Improving GEV Aerodynamic Quality by Enveloping Sea Waves
Abstract
Introduction: One of the main problems hindering the wide introduction of Ground Effect Vehicles to the world market is their high sensitivity to sea waves. This prevents the implementation of safe and cost-effective freight and passenger transport over long distances above the water surface. Purpose: Developing a method for enveloping the sea waves by a vehicle, and assessing its effectiveness. Methods: Mathematical modeling based on a predetermined probability of a collision between a GEV and the sea surface; simulation to determine the permissible reference flight altitude above the sea for a controlled GEV. Results: A method for enveloping the crests of sea waves is proposed which can increase the aerodynamic quality of a GEV and reduce the probability of its collision with a wave when the sea is disturbed. The essence of the method is laying a vehicle trajectory along the sea wave chutes by moving in the direction of the minimum gradient of the underlying surface in a certain sector whose direction coincides with the direction to the final point of the route. Practical relevance: The proposed method allows you to improve the flight safety and aerodynamic quality of a GEV and, hence, to reduce its fuel consumption.Published
