As rockets and jets on military aircraft become more powerful, the noise they produce can lead to structural fatigue, hearing damage, and community disturbances. Noise-reduction technologies and sound radiation prediction require accurate characterization of the noise sources within rocket plumes and jets. Near-field acoustical holography techniques were used to visualize the sound field in the...

The high noise levels being experienced in some military fast jet aircraft and helicopters generally result in a reduction in the intelligibility of speech communications. A study has been conducted to assess the effect of reducing noise levels at the ear, by the use of current Active Noise Reduction (ANR) systems, on speech intelligibility in aircraft noise environments. The results of this st...

Serum levels of cortisol and testosterone were measured in 39 United States Air Force personnel on active duty flying status. The subjects selected belonged to one of the following categories: pilot of a fighter-type aircraft, nonpilot on a fighter plane, pilot of a cargo-type aircraft, or nonpilot on a cargo plane. Blood samples were taken prior to and after a routine flying mission. Cortisol ...

The speed and altitude at which modern military aircraft operate are such that escape can only be achieved by some means of forcibly propelling the aircrew clear of the aircraft. The most common method of doing this is by use of an ejection seat. The use of such seats, whilst generally life saving, exposes aircrew to forces that may be at the limits of human tolerance. Each phase of the ejectio...

Adaptive control has the potential to improve performance and reliability in aircraft systems. Implementation of adaptive control on commercial and military aircraft requires verification and validation of the control system’s robustness to modeling error, uncertainty, and time delay. Currently, there is a lack of tools available to rigorously analyze the robustness of adaptive controllers due ...

We introduce a time-indexed mixed-integer linear programming model for a military aircraft mission planning problem, where a fleet of cooperating aircraft should attack a number of ground targets so that the total expected effect is maximized. The model is a rich vehicle routing problem and the direct application of a general solver is practical only for scenarios of very moderate sizes. We pro...

Aircraft Interception is an action in which aircraft moves towards another effort to intercept entering national airspace without a flight plan, and experiencing communication failure or cannot be identified. actions are allowed order protect the sovereign territory of country, as stated Article 1 1944 Chicago Convention recognizes that every state has complete sovereignty. However, purpose int...

Since the onset of the wars in Iraq and Afghanistan attention has increased on the importance of mental health with military service members. An integral component, although far less studied, are the ties between mental health and military spouses. Military deployments place considerable stress on military families. This study analyzed the mental health utilization of military spouses of active...

The design (or evaluation) of military aircraft, by nature, is a process consisting of conflicting goals and objectives at the conceptual, preliminary, and detailed level. Affordability, mission capability, availability (operational readiness), wartime survivability, and peacetime safety are five of the main attributes required of modern weapon systems. Traditional approaches for system evaluat...
