Abstract:

A study was conducted to develop an analytical model for the investigation of flow fields about intermediate disc loading lift devices for VTOL applications. Classical vortex-lattice theory was used in conjunction with experimental data for representing a free propeller in a crossflow. The jet phenomena to be simulated by the method are discussed. A number of previous attempts at vortex-lattice modeling are presented. Analytical stream lines and field vectors are compared with available experimental data. The results are evaluated and recommendations are made for further model development.
