.... The research provides new data that can be used in the preliminary design of next-generation unmanned aerial vehicles (UAVs). Design/methodology/approach Forces acting on the aircraft were measured in the wind tunnel using self-developed measurement scales. The impact of wing–propeller interference...

...Fusheng Qiu; Guodong Lai; Md Helal Miah; Le Yu Purpose Wake vortices in wind tunnels disrupt flow uniformity, reduce measurement accuracy and impact aerodynamic performance, complicating data interpretation and reliability. This research addresses the challenge of wake control in a rotating test...

... the D-shaped model (g/b₂) ranged from 0.25 to 1.75 b₂. Design/methodology/approach The experiments were carried out in a low-speed open-circuit closed jet wind tunnel with test section dimensions of 1.2 × 0.9 × 1.8 m (W × H × L) capable of generating...

...Prasad G.; Bruce Ralphin Rose J. Purpose The purpose of this paper is to analyse an actual representation of ice accretions, which are important during the certification process. Design/methodology/approach Ice accretion experiments are conducted in a low-speed subsonic wind tunnel testing...

... be negligible because of the small air gravity. Thus, to achieve similitude of the propeller scaled model, the main dimensionless numbers are J, Re and Ma, ignoring the experimental relative wind turbulence, blade surface roughness, etc. Experimental models of large propellers are tested in wind tunnel...

... is supposed to be equipped with a micro jet engine. Design/methodology/approach – Experimental investigations were performed by using a low subsonic close loop wind tunnel to simulate different flight regimes such as negative stall, cruise, shallow angle climb, steep angle climb and positive stall...
