Abstract Analysis and design of an optimum LO2/LH2, combustion topping cycle, 88,964 N (20,000-pound) thrust, liquid rocket engine was conducted. The design selected is well suited to high-energy, upper-stage engine applications such as the Space Tug and embodies features directed toward optimization of vehicle performance. A configuration selection was conducted based on prior Air Force Contracts F04611-71-C0039, F04611-71-C-0040, and F04611-67-C-0016,.and additional criteria for optimum stage performance. Following configuration selection, analyses and design of the major components and engine systems were conducted to sufficient depth to provide layout drawings suitable for subsequent detailing.
