Abstract: A method for gripping an object by another gripping object comprises the steps of: detaching a part of an object to be gripped while maintaining a mechanical link; retaining the detachable part at a distance “a” from the object to be gripped by a part of the gripping object by spatial movement of the latter. At least a certain time period before the moment of engagement, there is the step of stabilizing an angle position of the detachable part relative to the object to be gripped by rotating said part to provide it with own angular momentum directed at an angle “?” to the object to be gripped. A reactive force F and/or an aerodynamic force R are (is) used as the retaining force. At the same time, the aerodynamic force R is generated by rotation of the detachable part. The rotating detachable part is oriented relative to the object to be gripped by generating an orienting aerodynamic force P on said part, said orienting aerodynamic force being directed at an angle to the object to be gripped.

Abstract: The invention relates to the rocket and space engineering, and can find use in development of reusable rocket complexes for placing various space objects in orbit. A set of rocket boosters for operating launch vehicles comprises expendable and nonexpendable rocket boosters. A part of equipment of the expendable booster and a part of equipment of the nonexpendable boosters are replaceably mounted on said boosters and are capable to be interchangeable. A part of interchangeable equipment is made interconnected to another part of said equipment by at least a part of communications and structurally united into a module by a housing of a compartment of boosters. A method of operating launch vehicles comprises the steps of one-time using an expendable rocket booster within the launch vehicle, and reusing nonexpendable rocket boosters within the launch vehicles.
