In the process of the optimum design of aprons, solutions should be found for problems and such issues as the optimum area and dimensions of the apron, including the passenger and the cargo the number and dimensions of the gates on the basis of different types of aircraft parking configuration aircraft simulation and arrangement in different time periods of the given day at the airport. In this...

A method for accurately measuring the drag associated with a protuberance on an aircraft has been devised and implemented in a wind tunnel using a C-130 model. The C-130 aircraft has been heavily modified for various different configurations and the impact that these modifications have had on the aerodynamic performance of the aircraft has not been well documented. This paper describes a method...

Unsteady flow computations are presented for a Gulfstream aircraft model in landing configuration, i.e., flap deflected 39° and main landing gear deployed. The simulations employ the lattice Boltzmann solver PowerFLOW to simultaneously capture the flow physics and acoustics in the near field. Sound propagation to the far field is obtained using a Ffowcs Williams and Hawkings acoustic analogy ap...

Advancements in computer hardware in recent years have made it possible to solve complex real world problems using finite element methods (FEM). Full scale dynamic certification testing of aircraft seats is a very complex, expensive and time consuming process. A high acceleration pulse is applied on the seat structure in a short duration of period, and the seat structure has to pass stringent F...

We address a dynamic repair shop scheduling problem in the context of military aircraft fleet management where the goal is to maintain a full complement of aircraft over the longterm. A number of flights, each with a requirement for a specific number and type of aircraft, are already scheduled over a long horizon. We need to assign aircraft to flights and schedule repair activities while consid...

This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...

CONTEXT Installation of automated external defibrillators (AEDs) on passenger aircraft has been shown to improve survival of cardiac arrest in that setting, but the cost-effectiveness of such measures has not been proven. OBJECTIVE To examine the costs and effectiveness of several different options for AED deployment in the US commercial air transportation system. DESIGN, SETTING, AND SUBJE...

In this paper the problem of detecting and isolating faults on the actuators of a small commercial aircraft using online approximators is dealt with. In particular the capabilities of radial basis neural networks to approximate faults on the engines and elevators of an AP-68 Vulcanair commercial aircraft are investigated also in the presence of model uncertainties and external disturbances. The...
