RU2150411C1 - Multistage rocket for change of trajectory of motion of asteroid - Google Patents

Abstract

FIELD: rocketry and space engineering; transfer of asteroid to orbit safe Earth. SUBSTANCE: rocket has liquid- propellant rocket engines, stabilizer and instrument section with control system. Rocket consists of three parts: front and rear parts and burnable head fairing. Rear part contains above-mentioned engines. Front part is used for reverse braking at approaching the asteroid. It has bell mouth provided with holes over circumference for escape of gases of rocket engines. Burnable head fairing closes these holes of bell mouth. Rocket engines of front part have lesser thrust power; these engines are used for exhaust of gases only during period of change of asteroid orbit. EFFECT: repulsion of asteroid from rocket and transfer of it to orbit safe for Earth. 2 dwg

Description

 The invention relates to rocket and space technology and is intended to change the trajectory of the asteroid with its transfer to a safe orbit for the Earth.

 As you know, small planets (asteroids) are bodies of the solar system with a diameter of 1 to 1000 km. The mass of all minor planets (mp) is less than 1/700 of the mass of the Earth. Orbits of the majority of metro are between the orbits of Mars and Jupiter (the so-called asteroid belt). The most famous of them: Ceres (N 1), Pallas (N 2), Vesta (N 3), Juno (N 4), Eros, Cupid, Gidalgo, Icarus.

 More recently (1992 - 1994), a message was published stating that an asteroid is moving toward Earth. After some time (several weeks) another message was published, more favorable, that the asteroid flew past planet Earth.

 And finally, on September 28, 1996 at 14:05 (Magnitogorsk time) on the ORT television channel in the program “Obvious Incredible”, a message was made that a symposium of scientists was held, at which reports and recommendations regarding possible “visits” were made Earth asteroid and that in this case it is necessary to launch an asteroid by launching a rocket. Apparently, no assumptions were made about what would happen after this and after that with the asteroid. However, if many fragments of the asteroid fall to Earth, then this will be undesirable.

 Reflections of this order lead to a different solution: to modernize the rocket in order to change the flight path (movement) of the asteroid without explosion.

 Known rocket equipped with a brake engine that allows a soft landing on the planet (see, for example, source: Cosmonautics. Encyclopedia. Edited by Glushko VP - M .: Sov. Encyclopedia, 1985, article "Braking rocket engine" , p. 400). However, this device does not allow to solve the problem of changing the trajectory of the asteroid.

 The closest analogue of the invention is a multi-stage rocket containing liquid rocket engines with fuel and oxidizer tanks, a stabilizer and an instrument compartment with control system equipment (see ibid., Article "Rocket"; p. 320).

 However, the known rocket also does not have sufficient means to change the orbit of the asteroid.

 The objective of the invention is to provide a means by which an asteroid would be repelled from a rocket and transferred to a safe trajectory for the Earth.

 This problem is solved in that a multi-stage rocket is made of three parts: the rear part, which includes the indicated liquid rocket engines, a stabilizer and an instrument compartment, the front part of the reverse braking action with rocket engines and a bell, in which holes are made around the circumference for the exit of rocket gases engines, and a combustible head fairing that covers the indicated holes of the socket, moreover, the rocket engines of the front of the rocket are made with less traction power and are designed to select yvaniya gas only during the repulsion of the asteroid to a safe path for the motion of the Earth.

The invention is illustrated by drawings, where:
in FIG. Figures 1 and 2 below: launch of a rocket consisting of three parts (1, 2, and 3); while the crosses are conventionally designated rocket launchers.

 At the top are two parts of the rocket (1 and 2 - double-acting) when the gas flare is ejected from the rear part (1) of the rocket and the gas flare is ejected (5) from the front of the rocket (2).

 A double-acting rocket (or a group of rockets) is intended to change the trajectory 4 of asteroid 7 flying to Earth 8. At the same time, it is proposed to change the trajectory of the asteroid so that it does not fall to Earth, but flies past our planet. Each of the missiles contains three main parts: the rear, made in the form of a multi-stage launch vehicle with all the necessary components: traction rocket engines, a fuel tank, an oxidizer tank, an instrument compartment with remote control equipment and other elements, and a front part 2, made adjoined rigidly to the rear part 1. In this case, the front part 2 is made with a fairing head 3, inside of which a damper device can be rigidly fixed to the socket of the brake engines of the front part of the rocket in the form of, for example, a spiral spring. The bell around the circumference is provided with openings for the exit of gases of the brake engines and to weaken their action. A damper device may be necessary for smooth docking with an asteroid.

 The number of rockets in the group (Fig. 2) is determined by the size of asteroid 7, which is conventionally designated as a spherical body. In this case, the rear part 1 of the rocket also emits slightly more thrust gases and holds the double-acting rocket (1, 2) near the asteroid 7 in the working (pushing) state.

 The head fairing 3 inside contains igniters of rocket fuel for its ignition when approaching the asteroid 7. After that, the fairing either burns out or is discarded.

 When using a device (a group of double-acting rockets) to accomplish the aforementioned task, it is necessary that the longitudinal axis of the central double-acting rocket (1, 2, 3) and the entire group of these rockets and the gas flares of their traction engines be directed to asteroid 7 under the optimal an acute angle relative to the initial trajectory 4 of the movement of the asteroid to change it into a new trajectory 6.

 The rear part 1 of the rocket (or rockets) will play a holding role near the asteroid for as long as the task of deflecting the asteroid from the flight path to the Earth requires.
