4.3 Final Motor Specifications
Although final motor specifications are inherently dependent on gearbox ratio selection, the
calculations performed in Section 5 dictate the systems overall speed and torque requirements.

4.4 Parametric Model Development
To perform a finite element analysis and derive the necessary torque
equations, an accurate model of the simulator base was created. A
parametric model was developed in Solidworks by replicating every
component in the base critical to the structure as separate files. Each
part was measured using calipers with tolerances of ±.001 in. These
files were mated and given relations in an assembly drawing so valid
point-to-point dimensions could be found. The accuracy of the upper
scissor arms and spring measurements were imperative to the
model’s success as those parts mate to the new lower scissor arms.
The upper scissor arm model was exported into ABAQUS to
perform the finite element analysis.
4.5 Prepar3D Compatibility
Prepar3D is a flight simulation software developed
by Lockheed Martin. Future design teams will work
to integrate the simulator with a license of Prepar3D
Academic v 1.4.4747.0. It is used for both
entertainment and training purposes. The user is
provided with an immersive cockpit experience and
is able to load real-life airports and environments.
There is also a custom mission design option.
Software development can be done using the SimConnect Developer SDK. Software add-ons are
flexible and can be written in C, C++ C#.net or VB.net. Developers are free to add gauge
processing, replace events, record and monitor flights, create custom missions, manipulate the
weather, enable hardware with Prepar3D and control additional views and/or AI aircraft. The key
to communicating with the simulator hardware is the development of a custom client which
communicates with the Prepar3D software in run time. This can be done by modifying source
code and was outside the scope of Phase II.
