An annular array of turning vanesis provided in a ductof a gas turbine engine. The annular array of turning vanescomprises aerodynamic vanesand strut-vanes. The strut-vaneshave greater chord length and extend further axially downstream than the aerodynamic vanes. The leading edge of the strut-vanesis upstream of the trailing edge of the aerodynamic vanes. The strut-vanes provide flow turning. The arrangement allows the ductto be axially short.

The strut-vaneshave greater chord length and extend further axially downstream than the aerodynamic vanes. The leading edge of the strut-vanesis upstream of the trailing edge of the aerodynamic vanes. The strut-vanes provide flow turning. The space to chord ratio of the aerodynamic vanes that are closest to the suction surface of a strut-vane is higher than the space to chord ratio of aerodynamic vanes that are closest to a pressure surface of the strut-vane. The arrangement allows the ductto be axially short.
