Experimental and numerical analysis on geometrical optimization of miniquad-rotor to improve the time duration

e article discusses lift force generated by mini quad-rotors. CFD (Computational Fluid Dynamics) simulations were made on the base of a 3D scanned propeller model. Influence of some geometrical parameters of propeller (like velocity or pitch) and quadcopter (like gap) on lifting force was considered. Different propeller pitches were used and pitch influence on propeller lift force was analyzed. ... ادامه مطلب

Numerical simulation of a quadrotor blade based on structure effect at staticthrust conditions

Drone propellers are rotating wings producing lift in the direction of the axis of rotation. Propeller blade design is critical to generate enough thrust to carry the takeoff weight and reduce aerodynamics noise level. In this project, numerical analysis is conducted for the aerodynamics performance of two propeller designs at the static thrust condition. ... ادامه مطلب

معرفی سامانه پهپاد فتوگرامتری

پیدایش الگوریتم های پیشرفته پردازش تصویر موجب گردیده تا بتوان از تصاویر غیر متریک اطلالاعات هندسی با ارزشی را استخراج نمود که در مقایسه با روش های رایچ کلاسیک فتوگرامتری یک جهش روبه جلو محسوب می شود. ... ادامه مطلب
