Due to the random nature of the ship’s motion in an open water environment, the deployment and the landing of air vehicles from a ship can often be difficult and even dangerous. The ability to reliably predict the motion will allow improvements in safety on board ships and facilitate more accurate deployment of vehicles off ships. This paper presents an investigation into the application of art...

This paper focuses on the aircraft landing problem that is to assign landing times to aircraft approaching the airport under consideration. Each aircraft’s landing time must be in a time interval encompassing a target landing time. If the actual landing time deviates from the target landing time additional costs occur which depend on the amount of earliness and lateness, respectively. The objec...

In gymnastics every exercise finishes with a landing. The quality of landing depends on subjective (e.g. biomechanical) and objective (e.g. mechanical characteristics of landing area) factors. The aim of our research was to determine which biomechanical (temporal, kinematic and dynamic) characteristics of landing best predict the quality of landing. Twelve male gymnasts performed a stretched fo...

This Paper is about landing control of legged robot. Body stiffness and damping is used as landing strategy of a legged robot. First, we only used stiffness control method to control legged robot landing. Second control method,sliding mode controller and feedback linearization controller is applied to enhance position control performance. Through these control algorithm, body center of gravity ...

In this research, an automatic control system is designed for landing of a small helicopter on a 4 DOF moving platform. The platform has three translational and one directional degree of freedom. The controller design approach is based on development of helicopter nonlinear dynamic model into the SDC (State Dependent Coefficient) form and real time solving of state dependent Riccati equation (S...

Virtual risk experiences have been proposed in persuasive technology as an approach to change people’s attitudes and behaviors concerning safety topics. This paper advances the investigation of virtual risk experiences in different directions. First, we extend the study of their effects to safety locus of control, which is an important predictor of an individual’s attitudes and behaviors with r...

This paper presents a novel solution for micro aerial vehicles (MAVs) to autonomously search for and land on an arbitrary landing site using realtime monocular vision. The autonomous MAV is provided with only one single reference image of the landing site with an unknown size before initiating this task. We extend a well-known monocular visual SLAM algorithm that enables autonomous navigation o...

Introduction: We have explored the use of GIS suitability models for the screening and analyzing of potential sites for Mars landers using engineering and scientific constraints in an iterative manner. While initially performed on locally held data sets, these analyses have now been extended to use widely distributed data from standardized Web Mapping Servers (WMS) [1]. The ability to exploit a...

Landing gear is a structural component of an aircraft to support the weight while it is on the ground and also to aid safe landing. A generic analytic model for linear dynamic analysis of landing gears, which captures responses of individual components, is seldom available in literature. In the present work an analytical model for the linear response analysis of landing gear is developed. The l...
