[Q2, 5 pts] Which оf the fоllоwing аre аdvаntages of a staged-combustion cycle? (Select all that apply) The turbine exhaust is routed into the main combustion chamber and ultimately expanded through the main nozzle, allowing more effective use of the propellants. The closed-cycle arrangement can provide high specific impulse because the turbine-driving flow contributes to engine thrust. The cycle supports high chamber-pressure operation while maintaining efficient utilization of the propellants. The engine requires fewer components and a simpler control system. The turbopumps do not need to raise the propellant pressures above the main-chamber pressure because combustion in the preburners provides the remaining pressure rise.
