CFD is often undertaken for rocket plumes, where condensed phase constituents can be present in addition to gaseous constituents. These types of simulations can become quite complex, including afterburning and thermal radiation , and (for example) ballistic missile launches are often detected by sensing hot rocket plumes.
The main flame deflector in the flame trench at Launch Complex 39B at NASA's Kennedy Space Center in Florida. It deflects the plume exhaust from NASA's Space Launch System rocket during launch. It features a new "steel plated" design and incorporates water pipes for sound suppression. [1]
Such a system will enable the spacecraft to loiter in orbit or on the surface of the Moon, potentially allowing a permanent lunar presence or supporting nuclear thermal propulsion. [ 18 ] Blue Origin is to lead the development of the lander, which is designed to fit in the 7 m (23 ft) payload fairing of the New Glenn launch vehicle in order to ...
The small particles in the expanding exhaust plume or "cloud" diffract sunlight and produce the rose, blue, green and orange colors—much like a dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow) – thereby making the twilight phenomenon all the more spectacular.
Shock diamonds are the bright areas seen in the exhaust of this statically mounted Pratt & Whitney J58 engine on full afterburner.. Shock diamonds (also known as Mach diamonds or thrust diamonds, and less commonly Mach disks) are a formation of standing wave patterns that appear in the supersonic exhaust plume of an aerospace propulsion system, such as a supersonic jet engine, rocket, ramjet ...
Sites for launching large rockets are often equipped with a sound suppression system to absorb or deflect acoustic energy generated during a rocket launch. As engine exhaust gasses exceed the speed of sound , they collide with the ambient air and shockwaves are created, with noise levels approaching 200 db.
Sonic booms are expected to ring out each time SpaceX returns a Super Heavy booster back to its Starbase launch site, as it did during the Flight 5 test of the Starship rocket system in October ...
Since this exhaust begins traveling in the "wrong" direction (i.e., outward from the main exhaust plume), the efficiency of the engine is reduced as the rocket travels because this escaping exhaust is no longer contributing to the thrust of the engine. An aerospike rocket engine seeks to eliminate this loss of efficiency. [1]
