Ram Air Turbines (RATs) are employed to supply power for auxiliary and backup systems<br/>of an aircraft in case of a major power shortage. These turbines are commonly Horizontal<br/>Axis Wind Turbines (HAWTs). In this study, we investigate the performance of a RAT under<br/>cruise altitude operating conditions. CFD-RANS computations coupled with Blade Element<br/>Method (BEM) are conducted to examine the impact of adding Gurney flaps (GF) to the rotor<br/>blades in terms of power and drag (thrust) performance. Three different GF height<br/>configurations of 1% chord (1%c), 3%c, and 5%c are applied to the blades of a small RAT.<br/>The rotor diameter is 1.016 meters, comprising of two blades with a constant chord length of<br/>0.127 meters and a NACA 8318 airfoil, featuring twist angle along the blade span. The effects<br/>of the Gurney flaps are explored over a Reynolds number range of 200k to 500k based on<br/>the chord length, corresponding to the Reynolds number of the relative wind speed around<br/>the blade at sections of 25%, 50%, 75% and 100% of the blade. Lift coefficient (CL) and drag<br/>coefficient (CD) results were imported to Qblade to perform a BEM turbine analysis. The<br/>results demonstrate a noticeable increase in the maximum coefficient of power around tip<br/>speed ratio (TSR) of 3. Also, a comparison was made between a clean blade and a blade with<br/>GF mounted only at the root of the blade. The blade with GF representing 1% of the chord,<br/>mounted at the root of the blade yields improved CP/CT for a wider range of 3< TSR <6.6.<br/>However, a GF with height of 5%c exhibits the highest CP/CT ratio, both at low TSR (ranging<br/>from 1 to 1.8) and high TSR (from 4 to 7.6). Data validation was conducted for the NACA<br/>8318 airfoil using experimental results from Yoshida (2000). Additionally, data validation<br/>was also performed by comparing the findings with CFD data from Shen (2016) for E387<br/>airfoil performed on the low-speed wind tunnel of Queen Mary University of London. These<br/>validations aim to support and validate the results obtained within this thesis. |
