“…From the perspective of flight vehicle design, the trihierarchical model proposed by U.S. Defense Acquisition University (see Fig. 13 53 ) may be probably one of the clearest descriptions of SoS architecture. The three levels are system of systems level, system level and subsystem level, corresponding to effectiveness, performance and technical parameters.…”

“…In SoSed design, it usually proceeds from definition of capability requirements to determination of the corresponding effectiveness indexes concerning specific mission scenario analysis. For example, in description of typical effectiveness indexes of long-range strategic bombers, Biltgen 53 proposed a number of effectiveness indexes for long-range strike capability requirements: duration of conflict, number of strikes flown, munitions fired, cost of munitions fired, number of red theater ballistics missiles (TBMs) fired, number of blue units lost, number of blue aircraft lost, number of blue long range strike (LRS) aircraft lost, percentage of red time critical targets (TCTs) killed, etc. This case shows diversity of indexes description.…”

In order to obtain optimized flight vehicle concepts which meet system of systems (SoS) operation requirements, designers have to pay high attention to the impact of SoS at conceptual design stage since operation environment goes increasingly complex. Based on this tendency, perspectives and progresses of SoS oriented flight vehicle conceptual design, which is abbreviate as SoSed design, are reviewed in this paper. Such basic concepts of SoS as definition, characteristics, differences between systems engineering and SoS engineering, as well as SoSed design process are introduced, then SoS engineering process model for research and development of flight vehicles and SoSed design wheel model for conceptual design are proposed. Related literature is classified and analyzed in accordance with four major elements including requirements, design concept, design analysis, and trade studies and optimization: typical SoS architectures, description and quantization of indexes are introduced; Application of inverse design in designing concept is analyzed; Modeling and simulation (M&S)-based methods and their applications in SoSed effectiveness evaluation are highlighted; According to SoSed trade studies and optimization related research, the importance of such points as decision-making and using multidisciplinary design optimization for reference are emphasized. Finally, the value of SoSed design is concluded, and five directions which are worthy of attention in this field are presented.

“…It are usually made up of a multitude of independent but interactive systems. In recent years, this field has been growing significantly and SoS theory has been applied in many aeronautical engineering problems, such as air strike [6,7], civilian transportation [8,9] and so on. Different methods have also been applied to deal with these SoS problems, such as surrogate models [6,7], mixed integer nonlinear programming [8], network theory [9], Agent [10], etc.…”

Abstract.To obtain a competitive design in aircraft conceptual design phase, this paper propose an aircraft performance analysis method based on system-of-systems (SoS) simulations. The analysis process includes design space exploration and mission effectiveness analysis and the stochastic nature in SoS mission is captured based on a Monte Carlo method. Meanwhile as an example, the performance of UAVs which are applied in earthquake search and rescue SoS is analysed based on SoS simulations. The results show that the level of aircraft performance which leads to an optimum SoS effectiveness could be designed below the maximum performance. And it is necessary to apply SoS simulations into aircraft conceptual design phase to help designers optimize aircraft performance.

“…Systems are no longer studied separately but in the SoS environment, with the influence of other systems, which often lead to different or unexpected results in contrast with previous cases. In the field of aerospace, the concept of SoS has been applied to solve different problems, for instance, air strike [8,9], civilian transportation [10][11][12], maritime applications [13] and so on. SoS theory also plays an important role in aircraft design [14][15][16], because it gives aircraft designers new inspiration about aircraft design methods, especially in conceptual design phase.…”

Design space exploration has been much neglected in aircraft conceptual design phase, which often leads to a waste of time and cost in design, manufacture and operation process. It is necessary to explore design space based on operational systemof-systems (SoS) simulation during the early phase for a competitive design. This paper proposes a methodology to analyze aircraft performance parameters in four steps: combination of parameters, object analysis, operational simulation, and keyparameters analysis. Meanwhile, the design space of an unmanned aerial vehicle applied in earthquake search and rescue SoS is explored based on this methodology. The results show that applying SoS simulation into design phase has important reference value for designers on aircraft conceptual design.
