“…This indicates that the viscous drag needs to be taken into account during both analysis and design of the SRVs. A more recent computational-fluiddynamics (CFD) analysis using a Reynolds-averaged Navier-Stokes (RANS) solver showed increased thrust levels due to application of SRVs [7]. However, in the same study, it was found that the total system efficiency was reduced, stressing the importance of proper SRV design and integration.…”

Swirl-recovery vanes (SRVs) enhance propulsive efficiency by converting the rotational kinetic energy in a propeller slipstream into additional thrust. This paper discusses the aerodynamic and aeroacoustic impact of the installation of a set of SRVs downstream of a single-rotating propeller. Experiments were carried out in a large low-speed wind tunnel, whereas simulations were performed by solving the Reynolds-averaged Navier-Stokes equations. Favorable comparisons between the experimental and numerical slipstream data validated the simulations, which predicted a maximum propulsive-efficiency increase of 0.7% with the current design of the SRVs. This can be improved further by optimizing the pitch distribution of the SRVs. The upstream effect of the SRVs on the time-averaged propeller performance was negligible. Yet, small but systematic unsteady propeller loads were measured with a peak-to-peak amplitude of at most 2% of the time-averaged loading, occurring at a frequency corresponding to the five SRV passages during one revolution. The downstream interaction was one order of magnitude stronger, with unsteady loading on the SRVs with a peak-to-peak amplitude of about 20% of the time-averaged load. The interaction mechanisms caused an increase of the tonal noise levels of 3-7 dB, with the noise penalty decreasing with increasing propeller thrust setting.

“…Recently, the SRV concept was reintroduced by research groups at Delft University of Technology and Northwestern Polytechnical University. In the numerical SRV design process performed by Wang et al [15] and Stokkermans et al [16], the vane shape was parameterized and optimized. In both studies, a gradient-based optimization routine was coupled with an SRV analysis tool.…”

“…In [2,3], studies on the use of finite plates are presented. In [4], it was proposed to install a number of stationary blades located downstream of the propeller for the untwisting of the tip vortex. Such measures can reduce secondary losses and increase propeller efficiency by an average of 3-5 %, but they do not solve the problem of propeller dimensions and increase the aerodynamic loading on the blade.…”

The propeller, as a thruster, has been known for a very long time and has been the only possible mover in aviation for many years. The increase in flight speed, the emergence of jet, and then turbofan gas turbine engines significantly reduced the use of propellers. However, it should be noted that today the propeller has no competitors in terms of profitability at moderate flight speeds (M≤0.6, and in the case of coaxial counter-rotating fans, M≤0.8). Also, propellers 22. Lovska, A. (2018). Simulation of Loads on the Carrying Structure of an Articulated Flat Car in Combined Transportation. Interna-
