+Advanced Pro/SURFACE Level 2A Workshop 'air forms'

Course Duration: 16 Hours

Tuition: $1200.00 US

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

Prerequisite: Design Engine Level 1 Surface Workshop.

Topics:

• Learn to use mathmaticly critical curves and surfaces.
• Learn to use conics and discuss strength of using conics over splines.
• Review Manipulate a curve through points using nurbs modeling techniques (TWEAK).
• Lean to use trajpar Variable to dirve 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.
• Eliminate isoparms (what PTC calls isolines) and discuss tangency issues.
• Learn about striation or flow of surface.
• Manage concavity and discuss terminology with exampels that aircraft designers utilzie to communicate form.
• Learn inherent issues and problems with 3 part boundaries
• Discuss modeling techniqe for creating Nasells 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 clearace issues when desinging with surfaces.
• Learn to use the NACA aerofoils generator for later import into Pro/ENGINEER for wing developments.
  
  

critical surface geometry created from specific cross sectional geometry.


Critical surface geometry that is drivin from trajpar variables for mathamaticly correct geometry.

Discussions:

• First and briefly discuss what you did not learn in PTC surfacing workshops
• Discuss light reflections from a ground threat radar perspective.
• 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 attak, realatvie wind and cord length as related to modeling airfoils with Pro/SURFACE.
• Discuss varius tecniqes fcr 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 betwee varius cross sections with examples using airforms as examples.
• Discuss ergonomic forms for creatign hand controls as examples.
• Discus nacelle modeling challenges.

instruments reside inside this nacelle housing. In this modeling challenge participants will discuss plan of attack for tackleing clearnance and modeling issues.
