Transcribed Image Text:Boeing 747 civil transport airplane that is fitted by four high BPR turbofan engine similar to
CF6-50C turbofan engines. Each engine has the following data:
Thrust force
24.0 kN
• Air flow rate m (total)
125 kg/s
BPR
5.0
Fuel mass flaw rate m
0.75 kg/s
Operating Mach number
0.8
Altitude
10 km
• Ambient temperature T 223.2 K
• Ambient pressure Pa
• Fuel heating value Qhv
26.4 kPa
42,800 kJ/kg
If the thrust generated from the fan is 75% of the total thrust, determine
1. The specific thrust
2. TSFC
3. The jet velocity of the hot gases
(Assume that the exit pressure is equal to the ambient pressure.)
