Preliminary Study of Emissions Regulation Effects on Future Commercial Aircraft Designs

Abstract

Abstract-Conventional aircraft designs have long been highly successful for commercial passengers transport markets. In recent years, there are researches carried out to explore a few revolutionary concepts such as the blended wing body. With expected stricter environmental regulations to be imposed by the aviation regulatory bodies for future flight operations, questions arise on the relevancy of conventional aircraft designs to remain competitive in years to come and on whether the search for new revolutionary aircraft designs has become necessary. This study aims to assess the situation by analyzing the projected emission performance of conventional aircraft designs through changes of their parameters. Overall, the results indicate that conventional aircraft designs face a tough chance to remain competitive when the proposed regulation takes place and a more aerodynamically efficient design is necessary.

A Sensitivity Analysis on the Range Equation of Hybrid-electric aircraft

“…The sensitivity analysis was carried out using carpet plots. Lift to drag ratio for a body is defined as lift generated by a body moving through air divided by aerodynamic drag [10]. For a powered aircraft, it is generally specified for a straight and level flight.…”

“…This ratio is determined using computational fluid dynamics, computer simulations or experimentally using a wind tunnel. Historical data [10] was used to project lift to drag ratio values for upcoming decades which is shown in a plot (figure 3) between lift to drag ratio and years. The futuristic Boeing truss-braced wing [11] for X-66 experimental aircraft is expected to have long, thin wings stabilised by trusses, thus improving lift to drag ratio.…”
