  • I wonder if that shares the same physics as silvent’s compressed air guns.

    Silvent’s air nozzles reduce the sound level when blowing with compressed air compared to blowing through open pipes. This is due in part to the reduction in noisy turbulence from using Silvent’s air nozzles, and also because of the nozzles’ special design. Silvent’s air nozzles pass the compressed air through small holes and slots, which raises the sound to frequencies beyond what the human ear can perceive. This allows us to make blowing with compressed air both quiet and efficient.

    Could use an even quieter compressed air gun












  • Is it surprising that a publicly traded company is going to drive down quality to meet (or in spirit areospace’s case - attempt to make) profits?

    The union also has clashed with Spirit over whether machinists should ever be responsible for checking their own work. Workers say having separate inspectors sign off on individual work is critical for quality control; Spirit and Boeing executives say that technological advances have reduced the need for separate inspectors in some cases.

    Bad bad idea. Do not let machinists sign off on a inspection report. The incentive to hide mistakes is far too great.







  • Most, if not all, aerospace tools that take a measurement requires periodic calibration and assurance that the tool is performing to spec.

    There can be thousands of unique tools that must pass through its own respective calibration process and documentation. Micrometers, calipers, torque wrenches, and even scales.

    Having a networked tool can save the hassle of operators mis-reading or just plain ignoring the calibration sticker. Also, knowing the “location” of the tool on an inventory sheet isn’t quite like knowing which side of a 747 for the wrench that is due for calibration.

    Also this is just me hypothesizing… I presume there are a number of other benefits like automated logging of torque values for every single bolt installed with such tool. When the FAA audits for installation information regarding a single screw on a plane’s 3rd row window side infotainment system’s upper left mount… The data is easier to find.

    This is all part of “industry 4.0” connected manufacturing for more efficient and lean manufacturing. Collect and process any data you could ever want to make the decisions for a manufacturer to do more with even less.
