First, ducted fans produce an air flow many times greater than a prop but they also lack the thrust of a prop due to the shorted diameter of the prop/fan. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which takes mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to accelerate air rearwards. outer diameter: 98mm. Eclipse has a cutaway nice jpeg though. 40 lbs thrust is limited by the tip speed of the fan (and not the deltaV of the airflow), according to the trusty internet but you are still limited by sonic airflow inside the duct. As this is significantly greater at higher thrust, reverse thrust should be used immediately after landing or RTO and, if conditions allow, should be reduced to idle by 60kts to avoid debris ingestion damage. Though the T-33AN was heavier than the T-33A, the Nene 10 engine produced 5,100 lbs of static thrust, 500 lbs more than the T-33A’s Allison J-33-A-35 engine. "Laaayyydies and Gentlemen.
