Crewless aerial vehicles (UAVs) are increasingly being used in civil life. UAVs come in a variety of sizes and configurations. Vertical takeoff and landing (VTOL) crewless aerial vehicle (UAV) is a UAV type that attracts interest in the UAV field due to its excellent flight performance. Fixed wing uav s combine the advantages of helicopters and fixed-wing planes, such as a small takeoff and landing footprint, as well as long-range and endurance. The tail-sitter is chosen as the research goal among various VTOL types because it adds no extra mechanism or mass to the aircraft. However, while tail-sitters have the advantage of being easy to configure, the highly coupled nonlinear system makes it difficult to construct a mature control system at this time.
The aerodynamics of a particular tail-sitter was studied using an experimental process. A real-time hardware-in-loop (HIL) simulation system was developed to develop a tail sitter’s reliable control algorithm. To meet the HILL scheme’s demands, the corresponding database for HIL was expanded to include all angles of attack. The tail-sitter UAV system’s four main components are: Airframe, navigation system, remote control, and data link are the four main components. Simulink was used to create the dynamic simulation, and the real-time application was built using the Simulink Desktop Real-Time Kernel, which supports real-time output at sampling rates up to 1 kHz. The HIL simulation method was validated by comparing the results to the corresponding later flight log data using the initial condition from the actual flight log from both in-door and out-doors tests.
Military Applications for VTOL UAVs
The CAMCOPTER S-100 is a VTOL military aircraft that provides intelligent and versatile solutions for various missions. The S-100 VTOL UAV, which can operate from remote locations and is quickly reconfigurable to meet various operational requirements, stays close to the action, whether on land or at sea.
- A Multi-Ocean Approach
With thousands of flight times, takeoffs, and landings, the S-100 has proved its maritime capabilities from 30+ different vessels across all of the world’s oceans. The military VTOL UAV has a fully automatic shipboard landing system, and it has successfully flown in winds up to 4 knots and in sea states greater than 3.
- Surveillance at a Distance
The CAMCOPTER S-100 UAS provides long-range real-time surveillance up to 200 kilometers, meeting various consumer needs. Schiebel’s ground-control user interface provides task planning and execution capabilities that have been tested in the field. It allows for fast integration with higher levels of command and control systems and payload data delivery and processing.
