Project Goal: 

Develop a hybrid powered rocket compliant with Air Force safetydirectives and launch from Cape Canaveral Air Force Station

(CCAFS)to obtain trajectory data for NASA's UCAT program. 

Project Objectives: 

Collaborate with the 45th Space Wing to determine the optimalmethod 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

Fill System Slider Rail forOperational 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

The GallowsFill 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

Original rail removedduring Panther 1

Replace with hanging rail systemfor 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 45th Space Wing Certification

Mout – Exit mach numberP0 – Combustion chamber pressureA* - Throat Area - Regression rate of fuel a, n – Constants inherent to fuel

given by literatureGox – Oxidizer mass fluxAport – Area “seen” by combustionAburn – Surface area of burning surface - Volumetric flow rate of fuel Solve above two equations to determineappropriate geometry of fuel grain,Aport , Agrain, and length

Aport = 1.1 in2

Aburn = 125.5 in2

From regression eqns:Length of grain = 14.76 in

Shorter length to test mandril and mixing procedures
