+ 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 Design Engine one week
surfacing intensive.. This class is intended to
aid participants to master building critical air forms. Prior Pro/E surfacing with Pro/SURFACE and ISDX is necessary. No prior Aircraft experience is necessary.
Learn to develop lofted surfaces for managing lift with respect
to Reynolds values.
Discuss modeling techniques for developing Nacelles
Topics:
- Learn to use mathematically critical curves and surfaces.
- Learn to use conics and discuss strength of using conics over spines.
- Review ISDX (used
for blending at wing sections ie. wing fillets or nacelle)
- Lean to use trajpar Variable to drive critical math using air form
examples.
- Create wing fillets and wing tips and discuss concerns with respect to aerodynamics.
- 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 with respect to carbon fiber lay-up techniques.
- Learn about striation or flow of surface
- Manage concavity and discuss terminology with examples in Pro/E that aircraft
designers utilize with respect to bifurcation tubes and inlet ducts.
- Learn inherent issues and problems with 3 part boundaries
- Discuss modeling technique for creating Nacelles and inlet areas for
power plant.
- 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 aircraft
with surfaces.
- Learn to use the NACA aero foils generator for later import into Pro/ENGINEER
for wing developments.
- creator manipulate a stealthy drone Pro/ENGINEER model.
Discuss modeling technique for developing avionics pods.
Discuss wing fillets and wing tips.
Discussions:
- First and briefly discuss what you did not learn in PTC surfacing
workshops.
- discuss various workflow for choosing a NACA wing section and importing that form into Pro/ENGINEER for lofting wings.
- 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 modeling techniques for developing Nacelles with respect to performance and low observably.
- 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.
- Discuss utilizing internet resources for NACA sections
Computational Fluid Dynamics to evaluate turbulence
at velocity.
