Special Issue Information

Dear Colleagues,

To use existing resources effectively in the future, a basic understanding of sustainability should be included in R&D. Although sustainability is examined under the three main pillars of economic, environmental, and social, these three parameters should be examined in an integrated manner.

In the first years of aviation research, only studies on system performance and improvement were carried out. Then, energy-efficient system designs and applications were carried out. In recent decades, economic and environmentally friendly aviation applications have emerged as research topics. Aviation applications can be divided into two subgroups, airside and landside. While the effects of aircraft can be examined separately both on the airside and on the landside, airport studies can be limited to landside applications. To achieve sustainable aviation, we need to carry out aviation studies on environmentally friendly (e.g., producing low emission, carbon neutral), respecting equalities (e.g.; genetics, gender, disability), ecosystem friendly (protecting biodiversity), and using alternative sources (e.g., electricity–heating–cooling with solar, wind, heat pump).

This journal is inviting work concerning sustainable aviation studies. In particular, the collection will focus on eco-friendly aircraft engines, sustainable aircraft materials, aircraft life cycle analysis, alternative energy sources for aircraft, propulsion analysis (e.g., sub-sonic, hypersonic), more electrical aircraft, airport sustainability (e.g, science and social applications), and sustainable airport management (e.g., energy, noise, environmental).

A theory-based aerodynamic model developed and applied to electrified powertrain configurations was intended to analyze the feasibility of implementing fully electric and serial hybrid electric propulsion in light-sport aircraft. The range was selected as the primary indicator of feasibility. A MATLAB/Simulink environment was utilized to create the models, involving the combination of proportional-integral-derivative controllers, aerodynamic properties of a reference aircraft, and powertrain limitations taken from off-the-shelf components. Simulations conducted by varying missions, batteries, fuel mass, and energy distribution methods provided results showcasing the feasibility of electrified propulsion with current technology. Results showed that the fully electric aircraft range was only 5% of a traditionally powered aircraft with current battery technology. Hybrid electric aircraft could achieve 44% of the range of a traditionally powered aircraft, but this result was found to be almost wholly related to fuel mass. Hybrid electric powertrains utilizing an energy distribution with their optimal degree of hybridization can achieve ranges up to 3% more than the same powertrain utilizing a different energy distribution. Results suggest that improvements in the power-to-weight ratio of the existing battery technology are required before electrified propulsion becomes a contender in the light-sport aircraft segment.

Aircraft performance and noise database together with operational weights (depending on flight distances) and operational procedures (including low noise procedures) significantly influence results of noise exposure contour maps assessment in conditions of real atmosphere. Current recommendations of the Standard SAE-AIR1845A allow the definition of flight profiles via solutions of balanced motion equations. However, differences are still supervised between the measured sound level data and calculated ones, especially in assessing the single flight noise events. Some of them are well explained by differences between balanced flight parameters (thrust and velocity first of all) and monitored ones by the traffic control system. Statistical data were gathered to make more general view on these differences and some proposal to use them in calculations has been proven. Besides, the real meteorological parameters provide inhomogeneous atmosphere conditions always, which are quite different from the main assumptions of the SAE-AIR1845A, stipulating inaccuracies of sound level calculations.
