+                    This year, our payload consists of two main experiments: Quantifying the
+                    vibrations experienced in flight from the movement of the rocket, and
+                    testing the ability of a peristaltic IV pump to produce and maintain
+                    laminar flow while experiencing high levels of acceleration. The vibration
+                    experiment contains a mechanical component consisting of plates of different,
+                    commonly used materials and thicknesses. These plates will have holes drilled
+                    into them and be tapped for different screw sizes. We will fly one of these
+                    assemblies and keep one on the ground at competition to compare how the
+                    vibrations affect our screws. There is also an electrical PCB being flown that
+                    will have a 3-axis accelerometer on it, which will provide a profile of the
+                    vibrations felt by the screws on the rocket. For the peristaltic pump
+                    experiment, we will be flying a student researched and developed peristaltic
+                    pump. We will use this to monitor the Reynold&apos;s number of a water and
+                    glycerol solution, tracking the ability of the pump to produce laminar flow.
+                    To do this monitoring, we will employ the use of electrical sensors such as
+                    flowmeters to track flow velocity and thermistors to extrapolate the density
+                    and viscosity of the solution as the flight of the rocket progresses.

+                      Airbrakes: The airbrakes are a trio of metal panels which slide out
+                      from the upper body tube during flight in order to change the drag
+                      force acting on the rocket. This allows us to actively control the
+                      final apogee of the rocket and allow us to hit our target more
+                      precisely. An internal servo drives a rotating cam mechanism that

+                      computation for the airbrakes system. It uses a powerful 32 bit processor to
+                      read in data from our onboard IMU and other sensors, generate state estimates,
+                      and generate control commands for the airbrakes servo. It also has significant
