 | | At the same time, however, TsAGI did comprehensively explore the behaviour of FSW air-craft in the wind tunnel, over a wide range of speeds (from Mach 0.2 to Mach 2.0) and at various angles of attack (up to 800). |
 | | Early TsAGI FSW models were based on the MiG23 and similar work was undertaken at Novosibirsk, on a modified Su-27. |
 | | Later, large leading-edge wingroot exten-sions were introduced which, together with the canards, prevent-ed stall of the airflow over the wings, improving the lift at high angles of attack. |
