+# Launch of LV2c in Brothers on June 27, 2010
+
+This was our second "return to flight" launch for the LV2 series. The airframe and recovery systems remained unchanged from [[last time|news/2009-05-31]]. We added a [[roll control module|rollcontrol]] to as a runner up to full active guidance. We rand an ARTS-2 board and a Telemetrum for the flight computers. It ran on a commercial N2000-w motor. This page is a master container for all the relevant data from the design and launch of the vehicle including pictures and video.

+
+## Design
+
+### Overview
+[[!img airframe/openRocket_labeled.png size="500x500"]]
+
+We started using Solid Works on academic licenses to model the entire rocket. This was a big success, tracking all of our parts and giving reasonably accurate CG and mass estimations as well as a bill of materials and assisting in the integration of new parts that fit and worked the first time.
+
+We also created a model in OpenRocket off the Solid Works data which resulted in accurate simulations of the flight.
+
+ - [The airframe CAD model is in our git repository](http://git.psas.pdx.edu/?p=airframe-cad.git;a=summary)
+ - [[OpenRocket model|airframe/LV2c.ork]]
+
+## Simulation
+
+ - Open Rocket driven
+
+### **Simulated** Launch Data
+
+This is the data run in advance, not taking into account the measured mass or cg, instead values taken from the Solid Works model.
