Abstract

In the core of a nuclear rocket engine the propellant is heated from a temperature near its boiling point to a temperature limited only by the structural materials of the core. Using hydrogen as the propellant, the ratio of the core exhaust temperature to the core inlet temperature may be as large as 20 to 30, Under strong heating conditions, the distribution of flow among the parallel channels of a heat exchanger may be unstable at low flow rates. Consequently, the reactor is designed so that at normal operating conditions the flow is well above the flows at which instabilities may occur. During the start-up and shut-down operations the reactor must operate temporarily in the unstable region.
