The principle of operation and chosen examples of construction of SI engines designed to be powered with aviation fuel (Heavy Fuel Engines – HFE) have been presented in the article. Contemporary solutions of the HFE combustion system constitute the further development of a patent of an Australian company Orbital working in the field of two-stroke SI engines. Engines of this type, characterized by low weight and low value of specific fuel consumption, are used among others for the propulsion of drones (Unmanned Aerial Vehicles – UAV), where range and endurance are essential parameters. That is also a practical realization of the military logistical concept of using a "single fuel in the battlefield".

Abstract The text deals with the development and methods of use of Drones or Unmanned Aerial Vehicles in contemporary conflicts or special operations. The contribution tries to present the main advantages of these vehicles as being the main reasons for their current use in armed forces of state as well as non-state actors and their dynamic proliferation in global space in past years. We can observe a new trend in the armed conflict in the last two decades - use of advanced systems of unmanned vehicles in such a range that many military and academic experts talk about a new wave of revolutionary changes in the military affairs. This wave, or we could even talk about militarytechnological breakthrough should lead to imminent use of these systems in contemporary as well as future conflicts which would result in the partial or complex robotization of the battlefield. Specific attention is dedicated to controversies tied to the use of Drones/Unmanned Aerial Vehicles in socalled Drone Warfare and current discussion in the context of cultural or societal dimension of their use and perspectives for further development.

Abstract Over the past decade, unmanned aerial vehicles (UAVs) have received increasing attention and are being used in the areas of harvesting, videotaping, and the military industry. In this article, the consideration is focused on areas where video recording is required for ground inspections. This paper describes modern communication technologies and systems that enable interaction and data exchange between UAVs and a ground control station (GCS). This article focuses on different architectures of communication systems, establishing the characteristics of each to identify the preferred architecture that does not require a significant consumption of resources and whose data transmission is reliable. A coherent architecture that includes multiple UAVs, wireless sensor networks, cellular networks, GCSs, and satellite network to duplicate communications for enhanced system security has been offered. Some reliability problems have been discussed, the solution of which was suggested to be a backup connection via satellite, i.e., a second connection. This study focused not only on the communication channels but also on the data exchanged between system components, indicating the purpose of their application. Some of the communication problems and shortcomings of various systems, as well as further focus areas and improvement recommendations were discussed.

Abstract The technology of unmanned aerial vehicles (UAV) has constantly developed in the last decade, becoming a key feature of the military programs and operations in Europe and the US, and the industry market has considerably grown. The vast majority of this growth is at the US level, whose military budget is bigger than of any other state in the world. On the other hand, with respect to the civil market, the sale of these kinds of aircrafts is in its initial stages, even though there are lots of fields in which it can be applied. In general, the states have begun to take legislative measures so that the unmanned flight of such an aircraft in areas open to civil aircrafts is controlled, so that any danger to the civil aircrafts should be avoided. The countries of the European Union that have not legislated this field are subject to Regulation 216/2008/EC regarding common norms in the civil aviation field and the Chicago Convention. Furthermore, all EU states are NATO members and thus apply in principle the norms established by the North-Atlantic Organization.

Password-based authenticated key exchange is a popular method for secure authentication and key exchange. With the wide application of unmanned aerial vehicles, position information has also become an important factor in authentication. In this paper, we present a new key exchange protocol, which firstly realizes dual authentication for both password and position, and we propose two applicable scenarios for the PPAKE mechanism: one is unmanned aerial vehicle authentication, and the other one is authentication in the military base. By adding position authentication, the reliability of authentication has improved, and the difficulty of adversarial attacks also increases. Any arbitrary adversary who can listen, tamper, and send messages can only perform an online attack for password guessing at a specified position. Finally, we provide security proofs under the defined model.

Blind Spots

Contemporary warfare has been significantly transformed by the promotion and implementation of unmanned aerial vehicles (or drones) into global military operations. Networked remote sensory vision and the drones’ capability to carry deadly missiles entail and facilitate increasingly individualised, racialised, and necropolitical military practices conceptualised as ‘surgical strikes’ or ‘targeted killings’, all in the name of ‘counterinsurgency’. In the absence of publicly accessible documentations of ‘drone vision’, images of drones themselves constitute what is arguably one of the most contested iconographies of the present. The ethical and legal problems engendered by the virtualisation of violence and the panoptical fantasies of persistent vision and continuous threat interfere with the commercial interests and the publicised ideas of ‘clean’ warfare of the military-industrial-media complex. Drones have become a fetishised icon of warfare running out of human measure and control and are henceforth challenged by activist strategies highlighting the blind spots and victims of their deployment.

Physical Principles

The protection of various objects against the impact of unmanned aerial vehicles (UAVs), which carry a potential threat in the military, economic and everyday areas of human activity, is one of the urgent tasks of our time. Currently, there are a large number of publications devoted to the description of methods and systems based on different physical principles designed to detect and observe UAVs against the background of existing interference. They consider the reception channels, methods of processing the received information signals and their subsequent intelligent analysis. It is shown, that the known methods of energy detection of UAV signals are insufficiently effective, since the operation is performed, as a rule, against a background of noise that has certain structural similarities with the UAV signal. Considerable attention is paid to the methods for interpreting the obtained data using trained neural networks. Since the number of publications in this area is constantly increasing, the task of analyzing, generalizing and systematizing the data available in the literature is relevant in accordance with this. The article is an overview and it is devoted to the generalization and systematization of known methods of receiving and processing radar, acoustic, optical and infrared signals for detection-recognition, measurement of coordinates and parameters of UAV movement.

Considering that there are promising ways to combat unmanned licensed vehicles for other field warehouses stored in combat situations. The experience of conducting the Joint Forces Operation (ATO) in eastern Ukraine, as well as the negative cases that have recently occurred in the field artillery depots and stationary arsenals (bases) of the Armed Forces of Ukraine, shows that the system of storage of missiles and ammunition in the field artillery depots of The Ukrainian forces are outdated and need major upgrading and modernization. Based on the analysis of the provision of troops with missiles and ammunition, for the period from 2015 to 2016 for the destruction of ammunition storage facilities, both stationary (arsenals, ammunition storage bases of the Armed Forces of Ukraine) and field depots of the units of Incorporated Forces effectively uses unmanned aerial vehicles (UAVs). The most illustrative examples of UAVs are: fire and explosion at the field warehouse of ammunition storage at the combined RAW field warehouses (Svatovo, Lugansk region) on October 29, 2015; attempt to carry out a diversion at the arsenal of storage of missiles and ammunition (Balakley) with the help of UAV December 26, 2015 (dropping packages with incendiary mixture that could not be extinguished by ordinary fire extinguishing means); fire on the territory of the munitions field warehouse on February 18, 2016 of a military unit located near the settlement of Grodivka of Donetsk region (use by a UAV enemy, who in turn dropped the packet with incendiary mixture on the ammunition stack); the fire that occurred on February 17, 2016 as a result of the dropping of incendiary and fragmentation ammunition from the UAV over the rear control post of the military unit (Zaporizhzhia region, Kuibyshevsky district, Vershina village); fire that resulted from dropping explosive devices from UAVs on February 18, 2016 (Cherkasy village, Dnipropetrovsk region). The enemy still uses unmanned aerial vehicles to destroy the ammunition of the Armed Forces of Ukraine. The system of storage of missiles and ammunition in field artillery depots is a set of forces and means, as well as measures of organizational, economic, legal, social and scientific-technical character, aimed at maintaining stable functioning and preventing explosions and fires and losses from them in storage sites and explosives.
