Base Flow Analysis of Multiple-Engine Boosters.
Abstract
A method of predicting the base pressure and the base gas temperature of a multi-engine booster has been developed based on Korst's integral theory. The outer base region where the freestream-exhaust jets interaction takes place is analyzed by treating the outer boundary of the multi-jet exhaust plumes as an equivalent single-engine configuration so that the existing single-engine analysis method can be applied readily. Mass and energy transfer from the inner base region is calculated from the exhaust jet interaction analysis which includes the initial boundary layer. Solution is obtained from the net exchange of mass and energy between the outer and the inner base regions. The predicted results have been compared with flight data from the two-engine configuration Titan 3 B booster as well as with some available wind tunnel data on the four-engine configuration.
