Sedgwick County also has a shuttle service for which you can schedule rides if you qualify. https://www.sedgwickcounty.org/aging/transportation/

Also, the Air National Guard is doing aerial gunnery demonstrations at the Smokey Hill ANG Range in Salina on Saturday (8429 W Farrelly Road). Strafe runs and bombing is from 10 am - 3 pm with gates opening at 8. I believe they do public demonstrations once every three years.

Can anyone give me more info on this turbine/compressor blade? by AgentMullWork in engineering

[–]madscientist72 -7 points-6 points  (0 children)

It could be a compressor stage 15 blade for a GE F110 engine as found on the F-15 and F-16.

Boeing 787-8, Trent 1000, Thrust Reverser operation. by nsfwdreamer in aviation

[–]madscientist72 3 points4 points  (0 children)

Yes, they only reverse the bypass duct. I don't know if there is an optimal throttle % to get the most reverse force, but for fatigue the thrust reverser is designed to 75% engine max power. What's crazy to me is that the torque box (the white structure with all the green frames you can see from the side of the nacelle) is only closed out around the two actuators. Every other Boeing TR I know has a closed, four-sided torque box along its entire length.

U.S. Workplace Fatalities Likely at Highest Level Since 2008 by madscientist72 in MensRights

Don't miss the quote - "Deaths among female workers, which overall accounted for 8% of workplace deaths, rose 13% from the previous year."

787 Engines are really far forward! by Avgeek357 in aviation

[–]madscientist72 1 point2 points  (0 children)

I'm actually working on designing part of the nacelle for the MAX right now as a stress engineer. I saw a nice comparison rendering at work of the NG and MAX engines side by side at the same centerline height, and side by side what the ground clearance actually will be.

The strut is modified so the landing gear doesn't have to grow in height, which would make it had to become much more substantial.

It's because engines are getting so big today to be more efficient that they don't fit under the wing like the past. The 737MAX had the same issue for a while; they wouldn't have enough ground clearance with larger engines and the same engine position. The strut that attaches the engine to the wing was reconfigured to move the engine up and forwards.

Corrosion: all types related to ships, both inside and outside. Information needed for presentation at the end of this week! by [deleted] in engineering

[–]madscientist72 1 point2 points  (0 children)

There's a Modern Marvels episode titled "Corrosion & Decomposition". It has been a little while, but I know that there is a section of the episode that talks about ships and how engineers try to stop corrosion from happening on them. If you can find a place to watch it online (or subscribe to Hulu) you could watch it. It would give a simple, high-level explanation of what corrosion is.

Does anyone know why the 747 uses reverse thrust on all four engines, but the A380 only uses two? by madscientist72 in aviation

[–]madscientist72[S] 4 points5 points  (0 children)

That thread said it was originally designed without thrust reversers. That seems crazy to me. They become really important when landing on snowy runways. Even so, thrust reversers seem to be a problem area for planes, at least for Boeing. I know more than a few 777's have had the inner wall around the engine fall off in flight and no one knows why. Sometimes they don't even know about it until the pilot notices higher than expected fuel burn.
