Computational Challenges in Simulating Powered Flight of the Orion Launch Abort Vehicle
Some of the simulation work performed by the computational aerosciences project under the NASA Constellation program is presented. The challenges of simulating the powered flight of the Orion launch abort vehicle for the purposes of building an aerodynamics database are discussed. During an abort this vehicle fires both a four-nozzle abort motor together with an eight-nozzle attitude control mo...
متن کاملCalculating Launch Vehicle Flight Performance Reserve
This paper addresses different methods for determining the amount of extra propellant (flight performance reserve or FPR) that is necessary to reach orbit with a high probability of success. One approach involves assuming that the various influential parameters are independent and that the result behaves as a Gaussian. Alternatively, probabilistic models may be used to determine the vehicle and...
متن کاملEvaluation of an Adaptive Method for Launch Vehicle Flight Control
the amount of analysis and testing required per mission must be reduced over that performed for the partially re-usable Space Shuttle. A goal for future RLV flight control is to design and test the flight control system to operate within a prescribed flight envelope and loading margin, and requiring only payload/fuel parameters and “route” to be specified for a given mission. It has been estima...
متن کاملLimited Adaptive Authority Flight Control for the Crew Launch Vehicle
The control system of the NASA Crew Launch Vehicle is designed to meet performance and robustness requirements during its ascent flight phase. However, the controller bandwidth and the attainable level of robust performance is limited by the degree of flexibility inherent in the long and slender design that has been adopted for this vehicle. Since there remains a substantial degree of uncertain...
متن کاملSelf-configuring Network for Launch Vehicle and Satellite Avionics
Under an Air Force Phase II SBIR contract, Microcosm is developing a self-configuring avionics network, scheduled for test on a sounding rocket in late 2003 or early 2004. This system is extendable to spacecraft avionics and housekeeping functions, enabling true plug-and-play capability.
