1. A powerplant, comprising:
a first gas turbine engine including a first inlet, a first exhaust, a first compressor section, a first combustor section, a first turbine section and a first core flowpath fluidly coupled with and between the first inlet and the first exhaust, the first core flowpath extending sequentially through the first compressor section, the first combustor section and the first turbine section;
a second gas turbine engine including a second inlet, a second exhaust, a second compressor section, a second combustor section, a second turbine section and a second core flowpath fluidly coupled with and between the second inlet and the second exhaust, the second core flowpath extending sequentially through the second compressor section, the second combustor section and the second turbine section;
a second engine bypass flowpath bypassing the second core flowpath; and
a flow control system configured to fluidly couple the first inlet and the first exhaust to the second core flowpath during a first mode, and the flow control system configured to fluidly couple the first inlet and the first exhaust to the second engine bypass flowpath during a second mode.
