The present work is aimed at analyzing and modeling the aerodynamic interactions of two
small-scale tilted propellers operating at low Reynolds numbers near the ground. Two …

In this work, we conduct a numerical investigation of a hexacopter for urban air mobility,
emphasizing the interactional effect between different components of the vehicle on the …

Interactional aerodynamics of a quadcopter in hover is numerically investigated in this study.
The main objective is to understand major flow structures associated with unsteady airloads …

In recent years, with the development of intelligent technology, rotorcrafts have been widely
used in unmanned collaborative missions due to their excellent maneuverability and vertical …

Rotor plays a vital role in the dynamical system of an unmanned aerial vehicle (UAV).
Prominent aerodynamic and acoustic performance are a long-term pursuit for the rotor …

Multirotors flying in close proximity induce aerodynamic wake effects on each other through
propeller downwash. Conventional methods have fallen short of providing adequate 3D …

The marsupial unmanned aircraft system (UAS) consists of a large parent unmanned aerial
vehicle (UAV) and multiple small children UAVs that can be launched and recovered in the …

The paper presents a two-layer, disturbance-resistant, and fault-tolerant affine formation
maneuver control scheme that accomplishes the surrounding of a dynamic target with …

During continuous spraying operations, the liquid in the pesticide tank gradually decreases,
and the flight speed changes as the route is altered. To maintain stable flight, the rotor speed …

During closed-range rotorcraft missions, strong aerodynamic disturbances occur between
multiple aircraft, thus affecting the stability and safety of cooperative flight processes …
