vs Rafale
Basic hypothesis Rafale C and 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 and better Lift at high AoA (>2) for the Rafale. M88-2 and EJ-2 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-2 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 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 is still not fully open)
