ABSTRACT:
The invention is a propulsion system for powering an aircraft in both vertical and horizontal flight modes. In detail, the invention includes a pair of ducted lift fans mounted in the aircraft for providing thrust in the vertical flight mode. A pair of ducted cruise fans are mounted in the aircraft for providing thrust in the horizontal flight mode. Two sets of turboshaft engines are mounted in the aircraft with each of the sets comprising a plurality of the turboshaft engines, each turboshaft engine including an output shaft and having an optimal power output sufficient for powering one of the pair of ducted cruise fans in the horizontal flight mode. Each of the sets includes a sufficient number of the turboshaft engines to provide an optimal power output for powering one of the pair of ducted lift fans and one of the pairs of ducted cruise fans the vertical flight mode. A shafting system is mounted in the aircraft for coupling all of the turboshaft engines to the pairs of ducted fans. A first decoupling system is connected to the shafting system for decoupling the pair of ducted lift fans from the sets of turboshaft engines. Finally, a second decoupling system is connected to the shafting system for individually decoupling each of the turboshaft engines from the shafting system.
