Rapid prototyping flight test environment for autonomous unmanned aerial vehicles

Test facility is essential for most engineering research activities, from modelling and identification to verification of algorithms/methods and final demonstration. It is well known that flight tests for aerospace vehicles are expensive and quite risky. To overcome this, this paper describes a rapid prototyping platform for autonomous unmanned aerial vehicles (UAV) developed at Loughborough University, where a number of unmanned aerial and ground vehicles can perform various flight and other missions under computer control. Flexibility, maintainability and low expenses are assured by a proper choice of vehicles, sensors and system architecture. Among many other technical challenges, precision navigation of the unmanned vehicles and system integrations of commercial-off-the-shelf components from different vendors with different operational environments are discussed in detail. Matlab/Simulink based software development environment provides a seamless rapid prototyping platform from concept and theoretic developments to numerical simulation and finally flight tests. Finally, two scenarios performed by this test facility are presented to illustrate its capability

Development of an autonomous control system for a small fixed pitch helicopter

The indoor test bed of the Autonomous Systems Laboratory has been used to create a control system for a small fixed pitch helicopter. This paper outlines the challenges posed by such a vehicle and the control system designed to overcome them. The control system utilized a visual tracking system to obtain state information without onboard hardware. Matlab/Simulink environment was used to facilitate rapid prototyping control development. An autopilot consisting of multi-channel PID controllers was implemented for flight tests. Failsafe strategies and gain scheduling were both investigated and implemented with the use of a graphical user interface. A number of flight tests were conducted and the results are provided. The future work of the laboratory is also covered

CONCEPTUAL DESIGN OF THE USMC FUTURE VERTICAL LIFT (FVL) LIVING LAB

The United States Marine Corps (USMC) is developing the Future Vertical Lift (FVL) system that will rely heavily on Marine-machine teaming, a complex process that requires further development. The development of a living lab (LL)—a multi-function network of simulators that will serve as the platform for testing, experimenting, and training new technologies and ideas for how the FVL will operate—will help mitigate Marine-machine collaboration and trust issues. This capstone studies the options and requirements for developing a LL through interviews, research that focuses on existing technologies and operational concepts, and Model-Based Systems Engineering tools using a systems engineering approach. The report includes a detailed needs and requirements analysis, stakeholder analysis, and functional design. The team presents a conceptual design, that includes the system architecture, comprising of system, function and physical views, system lifecycle, and the evaluation criteria for a LL. The final product is a set of use cases and concepts of operation. The USMC needs a new approach that supports rapid and relevant upgrades that optimizes the system lifecycle and keeps the Marine in mind. This team recommends the USMC consider these findings and continue researching and developing a LL.ONR Arlington, VA 22203Civilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyApproved for public release.
