  • Owing to the deck motion and some other factors, the aircraft often has off-center distance with the catapult orbit. To study with this phenomenon, considering the deck motion, landing gear cushion and flexible tires, a six-degree-of-freedom mathematic model of carrier-based aircraft off-center catapult launch was established. The aircraft attitude during catapult taxing affected by the off-center distance with typical deck motion was studied. From the off-center catapult launch calculation, three important conclusions were obtained.The yaw movement are affected clearly by the initial off-center distance and its amplitude increases with the increase of the initial off-center distance.The attenuation of the yaw movement is clearly during catapult taxing and the launch bar side bending moment increases with the increase of the initial off-center distance. The results provide theoretical foundation for carrier-based aircraft design.
