ARIES
Aircraft Rollout Iterative Energy Simulation
The ARIES program analyzes aircraft brake performance during rollout. The program simulates a three degree of freedom rollout after nose gear touchdown. The amount of brake energy dissipated during landing determines the life expectancy of brake pads. ARIES incorporates brake pressure, actual flight data, crosswinds, and runway characteristics to calculate the following: 1) brake energy used during rollout for up to four independent brake systems, 2) time profiles of rollout distance, velocity, deceleration, and lateral runway position, and 3) all aerodynamic moments on the vehicle. ARIES can be adapted for modelling most landing aircraft during unpowered rollout. Optimum braking procedures can be developed with ARIES to minimize brake deterioration while staying within specified lengths of runway. ARIES has been used to evaluate several Shuttle Orbiter brake pad failures.
