  1. Dana LattibeaudiereFebruary 7, 2008New Code Developments AAE 450 Spring 2008

  2. New Code: ma_thrust.m • More outputs: => Structures • nozzle diameters/lengths, engine masses, pressures of oxidizer and fuel tanks, fuel and oxidizer mass flows • Assumptions: • Theoretical hybrid engine • Pc estimated • Conical shaped nozzles, 12 deg • Tank Pressure: no P_dynamic, P_throttle AAE 450 Spring 2008

  3. Sample Output: • Tvac = 44.48 kN • Nozzle Diameter = 2.016 m • Engine mass = 43.84 kg • Nozzle length = 4.387 m • Pressure fuel = Pressure Ox = 1.73E6 Pa Future Work • Integrate code • CAD AAE 450 Spring 2008 Propulsion
