This paper presents an approach to wind stress estimation and wind impact modeling using data collected onboard a quadrotor drone. First, wind force and wind velocity are derived based on experimental data obta
At a very different scale the tower of a wind turbine acts as a free-field source of distortion generating tonal noise in the same way as the transmission shaft for the tail rotor. Though the corresponding frequencies enter the range of infrasound, they could be addressed similarly. Finally ...
Field experiments are carried out to prove the feasibility of the ATLC controller for an aerial manipulation.And comparing with the TLC controller for aerial arm waving experiment in [21], ATLC performs better than TLC in control accuracy. The remainder of this paper is composed of five ...
To validate and test the efficiency of the different control laws in order to stabilize the quadrotor in a wind field, accurate modeling is important, taking into account the wind speed and the external disturbances acting on the vehicle. For this reason, this chapter deals with the modeling ...
It is a cutting-edge technology in the field of modern aerospace and an important development direction of future aircraft. Morphing aircraft are classified into three types. (A) micro-, medium-, and large-scale morphing by its morphing scale; (B) internal and external flow component morphing ...
As a helpful enhancement, the researchers in [13] suggested synthesized sliding-mode control for quadcopter dynamics modeling. In [14], the developers created a control strategy to improve the energy efficiency of a quadrotor for field inspections. In paper [15], the authors proposed geometric ...
In addition, the dynamics model of the TRUAV was established based on the change of the tilt angle state, and considering the effect of rotor slip flow, we analyzed the three-dimensional flow field distribution of TRUAV in the transition mode under the aerodynamic disturbance of the fuselage ...

designed a proper set of control inputs for a UAV system, considering the wind disturbance action [30]. Hai-long et al. devised a proportional-integral nonlinear controller for the attitude control and the trajectory tracking of drone systems [31]. Amir and Abbass proposed a simplified ...
One approach to mitigate radar threats during flight is through strategic flight path planning in relation to radar locations. To minimize the probability of detection by radars dispersed throughout a battlefield while optimizing fuel efficiency, aircraft employ various algorithms to determine the optimal...
