Abstract
The invention relates to a control system for an air cushion vehicle (400) for the purpose of improving maneuverability of the air cushion vehicle. The system includes four propeller towers (401-404), propellers installed at the propeller towers, and mounting seats for mounting the propeller towers to the air cushion vehicle. In the system, an edge portion (442) located closest to a side wall N of the air cushion vehicle in the mounting seat is located closer to the ground than an opposite edge portion (446) in relation to a pivot point in the mounting seat, providing a tilt (450) of the propeller in response to rotation of the mounting seat at the pivot point, and in response to the rotation of the mounting seat, the propeller tower directs an air flow (452) produced with the propeller over the side wall of the air cushion vehicle and, due to the tilt of the propeller, partly downwardly relative to a horizontal plane defined by the ground, the air flow exerting a force (462) that lifts the side wall of the air cushion vehicle upwardly from the ground.
