Comparison of airborne radiation detectors carried by rotary-wing unmanned aerial systems

Airborne Wind Energy Systems with Rotary Wing and Ground Generator

Airborne wind energy systems with a rotary wing and a ground generator are analyzed. These systems are very attractive from practical point of view, because of absence of tether drag, simplicity of control, launch and landing of the wing, combined with the well known benefits of AWES, including ability to reach high altitude winds and to adjust altitude dynamically to catch the strongest wind. ...

designing unmanned aerial vehicle based on neuro-fuzzy systems

در این پایان نامه، کنترل نرو-فازی در پرنده هدایت پذیر از دور (پهپاد) استفاده شده است ابتدا در روش پیشنهادی اول، کنترل کننده نرو-فازی توسط مجموعه اطلاعات یک کنترل کننده pid به صورت off-line آموزش دیده است و در روش دوم یک کنترل کننده نرو-فازی on-line مبتنی بر شناسایی سیستم توسط شبکه عصبی rbf پیشنهاد شده است. سپس کاربرد این کنترل کننده در پهپاد بررسی شده است و مقایسه ای ما بین کنترل کننده های معمو...

A Small Semi-Autonomous Rotary-Wing Unmanned Air Vehicle (UAV)

Small radio controlled (R/C) rotary-wing UAVs have many potential military and civilian applications, but can be very difficult to fly. Small and lightweight sensors and computers can be used to implement a control system to make these vehicles easier to fly. To develop a control system for a small UAV, an 8-bit microcontroller has been interfaced with MEMS (Micro-Electro-Mechanical Systems) gy...

Design and Analysis of Unmanned Aerial Vehicles Wing

wing to the material differences in the natural and engineered systems, the design of a biological-inspired aircraft possesses considerable challenges to the aircraft designer. The birds employ a structure of hollow bones, flexible joints and muscles, and feathers to morph their wings to suit the desired flight condition. While the aircrafts use the rigid joints and structures to sustain the ae...
