The chapter will present several considerations and hypotheses about R.A.M.S. characteristics and logistic support options for operational fleets of UAS. First, a short review will outline how logistic support is relevant for UAS in comparison with other complex systems. It focuses on how logistic support must be designed and how such a design must be driven up jointly with the system design. The relevance of the scenario in defining logistic support will be discussed. Next is a consideration of how reliability, safety, and maintainability are relevant aspects for all advanced systems, in particular for UAS, explaining how these characteristics can be achieved by design. The maintenance program will always be defined in the design phase and, consequently, the logistic support will also be defined. Several tools useful for these purposes will be presented and shortly described. Some synthetic considerations will be presented regarding transportability, a characteristic strictly connected to safety, reliability, maintainability, and logistic operations, also of particular relevance for UAS. Other peculiarities of UASs, mainly deriving from the flight segment and ground segment coexistence, will be presented. Having in mind the targets, requirements, and constraints at the origin of a fleet of UAS, in addition to the technical features of the UAS, the fleet sizing and the related system support (elements and strategies) definition is a very complex problem. A useful tool to face this is the stochastic simulation, in particular Monte Carlo methodology. A possible feature of a UAS fleet simulation model is presented and discussed.

The need for a greener and competitive aircraft is leading to the use of new technologies. A thorough assessment of these technologies is mandatory from the initial phases of aircraft design to understand their feasibility and to select the most promising one both in terms of performances and in terms of costs. This paper proposes a methodology to assess the operating cost of innovative technologies for regional aircraft. In particular, two NASA studies have been adopted to determine the impact onto costs of MEA and AEA technologies and advanced ECS solutions for two innovative regional aircraft concepts developed during the European Clean Sky 2 research. The proposed methodology is able to assess the effect of on-board systems electrification level in terms of fuel and maintenance costs savings. The methodology, which allows to evaluate the effect of specific technological improvements onto costs, is applied exploiting the results provided by a reliable cost model and gives the opportunity to quantify operating cost savings for different regional aircraft. Applying the modified cost model to the reference aircraft under study, savings ranging from 1.6 to 3.1% of direct operating cost are estimated for MEA and AEA technologies. Greater savings are estimated for the individual cost items involved. More specifically, a reduction of fuel cost ranging from 6 to 14.5% is envisaged as a consequence of the lower SFC associated to innovative ECS technologies.

The aircraft design is a collaborative and multidisciplinary process. It involves several experts with different disciplinary competences. These disciplinary experts often belong to different departments or organizations. The EU funded H2020 AGILE project aims at developing new generation of Multidisciplinary Design Analysis and Optimization (MDAO) frameworks. In particular, the AGILE project tackles the investigation and the development of technologies able to enhance the collaboration between the disciplinary experts. The present paper deals with a MDAO framework developed in the context of the AGILE research project. The integration of some disciplinary expertise is described by means of a case study of an innovative regional aircraft. Some disciplinary design variables are investigated to verify the correctness of disciplines integration and to quantify the mutual dependences among the design disciplines. In particular, the variation of the engine By Pass Ratio and the electrification level of the On-Board Systems are investigated through the MDAO workflow developed for aircraft preliminary design. Finally, the results show a plausible interaction among the disciplines and interesting trends regarding aircraft systems electrification.

This paper deals with the study of the power matching of the propulsion system and on-board systems changing the on-board systems’ electrification level. In particular, four system architectures have been studied, each one with a different level of electrification starting from the More Electric Aircraft (MEA) to the All Electric Aircraft (AEA) systems. The mass and the power requirement of each system architectures have been analysed together with the change in engine specific fuel consumption. Then, these results have been used to quantify the influences of engine and systems power matching to the entire aircraft. In particular, the beneficial effect of system electrification has been evaluated as an increment of aircraft range. Moreover, two reference aircraft – a regional jet and a short/medium range liner – have been selected to understand the variance of the power matching changing aircraft dimensions and mission range. The study is carried out using a distributed and collaborative Multi-Disciplinary Design Analysis and Optimization (MDAO) environment. The results show a beneficial effect of systems electrification on systems mass and engine specific fuel consumption. At aircraft level, the results point out an increment of aircraft range up to 7.7% with a different trend for the two studied cases.

The article proposes the design of a test bench simulator to test a parallel hybrid propulsion architecture for aeronautical applications. The virtual test bench simulates, in a scaled version, the real test bench, designed for a power of about 0.4 MW. After presenting the architecture of the real propulsion system, the virtual test bench is described. The real system is basically composed by a paralleled electric motor and thermal engine which provide mechanical power to the propeller. Saving cost and volume the test bench is composed by electric motors simulates the behaviors of the real propulsion system despite their differences. The dynamic relationships expressing the transmission of torque between the components, and the method of down-sizing the power delivered are highlighted. Particular attention is given to the real inertia actions that must be simulated on the virtual test bench. An application of the proposed methodology is then presented through the simulation of the take-off phase, and the torque time histories, angular velocities and powers generated on the virtual test bench are used to verify the corresponding time histories expected in the real system.

