INTRODUCTION Neck pain in fighter pilots has been studied by several air forces and found to be relatively common. The aim of this project was to study the incidence, characteristics, possible associated causative factors, and operational impact of neck pain in Royal Norwegian Air Force (RNoAF) fighter pilots. METHODS The study was designed as a retrospective anonymous questionnaire survey, c...

Sensors, weapons and systems are some of the key determinants of success in counter-air warfare. This paper explores the growth potential in many of the basic technologies used to implement sensors, weapons and systems in the coming generation of fighters. Conclusions are drawn about potential performance and capability growth resulting from improvements in basic technology in the coming two de...

Flight recorders, often called “black box” are two devices designed to record data about flights. Flight Data Recorders (FDR) record various flight parameters. All aircraft’s are required to have Flight Data Recorder (Black) systems installed in it. Depending on aircraft, manufacturer can either use Non-Ejectable Flight Data Recorder or Ejectable Flight Data Recorder. This requirement is implem...

Some pilots flying modern high-performance fighter aircraft develop "hypoxia-like" incidents characterized by short periods of confusion and cognitive impairment. The problem is serious and recently led to the grounding of a fleet of aircraft. Extensive discussions of the incidents have taken place but some people believe that there is inadequate data to determine the cause. There is a tremendo...

A flight test evaluation of the performance-seeking control (PSC) algorithm on the NASA F-15 highly integrated digital electronic control research aircraft was conducted for single-engine operation at subsonic and supersonic speeds. The model-based PSC system was developed with three optimization modes: minimum fuel flow at constant thrust, minimum turbine temperature at constant thrust, and ma...

The Air Operations Division (AOD) of the Defence Science and Technology Organisation (DSTO) has developed a range of simulation tools for Air Combat modelling. Two of these, the Air Operations Simulation Centre (AOSC) (which provides a facility for Human-in-the-Loop (HiL) simulation), and the BattleModel (which provides intelligent Computer Generated Forces (CGFs)), are currently being integrat...

Aircraft dynamics are in general nonlinear, time varying, and uncertain. A control system (classical control systems) designed for a flight condition, may not provide the desired stability and performance characteristics in case of deviation from the equilibrium point. There are numerous studies regarding flight control in the literature. One of them is fuzzy flight control system. Fuzzy logic ...

This paper brings out the design of a fault-tolerant power supply unit for aircraft-store interface. switched mode provides multiple 30 V regulated and isolated DC outputs required pre-launch preparations auto-launch operations avionic sub-systems in store. 3Ø-115V-400Hz-AC as well 27V-DC are available from fighter aircraft powering up any Power (wattage) output 27V/10A is inadequate to various...

A detection scheme based on the artificial immune system (AIS) paradigm was developed for specific classes of aircraft jet engine failures including throttle, burner fuel flow valve, variable nozzle area actuator, variable mixer area actuator, low-pressure spool speed sensor, low-pressure turbine exit static pressure sensor, and mixer pressure ratio sensor. The Modular Aero-Propulsion System Si...
