These two days, the Yidi drone released a new product in the Bird's Nest Brush Xiaobian's friends circle, the extent of the drone is really surpassing the imagination of the earth. However, Xiaobian feels that I can't just want to see the lively masses. I know that I have to know what it happened, so Xiaobian will come to take everyone a long-term hero - open source project.
Curious babies will definitely ask, open source projects have a relationship with drones? It is also a lot of open source projects related to drones to promote rapid development in this area. Like NASA, ECO, Google, Linux, MIT, etc. provide a large number of open source projects to support teams and individuals to conduct aircraft design, flight control R & D, performance analysis, project management, etc. These projects have formed a lot of mature open source design software and open source flying control hardware and hardware, such as a fence that has been swaying is ... Well, no matter how the truth, a certain fact is that these open source projects have greatly promoted now. The explosive development of human-machine can be said to be the behind-the-scenes of the drone progress.
So, today Xiaobian will take you to understand the famous open source projects of the drone world, and thanks to ASSCI scientists' selfless sharing.
I. Open source software - UAV design analysis
In the field of drone, there are also many open source projects available, which is convenient for startup. Here is some open source software that can be applied during the drone design process, including AVL, APAME, and SU2, all of which meet the open source software for GNUGPL.
Fast solution selection
In the initial stage of the aircraft design, the designers have multiple options, how to quickly assess the overall performance differences in different programs are critical to the option to meet the design needs.
AVL is a pneumatic analyst program developed by MIT Professor Markdrela, with a flattening vortic method, which can give aerodynamic performance and rudder field efficiency in a few seconds. The designer will optimize the design of pneumatic layout, airfoil selection and rudder surface according to the analysis results.
APAME is a three-dimensional partial law solver developed by Daniel, which can be evaluated in a few minutes. The surface method can give a more accurate resistance assessment relative to the vortex method, which is convenient for designers to design the maximum lift resistance ratio, cruise attack.
2. Detailed analysis
SU2 is a three-dimensional CFD solver developed by the Stanford University Aerospace School, which can make a detailed pneumatic assessment of the aircraft within a few hours. The CFD method can provide accurate power, torque results, can help designers perform more accurate optimization of local details such as wing fusion, load layout.
Second, open source hardware - the core of drone
Several famous open source software projects mentioned just, because there are many contents involving fluid mechanics, but the multi-rotoring aircraft rarely consider this part, so people know that people may not be much. But some of the items shared below are families in the drone circle, but also benefit from these projects, more drone enthusiasts, and commercial teams have the ability to develop drones.
1. Open source drone flight control APM, PX4, Pixhawk
APM (Ardupilotmega) is a flying control product launched by DIY drone community in 2007, which is the most mature open source flight control project. Diydrones was founded in 2007 in the founder of 3dr.

Pixhawk Flight Control is a son of PX4 flying control, but it is better than blue and better. The Joint APM Team and the PX4 group were introduced in 2014, with PX4 and APMs, two fasteners and corresponding ground station software. Pixhawk's performance currently has sufficient surplus, which can have a broader extension space.
2. Open source drone project DRONECODE
Dronecode is an open source project that is jointly launched by 12 technical companies in 2014 by LinuxFoundation. The aim is to build a shared open source platform for drones, providing the developers of the drone providing the resources, tools, and technical support required. It hopes to bring all independent developments and development projects to coordinate combat, brainstorm, and speed up the development process in drones and robots.
Developers don't have to develop everything from head from head, because many people have done a lot of work in drone systems. Among them, many drone projects are written in Linux code, but they are all in the case of zeroading distribution. The launch of this new project is equivalent to establishing a chat group, uploading resources developed by various fields to group files. Not only provides public resources for drone systems and tool developers, but also a role in communicating and management.
The project will be mainly regulated by LinuxFoundation, 3DROBOTICSCEOCHRISANDERSON, and Boxceoaaronlevy will also provide assistance. The project's support enterprises have increased from the initial 12 to nearly 50. 3DR has been a platinum member from now on, and its participation has played an important role in the development of drone flight control.
According to LinuxFoundation Executive Director Jimzemlin, 2014 has more than 1200 developers working for the DroneCode project and have 170,000 users to download open source code using DroneCode.
