Computer
Modeling
eAc's design team uses a variety of computer modeling
software packages to generate the best possible
end product. The integration of rocket propulsion
simulation programs and mechanical design software
has proven to be very functional. Optimized motor
performance parameters can be translated into the
corresponding motor geometries. Pep-code, flight
simulation, burn-rate analysis, and 6DOF software
codes allow for the complete pre-fire analysis of
all ground and flight-testing. Using CAD software,
eAc design engineers generate detailed computer
models of very complex components of hybrid propulsion
systems such as oxidizer valves and injectors. Having
the entire propulsion system in CAD format allows
us to accurately predict important aerodynamic parameters
such as component weights and the overall center
of gravity for the system. eAc's ability to work
with many different CAD software packages provides
an excellent avenue for technical communication
with the customer and allows effortless integration
of any mechanical components provided by sub-contractors
or customers. We also have the CAM capabilities
that allow us to communicate with our CNC milling
machine to generate complex prototypes and end product.
In order to provide safe lightweight designs, all
critical components are carefully studied using
FEA software. The use of Finite Element Analysis
(FEA) software brings a high level of confidence
to any product delivered to the customer. Our design
team is able to simulate any environment in which
our components will be exposed to and in turn prevent
any failure due to any excessive thermal, structural,
or vibrational loads.
