A mixed-integer nonlinear optimization model is presented for the resolution of aircraft conflict. Aircraft conflicts occur when aircraft sharing the same airspace are “too close” to each other and represent a crucial problem in Air Traffic Management. We describe the model and show some numerical experiments.

The Aerosonde is a small robotic aircraft designed to undertake a wide range of operations in a highly flexible and inexpensive mode. Holland et al. (1992) laid out the conceptual basis of an Aerosonde operation that would enable meteorological observations in remote and otherwise inaccessible regions. A prototype aircraft was first flown in 1993, demonstrating the viability of the platform and...

This paper proposes novel Fuel Cell Auxiliary Power Unit (FCAPU) for J150+ aircraft application. The primary version of APU in J150+ aircraft is a gas turbine Auxiliary Power Unit (APU) which is based on gas turbine jet engine but in the suggested FCAPU, the generated electrical power is achieved from chemical energy with higher efficiency. The Solid Oxide Fuel Cell (SOFC) technology is used to...

Thrust vector control (TVC) might be used to aircraft at large altitudes and in post-stall conditions when aerodynamic surfaces are ineffective. This study demonstrated that the implementation of TVC on high-speed is a reasonable solution an alternative compared complicated reaction system or surfaces. The numerical flight dynamics model X-15 experimental was developed implemented MATLAB/Simuli...

Anewparadigm for building anEulerian–Lagrangian cell transmissionmodel for air trafficflow is developed. It is based on an aggregation of track data and is applied to the full National Airspace System in the United States. The Eulerian–Lagrangian model is based on a multicommodity network flow model constructed from historical air traffic data. The flow model is reduced to a linear time invaria...

This paper presents hybrid integration between aerodynamic, airline procedures and other BADA-based (Base of Aircraft Data) coefficients with a classical aircraft dynamic model. This paper also describes a three-dimensional guidance algorithm implemented in order to produce commands for the aircraft to follow a flight plan. The software chosen for this work is MATLAB. Key words— UAS, aircraft, ...

The development of electromechanical actuators (EMAs) is the key technology to build an all-electric aircraft. One of the greatest hurdles to replacing all hydraulic actuators on an aircraft with EMAs is the acquisition, transport and rejection of waste heat generated within the EMAs. The absence of hydraulic fluids removes an attractive and effective means of acquiring and transporting the hea...

Airbus Industrie is considering building a family of double-deck aircraft. A research project was initiated primarily to investigate the effects of the height of the new upper deck on human performance in case of an emergency, but it was also investigated whether factors such as visibility, slide design, and passenger safety instruction might influence individuals‘ performance. A performance mo...

This paper details the design and development of the Airborne Subscale Transport Aircraft Research (AirSTAR) test-bed at NASA Langley Research Center (LaRC). The aircraft is a 5.5% dynamically scaled, remotely piloted, twin-turbine, swept wing, Generic Transport Model (GTM) which will be used to provide an experimental flight test capability for research experiments pertaining to dynamics model...
