During an aircraft landing with activated thrust reversers, which mechanism extends engine life?

💡 Explanation

Turbine blade temperature reduction extends engine life during landings because reverse thrust introduces cooler external air into the engine using the cold stream thrust reverser, therefore alleviating thermal stress, rather than improving nacelle aerodynamics, shock absorption or airframe buffeting.
