The ultra-high bypass ratio geared turbofan is a key concept to reduce the environmental impact of the next generation aircrafts. The increase in rotational speed of the low-pressure turbine (LPT) enabled by the geared architecture offers potential b

In this article, a numerical investigation of the effect of a miniaturized five-hole probe downstream of a transonic low-pressure turbine vane row is presented. First, a numerical calibration of the probe was performed in uniform flow conditions, as

One of the crucial issues affecting the structural safety of propeller vehicles is the propeller tonal excitation and related vibrations. Propeller rotation during flight generates vibrating sources depending upon its rotational angular velocity, num

The aerodynamics of a high-speed low-pressure turbine (LPT) cascade was investigated under steady and unsteady flow conditions. The tests were performed at outlet Mach (M) and Reynolds numbers (Re) of 0.90 and 70k, respectively. Unsteady wakes were s

The influence of the unsteady wakes incoming from the upstream stages is of high relevance in modern high-speed low pressure turbines operating at transonic exit Mach numbers and low-Reynolds numbers, for their potential to trigger transition and inf
