“…The pitch-strut system comprised a strut, a threaded rod (NC4-32), and a stepper motor drive (KTC-5034-349-K). To calibrate the pitch-strut system, the relationship between the number of steps taken by the motor and the angle of attack of the model was verified [27]. The step motor offers a static torque of 1.86 N • m, with a step angle of 1.8 • and a precision of 5%, as well as a continuous power of 25 W. The model was positioned vertically, thereby ensuring that, while the angle of attack changed, a reference point at the root of the fore wing remained centered within the tunnel.…”

“…These adjustments were carefully determined to promote the development of fully turbulent boundary layers during the experimental campaign, thereby aligning the model's behavior with that of the full-scale aircraft.

The aerodynamic design of a new aircraft concept was investigated through subsonic wind-tunnel testing using 1:28-scale powered models. The aircraft configuration integrates a box-wing layout with engines located at the rear part of the fuselage. Measurements involved a back-to-back comparison between two aircraft models: a podded version whose engines were assembled on pylons and a boundary-layer ingestion (BLI) version that provided several system-level benefits. The flowfield was investigated through the power balance method and a variety of pressure flowfield and inlet flow distortion metrics. The results proved that the BLI configuration enhances the propulsive efficiency by reducing both the electrical power coefficient and the kinetic energy waste due to lower jet velocities. Furthermore, there was a reduction of the total pressure recovery due to pressure gradients inside the duct, thereby causing high distortion. Overall, this research highlights the importance of wind-tunnel testing to bring any aerodynamic technology to a sufficient level of maturity and to enable future new aircraft concepts.
