Abstract. The features of the development of domestic unmanned aerial vehicles are given. The main problems of the technological evolution of cargo quadrocopters have been revealed. The concept of the development of unmanned cargo multi-purpose multi-propeller flying aircraft is presented, reflecting the system of using a hydraulic transmission using the example of a quadcopter. The issues of accuracy, stability, controllability of the automatic control system and regulation of the hydraulic transmission of a cargo quadcopter are considered. A possible description of the hydraulic drive of the quadrocopter rotors as an object of regulation is presented. The forces acting on the quadcopter in flight have been determined. The controlling, disturbing and corrective effects on the automatic control and regulation system of the hydraulic transmission of the quadcopter are identified and described. The analysis of the possibility of using aircraft piston engines to drive the transmission of a cargo quadcopter, volumetric axial plunger pumps and hydraulic motors has been performed. New circuit solutions for hydromechanical devices for correcting static and dynamic characteristics are shown. Schematic solutions of hydraulic transmission regulators are presented: pressure regulator, dynamic pressure regulator, speed regulator, power regulator, LS regulator. The advantages of using regulators are described. The proposed hydro–mechanical controller with LS-regulation makes it possible to improve flight stability and energy efficiency of a multi-rotor aircraft.

Keywords: cargo quadcopter, hydraulic transmission, transmission control system, hydromechanical regulators of characteristics.

Abstract. Despite the development of assistive technologies, visually impaired students (VIS) continue to face issues when learning English. Most of the research explores the role of technology and materials adaptation in teaching English to VIS; however, there is a lack of research focusing on development of methods and approaches specifically designed for online education of blind students. Our research aims to address this gap by describing the methods, approaches and adaption of materials used to teach online English as a second language to visually impaired master’s students in an inclusive setting at ITMO University. We found strong evidence supporting the effectiveness of collaborative activities in inclusive education and adapted this idea for our online course, in which we successfully addressed several challenges identified in the literature, notably problems with fostering blind students’ autonomy. The article provides examples of online collaborative activities, the analysis of the most common VIS mistakes and tips for online teaching VIS vocabulary, grammar and four language skills.

Keywords: visually impaired students, assistive technologies, online education, distant learning, inclusive setting, teaching strategies, ESL (English as a second language), accessibility, collaborative activities, educational materials, teacher training, adaptation of teaching materials, teaching language skills.

Abstract. This paper presents a study of the variable camber morphing wing parameters influence on aerodynamic performance. A comparison of traditional plain flaps and slats (nose flaps) with variable camber morphing wing elements was performed. Numerical simulations were conducted using the XFLR5 software suite implementing XFOIL algorithms. The analysis was performed for a wide range of configurations and conditions, including variations in the rotation axis (hinge) position of the high-lift devices along the wing chord, and a broad range of deployment and angle-of-attack values. The key factors influencing the effectiveness of morphing high-lift devices have been identified.

Keywords: aerodynamics, morphing wing, plain flap, nose flap, high-lift devices.

Abstract. This article is devoted to the identification and analysis of strategies used in the localization of news articles on the Journal du Cameroun website (Republic of Cameroon) from French to English. When localizing the text of the article, the cultural characteristics of the audience receiving the text and the relationship between verbal and non-verbal signs are taken into account. The leading localization strategies are the domestication and the foreignization; the information restriction strategy acts as an additional strategy. In the process of localization, the interaction of these strategies is being observed. The analysis of the verbal component revealed the dominance of the domestication strategy. The information restriction strategy, which is associated with a significant reduction in the original text and its abstraction, is much less observed. When updating this strategy, the unnecessary details or the clarifications of the original article are eliminated, and the foreign-language recipient receives the most important, relevant and reliable information.

When localizing articles, the authors revealed the transformation at the level of multimodal elements, the photos are replaced, the number of photos is changed, or the visual element is completely removed. The pictorial material of the original French-language articles is being transcreated: the images are replaced completely or simplified, and the low-quality photos are replaced with higher-quality ones.

Keywords: localization, translation, domestication strategy, foreignization strategy, information restriction strategy, localization of visual elements.

Abstract. The paper analyzes speaker voice identification methods that are widely used in the practice of flight accidents investigation by speech recorded in the cockpit of a moving aircraft during an emergency situation on board. The advantages and disadvantages of each of methods are described, the factors reducing the reliability of the identification are indicated, and the methodological foundations for using utterances of persons recorded on a phonogram, whose attribution has already been established as an additional data source, are formulated. The prerequisites for constructing a step-by-step methodology for attributing utterances of persons recorded in the cockpit of a moving aircraft using the latest achievements in the field of forensic examination of audio recordings are given.

Keywords: aircraft, emergency situation, forensic speaker voice identification, flight accidents investigation.
