LibrePilot is [2] a Free software unmanned aerial vehicle project for model aircraft aimed at supporting both multi-rotor craft as well as fixed-wing aircraft. Initially founded by David Ankers, Angus Peart and Vassilis Varveropoulos in late 2009, under the name OpenPilot, it was conceived as both a learning tool and to address areas the developers perceived were lacking in other small UAV ...
A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor mounted on a spinning shaft generates lift), and ornithopters (in which the wings oscillate to generate lift).
The free software approach to ArduPilot code development is similar to that of the Linux Operating system and the GNU Project, and the PX4/Pixhawk and Paparazzi Project, where low cost and availability enabled hobbyists to build autonomous small remotely piloted aircraft, such as micro air vehicles and miniature UAVs. The drone industry ...
PX4 supports the following features: Multiple vehicle types, including fixed-wing aircraft, multicopters, helicopters, rovers, boats and underwater vehicles [1]; Fully manual, partially assisted and fully autonomous flight modes [2]
The wing of a fixed-wing aircraft provides the lift necessary for flight. Wing geometry affects every aspect of an aircraft's flight. The wing area will usually be dictated by the desired stalling speed but the overall shape of the planform and other detail aspects may be influenced by wing layout factors. [30]
The reliability of the software running in airborne vehicles (civil or military) is shown by the fact that most airborne accidents occur due to manual errors. Unfortunately reliable software is not necessarily easy to use or intuitive, poor user interface design has been a contributing cause of many aerospace accidents and deaths. [citation needed]
The results of the test give the various performance characteristics of that design. Once that completes, the software makes incremental changes to the structure and shape details, recreates the model, and flies the new model through a wind tunnel. If the changes result in a better performing wing, then the software commits the changes.
