A Method to Describe the Process of Shaping Operational Effectiveness of Military Aircraft – An Outline

Abstract The paper deals with the process of shaping the operational effectiveness of military aircraft under some specific circumstances, i.e. while flying on missions. The term ‘effectiveness’ has been assumed to mean the probability of accomplishing an air mission by one of the aeronautical system’s components, i.e. the aircraft together with its pilot. There is a chance to improve the effectiveness, or make it worse, in subsequent flights, depending on how the maintenance support function. The correct operation and maintenance of the system’s components should provide that the following condition is satisfied: * Pk ≥ P , where Pk - effectiveness in the k-th flight, and P* - the lower demanded limit of effectiveness. The Authors drew their inspiration for this paper from publication [2].

Cathodic Protection System

Cathodic protection is a very well-known method of preventing or stopping reinforcement corrosion and thereby extending the service life of reinforced concrete civil structures. However, a number of factors, which among others are design, materials and components, installation methods, quality of workmanship, and operation and maintenance of the cathodic protection system, have influence on the functionality and effectivity of the cathodic protection system. The optimum design that fulfils the Client''s requirements to cost, traffic disruption, service life, etc. shall be determined in accordance with the structure layout and the ability of the Client''s organisation to conduct operation and maintenance. It is critical to ensure that all components are installed properly to achieve the expected service life of the system. Regular and correct operation and maintenance is also crucial to ensure the functionality and effectivity system.

Economic Developments

Abstract International political and socio-economic developments have led the armed forces of many countries to become more aware of how their increasingly-stringent financial budgets are spent. One major expenditure for military authorities is upon aero-engines, because in-service deterioration in any mechanical device, such as an aircraft's gas-turbine engine, is inevitable. Each deterioration has an adverse effect on the performance and shortens the reliable operational life of the engine, thereby resulting in higher life-cycle costs. For a military aircraft's mission-profiles, the consequences of an aero-engine's deterioration upon the aircraft's operational-effectiveness as well as its fuel consumption and life have been predicted in this project using validated computer-simulations. These help in making wiser management-decisions, so leading to the achievement of improved engine utilisation, lower overall life-cycle costs and optimal mission effectiveness for squadrons of aircraft.
