A decentralized control algorithm for the construction of a tetrahedral configuration using differential lift and drag forces is proposed in this paper. Four 3U CubeSats launched LEO are considered. Satellite attitude-controlled motion relative to incoming airflow provides required order change translational motion. The developed allows one track reference trajectories satellites at vertices te...

This paper presents a framework for simulating the flight dynamics and control strategies of the fruit fly Drosophila melanogaster. The framework consists of five main components: an articulated rigid-body simulation, a model of the aerodynamic forces andmoments, a sensory systemsmodel, a controlmodel, andan environmentmodel. In the rigid-body simulation the fly is represented by a system of th...

The calibration coefficients of two commercial anemometers equipped with different rotors were studied. The rotor cups had the same conical shape, while the size and distance to the rotation axis varied. The analysis was based on the 2-cup positions analytical model, derived using perturbation methods to include second-order effects such as pressure distribution along the rotating cups and fric...

This paper responds to research into the aerodynamics of flapping wings and to the problem of the lack of an adequate method which accommodates large-scale trailing vortices. A comparative review is provided of prevailing aerodynamic methods, highlighting their respective limitations as well as strengths. The main advantages of an unsteady aerodynamic panel method are then introduced and illust...

The aerodynamic characteristics of the Coleopteran beetle species Epilachna quadricollis, a species with flexible hind wings and stiff elytra (fore wings), are investigated in terms of hovering flight. The flapping wing kinematics of the Coleopteran insect are modeled through experimental observations with a digital high-speed camera and curve fitting from an ideal harmonic kinematics model. Th...

Abstract-An extended Kalman filter for estimating the states and parameters of a target vehicle undergoing complex motions for use with an integrated guidance-control law is presented. Nonlinear point-mass model of the target including gravitational and aerodynamic forces are considered in the formulation. Target motions are modeled by a second-order oscillatory dynamic system modulating the ae...

Slender high rise structures are exposed to aerodynamic problems connected to the windstructure interaction, for example vortex shedding or dynamic instability (e.g. galloping). Generally the design of these structures requires the aid of wind tunnel tests on scaled models. The paper investigates the aerodynamic behavior of a bluff body and the shape is adopted for section of the tower of a cab...
