Other key features include: a highly efficient 27:1 pressure-ratio high-pressure compressor
; a low emissions combustor; and lightweight and durable ceramic matrix composite material used in the combustor and turbine.
Mehrer Compression has unveiled its latest product innovation -- the new high-pressure compressor
The Pearl 15 has a completely new engine core, with a 10-stage high-pressure compressor
, and a two-stage high-pressure turbine with enhanced aerodynamics and blade cooling.
Pratt has said the problems, which resulted in some A320neo aircraft being grounded and halted deliveries, are caused by an engineering change to the "knife-edge seal" in the high-pressure compressor
near the rear of the engine.
Safran Aircraft Engines is a developer and producer of the high-pressure compressor
, the combustion chamber, the high-pressure turbine, the gearbox, the FADEC system.
The company will also be demonstrating the Belliss and Morcom WH35 high-pressure compressor
; one of the most power efficient PET compressors available on the market today.
The effect of this can be seen in Figure 1(a) where the work required by the high-pressure compressor
increases and consequently, the system COP decreases.
The other solution was to buy a dedicated high-pressure compressor
that retails for S3.000+ and needs a lengthy break-in procedure before it can be turned loose II was the fastest way to fill a tank, but certainly not the cheapest!
For high-pressure compressor
trains of more than 5 MW, gas turbine drivers have traditionally been used.
Meanwhile, Pratt & Whitney, owned by United Technologies Corporation (NYSE: UTX), recently launched its so-called PurePower PW1200G engine with a high-pressure compressor
, a low-emissions combustor and a state-of-the-art stub wing, MarketWatch said Tuesday.
These benefits are achieved through improvements to the high-pressure compressor
and the high- and low-pressure turbines.
