Question 61
AENAT2 marksNeeds review
An ideal turbofan with a bypass ratio of 5 has core mass flow rate,
kg/s. The core and the fan exhausts are separate and optimally expanded. The core exhaust speed is 600 m/s and the fan exhaust speed is 120 m/s. If the fuel mass flow rate is negligible in comparison to
, the static specific thrust (
) developed by the engine is ____ N s/kg (rounded off to the nearest integer).Log in to check the answer
