A section view will also explicitly define which side the cut out is facing.
So, when (not if) the mistake is made by production, you can point at the section view and show it to your boss.
No. One Raptor engine (from an earlier test flight) was re-used in the booster that was recovered.
The Upper Stage - the one that failed on the Jan 16 flight - was a revised design from a style used successfully before, but it (the upper stage) had not been flown as a unit before before.
I...
That debris field (Sept 2018) from the upper stage Unplanned Rapid Disassembly (Outside Operational Planned Scenario) Event is strikingly similar to the Jan 16 upper stage debris field photographed from below.
Cue FAA hysteria and increased delays.
What would you expect to learn from vacuum box testing? Only that no pin hole leaks exist through the weld?
Dye pen test would tell you more actually. And then an RT.
Why RT? Is the geometry unsuitable for UT?
Oh, by the way. What material, what pressure, what fluid, what criteria...
We are now approaching 20 Dec, 30 days after this plea.
(Robt wonders if the interview was successful in revealing the qualifications for a Senior Reliability Engineer at SpaceX.)
Why is the "trailer skin (?) thermal expansion" causing instrument measurement difficulties?
Seems the instrument would have to be mounted on shock-proof or very resilient mounts to avoid damage while the trailer is being pulled, when the trailer frame itself is bent and twisted loading and...
On two levels, it can hardly be otherwise: A welder cannot "be qualified" on a WPS test weld if that WPS itself is not yet qualified.
On the other hand, should YOU (your company) always chose your best welder (of those available) to make the certification welds for a new WPS?
Your "best...
Rational limits apply "first".
Example:
- Dye Pen exam or UT exam MUST WAIT until the weld zone has cooled down to near-room-temperature. The dye and UT lubricant/sound seal goop needs time on a relatively cool surface to soak, to not be burned off by a hot weld zone.
- VT? Often, can be...
I regularly use 6 and even 8 inch NPT threaded fittings on temporary lube oil pipe assemblies for flush fittigns and lineups. But those are temporary use, low temperature (60 to 150 deg F) and low pressure assemblies.
Every threaded fitting MUST BE allowed to be screwed tight, then not...
Purchased a new NiCd razor. It has an old-style external (1.5 volt DC wall plug-in/cheap Chinese) charger/inverter.
No apparent "controller" or regulator like the more modern LiOH batteries and regulators.
Will I gain anything useful by fully discharging it to 0.0, then recharging? Or just...
Liability and the "pursuit of accountability" might be difficult:
"Pemex took full ownership of the Deer Park refinery in early 2022, acquiring Shell SHELL's stake in a refining joint venture. Mexico had acquired the facility to become more self-sufficient in gasoline and diesel."
The Mexican...
An open question about pipe supports in that 3D image. How is the sliding small pipe support under the 1 inch (1/2 inch ?) pipe coming off the bottom of the large elbow expected to "only carry" the small weight of the 1 inch pipe?
Would not the massive weight of the large pipe and its...
I was told on a different thread on www.freerepublic.com that the excess fuel was burning off while being "drained" out the bottom of the stage by gravity after landing (being caught in the twin arms). Disconcerting to see open flames after a landing - Certainly NOT what I expect after an...
I share Little Inch's reservations about the access to the large flange nuts and bolts for removal (of the bolts/studs) and torqueing of the nuts. (Add access and torqueing of the small flange nuts and fasteners too.) To resolve assembly and maintenance concerns, move the fitting out towards...
