A mission simulation prototype for Distributed Space Systems has been constructed using existing developmental hardware and software testbeds at NASA's Goddard Space Flight Center. A locally distributed ensemble of testbeds, connected through the local area network, operates in real time and demonstrates the potential to assess the impact of subsystem level modifications on system level performance and, ultimately, on the quality and quantity of the end product science data.

This paper outlines the algorithm behind the Safety Board's kinematics parameter extraction code. The Metrojet flight 2710 incident1 will be used as an example of the use of this method when control surface deflections were not recorded. The study of this incident also provides a comparison with the conventional simulation method. The Alaska flight 261 accident2 illustrates the use of the kinematics parameter extraction method when the recorded stabilizer parameter had exceeded the sensor range. This accident also illustrates the adaptation of the basic kinematics code to calculate loads on the stabilizer jackscrew.

Unmanned aerial vehicles (UAVs) are playing an important role in today's military initiatives. UAVs have proven to be invaluable in locating critical targets and reporting enemy movements or positions to battlefield commanders. Integration of new technologies necessitates simulation prior to fielding new systems in order to avoid costly errors. The unique nature of UAVs in a modern combat environment requires the simulation of a significant part of the battle space to test the robustness of new technologies. Furthermore, simulation environments should be flexible and generic to allow for expedient testing of a wide range of concepts. Members of the Air Force Research Laboratory (AFRL) at Wright-Patterson AFB are developing a multi-purpose simulation environment that will allow for the assessment of many different types of UAV technologies. This paper discusses this simulation activity and describes how it fits into AFRL's corporate plan.
Distributed interactive simulation is an innovative technology for the development of space projects. Because of the specific demands for space projects, the basic simulation protocol standard requires additional rese...

The AVTAS Laboratory, located in the Air Force Research Laboratory's Air Vehicles Directorate at Wright-Patterson AFB, Dayton Ohio, is rapidly expanding on its traditional flight control and flying qualities research emphasis by creating simulation Based Research & Development (SBR&D) environments, tools, and processes where researchers and warfighters can assess and evaluate advanced aerospace vehicle technologies and concepts during simulated missions. AVTAS researchers now conduct mission, engagement, and campaign level simulations as needed to demonstrate military utility and to guide/prioritize AFRL investment strategies. Both virtual and constructive simulations1 are used to conduct capabilitybased assessments of AFRL and VA technologies. The AVTAS vision is to quickly and accurately evaluate anything AFRL researchers can imagine and to identify high payoff technology investment paths. Included in this, is the demonstration of the benefits of advanced technology to current and future systems.
