Abstract
The future of aviation depends on reducing the environmental impact of the aircraft. Unconventional configurations can be the change the industry needs to achieve that goal. Therefore, the development of a tool that allows analyzing these configurations will contribute to their being considered more easily in future designs. This design procedure is based on an aerodynamic model and a weight methodology validated for unconventional tail designs. The load cases selected to size the structure were extracted from the certification regulations in force. In order to validate the methodology, the V-tail configuration was selected as a case study. The fuel savings reached with this tail configurations are around 0.7%, and the reduction in NOx emissions are even greater. Thus, the methodology has been validated and it can be easily adapted to other unconventional tail configurations.
Highlights
The result is that the Breguet range parameter is 25,613.97 km, the takeoff weight is 73,896.84 kg and the trip fuel is 14,927.85 kg. These results present an error of −0.277% in the case of the takeoff weight and −0.428% in the case of the fuel consumption, when compared with the values contained in the database
In order to carry out the sizing of unconventional tail configurations considering design requirements based on the certification regulations for commercial transport aircraft, several tools are needed for estimating aerodynamics performances and weights. These tools were developed in previous studies, and this paper presents the interaction of those tools and their application of a case study of sizing a V-tail configuration
This paper presents a conceptual design tool for sizing unconventional tail configurations for commercial transport aircraft which was calibrated and tested
Summary
There is a growing awareness from most governments around the world about the emission of polluting gases into the atmosphere [1–4]. Despite the COVID-19 crisis, aviation is a resilient market, because it has recovered from similar downturns throughout its history, such as the Global Financial Crisis in 2008 Both air traffic and aircraft deliveries are expected to recover to the previous annual growth levels, between 3% and 4%, for the 20 years [8–10]. To enable this market development and the reduction of emissions, the performances of transport aircraft have been improving during over the past decades, especially, due to developments in key technology areas such as aerodynamics, propulsion, structures, avionics, materials, etc. A field of study is opened in terms of the configuration of the aircraft concerned, being able to analyze unconventional configurations that potentially have benefits from the point of view of performances or emissions of polluting gases [13]
