An interdigital transducer (IDT) is a device that consists of two interlocking comb-shaped arrays of metallic electrodes (in the fashion of a zipper). These metallic electrodes are deposited on the surface of a piezoelectric substrate , such as quartz or lithium niobate , to form a periodic structure.
Just Read the Instructions (I) SpaceX's first ASDS was named Just Read the Instructions (JRTI). Converted from the existing Marmac 300 barge, JRTI served as a testbed for just two landing attempts, SpaceX CRS-5 and SpaceX CRS-6, the latter of which ended with the booster toppling over and exploding, damaging JRTI beyond repair on 14 April 2015.
An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode . Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [ 1 ]
The S2 9.2 is a recreational keelboat, built predominantly of balsa-cored fiberglass, with teak wood trim. It has a masthead sloop rig, a raked stem, a slightly reverse transom, a skeg-mounted rudder controlled by a wheel and a fixed fin keel.
A tunnel hull is a type of boat hull that uses two typically planing hulls with a solid centre that traps air. This entrapment then creates aerodynamic lift in addition to the planing (hydrodynamic) lift from the hulls.
Pride of Hull was designed as two ships in one, both a car ferry and a cargo transporter, with three large freight decks, loaded by a single stern door and a car deck, on deck 7, loaded via a side ramp. She is 215.05 m (705 ft 7 in) long with a beam of 31.85 m (104 ft 6 in) and a draught of 6.04 m (19 ft 10 in).
Her hull was built of welded steel plates. She was 225 feet 11 inches (68.86 m) long at the waterline and 240 feet 1 inch (73.18 m) overall, with a beam of 42 feet (13 m), and a draft of 15 feet (4.6 m). She displaced 2,260 tons fully loaded. [2] As originally built, Apache had two controllable-pitch Kort-nozzle propellers for propulsion.
