The present invention relates to the field of precision weapons (THAT) and it relates to the new varieties in the form of a hybrid rotating missiles (BP) and cruise missiles (CU). Currently known unmanaged BP with correction of their movement on the sighting angles (used, for example, in the reaction system volley fire "Tornado") and controlled BP: single rotating anti-aircraft missiles (VSWR), such as "stinger", "Arrow", "Needle", "Mistral" and other BP, such as anti-tank.

The history of the development of rockets for military purposes began during the 2nd world war, when German engineers have created the world's first rocket is equipped with navigation and automatic piloting V-2. After the war this area weapons got rapid development and were created by the missiles of various classes and purposes. Despite all their differences, the General principle of flight of all types of missiles is the formation of the jet thrust with thrust coefficient (CT) greater than unity (CT is the ratio of thrust starting weight). Thus, the rocket unlike the aircraft (AC) with other types of CT is less than one is not required to generate aerodynamic lift, and compensation of the force vector of gravity on the active part of its trajectory is due to the vertical component of the thrust vector, and the passive after vigor�of fuel to compensate for the force of gravity is no more and the rocket continues to move, but not moving up or horizontally on the course, and forward and down the parabola.

When developing any type of aircraft), including missiles, even at the stage of research and experimental design, in addition to task for unconditional support of the formation of lifting force before the developers get up many of the tasks of the search for technical solutions (TP), the most important of which are to ensure the stabilization of the angular positions at the start, the stabilization of the missile and control in flight without loss of stability of motion in all specified regular modes, taking into account all possible internal and external disturbances.

With the development of rocket technology and solutions to the identified problems from the standpoint of the mechanics of flight, principles of stability and controllability of the movement of all known missile, despite their apparent diversity, can be divided only into two groups: missiles with 6 degrees of free movement and missiles with 5 degrees of freedom is stabilized by the 6th rotation around the roll axis. Missiles with 6 degrees of freedom (let's call them non - HP) and BP differ significantly on the mechanics of motion, the principles of ensuring the stability and control of movement. HP are far more complex principles, more sophisticated stabilization system, automatic pelotero�tion, homing on the target, because of the need to stabilize angular positions around the 3 axes, roll, heading, and pitch and control the movement also 3-coordinates that requires a large number of control forces and moments. BP have a natural stabilization without the cost of technical means through gyrostabilizers momentum of the rotating body, and are managed much easier on one channel, so they are called single-channel.

The most extensive development and spread of HP, from heavy ballistic missiles to shoot small caliber, for different purposes and applications as carriers of nuclear weapons, cluster combat elements of individual homing missiles classes "ground-to-ground, air-to-air missiles, sea-based tactical missiles are part of the reconnaissance-strike complexes (HANDS), there are HP small, medium, and long range. From the variety of HP special significance cruise missiles (CU) - based and range. CU characterized by a high probability of hitting the wide range of goals, start CU virtually no modern means of fixed missile warning, and massive use of the CD even with conventional non-nuclear warhead (BC) p�formulating action is comparable to the use of nuclear weapons. However, all the known CU are performed with 6 degrees of freedom as HP and have therefore increased the complexity of stabilization systems and management and the high cost of technical means for implementing the methods of flight stabilization and control 6 degrees of freedom spatial movement, which in turn increases the cost, its own weight and dimensions of both the missiles and launchers).

Less well-known and have a limited scope of BP, mainly as small-caliber anti-aircraft missiles for firing at low-flying air targets and as anti-tank missiles. But BP have a number of significant advantages over HP: simplicity stabilization without the cost of technical equipment, single channel operation, a large margin of stability of motion in all modes of flight, small own weight and dimensions of both the missiles and PU.

