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.ΠΡΠΈΠ²ΠΎΠ΄ΡΡΡΡ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ ΡΠΈΡΠ»Π΅Π½Π½ΠΎΠ³ΠΎ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ Π°ΡΡΠΎΠ΄ΠΈΠ½Π°ΠΌΠΈΡΠ΅ΡΠΊΠΈΡ

AERODYNAMIC CHARACTERISTICS OF AN AIRSHIP DURING ITS MOVEMENT THROUGH THE ASCENDING AIR STREAM
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
THE AERODYNAMIC CHARACTERISTICS OF A SOFT TYPE AIRSHIP NEAR TO A SCREEN IN VIEW OF A PROPELLER JETS INFLUENCE
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
