Abstract:
1. A method of producing a plurality of effusion holes in a wall of a combustor of a gas turbine engine, the method comprising the steps of: a) determining a hole pattern definition using: a count of the holes to be separated by first spaces in a row of holes along a first axis, positional information of a first hole in the row of holes, a first length of the row of holes, and, a first spacing ratio relating hole spacing distances between each adjacent hole within the row of holes, and further comprising determining the hole pattern definition using the geometric relation b) using the hole pattern definition to identify individual positions of the effusion holes to be produced in the wall of the combustor; and c) using a hole producing system to produce the effusion holes in the wall of the combustor at the identified positions.
