Propeller installation effect and surrogate based optimization of a tail-sitter drone
The propeller of tail-sitter UAV plays the role both in providing thrust and obtaining control forces. The beneficial installation position of propellers considering thrust, L/D and roll moment control force was studied in this paper. RANS CFD method with MRF treatment for propeller rotation regimes was applied. The slipstream of baseline installation makes the aberration of the wing pressure and span load distribution, which make lift reduced by 6.9% and drag increased by 14.3%. 5 × 5 matrix of installation location was studied by CFD. The stream wise location has significant effect on the cruise L/D, on the other hand the vertical wise location make significant effect on the cruise thrust and hovering control force. Three objectives optimization based on surrogate model was conducted. The cruise L/D and hovering control force were improved by 6.93% and 6.1% respectively with a few cruise thrust loss.
