“…Метафоризация также присуща авиатерминологии: так, привычные слова: 'nose' (conical noseнос в форме конуса), 'wing' , 'tail' , 'body' , которые обозначают части тела (туловища птиц, животных), одновременно являются частью самолета: "….backward pressure raises the elevator, raising the nose and lowering the tail" [15], [16] (обратное давление поднимает руль высоты, поднимая нос и опуская хвост); "Most planes feature an enclosed body (fuselage) to house the crew, passengers, and cargo…" [19] (Большинство самолётов имеют закрытый корпус (фюзеляж) для размещения эки-пажа….). Словосочетание 'the air-breathing aircraft' (воздушное судно) ассоциируется с живым организмом, способным к самостоятельному дыханию из-за слова 'breathing' , что может вызвать затруднения при переводе.…”

“…Отметим необходимость использования семантической замены с целью свершения логических преобразований для достижения эквивалентного перевода: skin friction (сопротивление обшивки), trailing edge (задняя кромка), the lift-to-drag ratio (подъёмная сила) [16], например: "The ailerons are movable surfaces hinged to the trailing edge of each wing, which move in the opposite direction to control movement around the aircraft's longitudinal axis" [16]. -Элероны представляют собой подвижные поверхности, шарнирно прикреплённые к задней кромке каждого крыла, которые перемещаются в противоположном направлении для управления движением вокруг продольной оси самолета; "Results show that the increase of the design Mach number does negative impact on the lift-todrag ratio" (Результаты показывают, что увеличение расчётного числа Маха отрицательно сказывается на подъёмной силе) [19].…”

The article discusses the lexical and structural characteristics of aviation terminology and the methods of its translation into Russian, the features of terminology functioning, and the specifics of translation. A scientific and technical text is presented as a communicative unit, a source of replenishment and knowledge exchange between professionals of a certain field of science and technology, a synthesis of the scientific and the technical; both linguistic and extralinguistic factors are considered. Linguists’ points of view regarding the characteristics of scientific and technical texts are taken into account. The goal of this paper is to study the functioning of aviation terminology and the ways of its translation into Russian. A scientific and technical text is considered as the sphere with specific terminological units, and names of processes and phenomena, however, the consistent and logical nature of the presentation of the subject matter in a scientific and technical text does not exclude the presence of such lexical units as neologisms, phraseological units, vocabulary of foreign origin, abbreviations and acronyms. Aviation technologies abbreviations are full-fledged lexical units used as a means to economize linguistic means and as part and parcel of a technical text. The difficulties connected with the stylistic, lexical and syntactic features of the scientific and technical text are associated with the use of passive constructions, inversions typical of the analytical English language. Metaphorical means are identified as a source of terminology, which is proved by the adduced examples. Finding translation solutions when transferring the meanings of aviation terminology, and the selection of the required equivalent is the primary task of a full-fledged translation and an urgent problem of modern translation studies. The main task of the translator, who is not an expert in aviation technologies, when transferring the meanings of the term from English into Russian, is to achieve maximum semantic adequacy in translation. The difficulties encountered by the translator when translating aviation texts containing differently-structured terminological units are considered; the difficulties of translation are attributed to the absence of an equivalent in the translating language and may also be connected with determining the referent for designating the object in question, or may be associated with the syntactic difference between the English (analytical) and the Russian (synthetic) languages. The processing of language material makes it possible to determine the characteristic structural types of terminological units and to identify the most appropriate techniques of translation, such as formal, lexical and grammatical, in order to select the most appropriate equivalent to achieve a full-fledged translation option.

“…Hypersonic vehicles [1,2], the propulsion systems of which can be scramjets [3][4][5][6], combined cycle [7][8][9][10], or pre-cooled engines [11], are designed for commercial applications and military missions [12] in or across the atmosphere. These advanced vehicles demand a substantial and indispensable supply of electrical power to realize functions such as fuel feeding [13], radar detection, flight control [14], and potentially electromagnetic weapons [15].…”

Closed-Brayton-cycle (CBC) is a potential scheme to provide high-power electricity for hypersonic vehicles, but finite cold source onboard limits its power level. A thermoelectric generator (TEG) combined with CBC is a feasible power enhancement approach by extending the available temperature range of cold source. In this study, a performance assessment of the CBC-TEG combined power generation system coupled with hydrocarbon-fueled scramjet is performed to exhibit its possible operation characteristics and performance limitations on hypersonic vehicles. Results indicate that, at a fixed flight Mach number, a larger fuel equivalence ratio (φ) leads to a higher total electric power and CBC power but a lower TEG power. There are three limitations on the fuel equivalence ratio, TEG temperature difference, and combustion heat dissipation adjustment for the operation of CBC-TEG. The total power of CBC-TEG can be adjusted by φ, but the adjustable range becomes smaller at higher Ma. The electric quantity at unit fuel mass increases with φ, mainly due to the higher thermoelectric conversion efficiency. Moreover, the maximum value of the electric quantity at unit fuel mass for CBC-TEG reaches 277.0 kJ/kg, which is about 33.4% higher than that of standalone CBC.

“…The aerodynamic performance shapes of supersonic aircraft are generally divided into four categories: lift body, symmetrical body of revolution, blended wing body, and waverider. The waverider configuration is widely used in hypersonic vehicles with its good lift-to-drag ratio aerodynamic performance [1][2][3][4][5][6][7][8]. With the development of the research on hypersonic vehicles, the research on the waverider has gradually become one of the hotspots.…”

The waverider is widely used in hypersonic vehicles with its high aerodynamic performance, but due to the serious aerothermal environment, its sharp leading edge should be blunted. Circular blunt is one of the commonly used aerothermal characteristic protection methods. Circular blunt with larger diameter can reduce peak heat flux, but at the same time, it will lead to larger drag. The existing research shows that under the same blunt diameter in two-dimensions, the non-uniform blunt can reduce the peak heat flux by 20%, and the difference of drag is small. In this paper, the non-uniform blunt profile is applied to the three-dimensional waverider, and the influence of the non-uniform blunt profile on the aerothermal characteristic performance and aerodynamic performance of the waverider is studied, and the results are compared with those of circular blunt. The numerical simulation is used to compare and analyze the waverider under different angles of attack, flight altitudes, and Mach number. The results show that the peak heat flux of the waverider with non-uniform blunt reduces by about 17% compared with that with circular blunt under a small angle of attack range, Mach 2-10, and a flight altitude of 15–35 km. Meanwhile, when the blunt height/diameter is 20 mm, the aerodynamic performance difference between the two different blunt profiles does not exceed 3% within a 15 degrees angle of attack, Mach 2-10, and flight altitude of 15–35 km. The non-uniform blunt profile can be applied to the design of the three-dimensional waverider.
