Inner shaft is then embedded in one group of coil windings on corresponding position, and when duck rudder and the relative rotation of body inner shaft, coil windings can be generated
Induced electromotive force, working principle is identical as permanent magnet generator, therefore the two constitutes outer rotor permanent magnet generator.
A kind of projectile correction executive device on bispin shell of the utility model, concrete operating principle is:
Have on duck rudder outer housing there are four the rudder piece connected firmly in " ten " word, duck rudder is fixed on body outer housing, such as Fig. 3 institute
Show, wherein No. 1 rudder piece and No. 3 rudder pieces are known as rudder in the same direction, when trajectory needs to correct, provides corresponding correcting force for bullet;No. 2
Rudder piece and No. 4 rudder pieces are known as Jenkel rudder, for providing the pneumatic rolling moment of duck rudder rotation.After pellet injection, body high speed is revolved
Turn, duck rudder reversely rotates under the action of Jenkel rudder with body.When the stable rotation of duck rudder, the steering force pair of rudder generation in the same direction
The mean effort of body is zero, and trajectory does not change.When revolving speed is zero to duck rudder relative to the earth, rudder in the same direction will generate body
Correcting action power, trajectory will change, and realize projectile correction.
As shown in figure 4, shell is rotated the angular moment M to be formed in flight course by the rudder wingxWith bearing frictional torque Mf
Collective effect will receive electromagnetic torque M in amendmenteEffect.Since there is angular velocity of rotations for correction mechanism, so will
By pole damping torque MxdEffect, its direction is with correction mechanism angular speed on the contrary, size is directly proportional to revolving speed.
Shell goes out body high speed rotation after bore, and since angular moment acts on, duck rudder is reversed with certain revolving speed and body
Rotation.Responsiveness is corrected to improve, to complete to subtract rotation to steering engine before the amendment stage.The process need to meet the condition of formula (1).
Mx+Mxd> Me+Mf (1)

Mx+Mxd=Me+Mf (2)
In the projectile correction stage, duck rudder revolving speed is relatively low, pole damping force very little thus it is negligible, duck rudder is mainly led
Torque, bearing frictional torque and electromagnetic torque.When amendment bullet needs to correct, passes through and control electromagnetic torque MeSize control
System amendment rudder piece is fixed to stop at a certain specific angle correction, which needs to meet (3) formula condition.
Me> Mx-Mf (3)
The process electromagnetic torque will constantly reduce from the larger value, until keeping steering engine static relative to the earth.At this time:
Me=Mx-Mf (4)
A kind of projectile correction executive device on bispin shell of the utility model, the course of work are as follows:
Step 1, in shell flight course, controller obtains guidance system and provides the position angle that amendment rudder piece needs to hover
θ1。
Step 2, practical duck rudder rolling speed omega is measured using the spatial motion sensor inside duck rudder2With amendment rudder piece position
Set angle, θ2, obtain with angu-lar deviation θ, according to the theorem of kinetic energy of rotary system:
Acquire resultant moment M:
Wherein θ=θ2-θ1, J: update the system rotary inertia.
When known to resultant moment, since angular moment and bearing friction power can be calculated, electromagnetic torque can be obtained according to (4) formula
Me, due to,
Me=CTΦIa (7)
Wherein CTFor the torque constant of magneto, Φ is every grade of magnetic flux (Wb).When known to the parameter of electric machine, CT, Φ not
Become, so MeWith IaIt is linear relationship.
Step 3, microprocessor controller is by acquiring armature supply IaSize, output control voltage, pass through control constant current
Electronic load in control circuit, size of current needed for controlling magneto.
Step 4, feedback duck rudder motion information is constantly updated finally by sensor, controller constantly updates control voltage,
Until duck rudder stops relative to the earth, to realize projectile correction, control process is as shown in Figure 5.
A kind of projectile correction executive device on bispin shell of the utility model corrects component by fixed duck rudder,
Come the advantages of controlling steering engine revolving speed, be capable of providing biggish stabilizing moment, realize the amendment of two-dimensional space, meanwhile, correcting device
