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 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 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 Original rail removed during Panther 1 Replace with hanging rail system for Panther 2
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 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 A port = 1.1 in 2 A burn = in 2 From regression eqns: Length of grain = in
Shorter length to test mandril and mixing procedures 9 Fire goes through here Sunbeam mixer
