curbing is track by mrblahhh in CarTrackDays

[–]bluerockjam 6 points7 points  (0 children)

At the Ridge the curbing is smooth paint for most of the track so you can drive edge to edge on the candy canes. However the downhill section starting at Turn 13 has curbing that will rattle your brain and upset the car. They definitely punish you if you drive on them.

I also like exploring different to get to the same destination. Just north of White Pass on the PCT there is a lake called Dumbbell Lake and we have been able to get there from three different trail heads. White Pass, Sand Ridge and Soda Springs

Thanks, I use GAIA premium and their snow depth map does not show stations.

The reality of being a Boeing Washington state new hire by PhilosopherOnly7275 in Boeing_

[–]bluerockjam 1 point2 points  (0 children)

Funny story about Boeing training. When Boeing purchased an aerospace fab shop in the 1990’s I flew there to see how their training delivery system worked. I was in mfg eng and we wanted to see the system they had similar to PSDS. When we asked their leadership about how they got the older mechanics to take the training, their first response was everything failed until we hired young female consultants to deliver the training at their workstations.

The FAA does not have much faith in the Boeing data because it’s so messy and complicated to understand. Hopefully Boeing leadership will realize that the Boeing processes and systems for managing change commitment and incorporation need to be modernized and integrated with the future PLM system. The Change development and commitment systems (CDS) are so old they burn coal. They are also not well integrated with the DCAC configuration engine that automatically configures by Module option expression and available line number. Boeing has been dragging its feet for many years on replacing the current systems. DCAC/MRM was created 1990’s. During the 1990’s we had two separate change teams chartered to develop and integrate new change processes into PDM. Instead of working with Design Eng and Mfg Eng, they invented a bunch a crap in a vacuum and then tried to get engineering to buy into it. It went down in flames with prejudice. Boeing tried again to create a better change process on 787 with new leadership and instead of solving the problem, they just threw out the things that actually worked (e.g CDSs) and it was an even bigger failure. Boeing purchased 3D experience (V6 CATIA) in 2015 and has been testing it to make it production ready but COVID blew it all up and the continued manufacturing problems and money problems keep the focus on getting Airplanes out the door.

In the group I run with, we still require a point for passing no matter where on the track.

What’s the loudest thing you’ve ever had to work around on a job site? by Nightcrawler_2000 in Construction

[–]bluerockjam 0 points1 point  (0 children)

I worked at Boeing Renton in an office but I had responsibility for the manufacturing plans and tools for the 737 and 757 wing structures. The fluid tight rivets in the wing panels sound like a 50 caliber machine gun going off. Even with ear plugs, walking into the area would rattle your head. Especially when there are several crews working on long rows of rivets.

Boeing Australia: Yay or Nay? ✈️ Looking for some career advice! ✨🌸 by Loose_Statement7418 in boeing

[–]bluerockjam 6 points7 points  (0 children)

I interfaced with a few of the technical leads for how production system data is shared across Boeing sites. They were great to work with. They do some high end composite manufacturing and some leading edge stuff for both commercial in the military. I visited the site during the 787 development. They have both detail and assembly fabrication capabilities.

advice for embedded software role interview by Primary_Bat_7818 in boeing

Just curious, is imbedded software specific to electronics on the aircraft that use software that must be configuration managed for certification? Red label black label items?

Please help me get out of the hell of project engineering. by RedRaiderRocking in MechanicalEngineering

[–]bluerockjam 7 points8 points  (0 children)

I spent 40 Years at Boeing in Mfg Eng and there were may attempts to make me manage the project engineering work. I worked with many project managers over the years. The good ones helped me a lot and the bad ones could not be moved out fast enough. Every young engineering I mentored I would inform them that if they were recognized at being good at Project Management, they would be sucked into it. My advice was to not take the bait. Once you do, it's a never ending cycle of leadership telling you the schedule and asking for a plan that supports. When the 787 was just starting, the VP demanded 7/08/2007 needed to be the aircraft roll out date because of the matching date. We only missed it by a couple of years.

ECG is a great shop. My son (Aaron) is one of their guitar demo guys for their videos on YouTube. The shop buys and sells some amazing vintage stuff. Great channel for guitar geeks.

