Determining The Economic Plausibility Of Dual Manifesting Reusable Launch Vehicles And Reusable Orbital Transfer Vehicles For The Replenishment Of Military Satellites, Crystal L. Evans

Theses and Dissertations

Currently, the Air Force launches military satellites on expendable launch vehicles to low earth orbit (LEO), and with the use of a chemical upper stage or an apogee kick motor, moves the satellite to a higher orbit. This launch procedure is extremely costly because it requires additional launch preparations, technology considerations, equipment, and fuel. Also, the additional mass of the chemical upper stage causes a larger, and thus more expensive, launch vehicle to be required. An economical alternative is to utilize reusable launch vehicles (RLVs) and reusable orbital launch vehicles (ROTVs). This concept could possibly achieve even greater savings if …

Analysis Of Aircraft Sortie Generation With Concurrent Maintenance And General Service Times, Daniel V. Hackman

Theses and Dissertations

The primary objective of this study was to develop an analytical methodology for evaluating an aircraft sortie generation process. The process is modeled as a closed network of general service queues with a fork join node to model concurrent servicing. The model uses the Mean Value Analysis (MVA) algorithm and general queueing network analysis by decomposition to approximate network performance measures including resource utilization and the overall sortie generation rate. The results of the study show that the analytical approximation's accuracy decreases as server utilization increases. However, when server utilization is kept in realistic ranges, the approximation is very accurate. …
