The speed envelope discussed is much faster than i thought straight non-swept wings could manage. Same for propeller thrust.
What am I missing? Aircraft are such illustrative examples of the whole concept of tradeoffs.
- asdfadsfgfdda 7y agoA CitationJet can reach ~420 knots cruise with straight wings. For propulsion, seems that they become a "hybrid" with propeller thrust and some jet thrust from their exhaust nozzle. This is similar to a P51, which generated some thrust with radiator exhaust.
- gwicks56 7y agoI assume its a function of altitude? Not much air at 60, 000 feet. Although the same goes for the propeller I guess. The altitude would certainly be where the efficency comes from, but it's such a simple solution, there must be very good reasons commercial don't already fly that high.
