Title: Method of control of spacecraft turn and system for realization of this method
Inventor: LEVSKIJ M V
IPC: B64G1/24
Filed: 1997-06-24
Granted: 1998-07-10
Abstract: FIELD: shift of spacecraft from any initial attitude to preset final attitude within preset period of time. SUBSTANCE: proposed method is used for realizing the turn of spacecraft over free motion trajectory. Direction of moment of momentum of spacecraft remains constant relative to absolute space during entire period of turn. High accuracy in position and time of completion of turn will be ensured due to estimation of expected time of completion of manoeuvre which is compared with preset time of turn; according to results of comparison, rated magnitude of vector of moment of momentum is corrected and is noted in inertial basis; upon completion of action of boosting impulse, control moment is formed and is applied according to measured parameters of angular motion of spacecraft to ensure motion of spacecraft at rated moment of momentum; deceleration of spacecraft is started from the moment when time required for corrective turn spacecraft till final attitude is equal to time for damping present moment of momentum. System used for realization of this method automatically determines parameters of trajectory. EFFECT: enhanced accuracy. 5 cl, 13 dwg

Abstract: Изобретение относится к области машиностроения, а именно к подшипниковым узлам. Подшипник содержит пару трения, состоящую из внешней втулки, установленной в корпусе, и внутренней втулки, расположенной на валу и имеющей продольное сечение в виде трапеции, при этом конические торцы внутренней втулки взаимодействуют с сопрягаемыми коническими поверхностями сжимающих деталей. Одна сжимающая деталь поджата к одному из торцов внутренней втулки гайкой. Внешняя втулка запрессована в корпус, сжимающая внутреннюю втулку деталь выполнена упругой, а большее основание указанной трапеции внутренней втулки обращено к валу. И внешняя, и внутренняя втулки выполнены из твердого износостойкого антифрикционного материала с низкой прочностью на растяжение и высокой прочностью на сжатие, например из силицированного графита. Внутренняя втулка состоит из двух частей, между которыми установлено промежуточное кольцо из материала, имеющего высокую прочность на растяжение, например из стали, с радиальными отверстиями для подачи смазывающей жидкости и лысками для создания гидравлического клина. Сжимающие внутреннюю втулку по торцам детали имеют углы наклона торцов к оси вала меньше, чем соответствующие углы наклона торцов внутренней втулки. Между внутренней втулкой и валом имеется зазор, заполненный полимеризующимся материалом, которым покрыты также торцы внутренней втулки и сопряженных с ней сжимающих деталей, а последние закреплены на валу. Один торец внешней втулки опирается на буртик корпуса, а второй - на ответное кольцо, запрессованное в обойму. Технический результат - повышение ресурса подшипника скольжения. 4 з.п. ф-лы, 1 ил.
