Alcore Technologies



The Alcore Technologies Undersea Motor-Glider is design for a range of oceanographic and defence missions. The strategy to glide with wings, flying up and down (change in buoyancy) under the sea with density variation procures very low level power consumption. The autopilot adjusts the ballast with external control ailerons for control the flight undersea. An electric motor with propeller retractable blades, secure the mobility and agility of the system. The long endurance capability is associate to a wide range of sensors, for a number of applications.
