Maintainability methodology and maintenance analyses

Initial approach in performing maintainability studies involves detailed description of methodology used. Maintenance analyses are formulated for system, subsystem, and component levels. These are performed to ensure that complete, integrated, logistics system support elements are identified.

Reusable Aerospace Passenger Transport - Study of Incremental Development Approaches Summary Report

This report summarizes the results of studies of economical orbital transportation systems, exploring, in particular , possible options for time - phases and incremental development of such systems. The major conclusions are : 1. Incremental development is a practical way for development of an economic logistics system, minimizing development risk and annual funding, and offering planning flexibility at only a nominal penalty in total systems cost. 2. The most promising first development appears to be that of a re- usable payload carrier with a capacity of 9 to 12 passengers. 3. Systems comparisons show that, for the foreseeable variations of the mission market, a partially reusable concept could bring about most of the program savings that can be expected from reusability at moderate development risk and funding rate. 4. A further development leading to a fully reusable system has high risk and uncertain payoff. Conceivably, at that time, a more advanced concept might be introduced.
