Abstract
A gas turbine engine has a circumferential staging configuration of fuel injectors in a combustor. As a turbine blade revolves within the gas turbine engine it is subjected to lift and drag forces based on the configuration of lit injectors. A configuration of lit injectors that results in the minimum unsteady forces the turbine blade experiences is determined in order to increase the life span of the turbine blade and limit any structural failures.
