experience.
The certification considerations in bonded structures' airworthiness work include: (1) design and construction, (2) structural substantiation, (3) production, (4) continued airworthiness, (5) other elements.
In addition, the cross-sectional study design does not allow the substantiation of causality, the latter necessitating prospective cohort studies.
Thus, progress in collaborative investigations, combining physico-chemical techniques with chemical-modification as well as genetic engineering experiments, enables substantiation of hypothetical work resulting from the design of pharmacophores or homology modelling of P450s.
