Such engines are composed of several modules, each of which consists of an air-intake, a combustion chamber and a nozzle, and these modules are attached side by side to the bottom surface of the fuselage of a vehicle. Under such configuration, it is considered that when some disturbances make one of the modules to be unstarted, such influences propagate to the adjoining modules through the intake and/or the nozzle, and that the normal operation of the propulsion system should be destroyed. In this study, such interactions between modules of the airframe-integrated scramjet engines are investigated numerically. As disturbances to trigger unstart of the module, shock waves generated by thermal choke in the heating region of the module is used. The flow field to be two-dimensional including the yaw cross section of the modules is approximated. An inviscid compressible flow is assumed, so Euler equations with heating term are used as the governing equations. Explicit symmetric TVD (Total Variation Diminishing) scheme is used. From the two-dimensional calculations, the following conclusions are obtained: 1) When thermal choke occurs in one module of a scramjet engine, its influence reaches the adjoining modules through shock wave propagation and they become unstarted. 2) The transient process from the started condition to unstarted is completed in about 30 msec and the unstarted modules generate not thrust but drag.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
