The idea of this paper is to propose research methods designed for strength analysis of composite materials which are widely used in load-carrying structures. It is shown that the strength analysis and study of composite materials are carried out in two directions – considering them as inhomogeneous composite materials, representing a regular multilayer medium of alternating reinforcement layers and a polymer binder, and the study of the issue of structural strength, in which composites are considered as homogeneous elastic orthotropic bodies, to which the theory of elasticity of anisotropic media is applicable. These approaches enables to represent the composites in the form of a continuous medium and use the methods of the theory of elasticity of anisotropic media in calculating the acting stresses, which makes it possible to use the influence of the elements of manufacturing technology on the physical and mechanical characteristics.

With an annual growth in travel demand of about 5% globally, managing the environmental impact is a challenge. In 2019, the International Civil Aviation Organisation (ICAO) issued emission reduction targets, including well-to-wake greenhouse gas (GHG) emissions reduced at least 50% from 2005 levels by 2050. This discusses several technologies from an aircraft design perspective that can contribute to achieving these targets. One thing is certain: aircraft will look different in the future. The Transonic Truss-Braced Wing and Flying V configurations are promising significant efficiency improvements over conventional configurations. Electric propulsion, in various architectures, is becoming a feasible option for general aviation and commuter aircraft. It will be a growing field of aviation with zero-emissions flight and opportunities for special missions. Lastly, this paper discusses methods and design processes that include all relevant disciplines to ensure that the aircraft is optimised as a complete system. While empirical methods are essential for initial design, Multidisciplinary Design Optimisation (MDO) incorporates models and simulations integrated in an optimisation environment to capture critical trade-offs. Concurrent design places domain experts in one site to facilitate collaboration, interaction, and joint decision-making, and to ensure all disciplines are equally considered. It is supported by a Collaborative Design Facility (CDF), an information technology facility with connected hardware and software tools for design analysis.
