The shape of the bubble is defined in terms of axial ellipticity, as determined by an energy balance on the gas jet enclosed by the expanding envelope.
A jet-fueled plane flies the envelope across the country.
Validated engineering tools for calculation of flammable envelope size and hydrogen jet flame length are of importance for calculation of safety distances.
Repeat the steps above to open the envelope in this hotter steam jet.
The view providing the most complete envelope, with the highest-velocity regurgitant jet, was used for measurements.
"Grab the stick of the fast and nimble Western Besra training jet and push it to the edge of the envelope.
If the relativistic jets are too brief and fail to penetrate the stellar envelope then a low luminosity gamma-ray burst may be produced and the supernova may be sub-luminous.
The action squeezes out a jet of water that spurts so fast it opens up a small envelope of space in its wake.
The infall of this material into a black hole drives a pair of relativistic jets out along the rotational axis, which pummel through the stellar envelope and eventually break through the stellar surface and radiate as gamma rays.
Bloodhound SSC is aiming for over 1,000mph, which is faster than any jet fighter has ever been at ground level, so we're taking the engine outside its design envelope.
