Performance Prediction Method for a Wing-in-Ground Effect Vehicle with Blowing Under the Wing.

摘要

Recent efforts in theoretical analysis and experimental observations have moved the concept of power-augmented flight in ground effect toward practicality. With the addition of lift and drag due to external airflow, end-plate leakage, water skin friction, wave drag effects, and wave clearance constraints, a flow model can be made capable of effective comments. The analysis shows that there are wave drag and wave clearance related limits to many aspects of the vehicle configuration. The most important of which are cruising height and aspect ratio, in that they have a very large effect on transport efficiency. Unfortunately, the low flying high aspect ratio cases are ruled out due to wave impact problems. Testing of a point design vehicle, arrived at through the use of analysis such as the one of this report, needs to be performed as final verification of the accuracy of the design procedure. (Author)
