Description

The invention relates to the field of aerospace rocket and space technology. It can be used in space-based aeronautical missile systems (ARC KN), for example, with heavy ballistic carrier rockets (LV) weighing 100 tons or more, equipped with, for example, liquid-propellant rocket engines (LRE) and launched in the air, with the aim of launching spacecraft (SC), for example, a satellite, in orbit. In this case, the delivery of the launch vehicle to the launch area is provided by a glider towed by an airplane.

Known AR KN with a heavy ballistic launch vehicle, located inside the fuselage of a glider towed by an airplane.

The main disadvantage of the aforementioned aerospace missile system for space purposes is the limitation on the maximum initial launch vehicle mass and, as a result, the restrictions on the maximum mass of spacecraft launched into orbits.

The main tasks to be solved by the invention are:

- an increase in the mass of the spacecraft launched into orbits,

- improving the safety and reliability of the aircraft, glider, equipped with LV, during takeoff,

- a significant reduction in the cost of creating an ARC with enhanced technical characteristics, as well as the timing of its development.

This is achieved by including in the ARC additional aircraft and towing rope-halyard in comparison with the prototype. The inclusion of additional aircraft and a towing rope-hitch allows you to increase the force required for transportation on a transport-booster platform (TRP) of a glider placed inside its LV with an increased initial mass on the ground during take-off and flight to the launch area.

As the base aircraft, which can be taken as the basis for the development of towing aircraft and TRP, existing spent heavy transport aircraft, for example, Il-76MT (MD, TF), modified for the conditions for their use in the ARC, can be taken. This will significantly increase the technical and economic efficiency of the ARC (including a significant reduction in the financial costs and terms of the creation of the ARC, increasing the safety of operation and technical characteristics of the ARC).

The invention is illustrated figure 1-3, which shows a General view of the placement of a glider with a booster rocket on a transport and boarding platform and its interface with aircraft that perform the functions of towing.

The glider 1 with the launch vehicle 2 is located on the TRP 3. The glider 1 is connected via a towing cable-halyard 4 to aircraft 5, the towing cable-halyard 6 is connected to planes 7 and 5.

This system - a glider 1 equipped with a launch vehicle 2, aircraft 5, 7, TRP 3 and towing ropes-halyards 4, 6 - operates as follows.

Before launching the spacecraft, the TRP 3 is fed to the technical position of the aviation missile complex, where it is loaded with a glider 1 equipped with a launch vehicle 2, for example, not filled with fuel components.

After loading the airframe 1 onto the TRP 3, the carrier rocket 2 is refueled and the systems of the carrier rocket 2 are checked, as well as the TRP 3 systems and 5.7 aircraft.

After the completion of all work on preparing the aviation missile system for launching the spacecraft (including glider 1, aircraft 5, 7, launch vehicle 2, TRP 3), the equipped TRP 3 is towed to the runway (runway) 8 to the start of the take-off run planes 5, 7 for take-off to launch rocket 2, where the aircraft 5 is engaged with the glider 1 using the towing rope-halyard 4 and with airplane 7 using the towing rope-halyard 6. As a result, planes 5, 7 and TRP 3 are given in runway start position 8.

The functioning of the complex is carried out in the following sequence.

On a command to take off to the missile launch area, engines are started simultaneously on planes 5, 7 and TRP 3 (for accelerating TRP 3, for example, engines 9 of the Il-76MT airplane (MD, MF) are installed on it). The thrust of the engines of aircraft 5, 7 and TRP 3 provide equal acceleration when moving along runway 8.

Upon reaching the specified levels of engine thrusts of towing aircraft 5, 7 and TRP 3, a take-off command is issued (the start of their movement along runway 8).

At the same time, the thrust levels of the engines of aircraft 5 and 7, engines 9 TRP 3 are provided, excluding the sagging of the halyard cables 4 and 6 to unacceptable values.

When airplanes 5, 7 and TRP 3 move along runway 8, lifting forces act on planes 5, 7 and glider 1, which ensure separation of planes 5 and 7 from runway 8 and glider 1 from TRP 3 when the desired speed is reached (280-300 km /hour).

After the separation of aircraft 5 and 7 from runway 8 at the same time from TRP 3, on command, for example, from the ARC control system (RN2 or TRP 3), glider 1 equipped with a launch vehicle 2 is separated and aircraft 5 and 7 begin to fly to the launch launch area 2. The launch of the launch vehicle 2 is made from the glider 1.

Thus, the technical appearance of the ARC presented above with new distinctive features in comparison with the prototype allows for lower financial costs and the time required to create the ARC with improved technical characteristics, for example, to significantly increase the mass of the spacecraft launched into orbits.

The technical solution proposed in the invention opens up a new direction in the creation of ARC means to ensure the take-off of gliders towed by airplanes, for example, for single use, equipped with LVs, and their delivery to the launch area.
