The sleek, backswept wings, the double bubble of the canopy perched almost too far up on the aircraft, its sleek, aerodynamically sound nose.
Dubbed "double bubble", the roof featured slightly raised sections above each seat to accommodate usage of helmets, a throwback to its intended purpose.
Oop, double bubble: Sylvan Ebanks-Blake comes on for Kevin Doyle.
You drew the plans, and then got in ten thousand lads on time-and-a-half and double bubble at weekends.
In a standard double bubble, these surfaces are patches of spheres, and the curve where they meet is a circle.
Based on this lemma, Michael Hutchings was able to restrict the possible shapes of non-standard optimal double bubbles, to consist of layers of toroidal tubes.
Additionally, Hutchings showed that the number of toroids in a non-standard but minimizing double bubble could be bounded by a function of the two volumes.
In particular, for two equal volumes, the only possible nonstandard double bubble consists of a single central bubble with a single toroid around its equator.
It would take more than a builder's lorry and a bunch of willing lads on double bubble.
It featured the typical Zagato cues: the double bubble on the roof and the large rear intake of the engine, very similar to supersonic planes' turbine.
