The airline industry has been changed significantly after the September 11 of 2001, while delay and congestion at airport have been consistently a problem to passengers, airlines and airports since the last decade of the 20 century. Most of previous methods to reduce airport delay and congestion mainly focus on airport capacity expansion through building new runways, which incurs billions of do...

This paper is centered on using chemical reaction as a computational metaphor for simultaneously solving problems. An artificial chemical reactor that can simultaneously solve instances of three unrelated problems was created. The reactor is a distributed stochastic algorithm that simulates a chemical universe wherein the molecular species are being represented either by a human genomic contig ...

Flight training accidents constitute 14% of general aviation accidents. Herein we determined the rates, injury severity, and phase of flight for primary student solo accidents/incidents (mishaps) in Cessna 172 aircraft. Mishaps over the period spanning 1994–2013 were identified from the NTSB database. Student population data were from the FAA. Statistics employed proportion tests, Poisson distr...

Heavy aircraft main landing gear tyres skid immediately after touchdown as result of the high slip ratio between the tyres and runway, which lead to tyre wear and smoke. In this paper, the tyre wear is modelled on the Archard theory using ANSYS mechanical transient, to reveal the wheel’s dynamic and the tyre tread wear. The wheel’s dynamic and the amount of wear are calculated for initially sta...

The forward looking radar imaging task is a practical and challenging problem for adverse weather aircraft landing industry. Deconvolution method can realize the forward looking imaging but it often leads to the noise amplification in the radar image. In this paper, a forward looking radar imaging based on deconvolution method is presented for adverse weather aircraft landing. We first present ...

An air/ground simulation of TrajectoryOriented Operations with Limited Delegation (TOOWiLD) was conducted at NASA Ames Research Center in September 2006. Four radarcertified air traffic control (ATC) specialists in the Airspace Operations Laboratory (AOL), eight glass cockpit pilots in the Flight Deck Display Research Laboratory (FDDRL), and additional “ghost” pilots and controllers operated a ...

This paper describes an analytic real-time emergency landing trajectory planner applicable in situations where an aircraft experiences severe damage or failure(s) that contract the feasible lateral plane flight envelope. Solutions are constructed as sequences of spirals that follow a reference arc, extending a traditional Dubins path solver to handle cases in which an aircraft cannot fly straig...

This paper focuses on the aircraft landing optimization problem where both the landing routes and the landing order of aircrafts should be optimized to minimize an occupancy time of airport, and proposes its optimization method which is robust to dynamical situations such as weather condition change and other aircrafts’ landing routes change. As a difficulty of this optimization problem, approp...

The NASA goal of reducing external aircraft noise by 10 dB in the near-term presents the acoustics community with an enormous challenge. This report identifies technologies with the greatest potential to reduce airframe noise. Acoustic and aerodynamic effects will be discussed, along with the likelihood of industry accepting and implementing the different technologies. We investigate the lower ...
