Aerospace System Simulation Solutions

Design and rate actuation systems using hydraulic, pneumatic, and electro-mechanical technology. Predict trade-offs and transient response in isolation or integrate with controls and the power supply network. Use actuators for braking or flight control surfaces, hydraulic and pneumatic mechanisms in landing gear dampers, and devise landing gear kinematics. Consider different cylinders, orifices, valves, lines, bogies, tires, and struts. 

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. 

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 a 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. 

Develop and analyze propulsion architectures for zero-emission aircraft leveraging onboard hydrogen storage and fuel cells. Compute their performance and transient behavior as individual components, or combine them with heat management, electric drives, and controls for integrated studies. Consider cryogenic and gaseous tanks, hydrogen evaporators, humidifiers, stacks, ducted fans or propellers, and hybrids including gas turbine hydrogen combustion.
