    CAD for wiring diagrams

    Onshape is free (your documents are public, subscribe for private) and does a great job with wiring (I left Solidworks and Fusion 360 for it). Dark Aero (excellent engineering, the opposite of our long lost muse Peter) uses it...

    X59 supersonic experimental aircraft

    Speaking of shock waves, during all of our trips to USAF O-Clubs, us Hornet drivers learned that the only thing faster than a Falcon driver bugging out of a position fight was them leaving the bar when the bill came due. Time to add a HBA supporter badge next to that "Well-Known Member" patch...

    X59 supersonic experimental aircraft

    1988-1992, F/A-18A, VFA-151, CV-41. 1984 BSAAE, The (pause) Ohio State University. No. Transonic shock waves were visible in numerous locations (e.g. on the canopy, literally inches away from your eyes) as you approached transonic, but there was no perceptible change in the ride, nor cabin...

    Anyone have a CNC in their shop ?

    You'll find similar folks not too far away at The Manufactory (makerspace just N of Cincinnati). They have two CNC mills (verticals) and a full weld shop (MIG, TIG, Oxy-Acetylene, spot, CNC arc plasma). Details here; www.themanufactory.us Several A&Ps are members there, plus ATPs, CFIs, etc...

    Horrible news from Vans Aircraft

    If only there was some way to repurpose/upgrade a terrestrial engine.

    CAD Software

    I've found Onshape's training videos to be efficient and effective. Best consumed on a dual monitor machine; one with the training material (link), the other with Onshape itself (second browser pointed to cad_dot_onshape_dot_com). Both are free, and the concepts you learn transfer to any 3D...

    Horrible news from Vans Aircraft

    Never underestimate the power of Wisconsin cheese fed engineers using Onshape (mobile, collaborative, version controlled, CAD).

    Pros and Cons on Composites vs Aluminum

    Wasting time on all that aeroenginumering just holds back genius. Just ask Raptor Aircraft.

    Horrible news from Vans Aircraft

    I'm sure they only wish them the best, but this is great news for Dark Aero.

    The Insidious Nature of Torsional Vibration

    Sorry if I picked the wrong thread - perhaps better in "Torsional Vibration and Resonance - Basic Theory and Issues". Could a dynamic spring rate (high frequency changes to electromagnetic field strength, perhaps scheduled by RPM, similar to PID tuning for motor control) help designers avoid TV ?

    Ross's Video on Dark Aero

    About 10K people per day turn 45 (USA). The merry-go-round keeps spinning long after our turn. Despite your fine efforts, their videos were muched needed eye bleach after that aussie killed all that corn.

    Ross's Video on Dark Aero

    One advantage they have is that any two of their combined ages sums to less than most of us. They see a long runway.

    EAA No Longer Has Free SolidWorks

    I'll take the under (on 3 years). Like everything online, this entire website was assimilated long ago.

    EAA No Longer Has Free SolidWorks

    Obviously their perogative (ending intake generation via free access - seems unwise), but if/when that happens, I leave with exported models on my local device, and hundreds of manhours of parametric CAD experience I wouldn't otherwise have logged, due to its pervasiveness (mobile means I can...

    EAA No Longer Has Free SolidWorks

    Dark Aero (YouTube) moved from SW to Onshape (I did too). It's free, mobile (kids live there), collaborative (comments, notification, versions, screen sharing), and builds on your SW knowledge.

    Best CAD tool for modeling and simulation on for a homebuilt.

    Human nature makes CAD resistant to consolidation (a very fragmented market). An impressive team (DarkAero) landed on Onshape. Among their many excellent videos are several focused on modeling and analysis (which the OP inquired about, and likely would enjoy). Onshape's "Part Studio" (top...

    After their page loads, hit your refresh button, then hit it again while it's still an "X" (to stop hidden Javascript from running). Timing will vary (typically < 2 seconds) depending on your PC.

    Crashes in the News - Thread

    I was aware. Like it or not, writing checks reduces scrutiny and increases access. CAF (and relevant other entities) could easily release their financial records and disabuse us of our Pay-to-Play (fly) theory. I saw lots of pilot attrition going through adversarial taxpayer-funded flight...

    Crashes in the News - Thread

    The target aircraft in the video you provided was undoubtedly visible to the pilot the entire time. It just takes a little cross-control to move a canopy rail out of the way while managing closure and angles during a join-up. The camera's location (offset ~5" from the pilot's left eye) denied...

    Parts Wanted Wanted: CAD Designer

    I highly recommend Onshape (free, platform agnostic). I'm the poster boy that any fool can do it (learned CAD at age 60). Since it runs on your phone, young people love it (check out your local makerspace, library, user groups, YouTube, etc.).
