Article
Full-text available
Bayesian optimization methods have been successfully applied to black box optimization problems that are expensive to evaluate. In this paper, we adapt the so-called super efficient global optimization algorithm to solve more accurately mixed constrained problems. The proposed approach handles constraints by means of upper trust bound, the latter e...
Chapter
In the recent years, aviation is facing with the increasing of fuel price and flights, and the impact is estimated to grow more and more in next years without any action. To reduce its environmental footprint, engineers are trying to design more efficient aircraft, with engines less consuming. However, the classical aircraft’s tube and wing configu...
Article

Hybrid-electric aircraft are a potential way to reduce the environmental footprint of aviation. Research aimed at this subject has been pursued over the last decade; nevertheless, at this stage, a full overall aircraft design procedure is still an open issue. This work proposes to enrich the procedure for the conceptual design of hybrid aircraft fo...

Conference Paper
In the past years, air traffic has continuously increased, with an impact on the emissions level. Thus it has become a major issue for the aeronautical field to face its responsibilities and seek for solutions to lower its environmental footprint. To cope with this problem, research is focusing on the study of unconventional configurations that dep...

Thesis
Full-text available
The increase of air traffic in the last decades and its projections pose a key challenge towards the carbon neutral growth objective. To cope with this societal goal, there is a need for disruptive air transport aircraft concepts featuring new technologies with low environmental impact. Such future air vehicle relies on the various interactions be...

Full-text available
The aviation's goal for the next decades is to drastically reduce emissions, but to achieve this goal a breakdown in aircraft design has to be considered. One of the most promising concepts is the Blended Wing-Body, which integrates aerodynamics, propulsion and structure, and has a better aerodynamics efficiency, thanks to the reduction of the wett...
Conference Paper
Full-text available
The Blended Wing Body (BWB) configuration is seen by many as one of the possible future protagonists of Civil Aviation, both for its potential benefits in terms of Aerodynamics performances and fuel consumption and for the possibility of incorporating Aero-Propulsive integration technology. However, the design of such an innovative aircraft does no...
Conference Paper
Full-text available
In order to reduce CO2 emissions, a disruptive concept in aircraft propulsion has to be considered. As studied in the past years hybrid distributed electric propulsion is a promising option. In this work the feasibility of a new concept aircraft, using this technology, has been studied. Two different energy sources have been used: fuel based engine...

Project
The goal of this PhD project is to define a multidisciplinary design optimization framework for the sizing of a Blended Wing-Body with distributed ducted electric fans. The goal is achieved through different steps: the set up of an optimization framework for the sizing of a hybrid electric aircraft, modification to design process to consider a conventional BWB, and finally a conceptual study of an optimized BWB with hybrid electric propulsion.
