The Department of Defense (DoD) spends about $15 billion annually on depot level maintenance. About 60 percent of this funding is provided to government owned and operated depots. In light of defense budget downsizing, it has become more critical than ever that depots are run in the most efficient manner possible. DoD has tried to adopt a 'best commercial practices' approach to improve efficiency of depot maintenance. A key focus of commercial practices is delivering customer satisfaction. To...

The Expert System Advisor for Aircraft Maintenance Scheduling (ESAAMS) was originally proposed to assist tin the scheduling of discrepancies in a naval aviation squadron maintenance department. This thesis addresses the development of a knowledge base for ESAAMS which will support the stated goals of the system. An overview of expert systems in general and specifically the ESAAMS system is presented as background information to the reader. A specific approach to acquiring, documenting and...

Cannibalization is a technique, sanctioned by the Navy, for maintenance managers to optimize aircraft availability by circumventing a slow or inadequate logistics support system Maintenance managers often make a decision to cannibalize without considering the total cost of their decision This thesis examines the costs incurred by an operational H-6O helicopter squadron to cannibalize major components and addresses the impact of cannibalization on the mean time between failure for the...

The Naval Aviation Maintenance Program recognizes cannibalization as a viable management tool when properly used in aviation squadrons. Squadrons consequently practice cannibalization in an attempt to reduce gaps in their logistical and maintenance support systems. This thesis analyzed cannibalizations on the MV-22 aircraft platform to examine how the practice varied between squadrons in the community, which specific components drove cannibalizations, and how the practice of cannibalization...

The paper presents a comparison of experimental noise data measured in flight on a two-engine business jet aircraft with Kulite microphones placed on the suction surface of the wing with computational results. Both a time-domain discontinuous Galerkin spectral method and a frequency-domain spectral element method are used to simulate the radiation of the dominant spinning mode from the engine and its reflection and scattering by the fuselage and the wing. Both methods are implemented in...

This thesis examines current metrics used by a Marines Aviation Logistics Squadron (MALS) and how a MALS can be measured for overall performance in regard to supporting flight-line squadrons. Currently used primary metrics are analyzed for their ability to reflect the level of support a MALS provides, the behavior that those metrics incentivize, metrics that should be adopted, and how standardized metrics can be used to compare performance between various MALS. Supply shelf items with a...

Parallel with the development of National Defense and Security (in the third of the Five- Year Development Plans), the TNI-AU (Indonesian Air Force) purchased many types of aircraft weapon systems. To maintain these new aircraft, the Indonesian Air Force faces several problems which have not been solved. This thesis studies the aircraft maintenance logistics system. The first part of the thesis analyzes the factors which cause the problems. The second part consists of proposals to standardize...

A study was made to develop a method to determine and evaluate the best aircraft maintenance system for use by the Army in the field. Its principal objective was not to solve the problem for any one specific set of conditions but to develop a procedure by which Army personnel can arrive at the best solution for any specific set of conditions.

The objectives of this project were to determine whether (1) microgravity permits unique, three-dimensional cultures of neoplastic human colon tissues and (2) this culture interaction produces novel intestinal growth and differentiation factors. The initial phase of this project tested the efficacy of simulated microgravity for the cultivation and differentiation of human colon carcinoma in rotating wall vessels (RWV's) on microcarrier beads. The RWV's simulate microgravity by randomizing the...

Aviation fleet maintenance (AFM) funds are used to maintain and support the U.S. Navy's fleet of operational aircraft. Previous studies and AFM managers (Reily and Sheppard, 1980; Naval Audit Service, 1981; Needham, 1981) have expressed the opinion that the management of these funds can and should be improved. This thesis compares the current system of accounting and control to a model of management control developed in the thesis. The thesis presents specific recommendations for improving the...

The 2016 United States Marine Corps (USMC) Aviation Plan establishes the timeline to transition all F/A-18 Hornet squadrons to the F-35 Joint Strike Fighter. Ensuring Hornets can continue to support operational requirements during this transition is a challenge. In this thesis we address the management of the USMC Hornet inventory by developing, implementing, and testing an integer linear program called Hornet Assignment Sundown Model (HASM). HASM prescribes each individual Hornet's monthly...

Rapid progress has been made in the past few years in the development of high-powered aircraft engines; however, insofar as fundamentals are concerned, they have not changed since their conception at the beginning of the twentieth century. The power developed by internal combustion engines is dependent upon the type of fuel used; therefore it necessarily follows that the future increases in power obtained from conventional aircraft engines depend upon the development of fuels.

Condition-Based Maintenance (CBM) has been the focus of Department of Defense efforts to reduce the cost of maintaining weapons systems for nearly two decades. Through an investigation of the MH-60S helicopter, this paper uses a gap analysis framework to determine the value of increasing CBM usage. The Naval Aviation Maintenance Program (NAMP) has used scheduled inspections as the backbone of aviation maintenance since 1959. The most significant of these inspections is the phase cycle, which...

In our 2010 assessment of weapon programs, we made several observations concerning DOD's management of its major defense acquisition portfolio. First, in DOD's fiscal year 2010 budget, the Secretary of Defense proposed canceling or significantly curtailing programs with projected total costs of at least $126 billion that he characterized as too costly or no longer relevant for current operations, while increasing funding for others that he assessed as higher priorities. Congress...

Generalized considerations for structural inspections needed to maintain airworthiness of older aircraft are reviewed. Recommendations are made to account for accumulated service usage by counting flights rather than flight hours, to inspect structures made of flaw-sensitive materials more frequently than those made of flaw-tolerant materials, and to inspect structures having little redundancy more frequently than those having more redundancy. Occasional destructive inspections of high-time...
