چکیده
Unmanned aerial vehicles (UAVs) are gaining in popularity and sophistication today’s modern world. UAVs now available a wide range of configurations. A UAV’s many applications include photography videography target tracking. The upward-pointing propellers some fixed-wing make it possible for them to take off land vertically. Surveillance intruder inspections two areas where the blended wing body (BWB) configuration shines. This is because its weight spread uniformly throughout body, radar signal weaker than that alternative configurations, there relatively small amount interference with movement. With common design factors mind, like vertical takeoff landing, aerodynamic drag, fundamental stability, optimal BWB plan form surveillance designed. CATIA used finish conceptual BWB-based UAV. fluid-structure interaction (FSI) study carried out after model has been examined ANSYS Fluent. responsiveness improved through simulation MATLAB environment proportional-integral-derivative-type altitude controller was developed. results demonstrate providing UAV an instruction enhances performance. Given flexibility suggested design, we have decided limit maximum forward speed 75 m/s rate ascension 50 m/s. Rapid one seen here quite helpful dangerous situations.

Aerodynamic Design Optimization Studies of a Blended-Wing-Body Aircraft
Abstract The blended-wing body is an aircraft configuration that has the potential to be more efficient than conventional large transport aircraft configurations with the same capability. However, the design of the blended-wing is challenging due to the tight coupling between aerodynamic performance, trim, and stability. Other design challenges include the nature and number of the design variab...

A terrain-following control approach for a VTOL Unmanned Aerial Vehicle using average optical flow
This paper presents a nonlinear controller for terrain following of a vertical take-off and landing vehicle (VTOL). The VTOL vehicle is assumed to be a rigid body, equipped with a minimum sensor suite (camera, IMU and barometric altimeter) maneuvering over a textured rough terrain made of a concatenation of planar surfaces. Assuming that the forward velocity is separately regulated to a desired...

متن کاملCirculation-controlled high-lift wing for small unmanned aerial vehicle
Small unmanned aerial vehicles (SUAVs) have recently attracted considerable research and development interest owing to their small size, portability, and limited operational risk. In SUAVs, the Reynolds number Re is typically very low because they are small and fly at low speeds. The Reynolds number strongly influences the airfoil performance, and at Re = 10, the lift-drag (L/D) ratio decreases...
