Jet noise reduction remains an important long-range goal in commercial and military aviation. Comparedwith their early counterparts, modern, ultrahigh-bypass-ratio turbofans on commercial aircraft are very quiet, but evermore stringent noise regulations dictate further reductions. In addition, hearing loss bypersonnel and community noise issues are prompting the military to seek noise reduction...

Introduction Supplier development and management systems of U.S. aircraft manufacturers have evolved rapidly during the 1990s in an environment of reduced military procurement and a worldwide slump in commercial aircraft sales. The result has been an ongoing restructuring within the aircraft industry supplier base, with significant implications for customer-supplier relationships and, potential...

Military physicians have long recognized that rapid evacuation from the battlefield decreases suffering and prevents death. Air medical evacuation (MEDEVAC) of seriously ill and injured patients during military operations was pioneered in the United States by the US Army. The first use of an aircraft to evacuate US Soldiers was in 1926 when the US Army Air Corps transported them from Nicaragua ...

We evaluated 10 years of reported hazardous cargo incident information from the U.S. Air Force and Naval Safety Centers. In this first of two papers describing the hazardous cargo problems reported by the two services, we describe types of aircraft and types of hazardous cargo involved in incidents not causing aircraft mishaps. Normally, hazardous cargo must be manifested as such and no passeng...

Visual detection of aircraft by human observers is an important element of aviation safety. To assess and ensure safety, it would be useful to be able to be able to predict the visibility, to a human observer, of an aircraft of specified size, shape, distance, and coloration. Examples include assuring safe separation among aircraft and between aircraft and unmanned vehicles, design of airport c...

Abstract FA-50 aircraft is a combat version of the KAI T-50 Golden Eagle jet trainer. The development began in October 1997.The phase finished January 2006, during which 6 prototypes were built. It worth noting that 2012, was awarded military certificate issued by Korean MAAC (Military Aircraft Airworthiness Committee) as first fighter-class aircraft. On 16 September 2022, approval ceremony for...

We study a dynamic repair shop scheduling problem in the context of military aircraft fleet management. A number of flights, each with a requirement for a specific number and type of aircraft, are already scheduled over a long horizon. The overall scheduling horizon is considered to be composed of multiple time periods. The goal is to maintain a full complement of aircraft. We need to assign ai...
