Powered parafoil systems are nonlinear systems that are easily affected by the surrounding
complex environment. In this study, an eight-degree-of-freedom (DOF) model of a powered …

Winds are the major contributors to the tracking error in the control process of the powered
parafoil, making it difficult to achieve better control performance. To address this problem, an …

Trajectory optimization is essential for all unmanned aerial vehicles, especially the parafoil
delivery system, as the optimized trajectory must be practical and realizable. However, with …

Parafoil airdrop is an important way to deliver goods and materials to area where road
vehicles are not easy to reach. However, it is difficult to deliver large quantities of goods and …

A novel framework is established for accurate modeling of Powered Parafoil Unmanned
Aerial Vehicle (PPUAV). The model is developed in the following three steps: obtaining a …

The ram-air parafoil, which can be controlled to achieve stable and precise landing, plays an
important role in the field of precision airdrop. The overall goal of the paper is to discuss the …

To overcome the limitations of current parafoil precision landing capabilities, an efficient real-
time convex optimized guidance and control strategy is presented. The parafoil guidance …

This study focuses on the identification of aerodynamic coefficients through airdrop data
based on a known six-degree-of-freedom (6-DOF) model. Since the precise modelling of the …

Abstract For a Joined-Wing configuration UAV, the front and rear wing are joined at the
wingtip, but they are far away at the roots, and their areas are comparable. These special …

Traditional trajectory optimization methods for the parafoil system set fixed-point landing as
the objective. However, in recent payload fairing recovery missions, the recovery system …
