Aeronautical and Space Vehicle Control in Dynamic Sliding Manifolds

International Journal of Control, 2003
Abstract Multiple loop multiple time scale sliding mode control technique based on dynamic sliding manifold is developed and applied to aeronautical and space vehicle control. Minimum and nonminimum phase output tracking problems for aeronautical and space vehicles are addressed in dynamic sliding manifold. Numerical examples of the flight controller

Calibration of Antenna Arrays for Aeronautical Vehicles on Ground

Aerospace Science and Technology, 2013
Abstract Antenna pattern and characteristics change significantly when antenna arrays are placed on platforms like aeronautical vehicles. Calibration of antenna arrays is an important and costly process for such cases. In this paper, a method is proposed for the offline calibration of a direction finding antenna array mounted on a UH-60 helicopter ...

Propellant Technologies: Far-Reaching Benefits for Aeronautical and Space-Vehicle Propulsion

Journal of Propulsion and Power, 1998
Rocket propellant and propulsion technology improvements can be used to reduce the development time and operational costs of new space-vehicle programs. Advanced propellant technologies can make the space vehicles safer, more operable, and better performing. Five technology areas are described: monopropellants, alternative hydrocarbons, gelled hydrogen,

An Aeronautical Ad Hoc Network Routing Protocol Based on Air Vehicles Movement Features

2016 22nd International Conference on Applied Electromagnetics and Communications (ICECOM), 2016
To solve the problem that the current routing protocols in MANET cannot be used in AANET (Aeronautical Ad Hoc Networks), we propose the Hierarchical Space routing protocol (HSRP). Section 1 of the full paper gives five definitions that we have come up to find useful in describing HSRP protocol.

Towards a Federated Simulation Approach for Reliability Evaluation of Unmanned Aircraft Vehicles Within Aeronautical Communcations Networking

2011 IEEE 30th Symposium on Reliable Distributed Systems Workshops, 2011
This paper introduces a modeling framework for the analysis of safety and resiliency properties of Unmanned Aircraft Vehicles within Aeronautical Communications Networking (ATN). It first depicts the system under analysis. Then it presents an overview of the framework, showing its building-blocks and their interactions.
