The purpose of these studies was to examine how the type of propulsion system impacted the willingness to fly in a hypothetical scenario. Using a sample of 624 participants from the USA across two studies, it was found, in general, that participants were most willing to fly using traditional jet fuel or a biofuel followed by battery/electric and then solar-powered aircraft. There were no significant differences based on participant gender, any significant interactions nor any significant mediators between the type of propulsion and the willingness to fly. Still, familiarity with sustainability, willingness to pay for sustainability, and environmental commitment were found to be significant moderators. In cases where participants had high levels of the three moderating variables, they were significantly more willing to fly using sustainable propulsion systems than compared to low levels of the moderating variables. The study concludes with a discussion of these findings and the practical applications of this research.

Fuel-efficient flight operation provides airlines with significant competitive edge. Fuel savings in flight can be done by reducing the total aircraft weight. This study investigates the possibility of reducing the amount of discretionary fuel loaded onto aircraft while maintaining the proper safety margin for the flight based on a statistical analysis with empirical data. We found that the data were appropriate for a lognormal distribution. This study adopted a fuel shortage probability standard of less than 5%, according the International Civil Aviation Organization (ICAO) recommendation. We were able to estimate a reasonable quantity of fuel load from this study. According to our data analysis, airlines can save a significant amount of fuel consumption by reducing discretionary fuel. The results of the study may contribute to fuel savings by reducing discretionary fuel loading for aircraft, hence lowering fuel costs for the airlines without internal fuel management system.

Aerodynamics and structural dynamics of the insect wings are widely considered in flapping wing micro air vehicle (FWMAV) applications. In this paper, the aerodynamic characteristics of the three-dimensional flapping wing models mimicked from the bumblebee and hawkmoth wings are numerically investigated under steady flow conditions. This study aims to simulate the one-way fluid-structure interaction (FSI) of these bio-inspired wings by transferring the aerodynamic load obtained from the computational fluid dynamics (CFD) into the finite element method (FEM) solver as a pressure load. The static aeroelastic responses of the wings under the pressure load are compared for different materials, namely, cuticle, aluminium alloy, and titanium alloy at various angles of attack (α = 0°-90°). CFD analysis shows that the hawkmoth wing model at α = 5° has the highest lift-to-drag ratio (L/D). FSI analysis demonstrates that the cuticle hawkmoth wing model at α = 90° undergoes the highest tip deflection.

The aviation sector continues to work in many directions to limit the impact of global climate change on the struggle. In this context, it has achieved significant gains especially with the improvements in motor technologies. However, in order to achieve the desired targets, not only technological but also alternative studies based on alternative fuels have taken the agenda. In this context, fossil fuel improvements also developed as an important field of study. This study primarily evaluated the thermodynamic analysis of alternative fuel-based preferences for a turboprop engine. Then, environmental effects, which are defined as CO2 emissions, caused by entropy production due to irreversibility were investigated. Especially the benefits of alternative fuel preferences were defined by their CO2 emission potentials. At the end of the study, the effects of alternative fuel use with engine performances were evaluated.

The air quality of aircraft cabins has become a significant issue over the past few decades. In general, the existing air comfort regulations and standards for aircrafts are associated with the emissions of CO, CO2, O3 and airborne particulates. However, the emission of volatile organic compounds (VOCs) are not taken into account even though the critical influences of VOCs on people are stated by many researches about the indoor air quality of buildings, cars and rarely aircrafts. The present study is prepared with this concern. It is aimed to emphasise VOCs as an aircraft cabin air pollution, which may cause various health problems and discomfort for the passengers and crews. In this regard, VOCs are introduced by investigating their main potential sources and influence factors, the studies examining VOCs in aircraft cabins are reviewed, and finally, the discussions are made and the possible solutions and suggestions are presented.
