SUMMARY

This discussion focuses on the manufacturing of a half-span wing model for wind tunnel experiments, specifically using epoxy and micro glass beads injected into an aluminum mold. Participants suggest alternative methods, including machining from materials like G-10 or aluminum, and highlight the importance of considering application goals when selecting a manufacturing method. Rapid prototyping is also mentioned as a cost-effective solution for low-speed tests where surface finish is not critical.

PREREQUISITES
  • Understanding of wind tunnel testing principles
  • Familiarity with materials such as epoxy, micro glass beads, and G-10
  • Knowledge of machining processes for model fabrication
  • Experience with rapid prototyping techniques
NEXT STEPS
  • Research UK companies specializing in aluminum mold manufacturing for wind tunnel models
  • Explore machining techniques for G-10 and aluminum materials
  • Investigate rapid prototyping methods suitable for aerodynamic models
  • Study the impact of surface finish on wind tunnel testing results
USEFUL FOR

Aerospace engineers, model makers, and researchers involved in wind tunnel testing and aerodynamic model fabrication will benefit from this discussion.

Hi,

I am currently researching methods available for manufacturing a half-span wing model (approx 0.5m span, low sweep delta wing of varying cross section) to be used in wind tunnel experiments. A recent paper suggested the use of epoxy and micro glass beads injected into an aluminium mold for manufacturing the wing - do you know of any UK companies who provide this service or any other possible methods for producing a mold suitable for wind tunnel application? Any help or advice is much appreciated.

The best manufacturing method depends on the goals of your wind tunnel test. For example, you would have a very difficult time instrumenting a solid, injection-molded model like that if you planned to put pressure ports in it.

You might also try simply machining the model out of any number of materials, including G-10 (a glass-epoxy material) or aluminum or anything else. You just need to consider your application and goals when deciding.

If you are doing low-speed stuff around room temperature and surface finish isn't an issue, you may even be able to get it done very cheaply using rapid prototyping.
