The article demonstrates the results of experimental research of fracture kinetics for samples made of VT-20 titanium sheets under alternate stresses and at elevated temperatures. Dependences of crack growth rate on load parameters are obtained. The mechanism of regarding the influence of temperature and load non-stationarity on VT-20 fracture kinetics is proposed.

Keywords: kinetics, creep, crack, supersonic transport airplane, SST, titanium alloy.
