Abstract

The invention relates to rocket and space technology. A reusable rocket stage, after separating from a carrier rocket, uses engines as a means of braking, and descends to a landing point, where a platform is located. Hovering at a height of approximately 15-20 meters above the platform, the engines turn off and the stage free-falls onto the platform. The integrity of the descending stage is maintained by virtue of shock-absorbing characteristics of the platform, which dampens the momentum of the fall. The present landing method makes it possible to avoid a series of negative factors which are inevitable in traditional vertical landing, such as the effects of weather and the malfunctioning of the stage engines, and also eliminates the need for any mechanisms in the form of supports, thus decreasing the weight of the carrier rocket.

Description

СИСТЕМА МЯГКОЙ ПОСАДКИ МНОГОРАЗОВОЙ РАКЕТНОЙ СТУПЕНИ  SOFT LANDING SYSTEM FOR REUSABLE MISSILES
Изобретение относится к космической технике .Система мягкой посадки многоразовой ракетной ступени содержит в себе ракетные двигатели и мягкую платформу для осуществления самой посадки .Нет ни парашютной системы ни каких бы то ни было механических опор как на самой ступени , так и на платформе .И это принципиальное отличие данной системы от других. Торможением двигателей достигается зависание ступени в The invention relates to space technology. The soft landing system of a reusable rocket stage contains rocket engines and a soft platform for the implementation of the landing itself. There is no parachute system, no mechanical supports of any kind, either at the stage itself or on the platform. And this is fundamental difference of this system from others. Deceleration of the engine is achieved by hanging the stage in
определенной точке на определенной высоте над платформой .После этого двигатели выключаются и ступень спокойно падает на платформу a certain point at a certain height above the platform. After that, the engines are turned off and the stage quietly falls on the platform
.Целостность и сохранность ступени достигается мягкостью самой .Integrity and safety of the stage is achieved by the softness itself.
платформы .Т.е. платформа амортизирует и тем самым гасит импульс падения. Выключение двигателей над платформой обусловлено platforms .Te the platform absorbs and thereby dampens the momentum of the fall. Shutdown engines above the platform due to
необходимостью предохранить платформу от попадания огня от работающих двигателей . the need to protect the platform from fire from operating engines.
Известна система посадки -это система посадки первой ступени ракеты «Falcon», которая осуществляется при помощи механических опор на автономную плавучую платформу . A known landing system is the landing system of the first stage of the Falcon rocket, which is carried out by means of mechanical supports on an autonomous floating platform.
(http://rbcdaily.ru/industry/562949993665236). А так же другие системы посадки , см.патент РФ 2497715 и патент US8678321 В2.  (http://rbcdaily.ru/industry/562949993665236). As well as other landing systems, see RF patent 2497715 and patent US8678321 B2.
Посадка ступени с помощью механических опор на жесткую поверхность имеет ряд недостатков .А именно : возможность опрокидывания ступени ракеты-носителя при нерасчетных условиях ее посадки в части скорости посадки, ее вертикальной и горизонтальной составляющих, неровностей поверхности (углублений и выступов), а также случайных порывов ветра. Затрачивается масса усилий для удержания самой платформы в равновесном положении , для получения максимально ровной поверхности .Наличие на ступени механизмов в виде опор - увеличивает вес ступени , что ведет к увеличению расхода топлива . Landing steps using mechanical supports on a rigid surface has several drawbacks. Namely: the possibility of tilting the launch vehicle stage under odd conditions of its landing in part of the landing speed, its vertical and horizontal components, surface irregularities (recesses and projections), as well as random gusts wind A lot of effort is expended to keep the platform itself in an equilibrium position, to obtain the most even surface. The presence of mechanisms on the step in the form of supports increases the weight of the step, which leads to an increase in fuel consumption.
Целью изобретения является устранение указанных недостатков. The aim of the invention is to eliminate these disadvantages.
Указанная цель достигается конструкцией платформы и способом This goal is achieved by the design of the platform and the way
приземления .Платформа состоит из мягкого амортизирующего материала .Например из пенополистирола (пенопласта)Блоки пенопласта укладываются рядами , прокладываются синтетической сеткой .Несколько слоев уложенных друг на друга и составляют платформу . Landings. The platform consists of a soft cushioning material. For example, polystyrene foam (foam). The foam blocks are stacked in rows, laid with a synthetic mesh. Several layers are stacked on top of each other and make up the platform.
ЗАМЕНЯЮ ИЙ ЛИСТ ПРАВИЛО 26 Количество слоев пенопласта ,а так же размеры самой платформы определяются и зависят от массы приземляемой ступени и точности приземления . Что бы платформа не сгорела от пламени работающих двигателей , двигатели должны быть выключены на некотором юптимальном расстоянии от платформы. Высота на которой отключаются двигатели ступени должна быть как можно ниже , но тем не менее такая, при которой пламя от двигателей не попадало бы на платформу .После чего происходит свободное падение ступени на платформу. Платформа может располагаться как на суше так и на море . REPLACE THE SHEET RULE 26 The number of foam layers, as well as the dimensions of the platform itself are determined and depend on the weight of the landing stage and the accuracy of the landing. In order for the platform not to burn from the flames of the working engines, the engines must be turned off at a certain optimal distance from the platform. The height at which the stage motors are turned off should be as low as possible, but nonetheless one at which the flame from the engines would not fall on the platform. The platform can be located both on land and at sea.
