Abstract: Aircraft carrier will play an important role in present and future wars as they carry most important weapons and equipment in carrier. Catapult is most commonly used in aircraft for short takeoff. It increases the takeoff velocity so that it can take off at very short runway. This paper focuses on the dynamic forces acting on nose gear of carrier based aircraft during takeoff. This paper uses ADAMS/Aircraft as simulation software which simulates the whole dynamic forces acting on nose landing gear and main gears of the aircraft. Using ADAMS software can be a very intuitive process to see the aircraft take-off posture, all kinds of real-time data after the end of the simulation through the chart data files or output to the user. Conclusively, the result from ADAMS depicted there are very slight effect on roll and yaw, while lateral axis faces slight bump due to overshoot of CG.
