| 发明名称 | Determination of angle of incidence | ||
| 摘要 | The invention relates to a method for determining angle of incidence for a projectile in the path of the projectile from launcher to target, which projectile is guidable and substantially or partially roll-stable and comprises a control system and at least two actuators with associated control members, in which the following steps are included: determination of applied force for pitch control by evaluation of the moment upon the actuators of the projectile, determination of applied force for yaw control by evaluation of the moment upon the actuators of the projectile, calculation of the pitch component a of the angle of incidence and of the yaw component β of the angle of incidence, based on comparison between the evaluated moments and reference data for moments. The invention also relates to a GNC system. | ||

| 主权项 | 1. Method for determining angle of incidence for a projectile in the path of the projectile from launcher to target, which projectile is guidable and substantially or partially roll-stable and comprises a control system and at least two actuators with associated control members, which comprises the following steps: measuring a moment upon the actuators of the projectile; determination of applied force for pitch control based on the measured moment upon the actuators of the projectile, determination of applied force for yaw control based on the measured moment upon the actuators of the projectile, calculation of the pitch component α of the angle of incidence and of the yaw component β of the angle of incidence, based on comparison between the evaluated moments and reference data for moments. | ||
