“…12 again). Figure 13 shows that it is necessary, for an effective Conceptual Design, to have the definition, obviously at a preliminary level, of the main on-board Systems; mainly because of the great relevance of on-board systems definition for a conceptual design, see (Chiesa et al 2012b;Fusaro et al 2016;Prakasha et al 2016). Figure 14 shows that, after defining the several on-board system layouts, it is possible to preview (and this is one of the most typical Aircraft Architecture operations) a preliminary installation of the systems in the aircraft.…”

The aim of this paper is to present the recent experience in the education of Aircraft Engineers of a very peculiar aspect, the Airplane lay-out definition, in order to provide students at first with a global vision of the plane, the capability to operate in lay-out definition and to be conscious of such a context, clearly interfaced with all other design activities. At first, it is discussed how relevant and essential Aircraft Design Education is in a wider Aircraft Engineering Education context. Then it is described how Design is comprehensive for both Quantitative and Qualitative definitions, pointing out that Qualitative definitions, like an Airplane Layout (at a Subsystems level of the “block scheme” too), are extremely relevant but very difficult to acquire. So, an idea to start to educate young Engineers (PhD Students in particular) has been developed and, for the first time, has recently been held at our Politecnico. The organisation and the program of the course are described, with detailed attention to peculiar topics or practical exercises considered to be particularly useful to reach the educational objectives. In such a way a sort of logical guideline to starting to sketch an initial layout is acquired by the students. It is relevant how the undeniable interest generated by historic airplanes can be a powerful means to push Students to try to understand architectures and, eventually, to elaborate new solutions.

“…It is worth to notice that the System of Systems architecture and the vehicle layout proposed are the results of several high level trade-offs. For additional detail, refer to Fusaro, 14 De Vita et al, 16 and Fusaro et al 17 Case study: A single stage with VTOL capabilities aimed at performing parabolic suborbital flight…”

“…Indeed, the identification and simulation of the re-entry trajectory of this object in the worst scenario will provide the designers with the major data about structural and thermal loads during the trajectory. In this case, the exploitation of an ad hoc built-in tool for the trajectory simulation of suborbital vehicles, developed and presented by the authors, 17 would be supported by the results of existing commercial software like ASTOS Õ . These analyses will provide useful information for the design of the hot structures and the thickness of the ablative materials that will eventually cover the lower surfaces of the vehicle and, of course, of the cabin escape system.…”

“…First of all, this implies that proper simulation model should be built and run in order to derive the best re-entry corridor in case of emergency. In this case, the methodology suggested in Fusaro et al 17 could be exploited. It is worth to notice that this should be theoretically assessed for each point of the mission or at least for the critical point of each mission phase.…”

The paper deals with the conceptual design and sizing of a cabin escape system to be applied to a trans-atmospheric transportation system. At first, the role of suborbital vehicles towards the development of a hypersonic transportation system is presented. From this analysis, it has been clear that one of the key points in enhancing the public consensus is to demonstrate a higher level of safety and reliability with respect to the current space vehicles. Since the time of the Space Shuttle enterprise, the development of a proper escape system has been considered crucial to diminish the risk of loss of lives per mission, moving from space-like reliability characteristics to values closer to the aeronautical case. In particular, this paper presents the conceptual design of an escape system for a single stage vehicle aimed at parabolic flights. The proposed design methodology starts with the identification of the major requirements that will lead the design and sizing activities. Then, special attention is devoted to the identification of the required capabilities of a Cabin Escape System and to the selection of the proper subsystems able to guarantee these functionalities. Indeed, considering the high-level of complexity of such a system, during the design process, specific attention should be paid to the impact of on-board systems integration on the overall transportation system architecture and layout. At this purpose, a proper utilization of CAD models can ease the integration process allowing fast verification of mass and volume budgets as well as integrated simulation techniques could be useful. Furthermore, the possibility of exploiting this system during the different phases of the mission should be properly evaluated and, eventually, a preliminary impact risk analysis is reported.

“…These innovative vehicles will be characterized by a very high level of complexity that forces the designers to find innovative design methodologies aimed at reducing the risk associated to wrong high level design choices and allowing money and time saving. In this context, this paper suggests an innovative methodology based on a Model Based Systems Engineering (MBSE) [1] [2] approach to support Mission Analysis activities, i.e. all those complex design activities aimed at providing the engineers with the mission baseline as starting point for vehicle design, beginning with stakeholders' needs and high level strategic decisions analyses.…”
