Yes, I think the PT6 () and the PW120 as well () have separate power turbines, where I think it is common to start the turboprop feathered. On these engines the starter doesn't turn the propeller directly, but my question is is the propeller unloaded or loaded by starting feathered. I think you...

The propeller of a turboprop engine is started with the propeller blades feathered (in-line with the flow): see video: . As the propeller speeds up and reaches idle speed while still feathered, and the incidence onto the blades is very high, does this mean that the flow over the blades is...

From a practical perspective, it may be easiest if you speak to a few of your lecturers and see if they will help you think of something - this is also good as they will be 'bought in' to the idea, and might agree to supervise it. My clear advice is to make sure the project let's you achieve...

Yes thanks, quite straightforward really. Just reading my notes from a few year's ago. thanks

Homework Statement Find the Taylor expansion y(x) satisfying: y'(x) = 1 - xy Homework Equations The Attempt at a Solution So I need expressions for y''(x), y'''(x), ...etc I can find y''(x)=-y-xy' by differentiating implicitly. By setting y'(x)=z, then dz/dx =...

Air standard Carnot cycle. I would like to simplify my question:- For the Carnot cycle:- Net work output =(ΔT)(ΔS), where ΔT = temp difference between source and sink temperatures and ΔS = entropy difference between adiabatic stages. This can be re-phrased in terms of Ps and Ts...

This is about the basic thermodynamic cycle of the gas turbine (i.e. Brayton or Joule cycle), consisting of adiabatic compression, heat addition at constant pressure, adiabatic expansion, and heat rejection at constant pressure, and the standard ways of analysing this through Pressure-Volume...
