FL-60 uses flexible nozzle and its design Mach number is between Mach 0.3 and Mach 4.0.After put into use in 2014, FL-60 capabilities are increasing continuously and has completed several test campaigns.

To meet customers’ increasing requirements and expand wind tunnel capabilities, AVIC ARI decided to extend Mach number of FL-60 making use of existing equipment and system conditions after feasibility analysis. Rational risk prevention plan was mapped out to provide safety precaution for a smooth execution of this work. The capability to perform testing at Mach 4.2 was attained in June and it can provide service to customers now.
