Abstract—In recent decades, flapping wing aerodynamics has attracted great interest. Understanding the physics of biological flyers such as birds and insects can help improve the performance of micro air vehicles. The present research focuses on the aerodynamics of insect-like flapping wing flight with the approach of numerical computation. Insect model of hawkmoth is adopted in the numerical s...

Control actuators' faults are among the major reasons to lose aircraft control while flights. The plane dynamics is severely dependent upon faults and errors in flight control systems and if the reformed control order is not issued by the fault tolerant controller there would be unpleasant outcomes such as inconsistency and the reduction of system performance and some dreadful aerial accide...

A wing-payload system is a two-body flight vehicle with a payload suspended below the wing through a large number of suspension lines. The present study gives a detailed description of 4-DOF longitudinal flight dynamic model of the wing-payload system. The aerodynamic coefficients of the wing are generated using CFD simulations whereas those of the payload are estimated from empirical relations...

We study the dynamics of the relative motion of satellites in the gravitational field of the Earth, including the effects of the bulge of the Earth (the J2 effect). Using Routh reduction and dynamical systems ideas, a method is found that locates orbits such that the cluster of satellites remains close with very little dispersing, even with no controls. The use of controls in the context of thi...

Autonomous helicopter flight represents a challenging control problem, with complex, noisy, dynamics. In this paper, we describe a successful application of reinforcement learning to autonomous helicopter flight. We first fit a stochastic, nonlinear model of the helicopter dynamics. We then use the model to learn to hover in place, and to fly a number of maneuvers taken from an RC helicopter co...

A monocopter, which is a biology-inspired aircraft based on the samara, has been proved to have passive flight stability. However, due asymmetry of its configurations and constant rotation during flight, dynamics equation complex. In this paper, longitudinal stability monocopter systematically analyzed. The motion used as main research object in paper. By transforming body axis coordinate frame...

Militarized versions of commercial platforms are growing in popularity due to many logistical benefits in the form of commercial off-the-shelf (COTS) parts, established production methods, and commonality for different certifications. Commercial data and best practices are often leveraged to reduce procurement and engineering development costs. While the developmental and cost reduction benefit...