Due to the lack of diversity BP as close TP to the applicant and the closest TP is a method of flight VSWR (1, 2). The known method of flight based on acceleration VSWR jet-thrust solid-propellant rocket engine with CT is greater than one, simultaneously twist around the axis of the roll and the stabilization of its spatial movement maintaining the rotation by gyrostabilizers momentum of the rotating body, single channel motion control cancer�s in rotation mode via synchronous in frequency and phase rotation change bookmarks rudders on the sign of the angle of attack. The known method of flight does not require the formation of aerodynamic lift, as the vertical component of the thrust vector sufficient for movement of the rocket at any angle up to 90°. However, this advantage has "reverse of the medal" while CT is not necessary to generate aerodynamic lift, but the more you pull, the greater the rate of combustion of the fuel, kratkovremennoe the active part of the trajectory and the smaller the radius of the missiles. In addition, in the solid fuel includes the oxidant, although for missiles not exceeding the limits of the atmosphere, the oxidizing agent can be on Board not to take, and pick it up from the atmosphere by setting the rotary rocket on the principle of normal winged HP compact disposable turbojet engine (OTRD). This will greatly increase the range of BP and to expand the scope of BP, for example, as a rotating CU (WRC), combining the advantages of BP, as the simplicity of the stabilization and control, small weight and size, with the advantages of cruise missiles, that is, the effectiveness of target at long range and secretive approach to the targets at low and very low altitudes outside the detection zone of the radar systems of the enemy.

The purpose of the claimed method of flight is to increase the flight distance and the expansion about�ASTA use BP. These goals are achieved in that in the method of flight BP, based on the acceleration of the rocket jet thrust, twist it around the roll axis and the stabilization of the rotation, single channel, the management mode of rotation through synchronous in frequency and phase rotation toggle bookmark rudders on the sign of the angle of attack, first spin and accelerates the missile to the primary speed with a solid propellant booster, and then maintain cruising speed quickly pull small OTRD, support mode of rotation is oblique relative to the longitudinal axis of the missile tail stabilizers or by using gas-dynamic nozzle on the nozzle OTRD and form an aerodynamic lift force in the rotation mode by simultaneous frequency and consistent for the total phase shift of n-pairs of compact folding wings, located at the corner of the roll increments of2πnand along the longitudinal axis of the missile - symmetrically relative to the center of mass of the discrete spiral with a twisting direction coinciding with the direction of rotation of the rocket.

Thus, stated in the TP method, a lifting force is formed by the thrust of the solid propellant upper stage engine on the parts of the trajectory, and then flying BP loss�goes through the formation of aerodynamic lift as expressly set forth above. This principle of development the lifting force in the rotation mode is currently unknown. It is the introduction to the proposed method of flight of this trait allows you to get the declared intermittent positive effects: sudden qualitative increase in flight distance BP and promising direction for further development of BP for their use as cruise missiles, long range while maintaining the stability of motion without the cost of technical means, compactness, small self-weight and caliber, the reduction of which is limited only by massogabaritnymi known OTRD. In the future, with the development of such WRC sufficiently small size and weight, they can be used in the composition of the reactive systems of volley fire WRC individual guidance to defeat the purposes of clusters of the enemy at long range. It is known that all BP operated in the mode of rotation, moving in a spiral at a zero coefficient command (CC), because the governing force vector rotates with the rocket, see (2). From supersonic aerodynamics it is known that the velocity of the rocket above the speed of sound in the bow at the point of its taper arise shock wave or the shock surface (shocks), whose dismissal from the rocket sharpening blunted and set spiral aerody�onicescu nozzle (adni). In addition, if the rocket an optical homing head (AFO), it is necessary not only to withdraw the shocks, but also to prevent heating of the fairing AFO, otherwise there will be interfering background infrared radiation, which can blind the infrared channel and score a useful signal from the target and even sophisticated filtering backgrounds will not help to isolate it. The rotation will help to solve these problems for VSWR "Needle", which has a cruising speed of 600 m/s, is successfully solved by the installation of the fairing AFO spiral adni. Thus, the WRC will get many advantages compared to conventional non-rotating CU. Thanks to a new combination of useful properties acquired at WRC will be possible to use two channels targeting, optical and radar, and the mechanical rotation may be used to scan the underlying surface of a simplified antenna without the phase grating. All these advantages due to the fact that spiral rotary motion, by its nature, has advantages over progressive and give developers more WRC rich possibilities of solving many design problems WRC, although the main and most important advantage of this method of flight in rotation mode is to ensure the stability of motion without the cost of hardware, which is very substantial in the field�e HP this factor ceteris paribus increases her weight and dimensions of known CU.

