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 ...

The Remez penalty and smoothing algorithm (RPSALG) is a unified framework for penalty and smoothing methods for solving min-max convex semiinfinite programing problems, whose convergence was analyzed in a previous paper of three of the authors. In this paper we consider a partial implementation of RPSALG for solving ordinary convex semi-infinite programming problems. Each iteration of RPSALG in...

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...

Several experiments involving two-dimensional and axisymmetric bodies have been carried out in a Trisonic wind tunnel at supersonic speeds to investigate and analyse the measured values of base pressure and to compare them with those from the theoretical methods. The objective of the experiments was to obtain an appropriate method for processing the results of wind tunnel tests on rockets or ai...

The widespread development of unmanned aerial vehicles and light propeller-driven aircraft poses the task reducing community noise such vehicles. To solve this problem, tools are needed to calculate devices. paper presents results numerical simulation an AV-2 propeller mounted on AN-2 aircraft. authors use acoustic-vortex method problem aeroacoustic modeling in presence incoming flow. shows a g...

In real applications, it is extremely difficult (if not impossible) to define function(s) that measure the “true merit” of a design object. For example, even the most prominent aircraft designers would not dare to claim that a particular set of merit and constraint functions measures the “true merit” of a class of aircraft. The traditional approach to set up a “machine centric” optimization can...