The present work provides a method for maintenance cost estimation for a civil aircraft. The model evaluates maintenance costs at a subsystem level in order to quantify the effective impact of each aircraft part on the total maintenance cost. An analysis at the subsystem level can offer a more precise cost estimation because the most influential parameters (that is, the cost drivers) should be different for each aircraft part. Emphasis is given on the updating of a cost-estimating model proposed in 1966 that provided equations for the maintenance cost assessment at a subsystem level using the Air Transport Association nomenclature. The reference method is enhanced with additional cost items, and the choice of cost drivers is accurately considered. The application of the developed model shows good accordance with the reference values provided by the International Air Transport Association, and results are compared with the common state-of-the-art methods.

The need for a more eco-friendly and competitive aircraft are leading to innovative on-board system architectures and new way of propulsion also in the regional turboprop segment. The electrification of the aircraft seems to be an interesting approach to face these needs and to improve the overall aircraft efficiency. This paper presents some innovative concepts regarding the electrification of the aircraft on-board systems and the study of the hybrid electric propulsion for a regional twin-turboprop aircraft. In particular, the all electric architecture and an innovative use of the auxiliary power unit are discussed together with the possible advantages and new functionalities given by the hybrid electric propulsion. Finally, a preliminary mass assessment of the hybrid propulsion concept is given using a reference turboprop aircraft as test case. This proved the potentialities of this kind of propulsion but also its limit due to the present technologies. Copyright © 2018 Praise Worthy Prize - All rights reserved.

This paper explores from the electrical standpoint the enabling technologies for hybrid-electric Unmanned Aerial Vehicles (UAVs) designed for medium-altitude long-endurance mission profiles. In particular, with reference to a baseline light aircraft formerly propelled by a gasoline piston engine, different hybrid-electric architectures are compared in terms of power flow management, safety increase and overall aircraft weight reduction. For the selected hybrid solution, the discussion provides a comprehensive overview on the main features and constraints that have driven the definition of the electric system layout and the identification of the main specifications for the multiphase power converters and electric machine.

The remarkable complexity of the aircraft design is due to several reasons and one of these is certainly the high number of completely different design disciplines involved in the process. Many efforts are spent to harmonize and optimize the aircraft design trying to consider all disciplines together with the same level of detail. Within the ongoing H2020 AGILE research, an aircraft MDO (Multidisciplinary Design Optimization) process is setting up linking several design tools and, above all, competences together. This paper focuses on the evaluation of the effects of the main on-board systems design parameters on the other disciplines. Starting from a baseline aircraft (AGILE DC1 regional turbofan), the effect of each parameters have been quantified in terms of variation of aircraft weight, fuel consumption and engine performance. This analysis represents a useful starting point to better understand the importance and the influence of novel On-Board Systems configurations, such as More and All Electric, to the overall aircraft design.

In this paper, an innovative methodology for the conceptual design of hybrid-powered airplanes is proposed. In particular, this work focuses on parallel hybrid architectures, in which the thermal engine is mechanically coupled to an electric motor, both supplying propulsive power during a limited number of flight phases, e.g. during takeoff and climb. This innovative solution is the subject of several studies being carried out since the current decade. In this paper, a brief overview of the works conducted by other researchers is provided. Then, an overall aircraft design methodology is proposed, which is derived from the most renewed design algorithms. The original contribution of this work is represented by the development of a methodology for the design of hybrid propulsion systems. Moreover, the proposed method is integrated within a global aircraft design methodology. In particular, several effects of the innovative system on the entire aircraft are considered, for instance the variation of the empty mass or the impacts on fuel consumption. The paper ends with some case studies of the proposed design methodology, and a discussion of the obtained results is provided.

The aircraft design is a complex subject since several and completely different design disciplines are involved in the project. Many efforts are made to harmonize and optimize the design trying to combine all disciplines together at the same level of detail. Within the ongoing AGILE (Horizon 2020) research, an aircraft MDO (Multidisciplinary Design Optimization) process is setting up connecting several design tools and competences together. Each tool covers a different design discipline such as aerodynamics, structure, propulsion and systems. This paper focuses on the integration of the sub-system design discipline with the others in order to obtain a complete and optimized aircraft preliminary design. All design parameters used to integrate the sub-system branch with the others are discussed as for their redefinition within the different detail level of the design.

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.
