JET BLAST COMPARISON of Pratt & Whitney JT3D or TF33PW100A Engines on the Boeing 707 or in the video the Boeing E3A Sentry vs. the CFM Internation CFM565CA4 on the Airbus A340313X vs. RollsRoyce RB211 Trent 556A261 on the Airbus A340642X.
The JT3D is a low bypass turbofan engine derived from the J57 Turbojet in the early 1960s. The CFM565C is a high bypass turbofan twospool engine exclusivly powering the Airbus A340300 with a wider fan diameter compared to the CFM565B which powers the Airbus A320family. The RollsRoyce Trent 500, here the Trent 556A262 is an threespool engine developed from the famous RB211 and is still a member of the RB211 family. The engine is the only engine option on the Airbus A340600 available.

Stats:
JT3D: 130cm Fandiameter, 1.42:1 Bypass ratio , 95,64kN Thrust
CFM565CA4: 184cm Fandiameter, 6.4:1 Bypass ratio, 151kN Thrust
RR Trent 556A261: 247cm Fandiameter, 7.5:1 Bypass ratio, 260kN Thrust
