The Architectural Assessment Tool - enhanced (AATe).
The AATe is an MS Excel based application with a relatively simple graphic user interface for a cost or operations analyst to define the design of each stage of a reusable launch system. The AATe works ideally for reusable booster definition at a conceptual level. Results are best used relatively, such as relative to Shuttle or relative to other concepts assessed with the tool. However, absolute values may be used as rough-order-of-magnitude (ROM) estimates in the cost analysis of recurring ground systems effort.
The AATe requires at least 29 inputs per element (an element is usually akin to a stage, but with some more flexibility in definition). For increased fidelity 62 inputs can be defined. Example Input Types are:
In using any model to contribute significantly or even partially to an important decision, users should be aware of the limitations of the model. Users should be aware that the AATe:
