The quad tilt rotor (QTR) has the problem of manipulation redundancy due to the helicopter and fixed-wing manipulation mechanisms. Solving the problem of manipulation redundancy and develop an effective manipulation strategy is critical for QTR during conversion flight. A novel manipulation strategy based on states of QTR is proposed in this paper to solve the problem of manipulation ... https://www.glasssstationes.shop/product-category/sidecar-bubblers/
