This test case is based on the Rotorcraft Turboshaft Template structure, weight distributions, and manufacturing complexities. All hardware objects are scaled to the weight of the T55. No changes are made to the software objects of the template. This example uses production schedule dates and quantities of the T55 program. No attempt has been made to differentiate among the various models of the T55 nor has any attempt been made to simulate the multiple production lots of the program. Therefore, this example should be viewed as an illustration of how the rotorcraft turboshaft template can be used to produce a rough cost estimate of a known turboshaft program.
