<h2 class="display-4">About LANDER</h2>
|
||
<p>
|
||
As interest in colonizing the Moon increases, developing a
|
||
sustainable method of transporting equipment and resources to
|
||
and from the lunar surface will be necessary. LANDER's
|
||
approach to this problem is a system that uses one thruster
|
||
capable of vectoring thrust to control vehicle attitude and
|
||
perform propulsive landings with minimal fuel use. However,
|
||
key to the design challenge is creating a suitable test
|
||
environment for such a system that can simulate variables,
|
||
such as lunar gravity and a lack of atmosphere. Project LANDER
|
||
endeavored to provide a potential solution by designing a
|
||
complex simulation utilizing live data. Due to an abbreviated
|
||
timetable and low-quality components, LANDER did not meet all
|
||
of its requirements for the Thrust Vector Control Test and
|
||
Operational Demonstration. However, while LANDER was a
|
||
proof–of-concept system, the team hopes to lay the foundation
|
||
for future development in this area.

|

<p>
|
||
The fully assembled system and the CAD of the system can be
|
||
seen on the figure to the right. LANDER consists of 5
|
||
subsystems, Control Software, Avionics, Control Mechanisms,
|
||
Structure, and Test Stand. These subsysems all come together
|
||
to produce a test stand capable of simulating a vehicle
|
||
landing on the lunar surface. The test stand involves a
|
||
complex hardware in the loop computer simulation running on a
|
||
microcontroller.

<h2 class="display-4">Software Concept of Operations</h2>
|
||
<p>
|
||
The simulated vehicle comprises a feedback loop where the
|
||
rocket motor causing forces on load cells translates to forces
|
||
in the simulation. The control system utilizes a PID which
|
||
gives commands to the simulated vehicle; the commands are then
|
||
translated back into hardware as TVC commands. The physical
|
||
vehicle encompasses the avionics, TVC, and load cells. The
|
||
physical vehicle receives commands from the simulated vehicle
|
||
and returns, calculated thrust data back to the control
|
||
software.

The experimental thrust curve shows that the four load cells
|
||
managed to match the thrust curve for the
|
||

||
>Estes F15</a

||

|
||
within 6.2 Newton Seconds or 13.2% of expected. Due to
|
||
multiple changes in project and scope LANDER initially chose
|
||
very cheap load cells since the test stand demonstration was
|
||
originally mean't to be a verification for much larger goals.
|
||
Acquiring usable data from the load cells ended up taking much
|
||
more time and resources than the team initially expected, but
|
||
thanks to proper risk mitigation the team was able to overcome
|
||
the challenge and find a real solution.
