9 gen 2024 · I agree with @phil1008’s answer, but will amplify it to “YES, always”.Shadows may be difficult to detect if the contrast is low (for instance, added light from the exhaust itself) but light passing around the exhaust will always be brighter than light which has passed through the exhaust unless the exhaust is completely uniform and has exactly the same refractive index as the ambient air.
Also when the rocket is turned from horizontal to vertical at the launch pad. If the launch pad is evacuated just before fuelling, the covers should be removed before. If launchpad security regulations allow human access to the nozzles of a tanked rocket, they may be removed short before launch. $\endgroup$ –
19 apr 2020 · The red color makes it easier to detect spills. In Canada, agricultural diesel is dyed green, so if you buy it and use it in your diesel car, the cops can catch you by the green exhaust. (Taxes are very different on the two types of diesel). So maybe Rp-1 is died red so if you try using it in your rocket, with the agricultural licensed RP-1 you ...
7 giu 2016 · So to answer your question directly, not counting the OMS propellant as per the specifics of your question, the total mass of all propellants of the SRBs (stage 0) and the external tank (stage 1) was at launch of the STS 1,735,601 kg (3,821,722 lb). The solid rocket boosters provided roughly 83% of liftoff thrust for the Space Shuttle and were ...
10 gen 2015 · 16. The flame exiting the space shuttle main engine is obviously transparent. But, you can't see objects through either the Saturn V booster flame or that of the space shuttle solid rocket boosters. Is it that they are actually just as transparent as the hydrogen-fueled flame of the shuttle main engines, but emitting so brightly in visible ...
17 feb 2018 · Watching a documentary on the Viking missions, I noticed the launcher had a small red tank/rocket attached to one of the solid boosters. It struck me as an odd feature/placement, as I thought you'd want your rocket to be balanced as symmetrically as possible. I've also not noticed this on other launchers.
Red Rocket-X为其RedCine-X 33 Full Debayer编辑工具的视频编解码进行了增强，可以看做是专门的视频编解码加速卡，但不知道其芯片是采用FPGA，或者定制的ASIC。. 目前状态：当前Nvidia、AMD的GPU性能已经大幅提升，Red公司已经终止了Rocket-X产品线，并在公司主页推荐Nvidia ...
29 nov 2016 · The vapourisation of the LOX takes heat away until a pool of liquid begins to form. When enough liquid has collected, filling steps up to a fast rate until the tanks are nearly full and the slow rate is reestablished to top them off. From then on, until three minutes before launch, the level is replenished as the volatile LOX continues to boil ...
16 nov 2014 · If different stages have different colors it may be easier to determine whether they have separated or not. But it does not explain, why some Progress rockets (which have the same "ancestor" as Soyuz) are white. Danger sign. Orange parts are colored that way because some of them fall down to ground and may contain remainders of a highly toxic ...
13 lug 2020 · 1. @Aeronautic Freek It is unlikely that there is a single optimum shape. If there were, all engines would use it. Thrust chamber design, like the design of most complex devices, is driven by many tradeoffs. Of course thrust depends on the shape, a poorly designed chamber would give minimal thrust. – Organic Marble.
