From page 71...
... The ARL and VTD leadership is effectively moving forward in the face of these major events. In addition to the fiscal and facilities changes, planned program changes include reduced activities in some technologies (e.g., active rotor technology development and large-turbine-engine concepts)
From page 72...
... simulation of compressor stall avoidance and the work on hot restart is excellent work that addresses near-term operational issues and provides a sound foundation for future developments and more refined research. A second example of a significant advancement is the Robotics Collaborative Technology Alliance.
From page 73...
... VTD has a window of opportunity because of the changes dictated by the BRAC to ensure that all of its programs across the VTD divisions mutually support one another and that all programs are aligned to meet the needs of the Army. For example, the Robotics CTA is an excellent program that is clearly demonstrating an approach that is producing a great leveraging of ARL's limited funds and personnel to produce the artificial intelligence and vision necessary for a robot to autonomously get from point A to point B
From page 74...
... presents new opportunities and challenges to the task of establishing methodology. For example, while the organizational research model is to be applauded and the notable per-project success rate within the Robotics CTA is to be recognized, there are a number of broader issues that VTD and ARL might wish to consider as this and similar activities move forward.
From page 75...
... And the development of analytical and computational methodologies and capabilities is a clear investment in future design and development capabilities, especially for active rotor design, tiltrotor aeroelasticity, high-resolution CFD, and a host of nonlinear problems associated with technologies such as flapping wings. Examples of this work include the ­Parallel Unsteady Domain Information Transfer effort and the development of robot algorithms for uncertain environments.
From page 76...
... This work would benefit from the identification of a path that will distinguish this effort from others in this area. One opportunity that does exist is to seek collaboration in the upcoming NASA Ames Research Center testing on Boeing and Sikorsky active rotors (which may be in advance of the next VTD active twist rotor test in late 2009)

This material may be derived from roughly machine-read images, and so is provided only to facilitate research.
