2、he project, which focused on technology demonstration, needed to decide whether to use a full size or scale model aircraft to achieve its research objectives. The decision would determine the complexity, cost, time, and test procedures necessary to achieve the objectives. The project used several fa

3、ctors to determine the final outcome. Several of particular importance were: a71 Most of the technology had been researched and developed in previous and extensive bench or wind-tunnel studies. The project would only be integrating them into a flight vehiclea71 A manned flight vehicle was not a requ

4、irementa71 The project would be tested in a remote and unpopulated flight test area Lesson(s) Learned: The project was able to reduce its risk and optimize its cost and schedule by using scale versus full size flight vehicles.Recommendation(s): Technology demonstration flight projects that are prima

5、rily responsible for integrating technologies already demonstrated individually should consider using scale models, especially when there is no requirement for manned flight or for test operations in high-risk areas.
