    Future Fighters ?

    I believe that, just as they have since the 1960s, some politicians today are focused on creating 'final bosses' and enemies to manipulate public opinion and justify the necessity of AI in defense and flood the funds to defense.

    Future Fighters ?

    The distance between pilots in air-to-air combat is steadily increasing, driven by rapid advancements in AI and electronic systems. Looking ahead, it's likely that air combat will be dominated by unmanned fighters, coordinated from airborne command platforms. These autonomous systems can operate...

    Plate Bending Problem

    From the pic I assume the load is acting somewhere at the vertical midline of the door. If the latch is at the middle, top and bottom ends of the vertical mid-line would cause the most deformation. If the latch is at top of the right edge, the load acting bottom of the vertical mid-line would...

    Gas Speed under Labyrinth seal.

    Leakage speed at the labby seals are dependent to temperature, delta pressure between fwd-aft side, RPM, gas density, viscosity, closure at the seal rotor-stator interface. Didn't get the hazardous portion, "hazardous" is an adjective it's not a physical property.

    Tolerance stack up types

    1D and 2D stacks are the most common ones however, there are specific problems that requires to perform 3D stacks. Stack ups are usually made for room temperature but for the applications requires function in a wide temperature range, thermal effects on the geometry should be utilized in the...

    Nut is not self locking on the threads

    If there is resource, preparing 30 specimens for testing against the equation and refining the assumed parameters based on the normalized test results might work. Tackling with friction coefficients might be frustrating.

    Pull force on two cylinders

    Usually I use "press fit" equation from "Advanced Strength of Materials" textbooks and that equation yields the interface pressure. The interface pressure is one of the big contributors. If possible I prefer to use very similar materials with similar strength to avoid the complexity. For the...

    Should I include all the details on the parts drawing

    First of all, thanks again to everyone that helped me while figuring out the issue I had. I've talked with my supplier and just put a REF dimension for that feature. So I'm ok now. Hold on, this is not an answer for the question. Here nobody asks you how to design/dimension a part. The question...

    Should I include all the details on the parts drawing

    Hello everyone, I have designed a steel part for machining and while drafting it, I fully defined all the functional surfaces as precise as needed. Then moved into other features but there are some features that I don't want them to fully dimension and restrict with tolerances because these...
