You know, if the design is anything like the larger turbofans, you'll have the fuel economy and thrust that everyone is craving for!!
Only problem I forsee is sizing of the fan unit at the front of the turbine. Just like the big boys, the turbine used will still hold it's standard dimensions. The fan will have a larger OD than the turbojet itself, if this design is going to be the route of standard turbofan designs. May be suitable only for larger airframes. Still would love it and have been waiting for someone to pull it off, figured it would only be a matter of time before someone does.
