A Modelica Library for Space Flight Dynamics

The Modelica Space Flight Dynamics Library has been developed as a unified environment to be used throughout the design cycle of the Attitude and Orbit Control System (AOCS) for a generic multibody, possibly flexible, spacecraft. The library architecture has been recently redesigned, exploiting at its best Modelica’s reusability, flexibility and modularity features. In this contribution the mai...

Improved Mathematical Model for Helicopters Flight Dynamics Applications

The purpose of this paper is concerned with the mathematical model development issues, necessary for a better prediction of dynamic responses of articulated rotor helicopters. The methodology is laid out based on mathematical model development for an articulated rotor helicopters, using the theories of aeroelastisity, finite element and the time domain compressible unsteady aerodynamics. The he...

ETS-VII Flight Experiments For Space Robot Dynamics and Control

The Engineering Test Satellite VII (ETS-VII), developed and launched by National Space Development Agency of Japan (NASDA) has been successfully flown and carried out significant experiments on orbital robotics with a 2 meter-long, 6 DOF manipulator arm mounted on this un-manned spacecraft. The ETS-VII should be noted as one of remarkable outcomes of the research effort on space robots, particu...

Impact of Ada and Object-oriented Design in the Flight Dynamics Divisionat Goddard Space Flight Center

Evolving the Reuse Process at the Flight Dynamics Division (FDD) Goddard Space Flight Center

This paper presents the interim results from the Software Engineering Laboratory's (SEL) Reuse Study. The team conducting this study has, over the past few months, been studying the Generalized Support Software (GSS) domain asset library and architecture, and the various processes associated with it. In particular, we have characterized the process used to configure GSSbased attitude ground sup...
