“…Vascular-enabled, actively-cooled composites can provide lightweight structural performance and removal of excess heat in thermally demanding applications, particularly those in which FRP materials have been traditionally excluded due to lower thermal stability of the polymer matrix compared to metallic or ceramic counterparts. Some modern applications we envision for active-cooling in composites include highpower antennas [105,106] and laser diode arrays, [107] hypersonic aircraft, [108,109] protective casings for fuel cells, [110,111] and electric vehicle battery packaging. [112,113] To demonstrate the ability of our serpentine vasculature for regulating temperature and better understand governing physics, we began with a series of experiments via active pumping of liquid coolant (i.e., distilled water) under a constant heat flux.…”

Nearly all‐natural and synthetic composites derive their characteristic attributes from a hierarchical makeup. Engineered metamaterials exhibit properties not existing in natural composites by precise patterning, often periodically on size scales smaller than the wavelength of the phenomenon they influence. Lightweight fiber‐reinforced polymer composites, comprising stiff/strong fibers embedded within a continuous matrix, offer a superior structural platform for micro‐architectured metamaterials. The emergence of microvascular fiber‐composites, originally conceived for bioinspired self‐healing via microchannels filled with functional fluids, provides a unique pathway for dynamic reconfigurable behavior. Demonstrated here is the new ability to modulate both electromagnetic and thermal responses within a single structural composite by fluid substitution within a serpentine vasculature. Liquid metal infiltration of varying density micro‐channels alters polarized radio‐frequency wave reflection, while water circulation through the same vasculature enables active‐cooling. This latest approach to control bulk property plurality by widespread vascularization exhibits minimal impact on structural performance. Detailed experimental/computational studies, presented in this paper, unravel the effects of micro‐vascular topology on macro‐mechanical behavior. The results, spanning multiple physics, provide a new benchmark for future design optimization and real‐world application of multifunctional and adaptive microvascular composite metamaterials.

“…Thermal protection is one of the key challenges in the application of scramjet engines [1]. Among the available cooling methods, the active regenerative cooling using endothermic hydrocarbon fuel as coolant is recommended as the most effective way for its high efficiency and low performance loss [2][3][4][5][6].…”

Thermal protection is still one of the key challenges for successful scramjet operations. In this study, the three-dimensional coupled heat transfer between high-temperature gas and regenerative cooling panel with kerosene of supercritical pressure flowing in the cooling channels was numerically investigated to reveal the fundamental characteristics of regenerative cooling as well as its influencing factors. The SST k-ω turbulence model with low-Reynolds-number correction provided by the pressure-based solver of Fluent 19.2 is adopted for simulation. It was found that the heat flux of the gas heated surface is in the order of 106 W/m2, and it declines along the flow direction of gas due to the development of boundary layer. Compared with cocurrent flow, the temperature peak of the gas heated surface in counter flow is much higher. The temperature and heat flux of the gas heated surface both rises with the static pressure and total temperature of gas. The heat flux of the gas heated surface increases with the mass flow rate of kerosene, and it hardly changes with the pressure of kerosene. Results herein could help to understand the real heat transfer process of regenerative cooling and guide the design of thermal protection systems.

“…Помимо самостоятельного использования активного охлаждения в системах тепловой защиты гиперзвуковых самолетов, возможна также его интеграция с пассивными теплозащитными покрытиями. В работе [22] приведены результаты исследования совместного применения активного охлаждения и пассивной теплозащиты для самолета-разгонщика АКС с максимальным числом Маха М = 8 на высоте 60 км. Аналитические расчеты и математическое моделирование показали, что активная теплозащита с магистралями охлаждающего топлива способна снизить массу теплозащитных покрытий на 40 % от базовой (температура поверхности под ТЗП 330 К).…”

On the basis of analytical and experimental data, this paper presents possible levels of thermal loading of reusable hypersonic aircrafts. Methods for ensuring the thermal regime of such aircrafts using various passive and active thermal protection technologies are considered. The conducted analysis of the scientific and technical background in terms of the practical implementation of these technologies allowed the authors to draw the conclusion about the relevance and expediency of creating an integrated thermal protection system for reusable high-speed aircrafts.
