Identification of Traction and Power Characteristics of Air-Screw Propulsors in Mathematical Description of Airship 2014-01-2134
The paper formulated and solved the problem of investigating the traction and power characteristics of air-screw propulsor for airships. The study is performed by constructing a mathematical model relating the steady-state values of the shaft power and traction on the axis of the screw with the velocity of rotation and the actual velocity of the aircraft. Proved design scheme selection of computer simulation of aero-and thermodynamic processes occurring during rotation of the airscrew. Describes plan developed under the experimental task, providing variation in the basic parameters of the airscrew, motion parameters and flight environment The results of computer modeling of the interaction of the airflow with the airscrew at various combinations of these parameters.
Results are shown in tabular and graphical form and as a mathematical model of the studied airscrew. Importantly, by developed and tested the method can construct mathematical models of airscrew propulsors any specific structures and geometrical parameters. This result is extremely important and useful for solving problems related to the selection, design and optimization of airscrew propulsors of airships and other aircraft with airscrew propulsors. These results are important for the development of motion control systems aircraft.
