Urgent Test Requirements
While we do not recommend working under such conditions, we are sometimes asked to help with urgent test requirements with little time to prepare.
We were recently contacted with very short notice for a thermal vacuum test requirement. Less than two weeks after receiving the test procedure document we had begun the test and, even with the chamber not being configured how we would have liked it and the test procedure being altered by the customer 'on-the-fly', the test was completed on schedule. The results of the test were critical to the acceptance of a flight component and as such the customer was able to meet their deadline due to our rapid response.
Large Sample Loads
A customer requirement for baking out hundreds of thermocouples meant pushing the capacity of our TVAC chamber. The down-time between bakeouts gave us a week to measure, design, manufacture, clean and fit spool system for loading the thermocouples. We were constrained by our temperature controlled shroud, but we were able to fit the components in time and complete the bakeout.
Tricky Sample Loading
Our chamber can be fitted with a large a range of temperature controlled shrouds we have manufactured for it. However, we are able to manufacture new shrouds to accommodate samples which are more tricky to mount.
For this particular bakeout the samples need to be suspended in the center of the chamber. We were able to get a design to our highly skilled engineer within the day and continued the re-configuring of the chamber while the machining was being undertaken. Computer controlled DC power supplies were installed into the control rig and the PID software updated to take care of the temperature control of the multi-segment shroud. In a week we had the new shroud installed along with re-routed thermocouples, QCM and cold plate lines. The bakeout was then started on-schedule thanks to our quick turnaround.
As a small company we are remarkably agile in terms of design, manufacture and installation of test equipment for our in-house test services. This allows us to quickly respond to our customer's test requirements by getting custom components machined and fitted. For our customers, this quick turn around can mean the difference between meeting or missing a deadline.
