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 opi chill em with kindness 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 replica grease gun is shown at various airship angles of attack.