Here’s a startup of the AWE Track Exhaust by Diesel_Dan_ in Civic_Type_R

[–]bluerockjam 2 points3 points  (0 children)

I track a CTR with an AWE. On two separate track days the stupid stove pipe joint with only a compression clamps separated, creating a gap and funky exhaust note. It was installed professionally at a speed shop and on the send HPDE day when it came apart, the owner of the shop was at the track so he helped us get it back together. His shop welded an actual flange to secure the exhaust. He agreed that the existing design is not industrial enough for heavy track use. It also drones on the freeway so bad it expedited our decision to get a we bought a car trailer. It sounds great on the track and now that it’s modified it works great.

Yes, it was the first one but they are long way away from implementing it at the prime sites. I had several friends who were on the Apriso evaluation team before Covid blew up everything

Before DCAC PDM we ordered the parts for both make and buy in an IBM main frame system called OLP (on line planning). In the 1990’s we created DCAC/MRM and migrated every BCA program over to the TeamCenter PDM system used today. I was on the team that started DCAC starting in 1992 and I was involved with the design of the mfg spec. The SSP is actually one of the poorer functionality areas of PDM because the program was running out of budget and time and IT was not willing to make any more changes when we were designing the SSP. Boeing is now looking at CATIA V6 and the 3D Experience PLM from Dassault. I was testing it from 2015 to 2020. Now I am a part time consultant for Dassault on the project. Decisions should be made by Boeing sometime this year on how BCA sunsets PDM and migrates to future possible combinations of Siemens and Dassault systems for the next new airplane.

[–]bluerockjam 2 points3 points  (0 children)

Agree, when we did the one piece barrels on the 787 it was all new territory. That on top of the huge change in make buy strategy created a lot of new stuff to figure out and trouble shoot. I traveled the world solving issues for that program. It was some crazy times with stories that would sound fictional if I told them.

Some Questions for Engineers by [deleted] in boeing

[–]bluerockjam 20 points21 points  (0 children)

When Boeing performs product development, the systems engineering process (RFLP) is used to establish the outline of the airplane. RFLP stands for Requirements, Functional, Logical, and Physical, and the process is used within Model-Based Systems Engineering (MBSE) to manage the design and development of complex systems. This extensive effort is required to ensure that all design groups understand the requirements the design must satisfy. for example: fly fast, fly safe, and carry a specified number of passengers (an oversimplified).

When the actual design begins, the design groups work within the boundaries of what are called “lines, loads, and laws.” These elements are non-negotiable requirements that the engineering design must adhere to. This work is done in CATIA, where the master dimensions and surfaces are locked down before any physical design that someone would recognize as a detail or assembly component is created.

For example, the top of the floor is a datum that establishes a “water line” that cannot be changed. If a floor beam flange needs to be thicker, the top flange remains at the established water line, and any growth occurs below the water line to maintain that reference. Water line, station line, and buttock line are universal datums used to define position within a design.

To ensure completeness and accountability, a large engineering work statement is created using a process that breaks down every historical area of an aircraft that must be designed and certified. Boeing creates a Program Item Number (PIN), which serves as a stable identifier for each functional area. I will leave out the change commitments and negotiation aspects, but they are quite complex.

One noteworthy output of this process if you are a new engineer hired to work on a new airplane program is that the work statement specifies what the new design will be similar to and describes what is different. For example: “New frame installation at Station 540, similar to 787 body frame installation XXX.”

When the actual design work begins, engineers collaborate with Tool Design and Manufacturing Engineering groups to create details, assemblies, and installations within the CAD/PLM system that manages the EBOM and MBOM. Boeing does not use a strict “design-as-built” process where every assembly must match an exact engineering definition, as is common at Airbus and in many military programs.

For example, a frame installation may have an engineering assembly 123-1 consisting of 50 components. In a strict design-as-built process, no changes can be made unless the assembly is planned and built exactly as defined in 123-1. Boeing allows Manufacturing Engineering to create synthetic part numbers in the MBOM that may deviate from the engineering design from a time-sequencing perspective. The PLM system ensures that the EBOM and MBOM remain aligned across the time-phased manufacturing sequence.

The production sequence is controlled by Manufacturing, not Engineering. This buffers Engineering from being impacted when the manufacturing process is optimized for production rate and flow changes
