“…Regarding the design procedure, Crouse et al [10] presented many useful aspects of a multi-domain vehicle. While some steps of the design procedure are also addressed in the literature [11], there is yet to be specified a complete, step-by-step conceptual design methodology that also integrates aspects of the multi-domain mission, such as the ingress and egress maneuvers.…”

In this work, the conceptual design methodology of a hybrid Unmanned Aerial Vehicle (UAV) – Unmanned Underwater Vehicle (UUV) platform is presented. As the mission complexity and the need for interoperability between different platforms grows more demanding by the day, hybrid platforms are becoming an essential solution. Hybrid UAV-UUVs can operate seamlessly and repeatedly in both the aerial and underwater environments, something that numerous animal species already execute in an optimized way. The design methodology starts with the review of the few available prototypes, creating initial design trends and continues with analytical calculations. These calculations are based on aircraft design textbooks and are modified to take into account the special characteristics of a hybrid platform, such as the means of transition between the water and the air. A Blended Wing Body (BWB) layout configuration is selected for the numerous aerodynamic advantages that it offers. The analytical calculations are then validated with the use of high fidelity CFD calculations. The results from the conceptual design phase indicate that the proposed methodology for hybrid UAV-UUV configurations provides a good design accuracy. Finally, the outcome of this methodology, which is a hybrid UAV-UUV platform is potentially the answer to the operational gap for missions that include both underwater and aerial environments.

CFD Based Investigation on the Hydroplaning Mechanism of a Cormorant’s Webbed Foot Propulsion

et al. 2020

Aquatic unmanned aerial vehicles (AquaUAV) have aroused much attention from researchers, though no fully-featured aerial-aquatic UAV exists so far. The assistance of webbed foot hydroplaning can accomplish rapid takeoff of a cormorant. A significant impact force and moment can be generated due to the webbed foot propulsion in the water-to-air transition. However, the change law of force and moment experienced by the cormorant during takeoff has not been captured. Based on previous achievements in the biological investigation, we developed a biomimetic prototype with curve fitting model and parameter optimization to attain specific movements to imitate cormorant's hydroplaning strategy. The bionic webbed foot considers the elastic mechanics, and the forepart is regarded as flexible material for fluid-structure interaction (FSI). Dynamic process of rapid takeoff in the aspects of flow characteristics and mechanical properties can be estimated by computational fluid dynamics (CFD) in our proposed FSI model, which establishes a foundation for further applications in the design of the assisted propulsion system of aerialaquatic UAV. INDEX TERMS Biomimetics, computational biophysics, fluid dynamics, coupled mode analysis, military aircraft.

“…To solve the problem above, the vehicle is designed as shown in Figure 1. Refer to some submersible unmanned aerial vehicle [14][15] and special-shaped underwater vehicle [16][17][18][19][20] , ULSI-AUV adopts underactuated structure, and four vertical thrusters of AUV are symmetrically installed on xy-plane, and each thruster has the same thrust dynamic characteristics in both forward and backward directions. This kind of thrust mechanism can be used to decouple the control force, therefore keep the depth and anti-rolling conveniently.…”

Abstract In this paper, we consider station keeping control law for ultra-silent autonomous underwater vehicle(ULSI-AUV) based on the sliding mode controller. The mechanical system of ULSI-AUV prototype is designed and manufactured, and the electrical system is selected and installed. The kinematic and dynamics model is established. The goal of station keeping control is to make the ULSI-AUV prototype fixed-depth and anti-rolling to carry out underwater operations. Numerical results show the effectiveness of this method. In addition, real-time experimental results also prove the effectiveness of the proposed algorithm.
