2. Project Goal: Develop a hybrid powered rocket compliant with Air Force safety directives and launch from Cape Canaveral Air Force Station (CCAFS) to obtain trajectory data for NASA's UCAT program. Project Objectives:  Collaborate with the 45 th Space Wing to determine the optimal method of launching a hybrid rocket from CCAFS  Build rocket following method provided and launch  Construct ground support equipment necessary to facilitate a launch  Retrieve trajectory data from the rocket for use in NASA’s UCAT program 2

3. 3 Fill System Slider Rail for Operational Test Fires o Made from excess aluminum C-Channel and 80/20 extruded launch rail. o Teflon spray allows for smoother movement and operations of Fill System o Held by C-Clamps for stability and alignment with thrust stand

4. 4 The Gallows Fill lines and fill assembly tether o Designed to catch fill assembly after ejection from combustion chamber o Routes N20 and GOX fill hoses from tanks to fill assembly o Ground stakes and rope provide extra stability

5. 5 Original rail removed during Panther 1 Replace with hanging rail system for Panther 2

6.  Basic stress: τ = F/A  Moments: M = F*d  We must calculate for a worst case scenario event of a full thrust maximum moment hang fire  Possible ANSYS analysis for 45 th Space Wing Certification 6

7. 7 M out – Exit mach number P 0 – Combustion chamber pressure A * - Throat Area - Regression rate of fuel a, n – Constants inherent to fuel given by literature G ox – Oxidizer mass flux A port – Area “seen” by combustion A burn – Surface area of burning surface - Volumetric flow rate of fuel Solve above two equations to determine appropriate geometry of fuel grain, A port, A grain, and length

8. 8 http://www.aeroconsystems.com/misc/mandrils/98mm_Star.gif A port = 1.1 in 2 A burn = 125.5 in 2 From regression eqns: Length of grain = 14.76 in

9.  Shorter length to test mandril and mixing procedures 9 Fire goes through here Sunbeam mixer
