Annotations languages:

In the article the results of experiment in a wind-channel with the models of fuselages with the equal areas of midelevih sections of three-cornered and round form for determination of correlation between the level of radio-location noticeable and aerodynamic perfection at the change of form of fuselage of airplane are presented. As a result of the experimental data processing dependences of coefficients of head-resistance, carrying capacity and aerodynamic quality from the corner of attacks are collected. On the basis of analysis of the got dependences conclusions on distinction of character of flowline of fuselages of three-cornered and round form of transversal section around are done.
