Abstract
Dynamics of aircraft landing gears with and without pre-rotation has been analysed. The ground friction work is been formulated which raises the temperature of touch point to the rubber smoke point. The sliding time, distance, power and energy released by the friction at touch point have been presented. Simulation of target speed has been shown for different levels of pre-rotation torque.

Summary
Up to date, during the touchdown, all aircraft generate smoke, blacken the runway and cause significant tyre wear. No doubt, this behaviour of landing applies damage to environment and increases costs on aircraft operation. Fundamental understanding to the touchdown problem and the measure to reduce the landing smoke are seriously lacking. The authors have proposed some fundamental approach to analyse and simulate the dynamic behaviours [11,12] for aircraft touchdown processes. This paper is reflecting the novel but approach to the problem by the author, aiming for eventually getting rid of the landing smoke, increasing the tyre life cycle and protecting the environment
