What are booster stages in aviation Gas Turbine

AI Thread Summary
Booster stages in aviation gas turbines refer to low-pressure compressor stages that increase air pressure before it enters high-pressure compressor stages. These stages are crucial for enhancing overall engine efficiency, particularly in turbofan designs. The discussion highlights the relationship between fan and booster stages, noting that both can be driven by a single low-pressure turbine. However, due to the speed differences between the low-pressure compressor and the fan, a gearbox may be necessary to synchronize their rotational speeds. Understanding the role of booster stages is essential for effective gas turbine design.

Guys, I was reading about Turbofan and somewhere while browsing Defence Turbofan engines I came across Booster stages, but I didn't find any description or what are booster stages in Gas Turbine (Axial Compressor)
 
Physics news on Phys.org
I design gas turbines, & I've never heard that term for turbofans. Only has meaning to me with regard to rockets.
 
The booster is a low pressure compressor stage. Prior to ramping up the pressures with the HP compressor stages, (or in cases where the bypass is used to boost pressure for addition downstream) the air will be gradually brought up in pressure by LP stages, sometimes called booster stages.
 
Thank You Travis King... tell me one thing more if fan and booster stages are driven by one LP turbine then is it necessary that we have gearbox in between booster stage and fan. Because as far as I know there Speed (rotational) difference between LP compressor and fan
 

Thread 'Radiation Hard Electronic Design for LVO Long Mission'

Venus does not have a magnetosphere, so the Galactic Cosmic Rays (GCRs) environment shall be much worse than in a LEO environment. Looking to the std radiation models for Venus, the standard radiation-hard space level electronic component with tested immunity LET = 85 MeV-cm2/mg seems not enough, so, for example, a 1cm2 Si die will suffer considerable flux above this level during a long mission (10 years for example). So, the question is, usually we are not paying attention to latch-up...

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/

Thread 'SpaceX Starship development: 7th flight January 10'

Watch the progress live This is a fully stacked Starship (top) and Super Heavy (bottom). A couple of too-small-to-see cars near the bottom for scale, I also added a Saturn V and the Statue of Liberty for comparison. 120 meters tall, about 5000 tonnes when fully fueled. Twice the mass and over twice the thrust of Saturn V. The largest rocket ever built by mass, thrust, height, and payload capacity. N1 had the largest diameter.[/size] But its size is not the revolutionary part. It is designed...
