This investigation surveyed the potential and established outcomes for future 19-passenger fixed-wing commuter transport aircraft concepts employing battery based Voltaic-Joule/Brayton motive power systems with no additional electrical energy drawn from generators mechanically coupled to thermal engines. The morphological approach was that of a tri...
Conference Paper
This paper presents a methodology for the sizing and synthesis of power generation and distribution (PG&D) subsystems. The PG&D subsystem models developed in a previous work done by the authors were applied within a parallel hybrid electric propulsion architecture using the Dornier 328 as the baseline aircraft. The hybridization took place only dur...
Conference Paper
The ongoing efforts to reduce aviation related greenhouse gas emissions and fuel burn have led to advancements in power generation and distribution (PG&D) subsystem technology. Due to the absence of historical data, PG&D subsystem models must be created from first-order analysis without compromising crucial information on their characteristics.This...
Conference Paper
Full-text available
This paper offers the perspective of Safran Group regarding the topic of hybrid-electric propulsion and power generation. It addresses conventions associated with taxonomy, analysis methods, software tools, possible engineering solutions, as well as offering a notional research and technology pathway. By using overarching requirements gleaned from...

"System design oriented methodologies" are discussed in this paper through the comparison of multiobjective optimization methods applied to heterogeneous devices in electrical engineering. Avoiding criteria function derivatives, direct optimization algorithms are used. In particular, deterministic geometric methods such as the Hooke & Jeeves heuris...
Conference Paper
A "system design oriented methodology" is proposed in this paper through optimization of heterogeneous devices in electrical engineering. To avoid criteria function derivatives, direct optimization algorithms are used for the design, in particular the Hook & Jeeves heuristic method which has proved its robustness on discontinuous and constrained pr...
