Trajectory Correction Projectile Canard Correct Methods Of Study

Present-day, higher precision and lower price of guided ammunition are very important for wars, trajectory corrected guided projectile is such a guided ammunition. Its postulate is adding control system to common cannonball and correcting its trajectory. One of the controlling methods is using canard wings. The paper is just researching canard wing-controlling method.In the dissertation, canard wing' s characteristic and strongpoint were discussed. Predigesting mechanics model was built according to the rules of canard wing; An uncontrolled trajectory model and an controlled trajectory model was built aim at 1.00mm mortar bomb; The models were calculated to get the result of range and landscape orientation correcting; At last, an idea about how to optimize controlling parameters was discussed.In the dissertation, such a conclusion was gained: Canard wings can correct not only one-dimension trajectory but also two-dimension by changing the controlling power. The effects are good.
