Chamber/single nozzle
Notional LOx/LH2 rocket engine. Study 1963. Before moving to favored plug nozzle designs, Bono at Douglas considered having multiple combustion chambers exhaust into a single large nozzle to obtained Improved Specific Impulse.

Status: Study 1963. Thrust: 13,231.00 kN (2,974,447 lbf). Specific impulse: 455 s. Specific impulse sea level: 365 s. Burn time: 249 s.

Used in Nova DAC ISI, ROOS ISI, OOST ISI, and DAC Helios ISI designs. Status: Study 1963. Operational date would have been July 1977. Values shown were maximum considered.
