Simcenter Amesim – 0D/1D Dynamic System Simulation

The Simcenter Amesim solutions for aerospace systems enable you to ensure a safer and more reliable design of physical systems while shortening time-to-market.

Using validated, parametric models that are already available in Simcenter Amesim, it's easy to quickly reppresent the systems of the aircraft, rotorcraft, or UAV, and predictively simulate their dynamic behavior, testing various mission profiles or critical working cycles. Simcenter Amesim supports engineering decision making, from functional requirement definition up to detailed design.

Applications

diminiure i costi e il time to market
ACTUATION and FLIGHT CONTROLS
Simcenter Amesim supports the design and optimization of high-lift device actuation systems with an unparalleled multi-domain system simulation approach, that easily handles the combination of hydraulics, 2D mechanics and electrics in a unique modeling environment. The user can swiftly explore several design solutions, switching components and layouts, and assess the behaviour of highly dynamic components (such as nozzle flapper flow control servo valves, pressure valves and any kind of piloted fluid component) and the system’s functional performance attributes (multibody, stress and durability) in a common environment.

HYDRAULIC SYSTEMS and LANDING GEAR
Simcenter Amesim provides tools to assess the whole landing gear and hydraulic power system performance. The user can analyze a design’s behaviour throughout all the required functionalities: landing, extension and retraction, including braking and steering.
Simcenter Amesim supports the multi-domain nature of the task, as it includes capabilities to model hydraulics, electrics and thermal systems and takes into account system structure/actuator coupling. Simcenter Amesim is a valid support to addresses the challenges posed by physical tests and maintenance costs reduction, sophisticated technologies and materials, as well as safety and certification requirement.

ENVIRONMENTAL CONTROL SYSTEM (ECS)
Design the optimal environmental control system that makes air breathable and comfortable in terms of pressure, temperature, flow and humidity.
Simcenter Amesim contains pre-validated models to reproduce complex systems dealing with gas dynamic, thermal pneumatics, vapor cycle (two-phase flow), air conditioning, controls... and assess their performance over different working cycles, mission profiles, and failure conditions, all in one modeling environment. Assess transient behaviour of your design early in the product development cycle, or carry out in-depth virtual analysis to improve and optimize behaviour of your current design.

ENGINE and ENGINE EQUIPMENT
Predictively assess the dynamic behaviour of any kind of jet engine and get an initial evaluation of engine performance. The impact of aircraft mission requirements in terms of thrust and available power – and therefore fuel consumption – can be assessed by accounting for the complete aircraft systems and mission.
Simcenter Amesim supports the design and engineering of fuel systems and their controls, as well as engine control actuators. The solution helps you design market specific, pressure-feed fluid systems in aircraft engines, and build reliable thermal-hydraulic systems.

FUEL SYSTEMS
Simcenter Amesim helps you design the complete aircraft fuel system, incorporating pressure, temperature, flow transfer and ullage composition tracking. Application areas include the thermal behaviour of the fuel system.
Using a scalable approach, the solution allows you to manage multidisciplinary systems for advanced aerospace fuel system design: fuel pressurization, fuelling, refuelling and defueling of tanks with complex shapes, accounting for the aircraft attitude and acceleration, venting, on-board inert gas generation system (OBIGGS)
fuel distribution networks, overall energy management.

ELECTRICAL SYSTEMS
Design the electrical systems of any aircraft, building your sketch with the pre-validated models available inside Simcenter Amesim (electric motors and drives, electromechanical, electric basics and converters, and aircraft electrics).
Simcenter Amesim helps you succeed in facing the new challenges of the “more electric aircraft.” With an energy balance approach to modelling, it ensures you can analyze the electrical systems and their components in complex networks, as well as account for the thermal integration within the complete aircraft from the very beginning of the design process.
