    Blindmate Mil 83513 Connector Accessories?

    I have searched ITT Cannon and Glenair but have been unable to find any hardware for blindmating Micro-D Mil 83513 type connectors. Does anyone have info to share?

    Metric Fastener Part Numbers

    GSFC lists the following type of part numbers for metric washers; 722-95-029-xxx-x or 722-95-030-xxx-x (the x's represent variable info). Does anyone know what spec covers these part numbers? Also, they list the preferred washer type as NA0034 which is a nut with "extended washer" a kind of...

    Metric Fastener Part Numbers

    The metric pan head screw I referenced (NA0068) does indeed look like an Imperial/English cheese head. Take a look at this Goddard Space Flight Center (GSFC) site for some more info on this: http://supply.gsfc.nasa.gov/fasteners/met_inv.htm Does the AIA not have metric structural screws?

    Metric Fastener Part Numbers

    Thank you alexit and yates. Of course, right after I posted this question my constant searching got me the correct info. I believe I have found what I was looking for in AIA NA standards. Strangely enough I had to search on exactly the opposite of what I wanted; MS51957 imperial screws, to...

    Metric Fastener Part Numbers

    I work for an aerospace, defense electronics manufacturer. We work with primarily with Imperial/English fasteners (2-56, 4-40, etc.) and due to our industry, we always reference MS or NAS part numbers (MS51957, NAS620, etc.). I would like to know if metric fasteners are detailed in a similar...

    Neoprene and JP-4 Jet Fuel

    This is an electronics assembly, and the neoprene would be used for four vibration isolators. The assembly would be located in an avionics compartment and should only be exposed to fuel vapors. Would you anticipate any problems with this situation?

    Neoprene and JP-4 Jet Fuel

    We are in the process of designing an assembly that must use a vibration dampener made of neoprene. This assembly will be used in an aircraft and will be obviously exposed to fuel vapor. I have done a little searching and see that some protective gloves made for handling jet fuel are neoprene...

    Calculated Moments of Inertia

    I want the moments of inertia for each part rotated about the X, Y & Z axis.

    Calculated Moments of Inertia

    I have a 3D design of a housing and covers and require the MOI for each part. I hope this helps.

    Calculated Moments of Inertia

    I have CAD models and the software I used (Mechanical Desktop) is capable of calculating moments of inertia. However, three different versions are returned; (1)Mass Moments of Inertia (2)Mass Products of Inertia & (3)Principal Mass Moments. The coordinates for (1) are given in Lx, Ly & Lz, for...

    Drawing approvals

    BML- The problem coordinating the EDMS system date and the date on the drawing would still exist. And making the revision part of the part number is a BIG no-no. Not only does it violate Mil standards, but everytime you revise a drawing it would necessitate a revision to all Parts Lists...

    part numbers, how many digits do you have?

    What industry are you in?

    Drawing approvals

    Won't the names associated with ECN's lead to the same problem as the initial release (disagreement between the document and the management system)?
  14. billtati

    Drawing approvals

    Is this statement IN PLACE OF the approval names & date? or IN ADDITION to the approval names & dates?

    Outgassing data for Iridite 7p

    Iridite provided corrosion resistence, and Class 3 is electrically conductive.

    Drawing approvals

    Mandrake- I have the full version of Acrobat, but the engineers do not. Hence the in-quotes "uneditable" phrase. And if we did allow editing of the .pdf file, the next revision of the base document would print to a .pdf without correct signature & dates. Each change to a .pdf would necessitate...

    Outgassing data for Iridite 7p

    I am not sure about your question, but confirm the environment of your application as iridite will actually flake off as a powder if exposed the the correct conditions (temp, etc) in space. We generally do not use iridite for space applications and in fact some customer specifically do NOT want...

    Drawing approvals

    In our design dept we use several CAD applications. When sending a drawing for approval via our Electronic Document Control System (EDMS) we either send the actual file or an Adobe Acrobat .pdf version. In most cases the engineer approving the drawing does not have access to the software that...

    Fastener Selection and Part Number Guide

    Thank you for the link. It seems to be exactly what I am looking for... BUT... it is obviously a beta test version. While trying to do a "search" for the number for a standard part the application would not store the items I had already specified, and would crash when approaching the last item...

    Fastener Selection and Part Number Guide

    I am looking to obtain a fastener (screw, nut, washer, etc.) guide that lists not only the applicable dimensions (.086") and sizes (#2-56) but also the aerospace standard part numbers (MS..., NAS..., etc.). I have a few different versions from different companies but none cover the total range...
