## <a name="Prototype Motor Parameters"></a> Prototype Motor Parameters

----

The following design parameters where selected to begin the process of evaluating paraffin as a potential hybrid motor fuel. We want to design a motor that will be easy to set-up and fire an also be inexpensive to test.

**Preliminary motor specifications:**<br /><br /> Average thrust: 50 lbs <br /> Burn Time: 15 seconds <br /> O/F: 2.7 <br /> Paraffin grain diameter: 2.00" <br /> Paraffin grian length: 5.50" <br />
