Title: Роторный двигатель внутреннего сгорания "БЕСШАТУННЫЙ"
Inventor: ENOV MIKHAIL IVANOVICH
IPC: F02B57/08
Filed: 2019-04-23
Granted: 2020-08-19
Abstract: Изобретение относится к области двигателестроения, а именно к бесшатунным двигателям внутреннего сгорания. Техническим результатом является повышение удельных параметров и надежности. Сущность изобретения заключается в том, что в цилиндрической полости корпуса двигателя помещается цилиндрический ротор, в котором по диаметру выполнены два цилиндрических отверстия под углом 90 градусов друг к другу с размещенными в них двумя парами стыкующихся поршней, соединенных жестко с ползунами. Ползуны сидят свободно на эксцентриках двухэксцентрикового вала, который установлен свободно на коленчатой шейке вала отбора мощности, соединенного с ротором шестернями при соотношении их диаметров 1:2. Большая шестерня с внутренними зубьями закреплена на роторе, а меньшая в два раза шестерня с наружными зубьями жестко соединена с валом отбора мощности. Шестерни соединены между собой через две промежуточные шестерни с наружными зубьями, которые по диаметру в два раза меньше небольшой шестерни вала отбора мощности и располагаются с разных сторон задней торцевой крышки ротора, и это обеспечивает вращение ротора и вала отбора мощности в соотношении 2:1 в разных направлениях. Двигатель работает по 6-тактному циклу, и число его рабочих тактов равно 4, как в 4-цилиндровом 4-тактном двигателе внутреннего сгорания. А отсутствие в нем радиального цилиндрического кольца ротора упрощает конструкцию двигателя и облегчает его сборку. Применение в нем ползунов, снабженных антифрикционными накладками, значительно повышает его долговечность по сравнению с существующими 4-цилиндровыми двигателями внутреннего сгорания. 3 ил.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to experimental surgery, and can be used for assessment of scaffolds angiogenic potential. Scaffold is implanted in the form of a disc under the skin of rats, after which blood is sampled in amount of 3–5 ml under anaesthesia. Blood is centrifuged to produce serum in which the concentration of vascular endothelium growth factor A-VEGF is determined. Blood is sampled 7 days after implantation. Additionally, serum concentration of syndecan-1 is determined. Ratio of VEGF to syndecan-1 is calculated. For normalization of the ratio of concentrations of VEGF and syndecan-1, it is multiplied by a correction factor K, defined as the ratio of median values of syndecan-1 and VEGF concentrations in intact animals. If normalized value of ratio of concentrations of VEGF and syndecan-1 does not exceed 2, then matrices do not have angiogenic potential. If the ratio is more than 2, then the matrices have an angiogenic potential. 
     EFFECT: method provides more accurate assessment of the angiogenic potential of the biodegradable scaffold at the early stages of a subcutaneous implantation test by using a combination of angiogenesis induction marker concentration and endothelial glycocalyx stability, which makes it possible to characterize intensity and direction of structural remodeling microcirculatory channel.

In the second method, in the process of smoothing the obtained orientation angles, angular speeds are used, recalculated into the coordinate system in which the orientation angles are measured. The third method uses the speed obtained, for example, on the basis of a flight task (setting the speed programmatically). In the fourth method, both the program value of the A speed is used to form the orientation angles, and the values of the angular speeds converted into the coordinate system in which the orientation angles are measured, to smooth out the obtained orientation angles. These methods are implemented using the navigation system of the A, which contains: a computer, an accelerometer, a gyro sensor of angular speeds, a pendulum system consisting of a pendulum that is equipped with a swing angle sensor, and an airspeed sensor.
