  2. Propellant Selection • Cryogenic: LOX/LH2, LOX/RP-1, LOX/N2H4 • Toxic: H2O2/N2H4, ClF5/N2H4, N2O4/RP-1 • Hybrid: LOX/HTPB, H2O2/GAP, H2O2/PEG • Solid: DB/AP-HMX/Al, HTPB/AP/Al, DB/AP/Al • Nicole’s code: stage mass, prop masses/costs AAE 450 Spring 2008 Propulsion

  3. Thrust Code Analysis • RD-161-2: • T_vac = 19.9 kN, t_b = 900 s, Ae = 0.82 m^2, • LR-101-11 • T_vac = 5.3 kN, t_b = 283 s, Ae = 0.2 m^2, Future Work • Complete the code • Reference for optimization groups AAE 450 Spring 2008 Propulsion
