AN ANALYTICAL AND EXPERIMENTAL STUDY OF A CRYOGENIC EVAPORATOR FOR SPACE APPLICATION.
Abstract
The report is concerned with an analytical and experimental study of a heat exchanger which is to be used as a component part of a low thrust, space vehicle, propulsion unit. The necessary heat to operate the exchanger is taken from internal space-craft surroundings (i.e. reactor, electric motor, electric generator, etc.). Conduction is assumed to be the primary mode of heat transfer into the exchanger. The primary purpose of the heat exchanger is to change the cryogenic liquid propellant into a gas. The propellant gas from this evaporator is accelerated through a nozzle to produce small thrusts. The theoretical analysis considers only steady state temperature characteristics of the evaporator. These characteristics are compared with experimented observations. From these comparisons conclusions are drawn concerning the feasibility of using the analytically developed equations to construct an evaporator for practical use. (Author
