1. Abstract Aircraft sizing studies consist in determining characteristics of an aircraft, starting from a set of requirements. These studies can be summarized as global optimization problems under constraints, which express requirements. In this paper, we only consider the constraints satisfaction problem. Our aim is to automatically produce large amounts(More)
Aircraft sizing studies consist in determining the main characteristics of an aircraft starting from a set of requirements. These studies can be summarized as global constrained optimization problems. The constraints express physical feasibility and the requirements to be satisfied; the objectives are market-driven performances of the aircraft. These(More)
This article reports preliminary results obtained with an evolutionary approach to the design of neural controllers for flapping-wing animats. This approach involves a multi-objective evolutionary algorithm and continuous-time neural networks. It has been used to automatically generate controllers securing an energetically thrifty horizontal flight at(More)
1. Abstract The purpose of this article is to present a Chance Constrained Optimization of an unconventional configuration of hybrid-powered-aircraft. The Chance Constrained Methodology is applied using a method of uncertainty propagation based on error distribution moments. The hybrid configuration is compared to a conventional, pure thermodynamic one,(More)
