“…Many early researches dealt with flight path planning ensuring landing on safe landing zones providing minimum losses and, minimized threat both to environment and to human being [4,6,7,10]. That problem often was combined with that of design of vision based automated landing of the UAV [6,11,12].…”

“…Although there are some landing systems available for manned airplanes, such as used at major airports Instrument Landing Systems (ILS), which significantly limit the number of crashes, they are not popular for unmanned aerial vehicles because of its complexity and weight. The landing processes of UAVs are therefore generally controlled manually or supported by more or less sophisticated portable external aiding systems [3].…”

Abstract. In this paper a new air-bag prototype suitable for protecting valuable objects mounted on the drone is presented. The paper provides a complimentary study involving both numerical simulations and experimental study. The experimental research results are presented for typical air-bag's textile material and were used as a base for the material model calibration process. This model was used for the numerical simulations of the proposed air-bag prototype, which were carried out in the LS-Dyna environment. Based on the outcome of the study, the proposed prototype seems to be a suitable device for preventing the unmanned vehicle equipment from unexpected accidents.

“…This capability is an inherent component for benchmarking the performance of the manned aviation industry, therefore the group identified this as a key impediment to overcome in order to allow UAVs to operate over populated areas in civilian airspace (Fitzgerald, Walker et al 2005;Fitzgerald 2007). Hence, it is believed that UAVs must therefore be provided with the ability to safely terminate the flight through a range of emergency scenarios.…”

While using unmanned systems in combat is not new, what will be new in the foreseeable future is how such systems are used and integrated in the civilian space. The potential use of Unmanned Aerial Vehicles in civil and commercial applications is becoming a fact, and is receiving considerable attention by industry and the research community. The majority of Unmanned Aerial Vehicles performing civilian tasks are restricted to flying only in segregated space, and not within the National Airspace. The areas that UAVs are restricted to flying in are typically not above populated areas, which in turn are one of the areas most useful for civilian applications. The reasoning behind the current restrictions is mainly due to the fact that current UAV technologies are not able to demonstrate an Equivalent Level of Safety to manned aircraft, particularly in the case of an engine failure which would require an emergency or forced landing. This chapter will preset and guide the reader through a number of developments that would facilitate the integration of UAVs into the National Airspace. Algorithms for UAV Sense-and-Avoid and Force Landings are recognized as two major enabling technologies that will allow the integration of UAVs in the civilian airspace. The following sections will describe some of the techniques that are currently being tested at the Australian Research Centre for Aerospace Automation (ARCAA), which places emphasis on the detection of candidate landing sites using computer vision, the planning of the descent path/trajectory for the UAV, and the decision making process behind the selection of the final landing site. IntroductionThe team at the Australian Research Centre for Aerospace Automation (ARCAA) has been researching UAV systems that aims to overcome many of the current impediments facing the widespread integration of UAVs into civillian airspace. One of these impediments that the group identified in 2003 was how to allow a UAV to perform an emergency landing.1 Dr Luis Mejias, Pillar Eng and Xi Liu are with the Queensland University of Technology 2 Dr Daniel Fitzgerald is with the ICT centre CSIRO 3 ARCAA is a joint venture between
