“…The constructed test module mounts on the top of a car and utilizes the vehicle's forward velocity to simulate a flight environment. The module developed for this task, called the propulsive unloading performance indicator (PUPI), is designed to quantify the performance of propeller-motor combinations intended to drive the Genii unmanned aerial vehicle (UAV; Chaney et al 2013). This requires measurements of thrust, torque, rotational frequency, voltage, and current draw.…”

“…Wind tunnel tests of propellers suitable for small UAVs are well documented in the literature. Brandt and Selig (2011) and Merchant (2004) document information on the thrust coefficient, power coefficient, and efficiency of low-Reynolds-number propellers, but for operation below the intended power level and with smaller propellers than desired for application with the Genii UAV (Chaney et al 2013). Similar wind tunnel tests were performed by Ol et al (2008) and were compared to a hybrid propeller performance algorithm.…”

In an effort to assess motor and propeller performance for small unmanned aerial vehicles (UAVs), a car-top test module has been developed. This device allows for characterization of propeller and motor combinations in mean flow without the investment that is inherent with wind tunnel testing. Additionally, propulsion systems can be tested for reliability in real-world environments without risk to an airframe. Measurements of the propeller efficiency, thrust coefficient, power coefficient, and temperature of the motor and the electronic speed controller as initial parameters of interest are reported. Thrust at different advance ratios is compared to data from wind tunnel testing in order to gauge the accuracy of this technique. The module performed well in its intended role, and it is recommended that similar devices be used for time-critical or low-cost applications.

“…Rotation of such a structure cannot be implemented directly from the power drive because the rotation axis has a hole, where the wires are placed [9]. Therefore, it was necessary to design a reduction unit, which would transmit the drive from the servo drive with the help of gears [10]. Taking into account a limited rotation ability of the servo drive within the range of 120⁰, at the first stage it was decided to make a multiplier with a transmitting angle of 2:1 that would increase the angle of camera rotation up to 240⁰ [11].…”

-Unmanned aerial vehicles (UAVs) are equipped with video surveillance devices (video cameras, photo cameras, infrared cameras, thermal imagers, etc.). Small aerial vehicles are most often equipped with stationary video cameras. However, for large-scale filming it is necessary to provide rotation of the camera in one or several planes. This article covers different opportunities to film objects or area irrespective of the AV flight path.

“…Project 1 -the hydrogen-powered UAV, as part of two Ph.D. student dissertations, was documented extensively in the literature [7], [8], [9]. It was supervised overall by two Ph.D. students, with four additional committed undergraduates, as well as 15 other students working on the project intermittently.…”
