(2022) Numerical Investigation of full helicopter with and without the ground effect, Aerospace Science and Technology, Volume 122, Issue March, Article number 1074011270-9638https://doi.org/10.1016/j.ast.2022.107401https://dspace.lib.cranfield.ac.uk/handle/1826/17598In the present work, the aerodynamic performance of the full helicopter PSP in hover flight is investigated using a simplified concept of multiple reference frame (MRF) technique in the context of high-order Monotone Upstream Centred Scheme for Conservation Laws (MUSCL) cell-centred finite volume method. The predictions were obtained for two ground distances and several collective pitch angle at tip Mach number of 0.585. The calculations were made for both out-of-ground-effect (OGE) and in-ground-effect (IGE) cases and compared with experimental data in terms of pressure distribution and integrated thrust and torque and vortex system.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/High-order methodsRotorcraftCFDIGEOGEGround effectArticle
