The origins of the Design-to-Cost concept and the ap-
plication of parametric cost estimating models for fixed
wing aircraft are revealed in an extensive dicussion of the
literature search. It was discovered that a void exists in
the literature concerning advances in cost estimation tech-
niques for the helicopter industry.
The purpose of this research was to develop parametric
Design-to-Cost models for selected major subsystems of cer-
tain helicopters. This was accomplished by analyzing the
relationships between historical production costs and cer-
tain design parameters which are available during the pre-
liminary design phase of the life cycle.
In conjunction with the problem, four subproblems were
identified as follows:
1. Determination of major helicopter subsystems to be
analyzed
2. Selection of techniques to be used in normalizing
the historical cost data
3. Identification of design parameters which are
available during the preliminary design phase
4. Derivation of the parametric Design-to-Cost equa-
tions
