Flying Wing for Search and Rescue
I've been working on designing a flying wing UAV since 2 months now. Human search and rescue using an autonomous drone is the prime objective of this project.
One of the major aim of our project is to show how a visual human detection system that uses images from a normal camera can be implemented in software. The system would fit into the larger context of disaster management and more specifically how it can benefit search and rescue operations.
So the first prototype was made but it couldn't fly all that well. The tips stalled while rolling(probably because of no twist and less sweep) and led to a disastrous crash. As soon as our first prototype failed we got down to designing the second version.
I need some advice with the design of the second air-frame.
So I'm pretty satisfied with the numbers Xflr is churning up for the second prototype. But I'm unhappy with the kind of performance I'm getting.
Also I'm a bit skeptical about the amount of twist I've to give to prevent my wing tips from stalling. I'm using the Pankin twist formula and it gives approximately -9 degrees of twist. I'm not sure if this is usual for flying wings or not. I was told anything between 4-15 is normal.
So my doubts about the design are :
1) Is the twist alright or should i reduce it a bit ?
2) What can I do to improve my max Cl/Cd ?
3) Any other design faults you guys see in the design ?
Also some updates on the Image processing part.
HOG detector was successfully tested on a sample camera feed.
Thank you for your time and consideration.
