real time reliability verification for uav flight control system supporting Airworthiness Certification
PLOS ONE, 2016Co-Authors: Haiyang Xu, Ping WangAbstract:In order to verify the real-time reliability of unmanned aerial vehicle (UAV) flight control system and comply with the Airworthiness Certification standard, we proposed a model-based integration framework for modeling and verification of time property. Combining with the advantages of MARTE, this framework uses class diagram to create the static model of software system, and utilizes state chart to create the dynamic model. In term of the defined transformation rules, the MARTE model could be transformed to formal integrated model, and the different part of the model could also be verified by using existing formal tools. For the real-time specifications of software system, we also proposed a generating algorithm for temporal logic formula, which could automatically extract real-time property from time-sensitive live sequence chart (TLSC). Finally, we modeled the simplified flight control system of UAV to check its real-time property. The results showed that the framework could be used to create the system model, as well as precisely analyze and verify the real-time reliability of UAV flight control system.

A survey of unmanned aircraft systems regulation: Status and future perspectives
Control and Automation, 2008 16th Mediterranean Conference on, 2008Co-Authors: Konstantinos Dalamagkidis, Kimon P. Valavanis, Les A. PieglAbstract:Any aircraft, manned or unmanned, may enter safely and legally into the US National Airspace System (NAS) provided that it has been issued an Airworthiness certificate complying with Federal Aviation Administration (FAA) requirements. Unfortunately corresponding requirements, procedures and regulations for Airworthiness Certification of unmanned aircraft are in early development stages and flight of such systems is still restricted. This paper presents a survey of the current status of unmanned aircraft system (UAS) regulations both in the US and internationally, followed by brief overview of current manned aviation Airworthiness Certification procedures and requirements. Future perspectives of UAS regulation are discussed along with a proposed UAS classification for Certification purposes.

Current Status and Future Perspectives for Unmanned Aircraft System Operations in the US
Journal of Intelligent and Robotic Systems, 2008Co-Authors: Konstantinos Dalamagkidis, Kimon P. Valavanis, Les A. PieglAbstract:An aircraft (manned aircraft) may enter safely and legally into the\nUS National Airspace System if and only if it has an Airworthiness\ncertificate complying with Federal Aviation Administration requirements.\nAlthough corresponding requirements, procedures and regulations for\nunmanned aircraft are in early development stages, they are expected\nto be similar to those set for manned aviation. This paper presents\na brief overview of current Airworthiness Certification procedures\nand requirements for manned aviation, followed by a survey of the\ncurrent status of Unmanned Aircraft System (UAS) regulations in the\nUS but also internationally. Future perspectives of UAS regulation\nare discussed along with a proposed UAS classification for Certification\npurposes, presentation of a possible Certification roadmap, as well\nas regulatory paths for ultra-light UAS.

Design Considerations of a Prototype VTOL Robotic Vehicle through Market Survey Data Collection
Journal of Intelligent and Robotic Systems, 2006Co-Authors: P Spanoudakis, Nikos C. Tsourveloudis, Kimon P. ValavanisAbstract:A detailed technical design and performance comparison of current unmanned Vertical Take-Off and Landing (VTOL) vehicles is presented as a function of vehicle maximum speed, payload, range, endurance, and propulsion configurations. Mission applications and VTOL market characteristics are used to define design specifications for a new prototype unmanned VTOL vehicle suitable for a wide range of (mostly) civilian applications. The proposed VTOL vehicle's design phase is presented, including: performance capabilities calculation, fuselage strength evaluation and weight optimization via crash/drop tests. Drop tests performed have followed standard regulations used for Airworthiness Certification of such vehicles. The proposed VTOL vehicle is currently under prototype development.

ICRA - Design specifications for an unmanned VTOL
IEEE International Conference on Robotics and Automation 2004. Proceedings. ICRA '04. 2004, 2004Co-Authors: P Spanoudakis, Nikos C. Tsourveloudis, Kimon P. ValavanisAbstract:Parametric technology based design specifications for a new unmanned Vertical Take-Off and Landing (VTOL) vehicle are presented. The design phase is followed by performance capabilities evaluation and crash/drop tests that determine VTOL strength and frame deformations. Drop tests performed have followed standard regulations used for Airworthiness Certification of such vehicles. Initial drop tests have dictated a frame re-design phase that has met set VTOL specifications. The Pro/Engineer specialized Computer Aided Design (CAD) software has been used throughout all phases and tests.

definition of an Airworthiness Certification framework for civil unmanned aircraft systems
Safety Science, 2011Co-Authors: Reece A. Clothier, Rodney a. Walker, Jennifer L. Palmer, Neale L. FultonAbstract:The development of effective safety regulations for unmanned aircraft systems (UAS) is an issue of paramount concern for industry. The development of this framework is a prerequisite for greater UAS access to civil airspace and, subsequently, the continued growth of the UAS industry. The direct use of the existing conventionally piloted aircraft (CPA) Airworthiness Certification framework for the regulation of UAS has a number of limitations. The objective of this paper is to present one possible approach for the structuring of Airworthiness regulations for civilian UAS. The proposed approach facilitates a more systematic, objective and justifiable method for managing the spectrum of risk associated with the diversity of UAS and their potential operations. A risk matrix is used to guide the development of an Airworthiness Certification matrix (ACM). The ACM provides a structured categorisation that facilitates the future tailoring of regulations proportionate to the levels of risk associated with the operation of the UAS. As a result, an objective and traceable link may be established between mandated regulations and the overarching objective for an equivalent level of safety to CPA. The ACM also facilitates the systematic consideration of a range of technical and operational mitigation strategies. For these reasons, the ACM is proposed as a suitable method for the structuring of an Airworthiness Certification framework for civil or commercially operated UAS (i.e., the UAS equivalent in function to the Part 21 regulations for civil CPA) and for the further structuring of requirements on the operation of UAS in un-segregated airspace.

Definition of airworthness categories for civil unmanned aircraft systems (UAS)
Proceedings of The 27th International Congress of the Aeronautical Sciences, 2010Co-Authors: Reece A. Clothier, Rodney a. Walker, Jennifer L. Palmer, Neale L. FultonAbstract:This paper introduces a novel strategy for the specification of Airworthiness Certification categories for civil unmanned aircraft systems (UAS). The risk-based approach acknowledges the fundamental differences between the risk paradigms of manned and unmanned aviation. The proposed Airworthiness Certification matrix provides a systematic and objective structure for regulating the Airworthiness of a diverse range of UAS types and operations. An approach for specifying UAS type categories is then discussed. An example of the approach, which includes the novel application of data-clustering algorithms, is presented to illustrate the discussion.
