Aerodynamic coefficients of the anti-armour aviation bomb (AAAB) are determined in subsonic and transonic flow field regimes in the wind tunnel. These flow conditions directly affect the fuze arming mechanism time of the bomb. An alternative and reliable method for the fuze arming time measuring in relation to the expensive flight tests is defined in the paper. Verification of the method will be performed in the real flight conditions after the wind tunnel testing.

Key words: aviation bomb, anti-armour aviation bomb, fuze arming, aerodynamic performances, aerodynamic coefficients, aerodynamic  testing, wind tunnel.
