![]() ![]() Nevertheless, it is designed primarily for demonstration purposes. For example, the Zapata Aquadrone is equipped with an electric pump and four electric motors rotating four thrust nozzles for self-manipulation. Newly developed products can operate autonomously, thanks to the use of sensors, actuators, and automatic controllers. Especially, most of the water-powered systems are manual or semiautomated such that only trained and skilled people are able to operate them. Secondly, their flight distance is limited by the length of the water-conveying hose. Firstly, the systems require a substantial amount of water for propulsion. However, their inevitable drawbacks make them currently only applicable to hydroflight sports or show performances. With this maneuverability, water-powered systems have the potential for many aerial operations. ![]() Thereby, the rider can perform complex movements, such as turning, flipping, or spinning. The rider controls the system either by leaning their body (as is the case for flyboards and hoverboards ) or by rotating the direction of the water nozzle (as is the case for jet packs and jet bikes ) to ride. In general, their operation basics is that the water jetted from the nozzles underneath the head assembly generates thrusts and lifts off. Structurally, each of these systems features three main components: a jet ski that pumps water, a water-conveying hose, and a head assembly that carries a rider. Especially in hydroflight sports, it is very likely that readers have seen spectacular performances performed by these systems either online or in person. These days, water-powered aerial systems are becoming popular. Computational studies in comparison with previous control methods validated the superiority and feasibility of the proposed control system. The design takes distinct characteristics of the system, such as coupling, under actuation, and effects of the hose conveying the water, into consideration so that the system is stabilized and uniform ultimate boundedness is achieved. Then, the nonlinear controller is designed to ensure the desired system motion and stability. The paper first formulates the system dynamics by coupled partial ordinary differential equations. Unlike existing water-powered systems, an assembly of flow-regulating actuators is proposed to fully operate the system in three-dimensional space. In this study, we design an effective controller for a novel water-powered aerial system that aims for autonomous firefighting missions, especially at or in bodies water. However, they require the direct involvement of trained operators to control, and their applications are very limited. Flying water-jet propulsion devices, such as jet boards, jet packs, and jet bikes, can execute complex flight maneuvers. ![]()
