A Design Study in Steel - Crossbleed Valve for the F-5
Lessons
Learned
The
redesign of the gating system for the crossbleed valve was an excellent
demonstration how the casting design process can produce cost-effective
solutions to production problems.
Major lessons learned
were:
Controlled
solidification can be produced in isolated hot sections by well
thought-out design of the gating on the casting. This
ensures a flaw-free, in-spec component.
Close
communication with the end-user was necessary to approve the
design change needed to achieve the directional solidification.
The
investment casting design can be easily modified by low-cost
additions and deletions to the wax pattern.
