        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "A propfan is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The engine uses a gas turbine to drive an unshielded propeller like a turboprop, but the propeller itself is designed with a large number of short, highly twisted blades, similar to a turbofan's bypass compressor (the \"fan\" itself). For this reason, the propfan has been variously described as an \"unducted fan\" or an \"ultra-high-bypass (UHB) turbofan\"." ] ,
