1. TESLA Rocket Internship 11/29/2016

2. Team Task Assignment Discussions
From Last Class
Team Task Assignment Discussions
Download copy of either “Open Rocket” or “RASAero”
Print rocket cross section?
Challenge Questions
What is our total impulse
What is the Isp of the liquid engine
What is the expected apogee altitude
Sea level launch altitude
100 lbf main engine
30 sec burn time
45 lbf BOL mass

3. Terms Total Impulse (Itot) = Thrust * Burn Time
{100 lbf * 30 sec}ligud + {125 lbf * .8 sec}solid
3100 lbf-sec
13,789 N-sec
Specific Impulse (Isp) = Thrust / Propellant mass flow rate (mdot)
100 lbs (for the main engine)
0.445 lbs/sec
Isp = 225 sec
