Abstract

The requirements on the use of titanium alloys used as thermal protection in hypersonic airplanes are considered. The ignition of titanium alloys in aerodynamic heating is analyzed. A mathematical model is proposed for the surface oxidation of the alloys in a high-temperature air flux.

Keywords

hypersonic airplane, aerodynamic heating, thermal protection, titanium alloys, ignition, surface oxidation, mathematical models
