Random information on the term “SST”:
The SST (Sea Scout Twin) class of non-rigid airship or “blimp” was developed in Great Britain during World War I from the earlier SS class airship. The main role of these craft was to escort convoys and scout or search for German U-Boats.
Designs were submitted in 1917 for a twin-engined SS class airship, the idea being that should there be an engine failure, the craft would not be rendered helpless and therefore less likely to be lost. The first submission was a failure, but the second showed promise and was put into production. Designated the SST class, the first of 13 examples entered service in June 1918, and the last in May 1919, three of which, S.S.T.9, 11 and 12 were purchased by the US Navy.
The SST used a larger 100,000 cu ft (2,800 m3) envelope than any of the other SS class types, and was equipped with a streamlined and waterproofed car that could accommodate a crew of five. Two 100 hp (75 kW) Sunbeam or 75 hp (56 kW) Rolls-Royce Hawk engines were each mounted on a gantry either side of the car, and drove 9 ft (2.7 m) diameter four-bladed propellers in pusher configuration. At 57 mph (92 km/h), the SSTs had a greater top speed than all other SS class types, had the highest useful lift, and could stay airborne for up to two days. They were also cheaper to produce and easier to handle than the successful C Star class airship. Three SST were transferred to the Navy in June 1919. No Serial Numbers were assigned and there is no evidence they operated by the Navy. The 3 SST’s were transferred to the Army in 1919-1920. The Army operated the SST’s until late 1923 or early 1924.
Random information on the term “JET”:
A jet engine is a reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. This broad definition includes airbreathing jet engines (turbojets, turbofans, ramjets, and pulse jets) and non-airbreathing jet engines (such as rocket engines). In general, jet engines are combustion engines.
In common parlance, the term jet engine loosely refers to an internal combustion airbreathing jet engine. These typically feature a rotating air compressor powered by a turbine, with the leftover power providing thrust via a propelling nozzle — this process is known as the Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines which were relatively inefficient for subsonic flight. Modern subsonic jet aircraft usually use more complex high-bypass turbofan engines. These engines offer high speed and greater fuel efficiency than piston and propeller aeroengines over long distances.
The thrust of a typical jetliner engine went from 5,000 lbf (22,000 N) (de Havilland Ghost turbojet ) in the 1950s to 115,000 lbf (510,000 N) (General Electric GE90 turbofan) in the 1990s, and their reliability went from 40 in-flight shutdowns per 100,000 engine flight hours to less than one in the late 1990s. This, combined with greatly decreased fuel consumption, permitted routine transatlantic flight by twin-engined airliners by the turn of the century, where before a similar journey would have required multiple fuel stops.
