“…The oil acquires waste heat due to soakage from the engine casing and bearings (but also from gearboxes, the constant speed drive, pumps, electrical generators, and so forth) and then rejects it to an appropriate sink. The sinks are normally fuel, using a fuel-oil heat exchanger (FOHE -also called the fuel-cooled oil cooler, or FCOC), or air, by means of an air-oil heat exchanger (AOHE -also called air-cooled oil cooler, or ACOC) [38]- [41].…”

“…Fuel that is heated outside the tanks and not immediately employed for combustion can be recirculated back to the tanks [8], [38], [128]. By doing this, the large 'thermal inertia' of the fuel in the tanks can be exploited (although this inertia reduces as fuel is consumed).…”

“…From research regarding TMS design and analysis at early design phase, it is discovered that the TMS architecting and analysis always start from the identification of the major heating and cooling loads in the aircraft.

The aircraft thermal management system functions to provide suitable working conditions for pilot, crew, passengers, and the other aircraft systems. The additional weight, drag and power consumption caused by it greatly influences the performance of the aircraft. However, due to rising heat load of emerging novel aircraft concepts, traditional design approaches which rely on data and empirical equations may not apply to the future thermal management systems. Many existing literature which tried to identify the optimal thermal management system architectures only considered limited architecture space where the candidates were pre-selected in terms of experience or intuition. Therefore, viable but non-intuitive architectures may not be included in the design space. To fill this gap, this paper proposes a behavior-based backtracking methodology to systematically populate the architecture space by enumerating both intuitive and non-intuitive architectures. Thermal management requirements for traditional and novel configurations are used to generate the architectures. By comparing the generated architectures with existing ones, this paper validates that the proposed methodology is capable of generating both intuitive and non-intuitive architectures.

“…Fields of importance for those kinds of applications are in general components of high power density, systems with temperature sensitive materials (such as kerosene fuel, semiconductor material, aluminium) and temperature-dependent material properties (such as hydraulic liquids). Aviation-related examples are the fuel system [Gavel, 2007], the hydraulic actuation system [Behr et al, 2013], the ECS [II] or the Thermal Management System (TMS) [Seki et al, 2015] of an aircraft.…”

Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required in, nowadays complex, system design. The challenge during this early design phase is the use of higher-fidelity methods typically applied in later development stages. Integration of models and simulations to enhance analysis capability while maintaining a streamlined, transparent, and low cost (low effort regarding task time and workforce) work process is therefore required.In this thesis, the use of object-oriented KBE methods to enable an early integration of simulation models, based on incomplete data, is presented. Before this, careful investigations of modelling and simulation approaches of multi-domain systems are carried out, and their use in the ACD phase is examined regarding the efficiency between effort and result accuracy. A central, parametric information model approach to make this possible is presented. By the means of the extended use of XML, XSD and XSLT, domain-specific architectural models can be translated from this dataset, supporting a direct CAD domain integration and automated model creation.Modelling systems as graph networks is a simple approach for unified modelling in the conceptual design stage. Based on this theory, the similarity of different modelling approaches like Dependency Structure Matrix (DSM), MDDSM, or Channel-Agency Networks is shown. Using object-oriented programming, all these and more aspects such as e.g. Fault Tree Analysis (FTA) can be handled globally as one graph set.Based on the outcomes of the theoretical part, the development of a conceptual aircraft design framework is described. Backed by a central XML-based namespace, this framework integrates a complete CAD environment to ensure an appropriate environment for the geometric domain modelling. In addition, the use of KBE for automated simulation i model integration is exemplified by a hydraulic aircraft flight control system (FCS) simulation model. In conclusion, an example of multiaspect modelling using object-oriented handling of a graph network is shown. For future scenarios, unified modelling and semantic approaches are mentioned. ii Populärvetenskaplig SammanfattningMed nya, mer komplexa och mer integrerade flygplansgrundsystem står konceptutvärderingsfasen (ACD) inför nya utmaningar. Multidisciplinärt, anpassningsförmåga, konstruktionsautomation, förbättrad analysnoggrannhet och modellbaserad integrerad utveckling (MBSE) är några nyckelord. I denna avhandling diskuterats användning av objektorienterade Knowledge Based Engineering-(KBE) metoder i konceptutvärder-ingsfasen som möjliggör en tidig integration av simuleringsmodeller baserade på ofullständiga designuppgifter. Denna integration av modeller och simulering ska leda till en ökad analyskapacitet och samtidigt bibehålla en strömlinjeformad, transparent och snabbt arbetsprocess.I avhandlingens teoretiska del behandlas universella modelleringsmetoder (som DSM och Channel-Agency Nätverk) och simuleringsstrategier. Dessutom analyseras och bes...
