Jul 19, 2015 · Usually simply abbreviated as a RUD, and also sometimes expanded as Rapid Unplanned Disassembly, and being a way of understating that a rocket exploded. I saw it attributed recently to Elon Musk, but although he has popularized the phrase among the public, when he mentioned it once in a speech I saw he simply said it is how the engineers on the ...

Feb 26, 2021 · As a result the RUD trim will be saturated (Left or Right 6°). Thus the aileron trim is then commanded in an attempt to counter the existing β. However the aileron trim is a function of a flight control gain (GALR) which was designed as a function of Mach, assuming a nominal entry alpha to mach profile.

Nov 18, 2023 · SpaceX Starship Ship 25 launched and managed a successful separation from the booster and reportedly made it into space before the autonomous flight termination system activated, destroying the veh...

This generic question is answerable. They blow up, aka rapid unplanned disassembly (RUD) but due to a large number of causes. Or parts fail slowly and the vehicle eventually loses structural integrity. There are lots and lots of things that can go wrong on objects in space.

Sep 2, 2016 · But with the payload in place, RUD during the test fire is hardly a better outcome than RUD during launch. I would also expect there to be at least some "bad luck" failure modes that occur only rarely, and are difficult to detect before they do occur (meaning that a test fire before launch effectively just doubles the risk of those failure modes).

Jan 20, 2020 · Often the RUD comes later (see the Soyuz inflight abort - issue, followed by escape, followed by issue escalating into RUD). This would cover anything from a pump failing, engine gimbaling failing, unplanned engine shutdown, inability to stage etc etc etc. $\endgroup$

Sep 1, 2022 · If they went ahead and launched anyways with E2058 running, it may pose a hazard to the other three functioning engines as RUD and associated debris may impact the engine block / SRBs (potential Challenger-like failure mode) $\endgroup$ –

The CRS-7 in flight RUD was thought to be a strut holding the COPV failed and it broke off a pipe which vented the pressure into the tank, bursting the LOX tank. Share Improve this answer

Apr 13, 2019 · Not a good idea for amateurs; it can kill you without you realizing you're dying: 10–20 ppm can cause mild irritation of the nose and throat, 25–50 ppm can cause edema leading to bronchitis or pneumonia, and levels above 100 ppm can cause death due to asphyxiation from fluid in the lungs.

Jul 9, 2015 · ..what reason is there for having the engine at the bottom, .. For the fundamental logical flaw in the desire to move the engines, please see this answer of Russell Borogove - it comes down to The Pendulum Fallacy (the exact same fallacy I made when considering other reasons for 'engines at bottom of stack').
