Case IH 7140 rotary harvester with corn header with cutaway showing rotary threshing mechanism. Case IH axial-flow combines (also known as rotary harvesters) are a type of combine harvester that has been manufactured by International Harvester, and later Case International, Case Corporation, and CNH Global, used by farmers to harvest a wide range of grains around the world.
It used a unique "diagonal" compressor section that combined the features of both centrifugal and axial-flow compressor layouts for turbojet powerplants, but remained on the test bench, with only some nineteen examples ever produced. In the UK, their first axial-flow engine, the Metrovick F.2, ran in 1941 and was first flown in 1943. Although ...
November: The Junkers Jumo 004 axial-flow engine is tested. November: Gloster Aircraft Company's proposal for a twin-engine jet fighter is accepted, becoming the Gloster Meteor. December: Whittle's flight-quality W.1X runs for the first time. The Lockheed Corporation starts work on the L-1000 axial-flow engine, the United States's first jet design.
Von Ohain's design, an axial-flow engine, as opposed to Whittle's centrifugal flow engine, was eventually adopted by most manufacturers by the 1950s. [14] [15] A cutaway of the Junkers Jumo 004 engine. Austrian Anselm Franz of Junkers' engine division (Junkers Motoren or "Jumo") introduced the axial-flow compressor in their jet engine.
The basic principle of the engine was similar to the original Whittle engine developed in England, but Westinghouse’s use of an axial flow compressor, along with internal combustion chamber, were major advancements that led the way to a practical engine for aviation propulsion. (Earliest GE jet engines, based on the Whittle design and ...
The Pratt & Whitney J75 (civilian designation: JT4A) is an axial-flow turbojet engine first flown in 1955. A two-spool design in the 17,000 lbf (76 kN) thrust class, the J75 was essentially the bigger brother of the Pratt & Whitney J57 (JT3C).
The General Electric/Allison J35 was the United States Air Force's first axial-flow (straight-through airflow) compressor jet engine. Originally developed by General Electric (GE company designation TG-180 ) in parallel with the Whittle -based centrifugal-flow J33 , the J35 was a fairly simple turbojet , consisting of an eleven-stage axial-flow ...
The Metropolitan-Vickers F.2 is an early turbojet engine and the first British design to be based on an axial-flow compressor.It was an extremely advanced design for the era, [1] using a nine-stage axial compressor, annular combustor, and a two-stage turbine.
