Abstract: Combustion systems for a gas turbine engines are provided. The combustion system is configured to provide a fuel-air mist to achieve light-off during high altitude start (e.g., at altitudes greater than 45,000 ft.) without flame out. The combustion system may also be configured to provide additional air to the combustion chamber at high altitude to facilitate flame propagation and second stage burn.
