The aft pressure bulkhead is the white circular component; its web-like structure led a NASA technician to attach a large model spider to it for comedic effect. The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. [ 1 ]
Super Heavy is 71 m (233 ft) tall, 9 m (30 ft) wide, [8] and is composed of four general sections: the engines, the oxygen tank, the fuel tank, and the interstage. [9] Elon Musk stated in 2021 that the final design will have a dry mass between 160 t (350,000 lb) and 200 t (440,000 lb), with the tanks weighing 80 t (180,000 lb) and the ...
The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter .
The term was later applied to other vehicles, such as railroad cars, hopper cars, trams, automobiles, aircraft or spacecraft, as well as to containers, intermediate bulk containers and fuel tanks. In some of these cases bulkheads are airtight to prevent air leakage or the spread of a fire.
Oil tankers generally have from 8 to 12 tanks. [1] Each tank is split into two or three independent compartments by fore-and-aft bulkheads. [1] The tanks are numbered with tank one being the forwardmost. Individual compartments are referred to by the tank number and the athwartships position, such as "one port", "three starboard", or "six ...
The tanks are normally divided by a centreline liquid-tight bulkhead; by this feature, together with the chamfered upper part of the tank, the free liquid surface effect is reduced and thus the virtual rise of the Centre of gravity and the stability is increased.
