Аннотация:A code for the synthesis of light curves of close binaries in the Roche model is proposed which incorporates a stellarwind around one of the stars. The code makes it possible to analyze observations of binary systems containing Wolf-Rayetstars. This paper presents the results of the application ofthis code to the spectroscopic binary WR22, whose componentsare stars of spectral types WN7h and O9III-V (P= 80.336d,e∼0.6). The light curves were obtained with one of theBRITE-Constellationspace-based telescopes. Two solutions to the problem were found, corresponding to two possibleluminosity classes of the O star, O9III and O9V. For each solution, the orbital inclination, the masses of the components,the temperature of the WR star, the WR mass-loss rate, and other parameters were determined. The resulting stellarparameters favour the solution for the WN7h+O9V model
