METHOD FOR MONITORING OF ACCURACY OF ADJUSTMENT OF FLIGHT VEHICLE SIGHT IN HORIZONTAL PLANE Russian patent published in 2002 - IPC

FIELD: tests and checks of sighting and aiming aids of flight vehicle. SUBSTANCE: referencing of the fixed coordinate system of the flight vehicle to the target placed in front of it is carried out in flight in the "Visual correction" conditions. After stabilization of the flight vehicle attitude by the automatic control system without changing the position of its flying controls, the sight movable marker is matched with the target with the use of the reticule control mechanism. The error of adjustment is determined as mismatch Δϕ_г between the reticule indicating the required position of the zero of the sight fixed axis on the target and the true position of the sight fixed axis with the use of the analytical dependence: , where D₀ - range to target at the instant of execution of visual correction of the flight vehicle coordinates; D - range to target; Δϕ_г - error of adjustment; f_г - target sighting angle. EFFECT: improved monitoring of accuracy of adjustment of the flight vehicle sight in the horizontal plane.
