Autonomous control of uninhabited air vehicles (UAVs) presents a number of challenges, including detecting failures across the entire flight regime/mission envelope, differentiating between behavioral changes due to failures and those due to uncertainties, real-time control law redesign, and real-time modification of UAV trajectories and sensor-allocation strategies. Barron Associates, Inc. ...

Flight test experience shows that for highly-agile controllers, pilots who do not -induced oscillations (PIOs) due to actuator rate limits and other system lags. The problem is further exacerbated in remotely-piloted vehicles where pilots lack the physical cues that assist in self-limiting. Recent research has developed techniques for ant ...

The development of control laws for control of UCAVs in formation requires knowledge of the complete multivehicle dynamical system. This Phase I effort focuses on the design and development of simulation models for multiUCAV situations. During the primary work phase of this effort, a limited wind-tunnel entry in the Langley Full-Scale Wind Tunnel will be performed to demonstrate the ability to m ...

The Uninhabited Combat Air Vehicle (UCAV) is a new and promising multi-role and multi-mission system concept currently under development and evaluation by the armed forces. Similar to current generation of weapon systems, simulation of the UCAV mission profile will undoubtedly be an essential part of the system development process. Further, the rapid pace of their development and the evolution of ...

Spinal injury (vertebra fracture) during aircraft ejection or vertical helicopter crash is a serious problem due to the human body's inability to tolerate excessive +Gz acceleration. Although anthropomorphic test devices (ATD) or manikins have been used to assess, develop and standardize ejection seat and crash safety, they do not represent the spinal response under high acceleration loading. Fle ...
