Rapid Transfer Alignment Simulation for Missile Onboard Helicopter
In order to improve transfer alignment precision and speed of missile onboard helicopter, the errors arising out of the time delayed of data transmission from master to slave INS and lever arm have been considered and compensated. With deduced the differential equations which including time delay variable and adopted an advanced velocity+attitude information matching method, A Kalman filter model of transfer alignment scheme has been built. Aim to satisfy the requirement of helicopter and weapon system, the paper puts forward a new maneuver manner for helicopter to transfer alignment, The simulation results show that the performance of the transfer alignment is great improved due to the compensation. Within 10 seconds, the three misalignment angles error is less than 3. Alignment speed and precision satisfy the combat requirement of missile onboard helicopter. Compared with traditional method, the maneuver manner presented by the paper has some advantages, such as simplification, easily realization and fit for helicopter.
