Why Simulations? • Low risk • Compara-vely low opera-on of cost
• New skills learned • Alterna-ve to physical training
• Must be realis-c
• Quick tes-ng methods • Current method at Ames is the Ver-cal Mo-on Simulator (VMS) VMS visual model of the Large Civil Tilt Rotor 2

Converting New Models PROBLEMS
• X-‐Plane requires X-‐Plane specific .acf file • X-‐Plane specific .acf files can only be compiled in Plane-‐Maker
• Plane-‐Maker only imports X-‐Plane specific .obj files
• Plane-‐Maker only imports as objects
MORE PROBLEMS
• VMS models came as .obj files (not X-‐Plane compa-ble)
• Rhino does not export to X-‐Plane specific files • AC3D only opens 3ds files
• AC3D only exports files with one texture per geometry

Integrating New Models (cont.)
.obj VMS .3ds Rhino .obj AC3D .acf Plane-‐Maker
X-‐Plane
• Models were obtained from the VMS • .obj • .3ds • .flt
• Textures • .-ff • .-ff.aKr
• Convert .-ff files to .png files

Integrating New Models (cont.) • Convert novel aircra` to test handling capabili-es
• This process is less than ideal • Started a plug-‐in to make this process simpler
