In the supersonic stream, nevertheless, the stress disturbance can not propagate upstream. Thus, if the fluid eventually reaches the object it strikes it as well as fluid is pressured to vary its Houses – temperature, density, force, and Mach quantity—in an extremely violent and irreversible trend called a shock wave. The presence of shock waves, along with the compressibility consequences of significant-circulation velocity (see Reynolds quantity) fluids, is definitely the central distinction between the supersonic and subsonic aerodynamics regimes.

如果通入過量二氧化碳，沉澱會重新溶解，因爲碳酸鈣會轉化為可溶的碳酸氫鈣。

This reduction contributes to considerably less gas consumption, comprising a considerable chunk of operational expenditures, without the need of compromising on the load-carrying potential of your aircraft.

Carbon dioxide fuel that comes off of dry ice is so cold that when it mixes with air it cools the h2o vapor inside the air to fog, which seems like a thick white smoke. It is often Utilized in the theater to create the appearance of fog or smoke.

二氧化碳是一種酸性氣體，因此可以跟鹼反應。例如二氧化碳跟氫氧化鈉反應：

Since GKN could not generate the titanium honeycomb internal walls for the thrust reversers speedily enough, Boeing switched to the composite section made by Spirit to deliver forty seven MAXs each month in 2017.

Boeing confronted lawful and fiscal repercussions, as no deliveries on the MAX may be created whilst the aircraft was grounded, and airlines canceled more orders than Boeing manufactured through this period. Boeing found international item debris in the gas tanks of 35 of 50 grounded 737 MAX aircraft that were inspected and experienced to check the remainder of Lease the 400 undelivered planes.

The wellbeing-monitoring process of this connected Airbus aircraft allows for issue-solving in actual time, presenting superior trustworthiness though reducing routine maintenance downtime.

NASA explores the not known in air and Room, innovates for the benefit of humanity, and evokes the entire world through discovery.
