Most Allied fighters at that time were powered by rotary radial engines (i.e., with the cylinders, arranged radially about the crankcase like the spokes of a wheel, rotating around a stationary crankshaft).
Below this, the sponge wall widens, with tubes arranged radially around the central atrial cavity, the so-called radial tubes.
Light brown in colour, it has finer and more densely arranged, radially aligned plates called septa and surface ornamentations.
What was being built in 1997 as my wellies slopped in the Greenwich goo was the result of this history: the largest membrane structure in the world, a polymer tent supported by tensioned cables arranged radially around a dozen 100m masts made of open steelwork.
The authors previously reported that the "Waterwheel cylinder," which consists of acoustic tubes arranged radially, approximates a soft surface cylinder.
The resulting three-dimensional model shows at least four projecting arms, arranged radially near the presumed interface with the 30S subunit.
