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

Blog Article

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 Autres 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 Pop-Up Sofabed longitudinal forces, and also pitching moment is shown at various airship angles of attack.
