“…The current optimization technology can already be extended to the integration analysis of multidisciplinary as aeroelasticity, avionics, flight performance, etc. [9]. Schuhmacher et al [10] used NASTRAN SOL 200 to design the wing box of Fairchild Dornier Regional Jet with multidisciplinary design optimization (MDO).…”

Due to the demands of personal travels and entertainments, light airplanes and small business aircrafts are developing rapidly. Light airplane structure is simple; however, it lacks crashworthiness design, especially the considerations on the impact of energy absorption. Therefore, in an event of accident, significant damage to passengers will be usually incurred. Airplanes made of composite materials structurally have high specific strength and good aerodynamic configuration. These materials have become the primary choice for new airplane development. This study mainly explores the topology optimization analysis of the light aircraft's cockpit made of carbon fiber reinforced composites. This paper compares the compression amounts in the original models of composite material and aluminum alloy fuselages with the models after optimization during the crash-landing, in order to investigate the safety of fuselages made of different materials after structural optimization under the dynamic crashing. This study found that the energy absorbed by the aluminum alloy fuselage during crash-landing is still higher than that by the carbon fiber reinforced composites fuselage. On the other hand, the aluminum alloy fuselage after topology optimization could have an energy absorption capability enhanced by 40%, as compared to the that of the original model of aluminum alloy fuselage.

“…To attract and retain custom, each airline needs to differentiate from its competitors. Customer requirements are recognised as a key motivation in business and design [10], with typical value drivers being comfort and the customer experience, services, sustainability and airline efficiency. Passengers are the airline's principal customers, although they are but one of several types of stakeholders, which include aviation authorities, airport operators, air-traffi c control and security agencies.…”

“…These parameters were considered in a recent project run by Airbus [10], where the attention was on the aircraft cabin of the future, which will need to deliver on the multiple requirements using experiences from the A350 XWB and future cabin design concepts. An aircraft concept for the Airbus of the future is illustrated in Fig.…”

Design and engineering have worldwide impact. The products and systems generated affect every level of our lives. In a competitive world where the prosperity of local industry waxes, wanes and emerges in new forms, temporal strategies and policies for survival and gain inevitably emerge. It is in this context that engineers and designers operate their exciting trades, with consideration of multiple functional attributes in any given application. This may involve attention to technical, aesthetic, economic, social and latent function and their often complicated interrelationships, with one attribute affecting the performance of others in a significant manner. The value of each attribute needs to be maintained at the design stage in order to deliver worldwide competitive products, systems and services. It is in the conceptual, detailed design, fire-fighting and application phases that engineering analysis shows its potential, time and time again, to deliver order-of-magnitude as well as validated estimates for quantities. The tools of engineering provide essential input and influence for the design process. These tools can be operated with diligence and exacting analysis, as well as in the fast-paced conceptual stages of any project, in order to explore the ‘what if’ and to provide a physical basis for an idea, as well as the impetus to give that idea the justification for the resources it requires for elaboration.

Purpose Python codes are developed for the versatile structural analysis on a 3 spar multi-cell box beam by means of idealization approach. Design/methodology/approach Shear flow distribution, stiffener loads, location of shear center and location of geometric center are computed via numpy module. Data visualization is performed by using Matplotlib module. Findings Python scripts are developed for the structural analysis of multi-cell box beams in lieu of long hand solutions. In-house developed python codes are made available to be used with finite element analysis for verification purposes. Originality/value The use of python scripts for the structural analysis provides prompt visualization, especially once dimensional variations are concerned in the frame of aircraft structural design. The developed python scripts would serve as a practical tool that is widely applicable to various multi-cell wing boxes for stiffness purposes. This would be further extended to the structural integrity problems to cover the effect of gaps and/or cut-outs in shear flow distribution in box-beams.
