The Impact

ABSTRACTOptimisation of aircraft ground operations to reduce airport emissions can reduce resultant local air quality impacts. Single engine taxiing (SET), where only half of the installed number of engines are used for the majority of the taxi duration, offers the opportunity to reduce fuel consumption, and emissions of NOX, CO and HC. Using 3510 flight data records, this paper develops a model for SET operations and presents a case study of London Heathrow, where we show that SET is regularly implemented during taxi-in. The model predicts fuel consumption and pollutant emissions with greater accuracy than previous studies that used simplistic assumptions. Without SET during taxi-in, fuel consumption and pollutant emissions would increase by up to 50%. Reducing the time before SET is initiated to the 25th percentile of recorded values would reduce fuel consumption and pollutant emissions by 7–14%, respectively, relative to current operations. Future research should investigate the practicalities of reducing the time before SET initialisation so that additional benefits of reduced fuel loadings, which would decrease fuel consumption across the whole flight, can be achieved.

Mechanical Clinching

Lightweight materials, manufacturing technology and the car body structure optimization are the three main approaches to achieve the lightweight constructions. The lightweight materials, such as aluminum or magnesium alloys, are widely utilized in the automotive industry for the weight reduction. Mechanical clinching is used to connect the lightweight materials. In this study, the sheets were joined by the extensible die clinching and flat-clinching. The tensile strength and shear strength of the aluminum alloy 5052 were investigated by the two different tools. Compared with the extensible die clinching, both the tensile strength and shear strength of the clinched joint produced with flat-clinching is higher. And the tensile strength of the clinched joint is up to 54% higher than that of the extensible die clinching.

This article considers an approach to the development of low-waste resource- and energy-saving technologies for the manufacture of large-sized geometrically-complex hull castings from magnesium alloys in combined forms (chill moulds with an internal sand сore). This approach implies solving a set of tasks, such as the provision of conditions for directional solidification and effective risering; the creation of low-cost non-deficient gas protective environments; automatizaton of simultaneous flux-free smelting, modification and refining processes; reduction of gas consumption required for heating moulds; as well as the improvement of labour conditions. In order to solve these tasks, the authors: 1) developed and implemented software application packages; determined the composition of gas protective environments and gas modifying mixtures; calculated the modes of melt processing; 2) developed and implemented automated installations for processing the melt and ensuring the controlled and adjustable heating of large-sized moulds under a predetermined temperature gradient at the height of the mould; 3) developed a technology for recycling magnesium alloy shavings.
