“…Because the UAVs do not have one wing unfolding, it seems to have been freefall immediately after failing to control the UAV properly. Smith et al of University of Nevada (2015) developed a glider which has a four-isolated fuselage mounted on a container wrapped in a flexible thin airfoil wing [41]. The UAV carried out a successful unfolding mechanism, but it was found at the distance error of 2800 meters.…”

In this study, a new method was developed to extend the flight distance of unmanned aerial vehicles such as quadcopters that operate on a limited battery capacity. The suggested method consists of a high-altitude flight initiation system, which uses a carrier rocket, and an autonomous ramp flight algorithm. First, a quadcopter, called a mission quadcopter in this research, is loaded onto the carrier rocket by a folding mechanism, and the rocket flies to a designated height. Then, the carrier rocket releases the mission quadcopter at the high altitude and achieves flight deployment after an unfolding process. Subsequently, the airdropped mission quadcopter stabilizes its pose and flights toward the selected target point. During the flight, it adopts an autonomous ramp flying trajectory. Ramp flying is performed from the sky to the ground surface instead of conventional step shape flying to minimize the flight trajectory and energy consumed while flying. Experiments were performed in Nevada, USA during an international rocket-based airdrop competition, ARLISS (A Rocket Launch for International Student Satellite). The mission quadcopter's realtime latitude, longitude, and altitude were measured to confirm the position information regarding the quadcopter's flight trajectory. The mission quadcopter successfully separated from the carrier rocket, deployed for flight at a high altitude, turned to the target point, performed autonomous ramp flying, and landed.

“…Folding mechanism and glider sizes are affected by the miniaturization of core technologies. However, the endurance of miniature drones' wings are questionable when they are exposed to maximum force [7][8][9]. The aim is to show that the wings are completely foldable even in unsuitable conditions.…”

“…Accordingly, selecting the suitable materials for the glider and finding the design parameters allow multiple gliders to be transported at the same time. For this reason, different methods such as wing-folding mechanisms have been successfully applied to reduce the volume of miniature air-vehicles in the former designs [7][8][9][10].…”

“…There are many different wing models used in literature for fixed-wing aerial vehicles, and use of Eppler and National Advisory Committee for Aeronautics (NACA) type wing structures is relatively more common [8,16]. The Eppler-793 type wing structure appears to be fit for mini-gliders and speed-critical applications, where thickness, camber, and C L /C D (efficiency) ratio are crucial.…”

“…However, our primary aim is not a only wing-folding mechanism; our designed glider, which is able to land in a controlled manner via phugoid mode, can also collect data during its descent. For different approaches in literature, although the same mechanical equipment is used, we can see that sensor data retrieval experiences mishaps during the launch process [8,9]. With this method, the amount of energy needed will be kept at a minimum, resulting in a light and compact structure.…”

This paper describes a mini unmanned glider’s design, simulation, and manufacturing with a novel wing-folding mechanism. The mini-glider is designed for CanSat competition, which has a theme of a Mars glider concept with atmosphere data acquisition. The aim is to facilitate the transportation of the glider and to land it on the destination point by following strict rules. Having a light and compact design is important since it uses power for the transmission of sensory data only. Dimensions of the glider is produced with a wingspan that is 440 mm and a length of 304 mm. The wings can be stowed in a fixed size container that has a diameter of 125 mm and a height of 310 mm. Its weight is only 144 g and it can increase up to 500 g maximum with a payload. The mechanism, which includes springs and neodymium N48 grade magnets for a wing-folding system, is capable of being ready in 98 ms for gliding after separating from its container. The mini-glider is capable of telemetering, communicating, and conducting other sensory operations autonomously during the flight.
