In this mode we can create fuselage geometry file for PANUKL: Max. frame number defining fuselage geometry (frame No.0 counts in). Number of stringers on a single frame. Frame name syntax must be: [_.w] or [_.txt]. Where is the number of next frame (numeration starts from frame No.0). Frame No.0 point coordinates can be defined in . To use [name.txt] UNIGRAPHICS files in section select NX FILES check box and specify coordinate system for defining frame points: WCS or ABSOLUTE. Create fuselage geometry file button. Modification mode in FUSELAGE DATA Fig. 74 – Modify mode in FUSELAGE program In this mode we can modify existing fuselage geometry file. Things we can modify: Scale fuselage. EQUAL scale FACTORS can be used in every scaling direction (X, Y, Z). Translate fuselage. Translate to a specified X, Y, Z point location or delta translate: DX, DY, DZ coordinate increments must be defined. Translate fuselage only in XZ plane. Translation type selection. Click Modify button to accept changes and modify fuselage file. 64
4.4. How to export geometry from UG NX system to PANUKL software Export geometry procedure from UNIGAPHICS NX to PANUKL is only an example what we can do with available engineering tools. The export procedure can be used for complicated grids. It enables to export in detail 3D model geometry to PANUKL grid file. It is not optimized procedure it takes long but it works well. Below in document you will find a short description of procedure for preparing fuselage geometry for PANUKL in UNIGRAPHICS NX software. The example can show you the way to create your own PANUKL’s geometry files: [name.f], [name.ms2] & [name.prf] with a help of any available CAD tools. Export geometry procedure assumptions: we do have 3D model geometry file and we can open it in UNIGRAPHICS NX; we have basic knowledge about modeling in UNIGRAPHICS NX system. Example procedure Load 3D model geometry file. Translate geometry if necessary to (0,0,0) point of global coordinate system (nose of the aircraft is in (0,0,0) point, X axis to back, Y axis to the right wing, Z axis up). Trim right half of model with ZX plane. We will not use it. Fig. 75 – Left half of model in UG NX4, aircraft nose located in (0,0,0) of global coordinate system 65
