“…However, the response time of the heat transfer is slower than the power generation. Stoia et al [66] designed an IPTMS for highspeed aircraft based on the Brayton cycle, using sCO 2 (supercritical carbon dioxide) as the coolant. This IPTMS can be recuperated (with the use of a recuperator) or non-recuperated.…”

Projects related to green aviation designed to achieve fuel savings and emission reductions are increasingly being established in response to growing concerns over climate change. Within the aviation industry, there is a growing trend towards the electrification of aircraft, with more-electric aircraft (MEA) and all-electric aircraft (AEA) being proposed. However, increasing electrification causes challenges with conventional thermal management system (TMS) and power management system (PMS) designs in aircraft. As a result, the integrated power and thermal management system (IPTMS) has been developed for energy-optimised aircraft projects. This review paper aims to review recent IPTMS progress and explore potential design solutions for civil aircraft. Firstly, the paper reviews the IPTMS in electrified propulsion aircraft (EPA), presenting the architectures and challenges of the propulsion systems, the TMS cooling strategies, and the power management optimisation. Then, several research topics in IPTMS are reviewed in detail: architecture design, power management optimisation, modelling, and analysis method development. Through the review of state-of-the-art IPTMS research, the challenges and future opportunities and requirements of IPTMS design are discussed. Based on the discussions, two potential solutions for IPTMS to address the challenges of civil EPA are proposed, including the combination of architecture design and power management optimisation and the combination of modelling and analysis methods.

“…The recuperation depends on the ratio of heat transport to power required of the IPTMS. The IPTMS in [66] is recuperated and can provide power density greater than 3 kWe/L with up to 35% energy conversion efficiency. However, because of the recuperator, the weight and the volume of the IPTMS are significantly increased.…”

“…Brayton thermodynamic cycles are anticipated for an integrated power and thermal management system on high-speed aircraft, which would also require a highperformance recuperator, or heat exchanger, to effectively increase energy conversion efficiency. [1,2] However, the current state of thermal management capability, whether for terrestrial and airborne power systems, is largely driven by ultrahigh performance metallic materials capable of operation in extreme environments. Components in the thermal management system of a terrestrial or airborne grid are subject to particularly harsh environments, wherein thermal stresses and the immediate atmosphere place incredible demand on the materials of construction.…”

The effect of aluminum and tantalum concentrations on a refractory metal complex concentrated alloy is reported, particularly with respect to their effect on microstructure and phase composition of the alloy in cast and annealed form. Alloys with an equiatomic composition, (AlCrMoTaTi), an aluminum‐lean composition (Al0.75CrMoTaTi), and a tantalum‐lean composition (AlCrMoTa0.75Ti) are produced via arc melting. The alloys exhibit multiphase structures, confirmed by X‐ray diffraction, microstructural characterization, and thermal analysis. The minor off‐equiatomic adjustments of aluminum and tantalum in this alloy system did not drastically alter the prevalence of the Cr–Ta‐based Laves phase. Correlations between thermodynamic predictions and observed phase transformations via thermal analysis are improved upon refinement of calculations removing impractical intermediate phases. Experimental findings provide information for the refinement of thermodynamic modeling and deliver additional insight into the optimization of alloy compositions within this five‐component system.

“…

The pursuit of high-speed flight presents critical challenges in the areas of thermal management, power generation, and vehicle performance and efficiency. Sophisticated concepts for airborne thermal management systems have been proposed [1] and are proposed for both airborne and terrestrial power generation systems. [2] Momentum in the development of novel technologies for high-speed flight is particularly demanding of current state-ofthe-art materials, and, therefore, warrants significant effort in the maturation of novel alloying concepts for extreme environments.

Herein, the development of refractory complex concentrated alloys in the Al–Cr–Mo–Ta–Ti alloy system is reported. Alloys with modified Al and Ta concentrations are designed using CALPHAD tools and produced via arc melting and characterized in both as‐cast and annealed forms. Properties of the alloys, nature of the microstructures, and phase transformation behavior are described via X‐ray diffraction, microstructural characterization, microhardness, and differential scanning calorimetry. Two alloys, namely, Al0.25CrMoTa0.8Ti and Al0.75CrMoTa0.8Ti, are represented by a body‐centered‐cubic matrix phase after annealing, along with a secondary Cr–Ta Laves phase of the C15 and C14 polytypes, respectively. In as‐cast and annealed forms, the Al0.75CrMoTa0.45Ti alloy comprises a single‐bcc phase. Microhardness of the Laves phase containing alloys demonstrates susceptibility to cracking, whereas the Al0.75CrMoTa0.45Ti alloy displays high specific hardness, signs of ductility as evidenced by slip traces near indentations, and minimal scatter of hardness values.
