Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several rows of airfoils to achieve a large pressure rise, making them complex and expensive relative to other designs (e.g ...
In the axial compressor the air flows parallel to the axis of rotation. Axial compressors are made to be multi-staged. A stage consists of a row of rotating blades called the rotor, which are connected to the central shaft and a row of stationary or fixed blades called stator. In axial flow compressor, the air flows from stage to stage.
The engine had four basic components: a single stage centrifugal compressor with double-sided impeller, a single straight-through combustion chamber, a single stage, axial flow turbine and a convergent propelling nozzle attached to a jet pipe. The shaft connecting the turbine to the compressor was made as short as possible to avoid whirling. [4]
In total loss, endwall losses form the fraction of secondary losses given by Gregory-Smith, et al., 1998. Hence secondary flow theory for small flow-turning fails. Correlation for endwall losses in an axial-flow turbine is given by: ζ = ζ p + ζ ew ζ = ζ p [ 1 + ( 1 + ( 4ε / ( ρ 2 V 2 /ρ 1 V 1) 1/2) ) ( S cos α 2 - t TE)/h ]
A dual-spool axial-flow compressor. Many turbofans have at least basic two-spool configuration where the fan is on a separate low pressure (LP) spool, running concentrically with the compressor or high pressure (HP) spool; the LP spool runs at a lower angular velocity , while the HP spool turns faster and its compressor further compresses part ...
A Velox boiler is a turbocharged, forced circulation, water-tube boiler which utilises an axial flow compressor and a gas turbine.Velox (Latin: "fast") boilers, also known as Velox steam generators, were developed in the early 1930s by the Brown Boveri Company (BBC) of Switzerland. [1]
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 engine's design is unusual; the core flow path is reversed twice. Aft of the fan, the axial compressor has five stages, after which the gas path progresses to the aft end of the engine. There, it is reversed to flow through a centrifugal compressor stage, the combustors and then the turbine stages.
