Investigation of the Heat and wear of Aircraft Landing Gear Tyres

In this book, the novelty is the following: 1. The aircraft wheel behaviour is covered in one simulation, which means that the tyre heat and wear build up, instead of every condition being simulated separately. 2. The aircraft landing simulations include the horizontal and vertical landing speeds. The vertical velocity of the aircraft body is considered by pointing the landing gear, with a space between the wheel and runway at the beginning of the simulation. The wheel is connected with a shock absorber and there is a weight box. This is useful to find the tyre impact, deflection, spin-up, and free rolling, which will give changeable reaction and friction forces versus time, as the friction force is the main factor in tyre heat and wear. 3. The effect of pre-spinning the wheel on the tyre heat and wear is investigated. 4. The tyre wear is calculated with respect to the variable rubber hardness according to the tyre tread temperature for more accuracy. Moreover, different types of wind turbine have been connected to the aircraft wheel and simulated against a high wind speed. This is to check the ability of wind turbines to spin aircraft wheels at approach.
