Collection of control yokes at Boeing Future of Flight Museum: 747, 707, B-29, Trimotor.The former two yokes are W-shaped, while the latter two are circular. The cockpit of Concorde, which has an M-shaped yoke mounted on a control column The cockpit of an Embraer ERJ with an M-shaped yoke "W"/"U" style yoke in a Cessna 152 light aircraft, mounted on a horizontal tube protruding from the ...
It is the first tessellation in the demihypercube honeycomb family which, with all the next ones, is not regular, being composed of two different types of uniform facets. The 5-cubes become alternated into 5-demicubes h{4,3,3,3} and the alternated vertices create 5-orthoplex {3,3,3,4} facets.
An altazimuth mount or alt-azimuth mount is a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes – one vertical and the other horizontal. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument.
A honeycomb-shaped structure provides a material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties. [1] Man-made honeycomb structural materials are commonly made by layering a honeycomb material between two thin layers that provide strength in tension. This forms a plate-like assembly.
Because heat-resistant titanium is hard to weld and difficult to work with, welded nickel steel was used for the Mach 2.8 Mikoyan-Gurevich MiG-25 fighter, first flown in 1964; and the Mach 3.1 North American XB-70 Valkyrie used brazed stainless steel honeycomb panels and titanium but was cancelled by the time it flew in 1964.

The first utility pouches in production had additional belt attachments for high mounting, similar to the ammunition pouches of the 1937 pattern web equipment or 44 pattern. Later produced PLCE webbing of the 90 pattern incorporates ambidextrous yoke fittings and the standard PLCE webbing belt attachments (see below).
The Voronoi cell of the E 7 * lattice is the 1 32 polytope, and voronoi tessellation the 1 33 honeycomb. [3] The E 7 * lattice is constructed by 2 copies of the E 7 lattice vertices, one from each long branch of the Coxeter diagram, and can be constructed as the union of four A 7 * lattices, also called A 7 4 :
The alternated cubic honeycomb is one of 28 space-filling uniform tessellations in Euclidean 3-space, composed of alternating yellow tetrahedra and red octahedra.. In geometry, a convex uniform honeycomb is a uniform tessellation which fills three-dimensional Euclidean space with non-overlapping convex uniform polyhedral cells.
