    Insulation on Aircraft

    WKTaylor , sorry yes, I am talking about Solimide. I have been told by some insulation providers that a lot of people use Solimide but that Solimide or Polyimide foam is used in the bagged insulation blankets by some suppliers who do really not understand the concept of insulation. The use of...

    Insulation on Aircraft

    Hi, I am wondering if anyone out there has used SILAMID for insulating narrow body aircraft? I might be spelling it wrong, but if you have, what can you tell me about it in terms of material specifications, weight, flammability, etc.? Did it save you weight compared to other insulation? I...

    which is the Best Course For Fatigue and Damage Tolerance learning?

    Just wanted to ask experienced F&DT engineers out there if they have a good course they recommend for an engineer wanting to learn more about F&DT. Which do you think is the best and is dedicated to training an engineer to immediately jump in and start writing reports related to Fatigue and...

    CL-650 Aft Pressure Bulkhead, Design wants to attach lavatory cabinets to it.

    I want to thank all of you for your in-put into this matterm, its been two months of explanation and still my manager and director are refusing to listen to me and have basically lied (talked the position into their favour) to the company working with Transport Canada about how this is really no...

    CL-650 Aft Pressure Bulkhead, Design wants to attach lavatory cabinets to it.

    FastMouse Thank you for taking the time to write your comments. I am not a DT expert by any means, but in my limited knowledge I questioned the designer how inspections would take place since there would now be several layers of metal and places where all possible cracks would not be visible by...

    How Many Test samples would be acceptable for Company Allowable Data used on STC projects

    SparWeb - Thank you for your response and the explanation. I have looked at Chapter 9 of the MMPDS a little, which is why i was wondering about sample size. some of the charts express speciman numbers of 10 to 10,000. I also read somewhere that in order to make 95% or 99% accuracy that you...

    CL-650 Aft Pressure Bulkhead, Design wants to attach lavatory cabinets to it.

    I was asked to Analyze an aft Lavatory compartment that is being attached to the Aft Pressure bulkhead for a CL-650. This is my first time seeing it today and basically the lateral brackets (see attached photo) use the existing holes of the support structure to attach. To me this is a major...

    How good is Cosmos/Simulation at analyzing Composite Honeycomb panels

    thanks Tmoose, I still have not even been given access to the software yet, but when i do, is there a training that you think is best. So far from all the youtube videos i have seen, it is a VERY different user interface than i am used to. Also, do you know if, once the analysis is run, does...

    How Many Test samples would be acceptable for Company Allowable Data used on STC projects

    I am currently working as the only stress engineer in a large organization and this is the first time in many years that I am writing test plans for latches/hinges/inserts into the typical honeycomb panels we will be installing them into. This will become part of the analysis handbook that is...

    How good is Cosmos/Simulation at analyzing Composite Honeycomb panels

    Hi, I am working for a company that builds Aircraft interiors fabricated solely from Fiber/Aluminum Honeycomb panels. They are refusing to purchase FEMAP or Patran but instead want the Stress Engineers to use Simulation/Cosmos as it is free with their SolidWorks packaging. I have been reading...
