Thermal management is concerned with the dissipation of excess heat through refrigeration cycles and the heating of select sub-systems. Refrigeration or cooling cycles are typically ranging from light air cycles (“environmental control systems”) to highly energy-efficient vapor cycles. The cooling is then provided directly from the refrigerant to the heat source, or indirectly via a liquid cooling system. Heat is typically dissipated to ram air via dedicated channels, or secondary fluids such as hydraulics or fuel. The fuel system itself consists of the aircraft tanks and distribution and venting networks. This application offers the different heat exchanger, compressor, turbine, pump and ejector models for sub-system and integrated system models and suitable refrigerant and coolant models.
This application focuses on the physical domain of thermal management and fuel, and is therefore applicable to additional broader advancements such as hydrogen powered aircraft and hybrid electric propulsion.
A vapor cycle consists of at least one evaporator and a condenser plus compressors and expansion devices
The aircraft fuel system consists of fuel tanks, a pipe network with pumps and ejectors, and auxiliary systems for ventilation and inerting.
An aircraft environmental control system (also called air generation unit or air cycle) consists of turbomachinery and heat exchangers
Pneumatic systems are used to supply pressurized air from the APU or via the engine bleed air system as well as for the anti-ice systems, often including the actuation of valve
Size and evaluate on- and off-design performance in both commercial and military applications. Analyze cycle performance and dynamics in different configurations, like turbojets, turbofans, and turboprops. Construct and assess secondary power networks delivering pneumatic, hydraulic, and electrical power. Integrate auxiliary power units, fuel cells, and emergency power for continuous operation of essential aircraft functions. Jet engines as the prime mover of aircraft have evolved from piston engines to gas turbine engines to the emerging hybrid-electric engine and the latest hydrogen powered engines. The gas turbine engine consists of major sub-systems such as compressors, turbines, burners, mixers, etc. Given the latest trend and research happening in the field of hydrogen powered aircraft, it is of prime importance to study each of these sub-systems to effectively understand the thrust-weight ratio, efficiencies, cost, etc.
The engine is also used as a secondary power source and it is critical to study the engine performance with the full aircraft system. The Jet Propulsion library provides the foundation to model any gas turbine engine be it commercial or military. The off-the-shelf template configurations allow users to quickly assemble all the sub-systems of their need to construct the engine model. The cross-library features enable the library to be connected to Aircraft Dynamic Library.
The gas turbine engines used in commercial and military applications are classified into turbojet, turbofan, and turboprop
Size and analyze fixed-wing aircraft. Compute trade-offs between masses, engine ratings, climb rate, endurance as well as range, and evaluate alternatives for optimal choices. Leverage aircraft models as platform for synthesizing and assessing aircraft sub-systems. As meaningful, expand from three-degrees of freedom models investigating full mission profiles to high fidelity six-degrees of freedom aircraft covering complete flight dynamics.
Build and evaluate propulsion systems ranging from fully electric concepts to hybrids combining electric power and gas turbine. Study the power train dynamics and sizing trade-offs by themselves, or integrate with thermal management, aircraft sizing and performance, or propeller/fan-based thrust generation. Consider different batteries, electric machines, inverters, breakers, ducted fans or propellers, turbofan, and turboprop cycles.
