The results of experimental investigation on aerodynamics of the two experimental flight test vehicle EFTV options (powered and glider ones) which are under study within the international project HEXAFLY-INT are presented. The tests were performed in TsAGI supersonic and hypersonic wind tunnel T-116 at Mach numbers from 3 to 8. Particular attention is paid to aerodynamic efficiency and trim-ability of the vehicles. It is shown that at Mach number M = 7 maximum aerodynamic efficiency of both the EFTV powered option with started intake and the glider option is of approximately the same value (L/D)max ≈ 4.5, and problems with trim-ability on pitch occur just for the powered option if the intake is not started.
