摘要

Future development of Boeing's blended-wing-body (BWB) configuration depends entirely on its suitability for carrying cargo, and in the case of a military tanker-transport in particular, its ability to perform airdrop missions. Key to this capability is a cargo door designed to open like a clamshell in the trailing edge. However, it was unclear what effect such door opening in flight might have on airflow around the trailing edge, on engines located on the upper wing surface and on the area around the cargo ramp. Just-completed water-tunnel tests indicate that such a cargo door is viable, providing a boost to the BWB and spurring plans for follow-on wind tunnel evaluations of the same model.
