    Results of numerical research of aerodynamic characteristics of an airship with and without tail having various form of airship body cross-section when an airship pass es through an ascending air stream of the limited cross-section size. Influence of a relative positioning of an airship and a stream on sizes of aerodynamic factors of an airship is determined.ΠŸΡ€ΠΈΠ²ΠΎΠ΄ΡΡ‚ΡΡ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ числСнного исслСдования аэродинамичСских характСристик Π½Π΅ΠΎΠΏΠ΅Ρ€Π΅Π½Π½ΠΎΠ³ΠΎ ΠΈ ΠΎΠΏΠ΅Ρ€Π΅Π½Π½ΠΎΠ³ΠΎ корпуса дириТабля с Ρ€Π°Π·Π»ΠΈΡ‡Π½ΠΎΠΉ Ρ„ΠΎΡ€ΠΌΠΎΠΉ Π΅Π³ΠΎ ΠΏΠΎΠΏΠ΅Ρ€Π΅Ρ‡Π½ΠΎΠ³ΠΎ сСчСния ΠΏΡ€ΠΈ ΠΏΡ€ΠΎΡ…ΠΎΠ΄Π΅ дириТабля Ρ‡Π΅Ρ€Π΅Π· восходящий Π²ΠΎΠ·Π΄ΡƒΡˆΠ½Ρ‹ΠΉ ΠΏΠΎΡ‚ΠΎΠΊ ΠΎΠ³Ρ€Π°Π½ΠΈΡ‡Π΅Π½Π½ΠΎΠ³ΠΎ ΠΏΠΎΠΏΠ΅Ρ€Π΅Ρ‡Π½ΠΎΠ³ΠΎ Ρ€Π°Π·ΠΌΠ΅Ρ€Π°.

    THE AERODYNAMIC CHARACTERISTICS OF A SOFT TYPE AIRSHIP NEAR TO A SCREEN IN VIEW OF A PROPELLER JETS INFLUENCE

    No full text
    The results of numerical research of a soft type airship aerodynamic characteristics in subsonic flow of viscous gas are received for the airship locating near to a screen and having the working propellers. The influence of propeller rotation and relative distance of the airship to the screen on values of its aerodynamic normal and longitudinal forces, and also pitching moment is shown at various airship angles of attack
