Hello, I am Alberto Soto with Siemens Digital Industries Software.
Today, I am going to show how easily you can model the 3D tank of an aircraft fuel system:
and take the aircraft’s altitude and acceleration into account.
For this, we will start from a tank CAD and use the Simcenter Amesim CAD import plugin for fuel systems.
The plugin for fuel systems will support your engineering activities and decision making for:
refueling, fuel metering, tank cascading, center of gravity management,
thermal studies or impact on flight dynamics.
For example, here you can see refueling and transfer between three bays.
The first step consists in generating the geometrical data of the complex shaped tank based on a CAD part.
This is done thanks to the CAD import functionality,
located in the Tools section of Simcenter Amesim.
Start by importing a CAD part corresponding to the fluid in the tank.
You can also import the tank structure and extract the fluid volume of interest.
Here, we launch the fuel system plugin.
First, we select the body we want to map.
Then, we define the range of effective attitudes,
defining the flight envelope we want to cover.
We choose whether we want to extract the liquid inertia tensor,
for example, if we want to study the impact of the fuel inertia on flight dynamics.
We select the tank walls for which we want to extract wet areas:
these can be used to assess thermal exchanges between the fuel and the structure.
Now, everything is ready to launch the tank data extraction.
We can repeat this operation for all the tanks in our system.
We can also generate geometrical data to model complex orifice shapes,
such as ribs between the tanks.
When we launch the extraction, different information is obtained,
such as the height of fuel, center of gravity, wet areas and fluid inertia tensor.
Once the extraction is finished, you can use the generated files in Simcenter Amesim,
to parameterize the aircraft fuel system 3D tank and rib models.
You can then model complex scenarios, including:
fuel transfer between tanks, aircraft orientation and acceleration impact on system performance.
In the demo section for the Aircraft Fuel System library,
you can find several examples of how to use the 3D tank.
In addition, the demos for the Aircraft Fuel System solution depict more advanced examples.
You can use these examples as starters to study refueling scenarios,
center of gravity management, thermal assessment or coupling with flight dynamics.
To sum up, we have shown how, in a few clicks, you can accurately model fuel system tanks and rib orifices,
based on a CAD, by using Simcenter Amesim.
