Page 6 TESLA Rocket Mdot total =0.445lb/sec Mdot Fuel = 0.194lb/sec Mdot OX = 0.252lb/sec Qdot Fuel =6.361in^3/sec Qdot Ox =6.106in^3/sec Isp = 239 sec What is the thrust of our engine? {F = Isp * Mdot}
Page 7 Launch Rail Preliminary Requirements Launch Requirements 100 FPS at release of first launch lug, we could justify 80 fps 40’ length for starters Minimize tip-off – No addition launch force applied at point where launch lugs release Currently need ~180’ launch rail if we rely on the liquid engine alone! What do we do to achieve additional velocity?
