Volvo Optimizes Rear Turbine Frame to Reduce Weight, Cost of New Engine
Volvo Aero has delivered the first optimized fabricated turbine
rear frame for the new ANTLE (Affordable Near-Term Low Emission)
engine, being developed by Rolls-Royce. The new assembly is designed
to cut production costs by 30% and reduce weight by 10% for the
new rear frame. An important tool in the optimization process
is the extensive use of weld process modeling. Weld sequence and
parameters were computer-optimized to minimize distortion and
residual stresses. Volvo is a partner in the European engine demonstrator
program EEFAE-Efficient and Environmentally Friendly Aero Engine-costing
over 100 million euros.
