Design of a 3 Stage Axial LP Turbine for Aeroengine Applications

Design Target
To develop a high performance 3 stage axial LP turbine in a 6 weeks period time frame to help in a competitive bidding process with other competing aeroengine
manufacturers.

Deliverables
High performance LP turbine developed within 5 weeks.

Impact
The high performance of the turbine enabled the client to beat other major aeroengine manufacturers and win the competitive bid. The turbine has already been manufactured and flown in an aeroengine.
