Landing gear is one of the critical subsystems of an aircraft. The need to design landing gear with minimum weight, minimum volume, high performance, improved life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. Further, it is essential to reduce the landing gear design and development cycle time while meeting all the regulatory and safety re...

As air traffic congestion grows, ground-holding (or "gate-holding") of aircraft is becoming increasingly common. Ground-holding is the practice of delaying the departure of a flight due to anticipated congestion at the airport of destination, because it is both less expensive and safer, for aircraft to wait on the ground, prior to take-off, than in the air. The problem of developing strategies ...

Due to the upward trend in aviation industry, existing approaches for air traffic control need be improved achieve efficient schedules. This paper deals with aircraft landing problem, which consists of determining a time each within radar range an airport and allocating it runway. We propose exact solution approach that involves mixed-integer linear programming. The objective is hereby minimize...

Airport traffic consists of aircraft performing landing, takeoff and taxi procedures. It is controlled by air traffic controller (ATC). To safely perform this task he/she uses traffic surveillance equipment and voice communication systems to issue control clearances. One of the most important indicators of this process efficiency is practical airport capacity, which refers to the number of airc...

ly, the runway scheduling problem (RSP) can be thought of as a job shop scheduling problem [11] with precedence and release time constraints, where the objective is to sequence a set of jobs (aircraft) in a particular order to be processed by a processor (runway) so that some cost function is minimized. For the runway scheduling problem, one wants to find an efficient schedule for aircraft to u...

Reducing the delays of the departing aircraft can potentially lead to improving the efficiency of the surface operations at airports. This paper addresses a departure scheduling problem with an objective to reduce total aircraft delays subject to timing and ordering constraints. The ordering constraints model the queuing area of airports where the aircraft align themselves in the form of chains...

Suppose we have an autonomous aircraft flying a complex mission broken into several different phases such as takeoff, ingress, target surveillance, egress, and landing. For each mission phase, the aircraft’s control system will have prepared a plan (or controller) specifying particular actions and reactions during the phase. Now suppose that the autonomous control system onboard this aircraft i...

This paper describes an approach to the problem of optimal motion planning with uncertain dynamics. This problem can occur whenever a vehicle suffers damage or when the environment makes the effect of motion actions unpredictable and potentially risky. We address in particular the case of aircraft with structural and/or control surface damage. The goal in this problem is to find an optimal plan...

this research, for the first time presents the flexible flow shop model of scheduling method for considering runway assignment and operations planning together. one of the advantages of the developed model is considering the procedures of air routes in terminal airspace and separation between consecutive aircraft which is very similar to the real world condition. there are different objective f...
