Abstract
Quadrotors are one of the most favorable vertical take-off and landing aircraft (VTOL) especially for unmanned surveillance (UAV). The quadrotor offers inherent advantages over conventional helicopters. Till now rotary-wing aircrafts and quadrotors must tilt to gain movement in any direction. This tilting action can create problems especially when cameras and other sensors are used. Here, we present a solution to this problem by using four controllable vanes. Each vane is located below a rotor. The vane job is to deflect the air stream by any desired angle to move the quadrotor in that direction in the horizontal plane without causing the plane to change its horizontal attitude. Each two opposite vanes are parallel and connected to one servomotor using pushrods. This parallel deflection generates a force with a horizontal component that moves the quadrotor horizontally without tilting. The quadrotor can be maneuvered in any direction by deflecting all four vanes simultaneously with any differential angle settings. A feedback controller is designed for quadrotor attitude using the classical technique of varying the motors speed to ensure the stability and to keep the vehicle level which is very important to prove the control scheme using vanes. Various flight experiments and simulations are performed to validate the proposed concept. Actual flight experiments were conducted in a 5m x 5m x 8m space equipped with wall nets and soft ground as a safe environment. The results showed that the proposed concept may provide a promising solution to the tilting problem.
