Tandem wing ground-effect wing ship

Abstract

The invention belongs to the technical field of ground-effect wing ships, and particularly relates to a tandem wing ground-effect wing ship. Mechanisms such as the high-speed planing boat, the ground-effect wings and the side plates are combined for use, so that triphibian sailing becomes possible. The structural characteristics of the ship body are fully utilized, the air layer resistance reduction technology is reasonably arranged and utilized, and the fault steps and the relatively-closed ship bottom are matched, so that the air layer stably exists, and the water surface resistance is greatly reduced; the air ducts of the ducted propeller thrusters directly face the front wings of the tandem wings, power hover is generated through thrust and wake flow generated by the ducts, and the dynamic lift force of the tandem wing ground-effect ship is improved; the front wings of the tandem wings are arranged upwards, the rear wings of the tandem wings are arranged downwards, the height difference is formed, downwash airflow of the front wings accelerates airflow on the upper surfaces of the rear wings, the lift force of the rear wings is enhanced, the front wings and the rear wings generate positive lift force, the center is located between the two wings, balance during flight is maintained while the lift force is generated, and balancing resistance is avoided.

Description

Technical field [0001] The invention belongs to the technical field of ground effect wing ships, in particular to a tandem wing ground effect wing ship. technical background [0002] In recent years, researchers have invented the powered hovercraft and powered hovercraft by integrating the air cushion technology into the ground effect wing craft. The above-mentioned ship types are amphibious and have higher transportation efficiency at the medium speed of 150km / h-250km / h. For the research of small ground-effect wings, researchers also try to use air cushion and other technologies to improve their take-off and landing and stable cruise performance. [0003] At present, the research and promotion of high-efficiency wing-in-ground ships at home and abroad are still at an early stage, which needs the support of other knowledge in different fields. In fact, the technology of WIG ship is still in the experimental stage and needs to be converted to the practical stage. This conversion a...