Fig.figure 1 shows the WRC, as one of the options for implementing the proposed method of flight BP; Fig.2 simplified block functional diagram for explaining the principle of operation of the rocket in terms of management and formation of aerodynamic lift in rotation mode.

Fig.1 marked: startup accelerator with 1 PAU 2; case 3 the primary stage of the rocket; small ATRD 4; DDT 5; folding the air intake 6; three pairs of folding of the wings 7, 8, 9; rudders 10; 11 adni.

Fig.2 marked: autopilot (AP) 1, combined with a navigation unit; a gyroscope 2-1 roll, which revolves around the sensor 2-2 reference signals; amplifiers 3, 4, 5, 6; actuators 11, 12, 13 of the wings 7, 8, 9; actuator 14 rudders 10 (for convenience, the numbering of the wings and rudders in Fig.1 and Fig.2 matches).

Method of flight WRC in Fig.1 and 2 operates as follows. In the initial state WRC fused, installed in the transport and launch container and passed preflight training, during which the memory of the navigation unit entered the coordinates for the target and the trajectory of approach to it. On the command "start" triggered lifting charge, WRC exits the launch tube, after which triggered the start of the accelerator 1, which accelerates the craft and at the same time spinning around h�making it around the roll axis due to the action on the jet DDT 2. After running out of fuel in the accelerator trigger pirozhki (in Fig.1 are not shown, since these are typical elements of any missiles) and the accelerator 1 is separated from the primary stage of WRC. After separation of the accelerator serves a command to unlock the folding of the air inlet 6, the folding of the wings 7, 8, 9 and rudders 10 and to run ATRD 4. Elements of the air inlet 6, the wings 7, 8, 9 and drive 10 out of the grooves and fixed in position. In accordance with flight instructions 1 AP begins to form single-channel control signal (CS), using the reference "meander" sign sinωt frequency of rotation ω of the rocket, t - time, and digital reference signal, a unitary impulse number code representing a single module of the vector of factor commands (CC) integral unit functions sinωt. Methods of forming the SU single-channel rotary rocket, see (3), see example of a sensor (4). SU with the AP 1 is supplied to the power amplifier 6 and then to the steering actuator 14. When the trajectory of the rocket, given in her memory flight instructions, the AP delivers the SU with zero components of the module and phase of the vector QC, and when WRC deviates from its trajectory, served QC, WRC returns to its trajectory. In either case, the wheels 10 are switched synchronously by the frequency and phase of rotation of the WRC is the sign of the angle of attack changes the switching law for sadhanamala and QC phase. Simultaneously, the sensor 2-2 orbiting gyroscope 2-1 roll, three reference forms "meander", shifted between each other in phase by 120° and an initial phase, i.e. the initial count corresponding vertical phase plane perfect wings (PEAK). These meanders are received at the inputs of the power amplifiers 3, 4, 5, and further to the actuators 11, 12, 13 of the wings 7, 8, 9, which are arranged along the longitudinal axis of the housing WRC symmetrically about its center of mass and discrete spiral with a shift angle of roll 120, the twisting direction which coincides with the direction of rotation of the WRC. The actuators 11, 12, 13 switch the sign of the angle of attack consistently 3 times per rotation of the wings 7, 8, 9, whereby all the resultant lifting force vectors are summed, integrally forming a lifting force. As is known from aerodynamics, the lifting force is proportional to the air density, wing area, the speed of circulation of the flow. For SRS, it is important to get the maximum possible lift force at the lowest possible area of the wings to reduce the number of channels of its formation. So marching speed WRC shall be not less than 600 m/s, angle of attack is close to critical, and the profile of the wings must ensure Horny vorticity of the flow, which significantly increases lifting strength.

Solve all the mentioned problems of designing WRC for re�implementation of the inventive method of flight BP known and utilized in aviation and rocket technology. A method of controlling a mode of rotation, methods of forming the SU BP is known from theory and practice of designing VSWR, TP sensor and the formation of the proposed reference signal is known, and sources indicated in the text and list of references. Thus, the solution of the inventive method of flight BP meets the criterion of industrial applicability. The novelty of the solution and its non-obviousness shown above. The expected technical result: increase range range BP for hitting distant targets of the enemy and the expansion of application fields of BP.

