Description
Technical Field
The invention belongs to the field of missile design, and particularly relates to a pneumatic layout of a small high-mobility missile.
Background
Along with the development of national defense technology, the miniaturization of missiles is more and more emphasized, and various countries successively begin to research and develop microminiature guided munitions suitable for individual combat and the like. Meanwhile, the air defense requirements of targets such as unmanned planes, small airplanes and shells are met, and high requirements are provided for low-cost miniaturization and maneuvering performance of the missiles.
The maneuvering of the missile is mainly realized by changing the magnitude and direction of the force and moment acting on the missile. One way to achieve this is to implement direct force control by a vector engine, but this method has the disadvantages of difficult force control, large system size, and inability to operate for long periods of time. Another method is to vary the aerodynamic forces and moments acting on the missile by manipulating the deflection of the aerodynamic control surfaces. The required high maneuvering characteristics can be realized by reasonably designing the aerodynamic control surface of the missile, namely the aerodynamic layout of the missile.

The further technical scheme of the invention is as follows: the first-stage duck wing and the second-stage duck wing are both in trapezoidal or triangular flat wing structures, and chamfering processing is carried out on the outer edges of the duck wings.
The further technical scheme of the invention is as follows: the distance between the second-stage duck wing and the first-stage duck wing is 1-2 times of the span length of the first-stage duck wing.

the root chord length of the second-stage duck wing is 20mm, the tip chord length is 10mm, the half span length is 20mm, the wing surface thickness is 2mm, and the distance between the hinge and the head is 246 mm; the symmetrical center of the side surface of the wing root is provided with a connecting hole position for connecting the output shaft of the steering engine, and 2 wing surfaces are respectively connected with 2 independent steering engine output shafts; the hinge is used for controlling the output shaft of the steering engine of the second-level duck wing.
The tail wing is 70mm in root chord length, 40mm in tip chord length, 40mm in half span length and 2mm in wing surface thickness, the tail wing rear edge is flush with the bottom of the missile, and the four tail wings are fixedly connected with the surface of the missile body.
The further technical scheme of the invention is as follows: the missile head is in a spherical structure or a parabolic structure.
The further technical scheme of the invention is as follows: the tail wing is of a trapezoidal flat wing structure, and the edge of the tail wing is subjected to chamfering treatment; the four tail wings are the same as the four first-level canard wings in layout and are opposite in position.
Advantageous effects
The invention has the beneficial effects that:
1. the control efficiency of the second-level canard is higher, and the rolling control effect is good.
Under the same flight condition and rudder deflection angle, the control surface area with the same size and the roll control torque generated by the two-stage canard wing configuration are 1.98 times of the roll torque generated by the conventional canard wing layout missile. Meanwhile, in practical application, the requirement on missile roll control torque is low, and the roll control surface with small size can be independently designed by the layout scheme of the second-stage canard wing, so that the same or even better roll control effect is achieved. For example, when the second-stage canard wing for roll control is designed independently in the design, the wing area of the canard wing is only one third of that of the original single-stage canard wing missile, and meanwhile, the roll control of the missile is carried out independently by the second-stage canard wing without participation of the first-stage canard wing, so that the design of a control system is simpler and more efficient, and the precision of the control system is improved.
2. The rolling control torque generated by the second-level canard is approximately linearly changed, and the control system is simple in design.
As shown in fig. 3, under the same sliding angle, the roll control moment coefficient generated by the second-level duck rudder is relatively stable with respect to the change of the attack angle. Except the curve of the state of the side sliding angle of 20 degrees, other broken lines are basically changed linearly. Therefore, the roll control moment generated by the second-level canard in the longitudinal symmetric plane of the missile basically has a linear rule to the change of the attack angle.
3. The two-stage canard design enables the rolling channel to be decoupled from the other two channels, and the design of a control system is simplified.
As shown in fig. 4 and 5, the variation of the missile pitch moment coefficient with the sideslip angle and the attack angle is respectively in the non-rudder deflection state and the two-stage canard differential 10 ° state. As shown in fig. 6 and 7, the change of the yaw moment coefficient is associated with each change. The comparison of the two conditions shows that the differential rudder deflection of the duck rudder increases the pitch moment coefficient and the yaw moment coefficient, but does not change the basic variation trend. The roll control channel and other control channels can be decoupled, and the method has important significance for pneumatic parameter calculation of pitching and yawing channels, control design and the like.
