Daniel: This is an interesting question and I would answer by saying no, high-bypass turbofans are NOT a species of turboprop. My reasoning is that the rotational motion of the tubine shaft of a turboprop turns a reduction gear to reduce the rotational speed of the propeller. The compressor blades of the turbofan do not have this feature, they are turning at the same speed as the spool that they are mounted to. I'm no expert, just my opinion. -- Martin Sagara Volunteer Staffmember Wings Over The Rockies Aviation & Space Museum Hangar 1, Old Lowry AFB Denver, CO USA firstname.lastname@example.org "Visualize Whirled Peas"
