METHOD FOR RESCUE OF STAGE OF AIRCRAFT APPARATUS ON TRAJECTORY OF LOWERING IN ATMOSPHERE AND DEVICE FOR ITS IMPLEMENTATION

This invention relates to the crafts lowering in atmosphere. The method for saving a stage of a craft at the trajectory of lowering in atmosphere is in application of retardation pulse by aerodynamical appliances connected to the craft by non-rigid elements. After the craft falls into atmosphere the non-rigid elements, for instance, ropes, are released from intermediate links with the body. The body is separated to sections previously connected by that ropes, for instance, by means of elongated cumulative charges, with formation of a system of sections connected by ropes and stable with respect to the vector of velocity of falling flow. The shape and the mass of the sections is chosen in such a way that ballistic coefficient of the last of those in direction of flight is the largest, and the lengths of the ropes are chosen from the condition of the sections not being in aerodynamical shadow. The appliance for implementation of the method includes separable stage of a rocket and non-rigid elements attached to it. On the housing and the inner elements of the structure in contours formed by cross-section of those with the separation surfaces elongated cumulative charges are installed. At the side surface of the housing of the stage, at both sides of the charges, near those, uniformly in perimeter of the stage, along its generatrixes, there are installed the nodes for fixation of the opposite ends of each of the ropes, the ropes themselves are laid along the generatrixes and tightened, by loops, by means of carbines, to rings attached to the housing by pyro-bolts. Between the nodes of fixation of the opposite ends of each of the ropes there are installed, with tension, protective arc-like springs, with the convex part to outside of the housing; at the outer surface of each of those there are provided troughs for the ropes on which those are laid with tension. The pyro-bolts and the charges are electrically connected to the program-time device. This invention provides high reliability and safety of use of the stage, and quick switching it to the mode of deceleration.
