+ Surfacing 'Aircraft forms' with Pro/ENGINEER

Course Duration: 16 hours

Tuition: $1500 USD

Overview:Discuss different surfacing styles and techniques using air forms as examples. Work with curve from points of . Learn to create and modify conics, spines, & curves with respect to air forms. Learn to use critical math surfaces with confidence in this workshop.

Prerequisites: This workshop is only for those designers or engineers who have at least taken the one week surfacing intensive offered by design engine. This class is intended to aid participants to master building critical air forms. Prior import experience with ISDX surfacing is necessary as this is an advanced class dealing with surface connections such as tangency and curvature at inlets and other NACA forms.

Learn to develop lofted surfaces for managing lift with respect
to Reynolds values.

Topics:

• Learn to use mathematically critical curves and surfaces.
• Learn to use conics and discuss strength of using conics over spines.
• Review Manipulate a curve through points using NURBS curves (used for blending at wing sections or nacelle)
• Lean to use trajpar Variable to drive critical math using air form examples.
• Create Transition areas. That geometry that joins wings to fuselage that are not as math critical.
• Utilize new skill sets to smooth out solid material from problem areas and to force rounds in transition areas.
  Building more robust curves and surfaces.
• Learn a workflow to use offset surfaces instead of the shell feature command.
• Learn about striation or flow of surface
• Manage concavity and discuss terminology with examples that aircraft designers utilize to communicate form.
• Learn inherent issues and problems with 3 part boundaries
  Discuss modeling technique for creating Nacelles and inlet areas for jet engines.
• Learn to use critical math surfaces with confidence in this class.
• Learn to utilize copy geometry to make for clearance of critical internal features. Utilize a workflow for managing clearance issues when designing with surfaces.
• Learn to use the NACA aero foils generator for later import into Pro/ENGINEER for wing developments.

Discuss modeling technique for developing avionics bay.

• First and briefly discuss what you did not learn in PTC surfacing workshops
• Discuss light reflections from a ground threat radar perspective. Lead a Stealth surfacing lecture.
• Discuss building robust curves and benefits there of
• Discuss the history of NACA and NASA and look at NACA forms as modeling challenges and discuss workflow issues for incorporating compartments.
• Compare other surface modeling software utilities to Pro/SURFACE
• Discuss leading edge, angle of attack, relative wind and cord length as related to modeling airfoils with Pro/SURFACE.
• Discuss various techniques for bringing in points from a spread sheet. making a wing cross section.
• Discuss proper technique for letting others to follow understand your approach to surface modeling.
• Discuss modifying other designers models.
• Discuss in detail surface analysis tools and discuss practical uses with examples.
• Discuss in detail techniques for avoiding 3 part boundaries and discover why expert surface modelers do not use 3 part boundaries. (even masters of surfacing for reverse engineering)
• Discuss creating lofts between various cross sections with examples using air forms as examples.
• Discus nacelle modeling challenges.
