“…These models are integrated into a generic, high-performance aircraft model created as part of the Air Force Research Laboratory's INVENT program and briefly described above. Further details can be found in Brodie et al 14 and Gvozdich 12 .…”

“…The high-performance aircraft model, as detailed in Bodie et al 14 , is comprised of six subsystems: the propulsion subsystem (PS), avionics subsystem (AVS), adaptive power and thermal management subsystem (APTMS), fuel thermal management subsystem (FTMS), high-performance electric actuation subsystem (HPEAS), and robust electrical power subsystem (REPS). Bodie et al also presents the necessary flow of mechanical (i.e., force and position), thermal (i.e., mass flow rates, fluid temperatures, fluid pressures, and heat loads), and electrical (i.e., currents and voltages) information exchanged between these coupled subsystems.…”

As energy requirements continue to grow for high-performance vehicles, power and thermal demands necessitate the conscientious organization, integration, and design of an aircraft to mitigate excess heat generation. Driving energy demands, emerging and maturing technologies, such as directed energy weapons and high-energy sensors, introduce substantial loads onto an aircraft. Examples of the former under research and development for military applications include particle beams, microwaves, and lasers. These devices offer a versatile suite of operational modes for offensive and defensive, lethal and non-lethal applications. Although promising, they present integration challenges, primarily regarding thermal management. Directed energy weapons operate at low efficiencies, generating large thermal loads over very short intervals that can quickly overwhelm a traditional thermal management scheme. In addition, they must operate at particular conditions, which introduce additional constraints. Results for the power and thermal demands that a directed energy weapon subsystem (DEWS) introduces into a high-performance aircraft are presented in this paper as is a discussion of how to appropriately manage the system-level impacts which result. NomenclatureAPTMS = adaptive power thermal management subsystem AVS = avionics subsystem DEWS = directed energy weapon subsystem FTMS = fuel thermal management subsystem HPEAS = high-performance electric actuation subsystem PS = propulsion subsystem REPS = robust electrical power subsystem SSL = solid-state laser TES = thermal energy storage TMS = thermal management subsystem

“…To obtain dynamic balance / margin, INVENT is currently investigating all of these techniques in conjunction with the thermal balance to determine the overall aircraft-level impacts of the candidate architectures and technologies. Descriptions of some of these initial studies along with the simulation tools being utilized are provided in [9,10,3].…”

“…Besides, the aerodynamic shape and high stealth of the modern advantage aircraft also make it even more difficult to obtain ambient heat sinks, resulting in a serious decrease in their cooling ability [4]. The decrease in ambient heat sinks' cooling ability will cause an increasing dependence on the fuel heat sink [5]. However, the cooling capability of fuel is restrictively limited by its residual mass in tank, which will become very scarce in the later stages of the flight period because of the constant consumption of fuel.…”

The aerospace-based heat sink is defined as a substance used for dissipating heat generated by onboard heat loads. They are becoming increasingly scarce in the thermal management system (TMS) of advanced aircraft, especially for supersonic aircraft. In the modern aircraft there are many types of heat sinks whose cooling abilities and performance penalties are usually obviously different from each other. Besides, the cooling ability and performance penalty of a single heat sink is even different under different flight conditions—flight altitude, Mach number, etc. In this study, the typical heat sinks which are the fuel mass, ram air, engine fan air, skin heat exchanger, and expendable heat sink will be studied. Their cooling abilities/capacities, and exergy penalties under different flight conditions have been systematically estimated and compared with each other. The exergy penalty presented in this paper refers to the exergy loss of aircraft caused by the extra weight, drag and energy extraction of various heat sinks. The estimation models, as well as the results and discussion have been elaborated in this paper, which can be can be used to further optimize the TMS of modern advanced aircraft, for example, the layout design of various heat sinks and the improvement the control algorithm.
