Close-up of a bow thruster on an AP1-88. This (starboard) thruster and its counterpart (port) can be rotated through 360°, allowing precise control of yaw when stationary or in motion. Fed by bleed air from the lift system these bow thrusters are aligned facing aft during cruise to give maximum thrust. Here they are shown rotated to the starboard aiding in lateral movement on land. For braking, they can be swivelled to oppose the direction of travel of the craft, and act akin to thrust reversers Back to AP1-88 hovercraft page