FIELD: aeronautical engineering; control systems of unmanned flying vehicles provided with target coordinator and passive homing system.

SUBSTANCE: proposed method consists in selection of tracking point inside target loop and measurement of parameters of motion of flying vehicle relative to this point. During autonomous flight of flying vehicle, its selective guidance is ensured by forming limited tracking zone around selected tracking point with many threshold magnitudes and respective time intervals. When tracking point gets beyond these thresholds, its position is restored by forced correction. In case tracking within this zone is unstable after several correction cycles, guidance in target loop is performed instead of selective guidance by making several correction cycles of tracking point. In case tracking is unstable again, target is considered to be lost. Homing is replaced by forced motion of flying vehicle in way of reference tracking point over rectilinear trajectory and fixing the axis of target coordinator in direction towards selected tracking point. Attempts are made for locking-on new tracking point inside target loop. In case of successful attempt, homing of flying vehicle to new tracking point is performed. In case of unstable tracking, target lock-on is considered to absent and fixed position of target coordinator axis is restored positively. As target range reduces, approximate linear deviation of tracking point is maintained constant inside target loop.

EFFECT: enhanced efficiency of flying vehicle due to selective guidance and retaining controllability in case of loss of target.

FIELD: armament, in particularly, rocketry, applicable in development of missile-weapon complexes with beam-rider guidance systems, in which the missile flight trajectory, for example, close to and parallel with the ground surface, or water surface.

SUBSTANCE: from the moment of start a program-changed pitch command is formed on the missile, and at an entry of the missile in the beam area control is effected by the TV guidance system. In the horizontal plane the directions of the missile start line and beam are matched with the zero value of command messages. In the vertical plane the direction of the missile start line is adjusted in angle above the beam direction with the zero values of the command messages, and the beam-rider guidance system is controlled by the guidance system from the moment of getting of the missile to the beam area with zero values of command messages in the vertical plane, the missile is twisted in bank angle. Described are two modifications of the complex of the missile telecontrolled in beam. The first modification has a missile that includes components of missile electromechanical joining, autopilot, and a series-connected receiver and a coordinate separation unit, as well as a control station that includes a sight-guidance instrument and a start control device, which is connected via the device of the electromechanical joining of the launcher to the components of the missile electromechanical joining, the receiver is coupled by electromagnetic radiation to the sight-guidance instrument; installed on the missile are a delay unit and series-connected starting pulse shaper, variable command shaper and an adder, the heading and pitch outputs of the coordinates separation unit are connected, respectively, to the first and second inputs of the delay unit, the heading output of the delay unit is connected to the first input of the autopilot, the pitch output of the delay unit is connected to the second input of the adder, the adder output is connected to the second input of the autopilot, and the third input of the delay unit is connected to the output of the starting pulse shape, whose input is connected to the components of the missile electromechanical joining. The second modification differs from the first one by the fact, that the receiver output is connected to the first input of the delay unit, whose output is connected to the input of the coordinates separation unit, the pitch output of the coordinates separation unit is connected to the output of the starting pulse shaper, whose input is connected to the components of the missile electromechanical joining.

FIELD: armament, in particular, rocketry spinning in bank angle, applicable in missile guidance systems, in which beam-rider guidance systems are used, for example.

SUBSTANCE: the electromagnetic radiation from the control station is converted on the missile into the components of the command signal, corrected and a command signal is formed from the corrected values. A bank signal is generated on the missile in the form of electric pulses, whose durations are formed to be equal in value to angular intervals, formed at missile bank spinning, the duration of each pulse is transformed into a binary number, whose value corrects the values of the components of the command signal. Introduction in the missile guidance system of a connected-in-series roll-angle pick-off and a "duration-code" converter has enhanced the reliability due to the use of the missile of roll rate for correction of the value of the command signal on the missile.

EFFECT: enhanced reliability due to the use of the missile roll rate as a regulating value, that corrects the command signal on the rolling missile.
