  • SYSTEM AND METHOD FOR AUGMENTING A PRIMARY POWERPLANT
    Publication number: 20180118364
    Abstract: An aircraft propulsion system includes a fan, a primary powerplant, an augmenting powerplant and a controller. The primary powerplant is coupled to the fan and configured to rotate the fan during a first flight stage and during a second flight stage. The augmenting powerplant is coupleable with the fan. The controller is configured to cause the augmenting powerplant to drive the fan during the first flight stage, and to cause the augmenting powerplant to cease driving the fan based on an indication of a transition from the first flight stage to the second flight stage.
