  • 1. Typhoon vs Rafale
  • 2. Basic hypothesis• Rafale C and Typhoon share the same aerodynamic configuration, means same CL (lift) and CD (drag) coefficients law [Cx(Mach, AoA)]. This is known as not realistic, but I do not have reliable data to differentiate them. – Subjective position may give less Drag at high Mach number to the Typhoon and better Lift at high AoA (>20) for the Rafale.• M88-2 and EJ-200 share same Thrust Profile (coefficient between static thrust and actual thrust at a given altitude and Mach number configuration) under M=1.8 , even mounted behind 2 very different air intake, EJ-200 thrust is assumed to decrease only after M=2.2. This is known as not realistic, but I do not have reliable data to differentiate them.• Rafale C and Typhoon share Fly Control limits (AoA limitation versus G factor). This is known as not realistic, but I do not have reliable data to differentiate them. – Non confirmed information indicated higher AoA values allowed for the Rafale (Flight envelop of the Typhoon is still not fully open)

Horizontal evolution capabilities of the two planes are very similar. Rafale Typhoon

Configuration for 45’ Cruise• Cruise is supposed to be at FL300 and Mach=0.9, no external loads, and without after burner (fuel consumption is supposed to be the best specific one gave by engine manufacturer)• Rafale C (M88-2) – cruise configuration sustained with a thrust of 3,737 lbs leading to a fuel flow of 2,933 lbs/h, – 45 minutes of fly in such condition require 2,200 lbs of fuel, given a gross weight of 22,175 lbs• Typhoon (EJ-200) – cruise configuration sustained with a thrust of 4,040 lbs leading to a fuel flow of 3,289 lbs/h, – 45 minutes of fly in such condition require 2,467 lbs of fuel, given a gross weight of 26,749 lbs

Horizontal evolution capabilities of the Rafale are better. Typhoon Rafale
