Description

The invention relates to the field of armaments and can be used in rocket technology and artillery.

Known radio-controlled rocket complex "Crotal", selected by us as a prototype, containing a housing, an engine, aerodynamic stabilizers on the housing, radio antennas on the stabilizers and radio control equipment inside the housing [1].

The disadvantage of the device is as follows: the radio antennas located on the wings are subject to the action of the incoming air flow, especially at angles of attack that occur during control. The effect of the oncoming air flow on the rocket elements is proportional to the square of its speed. When flying in dense layers of the atmosphere at a speed exceeding 1300 m / s, the action of the oncoming air flow leads to kinetic heating of the hull elements to temperatures of 1000 ° C or more, especially on its protruding elements. Therefore, during the flight of such a rocket in dense layers of the atmosphere with a speed exceeding 1300 m / s, intense heating of the antennas will occur, which after some time will lead to a disruption in their performance and the termination of controlled flight. The flight time of such a rocket in dense layers of the atmosphere at ultrahigh speeds is limited.

In addition, the device cannot be used in artillery, when firing cannons with an active shot.

The objective of the invention is the creation of a projectile, the design of which will allow its stable management when flying at ultrahigh speeds in dense layers of the atmosphere and ensuring its use in artillery

This task is achieved by the fact that in the known radio-controlled projectile containing a housing with an aerodynamic stabilizer, radio equipment with an antenna, an accelerating engine, the aft of the projectile is equipped with a detachable, mainly pyrotechnic, assembly, a pallet located in the aft of the projectile, and in the pallet from the rear end the shell is made a cavity, the antenna is made in the form of a waveguide, one end of which is connected to the output of the radio equipment, and the other end is located outside the shell and placed behind the aerodynamics cal stabilizer portion of the waveguide placed in the cavity of the pallet and provided with throttle-flange, to which a waveguide is set from the radio dielectric tip, and for the throttle-flange connection waveguide is mechanically connected to the pallet.

The essence of the invention lies in the fact that this device allows during operation of the accelerating engine, which is up to 20% of the main time, to transmit control commands over the air through the external input of the antenna and the antenna part weakly protected from air flow works for a short time, and after the engine runs, the pallet, together with part of the antenna, is separated before being connected to the waveguide and commands are transmitted and received through the remaining part of the waveguide and the dielectric tip (provides radiation directivity), which are located at the end of the projectile and are protected from the action of the air stream, are therefore not subject to kinetic heating. The presence of a pallet provides firing a projectile from cannons while providing acceleration with an active shot.

The device and principles of operation of a radio-controlled projectile is as follows: a radio-controlled projectile consists of a body 1 with an aerodynamic stabilizer 2 and radio equipment 3 with an antenna consisting of two parts, one of which 4 is located inside the projectile and the other 8 outside, and the accelerating engine 5. Stern part of the projectile is provided with a detachable pallet 7 provided with a cavity A connected to the second part of the antenna, one end of which is connected to the output of the first part of the antenna by a detachable flange-throttle connection 9, and the other is placed behind the aerodynamic stabilizer, before connecting the antenna parts to the waveguide from the side of the radio equipment, a dielectric tip 10 is installed.

When the projectile starts, the engine runs, accelerating the projectile to the required speed. Its operating time is up to 20% of the projectile flight time. Control commands are transmitted over the air via an external antenna. After the booster engine is finished, the pallet and the outdoor antenna are separated, opening the antenna output at the rear end of the projectile, through which radio signals are transmitted in the remaining section, until the controlled flight ceases.

Thus, the proposed device ensures the operability of radio control equipment during the flight of a projectile in dense layers of the atmosphere by ensuring the operability of the antenna, and also provides active acceleration of the projectile when firing from guns.
